Chasing the Wind

[From Kenny Kitzke (2009.23.2100EDT)]

I am of the opinion that the hope of developing an accurate model for how the economy of the USA (or any nation for that matter) works is wishful thinking. As valuable as PCT and closed loop analysis is, it will be like chasing the wind and is an improbable or impossible dream.

To start some thinking about this premise, I will raise just five points for now:

  • is the economic system a closed-loop system? Was not the USA depression, or its steady rise to the most prosperous nation in the world in less than a century proof of an open-loop system?
  • is the elemental basis for an economy what producer people and consumer people do? Or, since the economy of a nation is always measured in monetary units, is it more sensible to start with people who make financial transactions, generally called buyers and sellers?
  • is an inanimate economic system subject to the rules of PCT? Do people individually, or even collectively, control the economic system performance or does the economic system constrain and control what people want and can do?
  • if we want someone to build a model of a system, would we want that someone to be a novice or someone who has worked tirelessly to know all there is to know about the real system and how it has performed historically? Would we ask a entomologist to make a model of our country’s human health care system?
  • is there anyone who believes that a country’s economy is an independent variable? Or, is it obvious that different economic systems in many nations work differently and affect the economic system performance in any one country?
    The kind of person I would want to make a new economic model would be someone who is steeped in economic systems, their components and their historic performance. Data is helpful but a working model to me would also have to include a theory of how the components of the economic system interact. When you run the model, aren’t you really testing the theory in the model to know whether it accurately duplicates what has been historically observed?

Here are some simple questions about national economies that might reveal whether someone is aware of and steeped in how economic systems perform and work, and produce superior results than other systems and other nations.

  1. What nation has the largest economy in the world? What has that nation done that makes its results so much more superior than even #2?
  2. What are the top ten largest economies in the world? What economic system do each of them use? Is there ranking primarily related to the economic system enforced in their country by the government or by the actions and efforts of its citizens?
  3. If we look at productivity per citizen rather than just size, what are the top 20 nations in GDP per citizen? How do we explain the differences?
  4. What nations have the largest markets for products and services? What nation has the largest market for automobiles in 2009? What role does market size play in an national economy versus the gross domestic product or production capacity of that country?
  5. What measure of economic performance in a nation is the most vital in the quality of life experienced by its citizens?
    I honestly don’t know why we would expect someone with little practical knowledge of various economic systems, or their differences, or how they have performed relatively to do a valuable job of creating a model to explain the actual and prospective working of the economy in any given country.

I long for a coherent explanation from Bill. Perhaps I just don’t get it? If I wanted to create a model for the most sensible and economic way to produce and consume electrical power and energy, I would not seek the best chef in the country. The smartest and most powerful financial economists in the world are right here in Pittsburgh this week. Shouldn’t they be guiding and funding development of a new economic model. I suspect that less than a percent of the money they are spending while in Pittsburgh would put a world-class model development team together that could devote all the time and resources necessary to get the best model possible in the least amount of time. If a model really is possible and needed, would it not be obviously worthwhile to get the proposal defined and accepted for action?

What is the restraint? Why would that be resisted as a disturbance to what reference perception? I wish I knew but about all I can do is guess. I can guess about chasing the wind and hope I might discover an accurate model of where it comes from or where it goes, but there seems to be more worthwhile ways to spend my time.

BP: I think there’s something more than meets the eye here. Why would you
be so adamantly against even trying to develop an economic model? It
sounds to me as if you fear not that it might fail, but that it might
succeed. If a successful economic model were to be created (by anybody,
not just PCTers), it would be the first one, and because of that would
probably show that a lot of lines of thinking about economies were simply
wrong, or on the wrong track. I can see that as a reason why someone who
has strong beliefs about economic systems might not want to risk seeing a
model that works as the real economy works. But you don’t strike me as a
person who would be against a successful scientific project just because
it might make us change our minds about something. You’ve always said
you’re open to any new ideas. So why this energetic attempt to get us to
drop the economic modeling effort? I won’t try to guess, but it’s a
question that needs an answer.

KK: To start some thinking about
this premise, I will raise just five points for now:

is the economic system a closed-loop
system? Was not the USA depression, or its steady rise to the most
prosperous nation in the world in less than a century proof of an
open-loop system?

BP: No, it was not, any more than the occurrance of periodic wars shows
they are signs of open-loop systems. Those were consequences of how the
people in the USA and elsewhere interacted with each other. And people
are control systems, not open-loop systems.

KK: is the elemental basis for an
economy what producer people and consumer people do? Or, since the
economy of a nation is always measured in monetary units, is it more
sensible to start with people who make financial transactions, generally
called buyers and sellers?

BP: Definitely it is what buyers, sellers, producers, and consumers of
goods and services do. These are all living human control systems and
everything that happens in economies happens only because of what these
people want and perceive and do. An economy is not some mysterious
machine operated by invisible rules or jerked around by some invisible
puppeteer. We have met the economy and it is us. It is what people do as
they try to control what happens to them. The economy is just one special
case of human behavior.

KK: is an inanimate economic system
subject to the rules of PCT?

BP: There is no inanimate economic system. If you remove the people,
there is no economy.

KIK: Do people
individually, or even collectively, control the economic system
performance or does the economic system constrain and control what people
want and can do?

BP: The people, individually and collectively, create and sustain the
interactions we call economics. The people ARE the economic system; what
they want and do is the engine that drives economics, and that totally
determines the economic processes we observe.

KK: if we want someone to build a
model of a system, would we want that someone to be a novice or someone
who has worked tirelessly to know all there is to know about the real
system and how it has performed historically? Would we ask a
entomologist to make a model of our country’s human health care
system?
KK: is there anyone who believes
that a country’s economy is an independent variable? Or, is it
obvious that different economic systems in many nations work differently
and affect the economic system performance in any one
country?

BP: I would greatly prefer an open-minded novice who understands modeling
to create the model, rather than someone who has built up a store of
prejudices and incorrect rules of thumb because of not having a proper
model and therefore not understanding what is really going on. Would you
rather have an effort to model human behavior run by 100 behaviorists
with 50 years each of experience studying behavior, or a naive engineer
who happens to know about control theory?

BP: I don’t care what anyone believes; they can and do believe anything
imaginable. I care about what they can demonstrate to be true. An economy
consists of all the dependent variables that people control, all the
reference conditions that specify how they want those variables to be,
all the physical laws that connect actions to their consequences, and all
the biological laws that enable human beings to exist and work as they
do. All economic systems, however different they may appear, work because
of these elements of human behavior. The differences arise from
differences in goals, perceptions, and available means of control, not
because the dirt inside the boundaries of Albania contains an Albanian
economic system and so on country by country.

KK: The kind of person I would want
to make a new economic model would be someone who is steeped in economic
systems, their components and their historic
performance.

BP: That would not give you a model; it would give you a defense of the
most authoritative misconceptions that precede the first successful
model. In 1491, the consensus among experts was that Columbus would sail
right off the edge of the world into an abyss. When great increases in
our understanding occur, inevitably it is the experts who are proven
wrong, because they became expert in what was previously believed and,
most probably, argued vehemently against the new understanding as it
began to take shape. Therefore I would not turn the construction of a
model of the economy over to people steeped in the old ways of thinking
and who know only the history of economics – though I would consult them
on matters of fact.

KK: Data is helpful but a working
model to me would also have to include a theory of how the components of
the economic system interact. When you run the model, aren’t you
really testing the theory in the model to know whether it accurately
duplicates what has been historically observed?

BP: Absolutely, that is precisely what we do in generating any working
model. We make a guess as to how the model should be organized (how its
components should interact), fill the model in with any imaginary
properties it needs in order to run, and run it. Then we compare what the
model did with what the real system did and look for all the differences
we can find. We use historical data for this because predictions would be
futile until we can at least make the model match what has already
happened. That’s just standard practice in the physical sciences and
engineering. That is exactly how I would organize the development of an
economic model, and how I’ve already described the project, in case you
missed it.

As we modify the model to eliminate the differences from real data, we
begin to understand the real system better, and see where the basic
organization of the model may need revision. So around and around we go,
model, data, test, revise, model, data, test, revise … each time making
the model more like the real system. This process can converge to some
pretty good models. It gave us modern physics and chemistry.

KK: Here are some simple questions
about national economies that might reveal whether someone is aware of
and steeped in how economic systems perform and work, and produce
superior results than other systems and other
nations.

BP: What’s this obsession with being superior to other systems and other
nations? Who cares who we’re superior to? Is this some kind of
king-of-the-hill contest? Don’t you know you’re well off without having
someone much worse off to point to? I’d like to see everybody happy and
satisfied, wouldn’t you? Isn’t it a little embarassing to sit at the
banquet table burping and picking your teeth while others watching you
are starving? Or does that just make sitting at the banquet table seem
even better? It makes me uncomfortable.

KK: What nation has the largest
economy in the world? What has that nation done that makes its
results so much more superior than even #2?

BP: From the adjectives you use, I would guess that
that nation just wants to be better than everybody else. Is there
something to admire in that?

    1. If we look at productivity per citizen rather than just size, what
      are the top 20 nations in GDP per citizen? How do we explain the
      differences?
  1. What nations have the largest markets for products and
    services? What nation has the largest market for automobiles in
    2009? What role does market size play in an national economy versus
    the gross domestic product or production capacity of that country?
  2. What measure of economic performance in a nation is the most vital in
    the quality of life experienced by its citizens?
    KK: What are the top ten largest
    economies in the world? What economic system do each of them
    use? Is there ranking primarily related to the economic system
    enforced in their country by the government or by the actions and efforts
    of its citizens?
    BP: Ah, the last one strikes a chord. Certainly it’s not the lavish
    riches we wallow in. I’d say that friendship and love, respect for other
    human beings, understanding human nature, appreciation of beauty and
    knowledge, and seeking new frontiers are among the top measures of
    quality of life. Having a lot of money without those things wouldn’t mean
    much. Being better than everybody else certainly isn’t among them.
    Neither is selfishnes or self-congratulation or self-importance or
    self-aggrandizement. Read the Bible – Jesus told us what matters.
    Consider the lilies of the field; they toil not nor do they spin, yet
    they are just as important in the human economy as the highest priest or
    the Roman emperor. A rich man has about as much chance of getting into
    Heaven as a camel has of passing through the eye of a needle. I don’t
    know if Jesus was the son of God, I think not, but he was pretty far
    ahead of his time. It’s not surprising that he got in trouble with the
    Establishment – just about every Establishment there was at the time.
    Even his own people chose Barrabas.

I honestly don’t know why we would
expect someone with little practical knowledge of various economic
systems, or their differences, or how they have performed relatively to
do a valuable job of creating a model to explain the actual and
prospective working of the economy in any given
country.
I long for a coherent
explanation from Bill. Perhaps I just don’t get
it?

Well, I’ve told you what I think.

Maybe you don’t. I don’t know – you’re there inside of you, and I’m out
here. You have expressed your preferences pretty well in your post, and
I’ve rejected most of them, so you should have a pretty good idea of what
I get and don’t get, though you can’t know, either.

If I wanted to create a model
for the most sensible and economic way to produce and consume electrical
power and energy, I would not seek the best chef in the country.
The smartest and most powerful financial economists in the world are
right here in Pittsburgh this week. Shouldn’t they be guiding and
funding development of a new economic model.

Good God, NO! Aren’t you forgetting what these financial geniuses have
just finished doing to us from behind? Those of them who weren’t the
leaders in causing the crashes didn’t do a thing to stop the disasters
because they had no more idea of how the system works than the janitor
who cleans up after them has. All they have is a lot of superstitions and
business-school mottos to back them up. Expand or die, yeah, sure.
Indifference curves, oh boy. They know what to expect from each other, of
course, which is why they don’t trust each other. I’m not saying they’re
stupid; they’re just full of facts that ain’t so. There is no
“law” of supply and demand. There are only people who want
things and act however necessary to get them. But economists know nothing
about people, so they try to formulate economic theories with no people
in them. That’s why there is no economic model yet (apologies to the new
agent-based economic theorists, who are trying to put the people back
in).

It’s a lot of fun to exaggerate and I don’t apologize.

I suspect that less than a percent
of the money they are spending while in Pittsburgh would put a
world-class model development team together that could devote all the
time and resources necessary to get the best model possible in the least
amount of time. If a model really is possible and needed, would it
not be obviously worthwhile to get the proposal defined and accepted for
action?

Your faith is touching but misguided. The vast knowledge you imagine
doesn’t exist. It’s not that these guys don’t know anything:
obviously they know an enormous amount. They just don’t know about the
important and essential things, such as people being control systems. And
I’ll bet there isn’t one of them that knows how to construct and test a
model (do you?). Without that missing knowledge, the rest of what they
know is useless.

What is the restraint? Why
would that be resisted as a disturbance to what reference
perception?

Very simple: I don’t agree with your assessment of the abilities of these
people. I don’t think they know how to construct a model. I don’t think
that much of what they know is true. I don’t think they know how people
work.

I wish I knew but about all I
can do is guess. I can guess about chasing the wind and hope I
might discover an accurate model of where it comes from or where it goes,
but there seems to be more worthwhile ways to spend my
time.

I can agree with that. I take it that you’re not volunteering your
services to the model-building team. Go play tennis with David.

I really love you, Kenny, but sometimes you can be a pain in the neck.
Well, so can I.

Best,

Bill P.

[From Kenny Kitzke (2009.09.23.1000EDT)]

Here is an economic fact. The “official” unemployment rate in Pittsburgh (south-western PA) is 2% below the national average. Dick would like to know why. So would I.

I just watched the Mayor of Pittsburgh on MSNBC bragging about the role his administration played in leading Pittsburgh out of the ashes to this laudable result. What great change and what great spin! Perhaps he should be president instead of O’bama?

Here are some other facts I will share with you about the Pittsburgh economic miracle.

  • the city of Pittsburgh is essentially bankrupt and under the control of the state of Pennsylvania
  • the only city in the USA to lose more population last year than Pittsburgh was New Orleans. Do we need a new economic model to understand why?
    How much of the superior unemployment result was due to the leaving of people who had no job? How much was due to changing tax policy by the Democrat mayor? I suspect that these answers are unknown and unknowable. I suspect there is no identifiable root cause. I suspect it may be a statistical aberration. Some cities will be higher and lower than the average in any time frame. I also know how to test whether there is a special cause or if it is just a common, many faceted cause, within the economic system that exits in Pittsburgh compared to all the other nations cities. Even that knowledge and determination will be subject to error, possibly 3-5%. But, I suspect that neither the mayor, nor the economic summit experts, would know how to do this and the error rate of their suggestions could easily be an order of magnitude greater. Do they know how to analyze data accurately? Do they know the difference between casting nets and testing specimens? Or, are they all here for the show to promote themselves and their own purposes.

Will the promoters on CSGNet of creating a new economic model please speculate how their model, initially or even ultimately after years of adjustment and expansion, will clearly and accurately explain this economic employment phenomena in Pittsburgh? Or, will they just chase the wind like the politicians and economic ministers using a different incomprehensible method?

[From Fred Nickols (2009.09.24.1144 EST)]

No disrespect intended, Kenny, but you're starting to sound like a guy who suddenly realized that a great deal of what goes on in the world is pure B.S. Your mayor is taking credit for a figure that might not even be correct. But he's a politician and that's what politicians do. Surely, you don't expect them to operate on the basis of data? I don't and I don't want them to. Why? Because good data are terribly difficult to come by and most of what's out there is the result of cooking the books in one form or another, much of it "cooked" by supposedly respectable researchers.

A fellow I know has a tag line that reads "In God We Trust; all others must provide data." I, for one, don't trust the data - unless I've gathered it myself and even then I'm skeptical.

BP: What's this obsession with being superior to other systems and other
nations?

It's one of the right-wing talking points. I've had the misfortune of
reading some of this stuff lately in an effort to try to understand
what right wing friends (well, acquaintances) of mine actually
believe. My racquetball partner is one of them and I asked him to
refer me to some articles that would help me understand the principles
of conservatism, in which he now believed so deeply, so we can discuss
it over lunch (I've known this guy for 10 years and I still have no
idea why a nice Jewish boy like him -- who is proud to say that he was
at Woodstock, yet -- would get into what appears to me to be such an
ugly belief system). The articles he sent turned out to contain pretty
incoherent stuff. Basically, it can be summed up as: the US is the
greatest country in the world (Kenny's point), the government is the
enemy, taxation (especially taxation of the wealthy) is theft, helping
the poor is bad (because it creates a cycle of dependence), helping
the rich is good (because they are the people who create jobs for
those lazy poor people), the "free market" is the best economic
system, freedom means the freedom to own a gun and this is a Christian
nation (Jews are OK now, too ).

What measure of economic performance in a nation is the most vital in the
quality of life experienced by its citizens?

BP: Ah, the last one strikes a chord. Certainly it's not the lavish riches
we wallow in.

This struck a chord in me as well. There have been various approaches
to measuring quality of life. I personally like the simple-minded
"happiness" index, which is just the answer to the question: "Taking
all together, how satisfied or dissatisfied are you [on a 1 - 10
scale] with your life as a whole these days"? By this measure of
quality of life, the US ranks 34th (for those who are keeping score).

My model of the economy provides a way to measure "quality of life" in
terms of control rather than monetary measures, such as GDP/capita.
Each agent is a controller with reference levels for the
goods/services that are produced by itself and the other agents. To
the extent that each agent is able to keep the error in all controls
systems at zero, the quality of life is good: the economy is working
perfectly in that it is providing enough income (from sales) to each
agent so that all agent can purchase their reference amount of goods
and services. To the extent that some agents do not have enough money
to control for their reference amounts of goods and services, the
quality of life (in terms of the agents' ability to control their
inputs) is compromised. The model will make it possible to determine
which factors affect the quality of life (agents' ability to control)
provided by an economy.

Best

Rick

Interesting questions. i would like to comment on just one. Near the end you said

The kind of person I would want to make a new economic model would be someone who is steeped in economic systems, their components and their historic performance. Data is helpful but a working model to me would also have to include a theory of how the components of the economic system interact. When you run the model, aren’t you really testing the theory in the model to know whether it accurately duplicates what has been historically observed?

I honestly don’t know why we would expect someone with little practical knowledge of various economic systems, or their differences, or how they have performed relatively to do a valuable job of creating a model to explain the actual and prospective working of the economy in any given country.

I remember an article, many years ago in Harper’s by I. I. Rabi (I think) discussing the dawn of the atomic age. The one thing I remember from that article was where he said that all the physics professors at the university of Hungary (I think it was) - which many of the atomic pioneers attended - knew all the contemporary physics, and knew the whole atomic business was all wrong - so that Rabi and his young peers had to stop attending classes and start from scratch educating themselves. That’s a classic example of where paradigm revolutions are hindered rather than helped by traditional wisdom.

Best,

It sounds to me as if you fear not that it might fail, but that it might succeed.

You’ve always said you’re open to any new ideas. So why this energetic attempt to get us to drop the economic modeling effort? I won’t try to guess, but it’s a question that needs an answer.
Please, of all people, why are you speculating about my higher level reasons for my adamant behavior against spending time on your proposed model. And, you even imply a hidden agenda. I have been very clear about my reason. I think it is a waste of time. But, if you want to pursue it, I wish you well.

I have spent a reasonable amount of time studying how a capitalistic economic system works. I have even tested various aspects of how people can contribute to better and superior results working within that system, the real system; not in a contrived model of it. I even have data on the results. They are very encouraging to me and those who have achieved them. To suggest that I, or anyone, needs your proposed model to figure out how the system works is absurd.

Your wonderful theory of human behavior, and the models you have created to explain why people do what they do, have been a treasure to me. But, the vast majority of people who study human behavior have ignored your theory and your model. Even if you were to come up with a more accurate model of an economic system, what makes you think you will have any more impact than you have had in psychology?

So, I think you are chasing the wind. If it is the best use of your time that you can come up with, so be it. Produce something new and I will evaluate it. I am all for acquiring better knowledge and methods to achieve better ends. I am an engineer at heart. Some of the brightest PCTers on this Net not only were schooled in the previous theories

KK: To start some thinking about this premise, I will raise just five points for now:
is the economic system a closed-loop system?  Was not the USA depression, or its steady rise to the most prosperous nation in the world in less than a century proof of an open-loop system?

BP: No, it was not, any more than the occurrence of periodic wars shows they are signs of open-loop systems. Those were consequences of how the people in the USA and elsewhere interacted with each other. And people are control systems, not open-loop systems.
Oh, I agree people are closed control systems. I don’t agree that economic systems behave only as closed loop control systems. One reason is that not every element of the economy is the result of human action. In fact, the hurricanes that hit New Orleans, overwhelmed its economy regardless of what humans did. It was an open loop phenomena in the economic system in my view. But, offer your perception and how such non-human factors will be incorporated in your model.

KK: is the elemental basis for an economy what producer people and consumer people do?  Or, since the economy of a nation is always measured in monetary units, is it more sensible to start with people who make financial transactions, generally called buyers and sellers?

BP: Definitely it is what buyers, sellers, producers, and consumers of goods and services do. These are all living human control systems and everything that happens in economies happens only because of what these people want and perceive and do. An economy is not some mysterious machine operated by invisible rules or jerked around by some invisible puppeteer. We have met the economy and it is us. It is what people do as they try to control what happens to them. The economy is just one special case of human behavior.
Saying it is one thing. Trying to model what buyers and sellers do takes a theory. Just observing the difficulty in defining what money is, or how prices get established or why on this Net, suggests to me that you are unlikely to discover a theory that everyone can accept, especially with those darn experts that have competing theories they have discovered.

Oh, the economy is a mysterious system that even weather affects in ways that are unknown and unknowable to humans with or without an historically accurate model! It has invisible and unwritten and unmeasurable rules not created by humans. It is like the origin of the universe or how it works…mysterious.

The Hubble exposes past scientific explanations as bogus and leaves scientists scratching their heads and disagreeing on new speculations of what they observe. But, hey, something so much easier as modeling what seven billion people do or don’t do to change economic development, well that will be rather easy, or so you seem to think, and we can ignore the non-human-made and non-human-controllable properties. Good luck.

KK: is an inanimate economic system subject to the rules of PCT?

BP: There is no inanimate economic system. If you remove the people, there is no economy.
If there were no people, we would not need an economic model either. The rules, written and unwritten, of the inanimate economic system limit what people can and cannot do to achieve their goals. You have not created the economic system used in America and can’t even suggest who did, or who can change it, and what people will and will not do even if it changes by decree.

KIK:   Do people individually, or even collectively, control the economic system performance or does the economic system constrain and control what people want and can do?

BP: The people, individually and collectively, create and sustain the interactions we call economics. The people ARE the economic system; what they want and do is the engine that drives economics, and that totally determines the economic processes we observe.
I have already suggested that the weather can determine what we observe in the economic process regardless of what people in the system do. A nuclear attack by an external enemy will also cause economic interactions beyond the control of the Americans. People are people; they are not an economic system. This sounds wise, and may well be a missing element in most economic theories. So, again, when you quit talkin and start chalkin, me and many others will consider your findings. People will control for many things other than an economic system producing at best some side effects.

KK: if we want someone to build a model of a system, would we want that someone to be a novice or someone who has worked tirelessly to know all there is to know about the real system and how it has performed historically?  Would we ask a entomologist to make a model of our country's human health care system?

BP: I would greatly prefer an open-minded novice who understands modeling to create the model, rather than someone who has built up a store of prejudices and incorrect rules of thumb because of not having a proper model and therefore not understanding what is really going on. Would you rather have an effort to model human behavior run by 100 behaviorists with 50 years each of experience studying behavior, or a naive engineer who happens to know about control theory?
I would rather have 100 behaviorists create and apply the model to test their understanding of human behavior. Then, they might reorganize. They won’t because an engineer finds a more satisfying theory. Over 35 years seems to prove that. Will poking your finger at economists and how stupid they are produce any greater change in accepted theory than what that has happened with classic psychologists?

At least folks like Rick and Dick and David had a knowledge of and practiced the old psychology theory that might influence classic psychologists to reconsider their own dogma. They are more effective witnesses of better behavior theory than auto mechanics. But, you have no credibility with economists. I believe that will hamper the acceptance of any economic discoveries you claim your model reveals. Again, if you perceive making an economic model is the best use of your time, who am I to say you should not? I guess I am just hoping to share some perspective that might influence you to deal more with behavior issues, than economic issues.

KK: is there anyone who believes that a country’s economy is an independent variable? Or, is it obvious that different economic systems in many nations work differently and affect the economic system performance in any one country?

BP: I don’t care what anyone believes; they can and do believe anything imaginable. I care about what they can demonstrate to be true. An economy consists of all the dependent variables that people control, all the reference conditions that specify how they want those variables to be, all the physical laws that connect actions to their consequences, and all the biological laws that enable human beings to exist and work as they do. All economic systems, however different they may appear, work because of these elements of human behavior. The differences arise from differences in goals, perceptions, and available means of control, not because the dirt inside the boundaries of Albania contains an Albanian economic system and so on country by country.
You have been to China. Do you not care what they believe and do in their economic system? Are you interested in how they are doing? Are you interested in how the economy is doing in Pittsburgh? Would such knowledge help you ensure your model includes their beliefs and actions? Note that their economic performance is relatively good and was achieved without the benefit of your hoped for educational model.

KK: The kind of person I would want to make a new economic model would be someone who is steeped in economic systems, their components and their historic performance.

BP: That would not give you a model; it would give you a defense of the most authoritative misconceptions that precede the first successful model. In 1491, the consensus among experts was that Columbus would sail right off the edge of the world into an abyss. When great increases in our understanding occur, inevitably it is the experts who are proven wrong, because they became expert in what was previously believed and, most probably, argued vehemently against the new understanding as it began to take shape. Therefore I would not turn the construction of a model of the economy over to people steeped in the old ways of thinking and who know only the history of economics – though I would consult them on matters of fact.
Columbus acted on the existing global system. He did not make a model first, or have to, to advance understanding. He conducted an experiment to test the understanding of the current system. I believe the same thing is true for the economic system. In this sense, Rick seems right. We know about actions taken to affect the system performance. We should be able to learn from those results. Unfortunately, data and correlations are so misunderstood that their conclusions are not trustworthy.

KK: Data is helpful but a working model to me would also have to include a theory of how the components of the economic system interact.  When you run the model, aren't you really testing the theory in the model to know whether it accurately duplicates what has been historically observed?

BP: Absolutely, that is precisely what we do in generating any working model. We make a guess as to how the model should be organized (how its components should interact), fill the model in with any imaginary properties it needs in order to run, and run it. Then we compare what the model did with what the real system did and look for all the differences we can find. We use historical data for this because predictions would be futile until we can at least make the model match what has already happened. That’s just standard practice in the physical sciences and engineering. That is exactly how I would organize the development of an economic model, and how I’ve already described the project, in case you missed it.
I am with you here Bill for most physical sytems. I just do not think you, even with some help from those who have learned what economic systems can and have done, can do it for a system that combines physical and human interactions by individuals or collectively within nations .

As we modify the model to eliminate the differences from real data, we begin to understand the real system better, and see where the basic organization of the model may need revision. So around and around we go, model, data, test, revise, model, data, test, revise … each time making the model more like the real system. This process can converge to some pretty good models. It gave us modern physics and chemistry.
If you have the time and knowledge to model the complex system of economics, go for it. Knowing how to create a model is valuable. Are tracking models the kind of knowhow that ensures understanding the public education system or the national economic system. I think it is a stretch and can easily fail. It is not sufficient to create an accurate model without including all the variables and their interactions that are part of the economic system. Producers and consumers? I doubt that will get you to first base. And, runs, not hits, are what will achieve a winning change in how economy policy should be set by those who can do that, whomever that is. Do you know who that is? Does the economy change effectively when those in authority change the economic system, or is it those people who act in the system that make the changes?

KK: Here are some simple questions about national economies that might reveal whether someone is aware of and steeped in how economic systems perform and work, and produce superior results than other systems and other nations.

BP: What’s this obsession with being superior to other systems and other nations? Who cares who we’re superior to? Is this some kind of king-of-the-hill contest? Don’t you know you’re well off without having someone much worse off to point to? I’d like to see everybody happy and satisfied, wouldn’t you? Isn’t it a little embarrassing to sit at the banquet table burping and picking your teeth while others watching you are starving? Or does that just make sitting at the banquet table seem even better? It makes me uncomfortable.
Looking at how different economic systems and policies perform relatively give us clues as to what variables and policies matter to desired results. To act like this is immaterial, and simply start with a clean sheet of paper to see how producers of pork bellies can find economic fulfillment by using their output to obtain an input of jewelry they desire, seems like an unnecessary regression. Starting from scratch seems to ignore one of our most valuable human abilities; the ability to learn from experience and from others.

KK: What nation has the largest economy in the world?  What has that nation done that makes its results so much more superior than even #2?

BP: From the adjectives you use, I would guess that that nation just wants to be better than everybody else. Is there something to admire in that?
Is there something to admire in not caring about what is possible? Is it better to be satisfied with the average? Should those below the average have a goal of becoming average? I make no condemnation of those who want to excel and achieve what has not been achieved before. Do you?

    1.   If we look at productivity per citizen rather than just size, what are the top 20 nations in GDP per citizen?  How do we explain the differences?
      
  1.   What nations have the largest markets for products and services?  What nation has the largest market for automobiles in 2009?  What role does market size play in an national economy versus the gross domestic product or production capacity of that country?
    
  2.   What measure of economic performance in a nation is the most vital in the quality of life experienced by its citizens?
    
    KK: What are the top ten largest economies in the world? What economic system do each of them use? Is there ranking primarily related to the economic system enforced in their country by the government or by the actions and efforts of its citizens?
    BP: Ah, the last one strikes a chord. Certainly it’s not the lavish riches we wallow in. I’d say that friendship and love, respect for other human beings, understanding human nature, appreciation of beauty and knowledge, and seeking new frontiers are among the top measures of quality of life. Having a lot of money without those things wouldn’t mean much. Being better than everybody else certainly isn’t among them. Neither is selfishnes or self-congratulation or self-importance or self-aggrandizement. Read the Bible – Jesus told us what matters. Consider the lilies of the field; they toil not nor do they spin, yet they are just as important in the human economy as the highest priest or the Roman emperor. A rich man has about as much chance of getting into Heaven as a camel has of passing through the eye of a needle. I don’t know if Jesus was the son of God, I think not, but he was pretty far ahead of his time. It’s not surprising that he got in trouble with the Establishment – just about every Establishment there was at the time. Even his own people chose Barrabas.
    Thanks for quoting the Bible as if you think it might be relevant. But, aside from that and its author, here Bill we totally agree. It is why I think working on a model of the economy, or how to accumulate more money or wealth, is a waste of time. So, read your own words and stated beliefs. Why not use your knowledge and gifts to advance those human needs that are way more important than bank accounts and assets? I try to do that and the quality of my life has gotten better as I quit worrying about politics and economics in the USA.
I honestly don't know why we would expect someone with little practical knowledge of various economic systems, or their differences, or how they have performed relatively to do a valuable job of creating a model to explain the actual and prospective working of the economy in any given country.

Well, I’ve told you what I think.
And, I have too. Perhaps we just disagree. It would not be the first time. Yet, life and friendship has gone on and prevailed. You have made my life better. I wish I could do the same for you.

I long for a coherent explanation from Bill.  Perhaps I just don't get it?

Maybe you don’t. I don’t know – you’re there inside of you, and I’m out here. You have expressed your preferences pretty well in your post, and I’ve rejected most of them, so you should have a pretty good idea of what I get and don’t get, though you can’t know, either.

  If I wanted to create a model for the most sensible and economic way to produce and consume electrical power and energy, I would not seek the best chef in the country.  The smartest and most powerful financial economists in the world are right here in Pittsburgh this week.  Shouldn't they be guiding and funding development of a new economic model. 

Good God, NO! Aren’t you forgetting what these financial geniuses have just finished doing to us from behind? Those of them who weren’t the leaders in causing the crashes didn’t do a thing to stop the disasters because they had no more idea of how the system works than the janitor who cleans up after them has. All they have is a lot of superstitions and business-school mottos to back them up. Expand or die, yeah, sure. Indifference curves, oh boy. They know what to expect from each other, of course, which is why they don’t trust each other. I’m not saying they’re stupid; they’re just full of facts that ain’t so. There is no “law” of supply and demand. There are only people who want things and act however necessary to get them. But economists know nothing about people, so they try to formulate economic theories with no people in them. That’s why there is no economic model yet (apologies to the new agent-based economic theorists, who are trying to put the people back in).
There is a lot of truth in what you say. But, when I think of economic systems, I do think of what people can and could do to improve their quality of life as they define it with more economic resources. Perhaps it is to have a Lexus or Mercedes? Perhaps it is to pay the outrageous costs of a college education for their children or a lung transplant for their mother. I won’t count on our government to do either for me. Look how they run the post office if you buy that model for our economy.

I suspect that less than a percent of the money they are spending while in Pittsburgh would put a world-class model development team together that could devote all the time and resources necessary to get the best model possible in the least amount of time.  If a model really is possible and needed, would it not be obviously worthwhile to get the proposal defined and accepted for action?

It’s a lot of fun to exaggerate and I don’t apologize.
Your faith is touching but misguided. The vast knowledge you imagine doesn’t exist. It’s not that these guys don’t know anything: obviously they know an enormous amount. They just don’t know about the important and essential things, such as people being control systems. And I’ll bet there isn’t one of them that knows how to construct and test a model (do you?). Without that missing knowledge, the rest of what they know is useless.
As I previously said, I do not need a model to conduct a scientific experiment on the real economy of businesses who provide economic power and control for employees who find that valuable. Yes, I have constructed models and collected data to see if they fit. I call it the Defective Work Model. It helps people understand their quality control system and how to improve performance. If I really thought I could model the economic system in the USA, I would join your effort. I am skeptical and will not apologize for that. If you know know enough to make it happen, I will praise you and eat some crow.

What is the restraint?  Why would that be resisted as a disturbance to what reference perception?

Very simple: I don’t agree with your assessment of the abilities of these people. I don’t think they know how to construct a model. I don’t think that much of what they know is true. I don’t think they know how people work.
We are close in perception here. But, knowing how people work is not the only thing necessary to know what kind of economic system works best. I think that is at the heart of our difference?

  I wish I knew but about all I can do is guess.  I can guess about chasing the wind and hope I might discover an accurate model of where it comes from or where it goes, but there seems to be more worthwhile ways to spend my time.

I can agree with that. I take it that you’re not volunteering your services to the model-building team. Go play tennis with David.
You perceive that one correctly. David and I play tennis with each other a few hours a year. It satisfies some higher level references for how we spend our time. The rest of the year, David and I try to use our time and knowledge to help people achieve their stated goals. Helping you achieve your economic model goal is not one for me. To my knowledge David uses his time for other purposes more meaningful to him too. I think we both agree that your PCT knowledge and models have been helpful to us. Perhaps your economics model will be too, but that is not obvious to us at this time as a goal we do not know how to satisfy or one that needs attention.

I really love you, Kenny, but sometimes you can be a pain in the neck. Well, so can I.

Best,

Bill P.
I love you too Bill and that won’t change whether or not you create an economic model based on human behavior. You are seldom a pain in my neck. You are a blessing and humble about it besides. I wish I could say the same for the Republican/Democrat rants by Rick or his rants against professed economists or believers in the Bible. If there is a state that needs his help, Calliefornia provides a great opportunity. I wish he would get busy there with his theories on politics, ethics and economics instead of on CSGNet. I really do not need his perceptions on the economy to improve the quality of my life. It would be like chasing the wind for me.

I remember an article, many years ago in Harper’s by I. I. Rabi (I think) discussing the dawn of the atomic age. The one thing I remember from that article was where he said that all the physics professors at the university of Hungary (I think it was) - which many of the atomic pioneers attended - knew all the contemporary physics, and knew the whole atomic business was all wrong - so that Rabi and his young peers had to stop attending classes and start from scratch educating themselves. That’s a classic example of where paradigm revolutions are hindered rather than helped by traditional wisdom.

Interesting questions. i would like to comment on just one. Near the end you said

[From Rick Marken (2009.09.24.1450)]

Fred Nickols (2009.09.24.1144 EST)--

No disrespect intended, Kenny, but you're starting to sound like a guy who
suddenly realized that a great deal of what goes on in the world is pure B.S
Your mayor is taking credit for a figure that might not even be correct. �But
he's a politician and that's what politicians do. �Surely, you don't expect them
to operate on the basis of data? �I don't and I don't want them to. �Why?
�Because good data are terribly difficult to come by and most of what's out
there is the result of cooking the books in one form or another, much of it
"cooked" by supposedly respectable researchers.

I think what's going on here is that data are being dismissed as
useless when they don't seem to agree with one's preconceptions and
pointed to as authoritative when they do. The Pittsburgh unemployment
data doesn't fit Kenny's assumptions about what should result from the
policies of a "Democrat" mayor but he points with glee to the fact
that the US has one of the highest per capita GDPs of any nation.
Kenny comes up with all kinds of reasonable reasons why the low
unemployment rate may be misleading but doesn't bother mentioning that
the high US per capita GDP is also misleading (since the distribution
of wealth in the US is highly skewed, per capita GDP overestimates by
a wide margin what the "typical" American is worth).

I would say that this kind of thing is seen only in right wing
ideologues but the fact is that the same thing happened in our recent
discussion of taxation and growth. Bill Powers dismissed as "useless"
the economic data I presented, ostensibly because the correlations
don't allow accurate prediction (never mind that that was my point)
but accepted without question the data showing a correlation between
age and some measure of hierarchical control that was not even
defined.

I think data are a very important basis for decision making when we
don't have a good model. But we also have to know how to carefully
evaluate the data before coming to conclusions about what it means. I
don' believe any data are "useless"; you can always learn something by
looking at the data, even if it is only that the data are misleading.
When someone says that data are "useless" I think you can count on the
fact that they will point to data as being very "useful" if it seems
to be generally consistent with their formal or informal
preconceptions.

Best regards

Rick

PS I can’t help but wonder if you have considered modeling human beings, to understand better how they work and what the real reorganization system in them is. I think that would be very useful in advancing the cause of PCT. I don’t think fussing with an economic model will do that.

Kenny Kitzke (2009.09.24.1200EDT)

···

KK: I have spent a
reasonable amount of time studying how a capitalistic economic system
works. I have even tested various aspects of how people can
contribute to better and superior results working within that system, the
real system; not in a contrived model of it. I even have data on
the results. They are very encouraging to me and those who have
achieved them. To suggest that I, or anyone, needs your proposed
model to figure out how the system works is absurd.

BP: Now we get down the the nitty gritty. To suggest that anyone needs to
study how the economy works (by any means) is absurd, because if we want
to know how it works, all we have to do is ask Kenny Kitzky.

KK: Your wonderful theory of
human behavior, and the models you have created to explain why people do
what they do, have been a treasure to me. But, the vast majority of
people who study human behavior have ignored your theory and your
model. Even if you were to come up with a more accurate model of an
economic system, what makes you think you will have any more impact than
you have had in psychology?

BP: Not a thing, Kenny, not thing. Many people in the psychological
sciences have looked upon my model of human behavior and feel that for
anyone to suggest that they, or anyone, needs that proposed model to
figure out how people work is absurd. You expressed that very well, so I
borrow your words. I think this is probably a fairly widespread human
attitude. People who have spent a lot of time dealing with some aspect of
life like to feel that they have been as successful at it as anyone could
possibly be, and they really don’t want to hear anyone say they could
have been doing it better, or –

God forbid – that they were entirely on the wrong track. Proposing that
we study something in a more effective way implies that there might be
some tiny little flaw in what is thought about that subject now, a
concept that might undermine our confidence if we let ourselves dwell on
it.

Also, people who have found successful ways of dealing with some aspect
of the world tend not to know (or care) much about the side-effects of
their actions on other parts of the world. The clever knowledgable people
who put together those packages of investments a couple of years ago were
highly successful at improving the profitability of the companies they
worked for, but they failed to see the consequences they were setting
into motion. Those consequences put their companies out of business or
under the control of taxpayers. Surpriiise!

KK: So, I think you are chasing
the wind. If it is the best use of your time that you can come up
with, so be it. Produce something new and I will evaluate it.
I am all for acquiring better knowledge and methods to achieve better
ends. I am an engineer at heart. Some of the brightest PCTers
on this Net not only were schooled in the previous
theories

Something must have distracted you there, but I get the idea. You’re all
for better knowledge and methods, only not where there is no need for
them, as in improving our understanding of the economy, and especially
yours. I know my understanding of it could use a lot of improvement, so
perhaps this project is really intended just for me and other ignorant
people like me. I think there may still be a few people interested in
this project, so I won’t give up on it right away. After it’s done, you
can tell us if we got it right.

I have to comment that I actually have read a bit of what leading figures
in economics have proposed as explanations. I can’t make any sense of
them – they aren’t the sort of explanations I’m used to, explanations
that actually explain something.

Oh, I agree people are closed
control systems. I don’t agree that economic systems behave only as
closed loop control systems. One reason is that not every element
of the economy is the result of human action. In fact, the
hurricanes that hit New Orleans, overwhelmed its economy regardless of
what humans did. It was an open loop phenomena in the economic
system in my view. But, offer your perception and how such
non-human factors will be incorporated in your model.

You’re confusing understanding a system with anticipating everything that
can happen to it from outside. One point of a model is to let you predict
the effect of unexpected events. If a majority of companies start
outsourcing their manufacturing needs, what will the effect on the
American economy be? We can’t predict what fads will appear within
management personnel, but we at least can learn how to predict what the
consequences will be. Maybe if the consequences can be predicted with
sufficient reliability, managers will learn not to pursue strategies that
are almost certain to end in disaster if they become popular. I think
most business managers like to think they understand how the economic
system works. They are obviously mistaken; what they understand, maybe,
is how one little part of it works. But that little part is embedded in a
much larger system, and the side-effects are going to generate resistance
and countermeasures. Would managers do the same things if they could see
ahead of time what the consequences in the larger system will
be?

KK: is the elemental basis for
an economy what producer people and consumer people do? Or, since
the economy of a nation is always measured in monetary units, is it more
sensible to start with people who make financial transactions, generally
called buyers and sellers?
BP: Definitely it is what buyers, sellers, producers, and consumers
of goods and services do. These are all living human control systems and
everything that happens in economies happens only because of what these
people want and perceive and do. An economy is not some mysterious
machine operated by invisible rules or jerked around by some invisible
puppeteer. We have met the economy and it is us. It is what people do as
they try to control what happens to them. The economy is just one special
case of human behavior.

Saying it is one thing. Trying to model what buyers and
sellers do takes a theory. Just observing the difficulty in
defining what money is, or how prices get established or why on this Net,
suggests to me that you are unlikely to discover a theory that everyone
can accept, especially with those darn experts that have competing
theories they have discovered.

Of course it takes a theory: what do you think a model is? It’s a theory
expressed as a working simulation based on the theory. The model, the
simulation, shows you what your theory actually implies, as opposed to
the few implications you were focused on because the were the ones you
like. With a model, we could test the theory that “supply creates
its own demand,” or Say’s Law. I know what Keynes and others have
imagined that the consequences would be if people really worked like
this, but I’d like to see for myself if they were right. I think they
were dead wrong. If the model says they were right I’ll believe it, but I
won’t believe it just because someone else keeps saying it’s
right.

The difficulty in defining money has come from the confused picture of it
presented by economists, particular those who have a vested interest in
the status quo and use their reasoning power mostly to try to prove it is
the best of all possible worlds. Treating price changes as something that
just happens is a handy way to absolve from responsibility those who
manipulate prices to achieve their purposes, not all of which they would
like others to understand better.

Oh, the economy is a mysterious
system that even weather affects in ways that are unknown and unknowable
to humans with or without an historically accurate model! It has
invisible and unwritten and unmeasurable rules not created by
humans. It is like the origin of the universe or how it
works…mysterious.

BP: OK, you’ve given up. I haven’t.

BP earlier: There is no
inanimate economic system. If you remove the people, there is no
economy.
KK: here were no people, we would not need an
economic model either. The rules, written and unwritten, of the
inanimate economic system limit what people can and cannot do to achieve
their goals. You have not created the economic system used in
America and can’t even suggest who did, or who can change it, and what
people will and will not do even if it changes by
decree.

BP: OK, OK, you don’t understand these things and don’t even want to try,
and you have every right to make that decision for yourself. But you
don’t have any right to make it for me or anybody else. The risk you take
is that someone else will actually try to understand these things, and
even worse, may succeed. That would leave you looking a bit foolish,
wouldn’t it? The person who tries and fails has nothing to be ashamed of,
but what of the person who can only hope that everyone else who tries
will fail? I’d be ashamed of doing that. And is there anything wrong with
trying to understand everything, and ending up only understanding a
little more of some of it?

There’s more in this post, but there’s nothing further new in it to
discuss.

BP: In your comments on my essay (which essay could stand some
revision), you stated your position in all its confused glory:

KK: Show me the money! Show me what variables and
relationships predicted the performance of the economic system say even
in the last eight years.

BP: You can’t really expect me to do both things: stop wasting my
time proposing that we develop a working model of the economy, AND use
that finished model to show you the variables and relationships that
would predict the performance of the economic system. How can I show you
what the model says before the model exists? How could the model exist if
I’m not supposed even to start developing it?

KK: PS I can’t help but wonder
if you have considered modeling human beings, to understand better how
they work and what the real reorganization system in them is. I
think that would be very useful in advancing the cause of PCT. I
don’t think fussing with an economic model will do
that.

BP: Boy, you really, really don’t want me to work on that
economic model! “Stick to PCT and KEEP YOUR NOSE OUT OF
ECONOMICS!” Don’t you see that any model I produced would be
organized around human control systems and my theory of how they work?
And that the model of “economic man” that economists believe in
is entirely wrong if PCT is right? It’s hard for me to see how you could
claim to admire both the theories of economics that you have learned
about AND the theory that people are living hierarchies of control
systems who try to make their inputs match internally set reference
levels. PCT is entirely incompatible with the way economists think people
work. You can’t believe in both approaches unless you have a different
brain to use in thinking about each of them. If economic theories are
right, Bill Powers’ theory is wrong. And vice versa. You can’t make them
both be right at the same time. You have to choose.
This is called a conflict, Kenny. You know, those things you help
other people to resolve?

I have a strong suspicion that this type of conflict is the reason why many people have left CSGNet and blamed their leaving on me. The conflict is always between admiring Bill Powers’ theory (PCT) and admiring some other theory which is wrong if Bill Powers’ theory is right.

As long as the inconsistency between PCT and the “theory not compatible with PCT” never comes up there is no problem; the person can control for believing in the two incompatible theories without experiencing any error. But when there is a disturbance, there is a big reaction for the conflicted individual. Usually the reaction is to get mad at me because I am usually happy to keep discussing how particular theories are incompatible with PCT. Even if the disturbance to the “theory not compatible with PCT” is created by Bill Powers the tendency is to blame the problem on me because Bill himself is always part of the conflict; pushing back against Bill’s disturbance to an"theory not compatible with PCT" just increases the error in the person who is controlling for the “theory not compatible with PCT” as well as his admiration of Bill.

So blaming the problem on me is generally a good strategy for “solving” the conflict, in the sense that by removing the disturbance to one side of the conflict (me) the conflict at least won’t express itself. This strategy works particularly well when Bill, for whatever reason, tries to smooth over the conflict by finding fault with something I said or the way I said it. But there is a real problem for the person with the conflict when Bill himself will not stop being the disturbance, as is the case here with the economic modeling. It will be interesting to see how this ends.

And that the model of “economic man” that economists believe
in
is entirely wrong if PCT is right? It’s hard for me to see how you

There’s another possibility, or possibilities, no?

  1. Economic theories are wrong at their foundation, but usually give as
    right an answer as a correctly founded theory could do for the
    variables that are easily measured (as did the phlogiston theory of
    heat, for a while), given the complexity of interactions and the
    considerable influence that can occur from natural and human events (a
    bad breakfast influencing a critical decision, for example). That would
    make both Kenny and Bill correct.
  2. PCT-economic man may need to be modelled in a more complex way than
    is feasible with existing computational resources before a plausible
    (agreeing with post-dicted data) model can be produced. In this case,
    one would never know whether Bill or Kenny is right.
  3. In neural network theory, good results for complex systems are
    sometimes achieved using “mean-field theory”, by which the effects of
    many neurons interlinked in complex ways are treated as though they
    were one big uniform chunk. That’s Rick’s approach to modelling
    economic systems. The underlying concept may be PCT, but the modelling
    does not require it. If that works, it would be irrelevant whether Bill
    of Kenny was right, but it would leave an opening for Bill’s modelling

If you wish to impugn, or even guess at my motives, based on what I write, please use what I wrote. I did not say “To suggest that anyone needs to study how the economy works (by any means) is absurd, because if we want to know how it works, all we have to do is ask Kenny Kitzky.”

Does it disturb you that clients do ask me how they can manage their business? Does it surprise you that one client that retained me for a dozen years set record sales and earnings for thirteen straight years which was not true of their performance in the five years before they tried some new ways to create greater value for their stakeholders, including their employees? And, they did this without the benefit of a new economic model. Oh, it might have been luck.

Speaking of nitty gritty, let’s get down to yours regarding your envisioned economics model:

BP: I don’t care what anyone believes; they can and do believe anything imaginable. I care about what they can demonstrate to be true.

Do you mean demonstrate by actual results to be true? Does audited 13 years of growth in sales, with profits growing faster than sales, qualify as a truthful demonstration. Perhaps that company knows something worthwhile? Perhaps if the economic ministers or you would investigate what they believe and the results their implemented beliefs did for the economy of their business and the economy of their employees. Nah, how could they know how an economy works until you finish your model?

Kenny Kitzke (2009.09.24.1200EDT) –

BP: Now we get down the the nitty gritty. To suggest that anyone needs to study how the economy works (by any means) is absurd, because if we want to know how it works, all we have to do is ask Kenny Kitzky.

BP: Not a thing, Kenny, not thing.
Then why are you so adamant on creating a new model of an economic system? Can you go up a level or two for me?

Many people in the psychological sciences have looked upon my model of human behavior and feel that for anyone to suggest that they, or anyone, needs that proposed model to figure out how people work is absurd. You expressed that very well, so I borrow your words. I think this is probably a fairly widespread human attitude.
Do you suppose it applies to me? How about to you and an expressed need for a new economic model?

People who have spent a lot of time dealing with some aspect of life like to feel that they have been as successful at it as anyone could possibly be, and they really don’t want to hear anyone say they could have been doing it better, or –
God forbid – that they were entirely on the wrong track. Proposing that we study something in a more effective way implies that there might be some tiny little flaw in what is thought about that subject now, a concept that might undermine our confidence if we let ourselves dwell on it.

Also, people who have found successful ways of dealing with some aspect of the world tend not to know (or care) much about the side-effects of their actions on other parts of the world.
Here comes the straw man. Your knowledge of HPCT has revealed this to you?

The clever knowledgable people who put together those packages of investments a couple of years ago were highly successful at improving the profitability of the companies they worked for, but they failed to see the consequences they were setting into motion. Those consequences put their companies out of business or under the control of taxpayers. Surpriiise!
A few have gone to jail, but most laughed all the way to the bank. They are no heroes to me. They disgust me. But, not all business people do what they did, do they? Do you even know for sure whether they are the exception or the rule? Do you have any data or just impressions? Flinging around generalizations is something you usually resist. People are different and so are companies, right?

KK: So, I think you are chasing the wind.  If it is the best use of your time that you can come up with, so be it.  Produce something new and I will evaluate it.  I am all for acquiring better knowledge and methods to achieve better ends.  I am an engineer at heart.  Some of the brightest PCTers on this Net not only were schooled in the previous theories

Something must have distracted you there, but I get the idea. You’re all for better knowledge and methods, only not where there is no need for them, as in improving our understanding of the economy, and especially yours. I know my understanding of it could use a lot of improvement, so perhaps this project is really intended just for me and other ignorant people like me. I think there may still be a few people interested in this project, so I won’t give up on it right away. After it’s done, you can tell us if we got it right.
Deal! I acknowledge that you know more about human behavior than me because you understand PCT/HPCT better than me. I don’t resent you for that. I don’t consider myself ignorant because of it. I don’t think you perceive me as ignorant because of this fact. Could it be possible that Kenny understands more about economic systems and how they work than you do? Would that make you ignorant? Of course not. I believe I do know more about the American and world economy and how they work than you do. So, prove me wrong.

I have to comment that I actually have read a bit of what leading figures in economics have proposed as explanations. I can’t make any sense of them – they aren’t the sort of explanations I’m used to, explanations that actually explain something.
I have perceived some of them likewise. Take Christina Romer, economic advisor to Obama. Please take her and put her back in the university. She makes me sick. She and her husband Roger actually believe that, “At the same time that Obama is calling for higher income taxes on people making $250,000 or more, the Romers have found that tax increases are generally bad for economic growth and that they primarily discourage investment – the supply-side argument that conservatives use to justify tax cuts for the rich.” Obama’s Inner Circle

Rick, read it and weep.

Oh, I agree people are closed control systems.  I don't agree that economic systems behave only as closed loop control systems.  One reason is that not every element of the economy is the result of human action.  In fact, the hurricanes that hit New Orleans, overwhelmed its economy regardless of what humans did.  It was an open loop phenomena in the economic system in my view.  But, offer your perception and how such non-human factors will be incorporated in your model.

You’re confusing understanding a system with anticipating everything that can happen to it from outside.
The weather in the USA is not external to the USA economic system. I am not sure you understand what an economic system is. Rain is a critical factor in the means of food production. Oh, it can’t be, people are the system. I just forgot, silly me. They will grow produce and crops regardless, if they want to.

One point of a model is to let you predict the effect of unexpected events. If a majority of companies start outsourcing their manufacturing needs, what will the effect on the American economy be? We can’t predict what fads will appear within management personnel, but we at least can learn how to predict what the consequences will be. Maybe if the consequences can be predicted with sufficient reliability, managers will learn not to pursue strategies that are almost certain to end in disaster if they become popular. I think most business managers like to think they understand how the economic system works. They are obviously mistaken; what they understand, maybe, is how one little part of it works. But that little part is embedded in a much larger system, and the side-effects are going to generate resistance and countermeasures. Would managers do the same things if they could see ahead of time what the consequences in the larger system will be?
I don’t know, do you? How could you know what others will do under unexpected conditions? How are you going to model the variables in the larger system and how they always and accurately effect the smaller system?

    KK: is the elemental basis for an economy what producer people and consumer people do?  Or, since the economy of a nation is always measured in monetary units, is it more sensible to start with people who make financial transactions, generally called buyers and sellers?
BP: Definitely it is what buyers, sellers, producers, and consumers of goods and services do. These are all living human control systems and everything that happens in economies happens only because of what these people want and perceive and do. An economy is not some mysterious machine operated by invisible rules or jerked around by some invisible puppeteer. We have met the economy and it is us. It is what people do as they try to control what happens to them. The economy is just one special case of human behavior.
Saying it is one thing.  Trying to model what buyers and sellers do takes a theory.  Just observing the difficulty in defining what money is, or how prices get established or why on this Net, suggests to me that you are unlikely to discover a theory that everyone can accept, especially with those darn experts that have competing theories they have discovered.

Of course it takes a theory: what do you think a model is? It’s a theory expressed as a working simulation based on the theory.
What is the source of the theory you will place in your model?

The model, the simulation, shows you what your theory actually implies, as opposed to the few implications you were focused on because the were the ones you like. With a model, we could test the theory that “supply creates its own demand,” or Say’s Law. I know what Keynes and others have imagined that the consequences would be if people really worked like this, but I’d like to see for myself if they were right. I think they were dead wrong. If the model says they were right I’ll believe it, but I won’t believe it just because someone else keeps saying it’s right.
Amen. When you have the model working, we will all take a look.

The difficulty in defining money has come from the confused picture of it presented by economists, particular those who have a vested interest in the status quo and use their reasoning power mostly to try to prove it is the best of all possible worlds. Treating price changes as something that just happens is a handy way to absolve from responsibility those who manipulate prices to achieve their purposes, not all of which they would like others to understand better.
Oh, those price manipulators do drive us nuts. Were you thinking of OPEC?

Oh, the economy is a mysterious system that even weather affects in ways that are unknown and unknowable to humans with or without an historically accurate model!  It has invisible and unwritten and unmeasurable rules not created by humans.  It is like the origin of the universe or how it works...mysterious.

BP: OK, you’ve given up. I haven’t.
I have given up on making the kind of model you desire. I have not given up on knowing more about how economic systems work by analysis.

  BP earlier: There is no inanimate economic system. If you remove the people, there is no economy.
KK: here were no people, we would not need an economic model either.  The rules, written and unwritten, of the inanimate economic system limit what people can and cannot do to achieve their goals.  You have not created the economic system used in America and can't even suggest who did, or who can change it, and what people will and will not do even if it changes by decree.

BP: OK, OK, you don’t understand these things and don’t even want to try, and you have every right to make that decision for yourself. But you don’t have any right to make it for me or anybody else.
Golly, did I imply I did? I just think it is like chasing the wind. Prove me wrong. I am all ears.

The risk you take is that someone else will actually try to understand these things, and even worse, may succeed. That would leave you looking a bit foolish, wouldn’t it? The person who tries and fails has nothing to be ashamed of, but what of the person who can only hope that everyone else who tries will fail? I’d be ashamed of doing that.
Last time I thought about it, I am not ashamed of doing something I find worthwhile and not supporting things I see as low-probability of success activities.

And is there anything wrong with trying to understand everything, and ending up only understanding a little more of some of it?
Is there anything wrong with a goal of understanding our economic system better by a different means than by trying to evolve a working model? I thought that was a premise of PCT; achieving a goal by varying and various means. It seems unapologetically human to me.

There’s more in this post, but there’s nothing further new in it to discuss.

Best,

Bill P.

So you say, my friend.

Bill, there is no Catch 22 here. I know the model doesn’t exist now. But, you claim one can be constructed over time. When that is done, I will weigh what you have discovered against the real system. But, honestly, I don’t think either of us will be alive that long.

That may be but are you confused that I think the way economists think? My thinking is upside-down from theirs! I view the economic summit (I just watched Obama’s conclusions) as a cruel charade, much like Fred does as largely a self-aggrandizing show sprinkled with BS nonsense. But, that does not mean they do not understand financial terms or have not tried to figure out how economic systems work best. All their experiences are probably a bit different. And, my guess is that economics is as much a politically created system as one created by individual producers and consumers.

You can’t believe in both approaches unless you have a different brain to use in thinking about each of them. If economic theories are right, Bill Powers’ theory is wrong. And vice versa. You can’t make them both be right at the same time. You have to choose.
Whoops. Can they both be WRONG? What if it turns out that only Kenny’s economic system is accurate. Yep, that would be a surprise.

Conflict can lead to learning. It does not have to be nasty. One or both of us may reorganize as to what constitutes a workable and goal attaining economic system and stay friends! I won’t use Rick’s approach and call those who disagree with me a_ _ holes.

Powers’ theory is wrong. And vice versa. You can’t make them both be

MT: There’s another possibility, or possibilities, no?

  1. Economic theories are wrong at their foundation, but usually give as
    right an answer as a correctly founded theory could do for the variables
    that are easily measured

BP: As far as I have experienced the “right answers” in
economic theory, when economic theories disagree with the data,
economists explain that data are unreliable, whereas their theoretic
concepts are self-evidently correct. So they don’t actually know if their
answers are correct. They just assume they are. The idea that supply
creates its own demand is deemed correct, while the fact that people do
not simply accumulate as much goods and services as they can is ignored
becaue it’s misleading, and anyway marginal utility explains it.
Economists prior to agent-based economics have not tested their models by
putting them in the form of simulations and running them, which of course
would immediately show what is wrong with this idea about demand. Maybe
some have, but I haven’t heard of any.

MT: (as did the phlogiston
theory of heat, for a while), given the complexity of interactions and
the considerable influence that can occur from natural and human events
(a bad breakfast influencing a critical decision, for example). That
would make both Kenny and Bill correct.

BP: But your assumption on which this conclusion rests is false, as far
as I know. The truthfulness of economic theories is unknown. They use
them mainly to explain what has already happened, but they don’t often
risk using them to predict what will happen next.

MT: 2. PCT-economic man may need
to be modelled in a more complex way than is feasible with existing
computational resources before a plausible (agreeing with post-dicted
data) model can be produced. In this case, one would never know whether
Bill or Kenny is right.

BP: That’s simply not true. There is nothing in the PCT concept of
economic man that is different from the PCT concept of any sort of man.
The PCT model of economics that I have in mind is simply the same model I
apply to all human activities (yes, I know about hammers and nails). I
wouldn’t venture to include in the model what kinds of things or how much
of them people want, or what people’s motives are for particular
activities. I include places in the model where those things can be
specified to see what the consequences will be, but those are inputs to
the model, not built-in values.

My models of behavior that you have seen do not attempt to predict when a
person will be overcome with an irresistable urge to track a target or
control the shape of a ball on a computer screen, or the degree of skill
with which any individual will do the tracking, or whether a person will
follow the directions. Those models simply enable us to see what happens
when a person does try to track a target or stabilize the ball’s shape,
and to derive the values of assumed system parameters from past data and
use them to predict performance in similar tasks with somewhat different
conditions (for example, different patterns and numbers of disturbances).
We can even deduce, within limits, whether the person correctly followed
the directions, and if not, again within limits, what the person was
actually trying to do. This is how we come to understand human behavior
in these special situations.

In a model of economic man, the independent variables that we (or anyone)
can set at will are things like reference conditions and disturbances,
and changes in environmental properties. We can even change the embedded
theory of economic man, substituting for the control systems assumed in
PCT models a model in which, for example, a person simply produces output
enough to obtain as much of a good as possible as long as the money holds
out. The model will then (when it is all finished and checked out) show
what will happen if all agents in the model behave that way. That is not
how economic models have been constructed or tested in the past, as far
as I know.

MT: 3. In neural network theory,
good results for complex systems are sometimes achieved using
“mean-field theory”, by which the effects of many neurons
interlinked in complex ways are treated as though they were one big
uniform chunk. That’s Rick’s approach to modelling economic systems. The
underlying concept may be PCT, but the modelling does not require it. If
that works, it would be irrelevant whether Bill of Kenny was right, but
it would leave an opening for Bill’s modelling to try to fit a valid
foundation under Rick’s working “mean-field”
model.

BP: We already do exactly the same thing in PCT. I use a
“mean-field” definition of the input and output functions in a
control model, not attempting to guess how the overall effect is achieved
but simply assuming that there is some signal inside that corresponds to
what we external observers see going on. When one doesn’t know the
details, one can’t model them.
Rick assumes a virtual control system for governing GDP, whereas I want
to leave GDP as a dependent but not controlled variable. As with
Lovelock’s concept of Gaia as a global control (well, equilibrium)
system, it’s possible that we are seeing a composite system made of many
individual control systems, but before I can go along with that I would
need some evidence that GDP is protected against disturbances by some
mean activity that depends on departures of GDP from its composite
reference level. I haven’t seen any evidence of that. So it’s not a
question of slipping a model underneath Rick’s model; it’s simply a
question of applying the test for the controlled variable. If GDP proves
to be under control, I will have no reason to object to Rick’s model. If
someone can demonstrate that maximization of input will make the model
behave as real people do, I’ll pipe down about that, too.
PCT is not really the central aspect of the economic modeling that I’m
proposing. As I tried to make clear in my hasty paper on modeling
systems, modeling is more general than PCT – you can test any theory
using modeling, or simulation. If you think people are not control
systems but work in some other way, you can set up a model in which there
are rules of behavior appropriate to your theory, and see what it does –
show everybody what it does, instead of just making claims about
what it might do. It’s easy to draw a diagram and describe the system it
is supposed to represent, and describe the behavior of that system that
the model is meant to predict or explain. But proving that the diagrammed
system would, if simulated or even built, actually behave in the way
being claimed is an entirely different matter. Few people who present
diagrams of systems have any comprehension of what a physical system with
that organization would really do, as opposed to what they intended it to
do. And in the literature of many of the softer disciplines like
economics, they are never required to prove that their claims are
correct. How would Pribram’s famous TOTE unit actually behave if someone
tried to simulate it? I’m pretty sure that neither Pribram or anyone else
who cites that invention has tested it, because there are too many
situations in which it just wouldn’t work and I haven’t heard of any
reports of discovering that. Try it out with a tracking task.

Before we can use models of the economy to test various theories about
economic man, we have to agree on the basic mechanics of the model. We
have to agree on such things as the fact that when I buy something from
you, my bank account – my unused credit – decreases while yours
increases by the same amount at the same moment. And if physical goods
are involved, your inventory decreases at the same time mine increases by
the same amount. There are many, many such uncontroversial aspects of
economic transactions and other behavior that can be put into a model as
its foundation. That diagram I posted a week or so ago showed a row of
five control systems across the top, which you could give any properties
you want to test, or for which you could substitute any other kind of
agent you liked. But the part of the diagram below that showed flows of
money and goods between the producers and consumers that would be hard to
argue about, though it’s not by any means complete. That is the sort of
modeling I’m talking about: the aspects of the model we can agree on, or
test to see if we have it right. Anything at higher levels that we can’t
agree on can be added as a simulation interacting with the part of the
model we have agreed is correct, and we can then see what
happens.

If you look at that diagram, I think you will realize that the only parts
that would be controversial are those five control systems at the top –
the agents I have assumed, with their particular properties and goals.
All the stuff below is almost self-evident, or if someone objects to any
part of it we can argue it out and find out what we can agree on. I’m
saying that we need to develop the lower part of the diagram until it
covers as much economic territory as possible and until people with
different economic theories can agree on it. All theories will then be
tested by simulating them and connecting them to this basic foundational
test-bed which will correctly show the consequences of the agents’
behaving in different ways. I, of course, will be testing various
proposals for PCT models, but others can do the same with any models they
prefer. As is evident from looking at Rick’s proposals and mine, there is
more than one PCT model that could be tested. The only way to choose
among models is to plug them into the test-bed, and see how the
consequences of their behavior match up with what we actually observe.
Without that commonly-accepted foundational model, how could we ever
arrive at a consensus about which model works the best?

I know that this bottom-up strategy is very boring for some people, maybe
most people. But I don’t see any other way to compare different economic
theories, or to come to an unbiased conclusion about the consequences of
assuming any particular model of economic agents.

Best,

Bill P.

Shame on me. I should have realized that it just looked like people left CSGNet because of the abuse Rick laid on them: calling people who disagree with him a _ _ holes or ridiculing their deeply held religious beliefs. Here, all along, it was conflict these people created and then cleverly blamed it on Rick to find peace.

Oh, darn. I am in conflict now. Apparently I should leave CSGNet and blame it on Rick. But, I really want to stay and debate the data and the beliefs regarding an economic model and if it will be fruitful in solving economic problems in the real system. How will this end? Is life even worth living?

Pinch yourself Rick. I am still here.

It’s hard for me to see how you could claim to admire both the theories of economics that you have learned about AND the theory that people are living hierarchies of control systems who try to make their inputs match internally set reference levels. PCT is entirely incompatible with the way economists think people work. You can’t believe in both approaches unless you have a different brain to use in thinking about each of them. If economic theories are right, Bill Powers’ theory is wrong. And vice versa. You can’t make them both be right at the same time. You have to choose.
This is called a conflict, Kenny. You know, those things you help other people to resolve?

[From Rick Marken (2009.09.25.1115)]

I have a strong suspicion that this type of conflict is the reason why many people have left CSGNet and blamed their leaving on me. The conflict is always between admiring Bill Powers’ theory (PCT) and admiring some other theory which is wrong if Bill Powers’ theory is right.

As long as the inconsistency between PCT and the “theory not compatible with PCT” never comes up there is no problem; the person can control for believing in the two incompatible theories without experiencing any error. But when there is a disturbance, there is a big reaction for the conflicted individual. Usually the reaction is to get mad at me because I am usually happy to keep discussing how particular theories are incompatible with PCT. Even if the disturbance to the “theory not compatible with PCT” is created by Bill Powers the tendency is to blame the problem on me because Bill himself is always part of the conflict; pushing back against Bill’s disturbance to an"theory not compatible with PCT" just increases the error in the person who is controlling for the “theory not compatible with PCT” as well as his admiration of Bill.

So blaming the problem on me is generally a good strategy for “solving” the conflict, in the sense that by removing the disturbance to one side of the conflict (me) the conflict at least won’t express itself. This strategy works particularly well when Bill, for whatever reason, tries to smooth over the conflict by finding fault with something I said or the way I said it. But there is a real problem for the person with the conflict when Bill himself will not stop being the disturbance, as is the case here with the economic modeling. It will be interesting to see how this ends.

You may be right in your approach. I hope you are, but I suspect that you are an incorrigible optimist, and that the problem is of greater magnitude than the problem of weather prediction, where the issue is not the mechanistic (physico-chemical) structure of the problem, but the resolution of the data-gathering and of the computational space.

I meant what I said about the complexity of the interacting control systems within each "homo-economicus" being an issue in your modelling, since any dynamic changes in the reference levels relating to perceptions controlled in economic transactions will be likely to influence the dynamics of the entire economic system. In an HPCT structure, dynamic changes of all but the highest level reference values are almost assured, given that the highest level perceptions are as subject to disturbance as are any lower-level ones. You think a simplified homo will be good enough to provide good accurate models. I suspect that their interactions through the economic environment will invalidate that assumption -- obviously I have no evidence to support this opinion; that's just what it looks like to me.

Still, it may be that I am unduly pessimistic and you are realistic.

For now, I see you and Kenny as being respectively analogous to (you) the quantum chromodynamicist who understands the interactions of quarks and knows that with appropriate modelling he will be able to predict how to develop tunable dye lasers, and (Kenny) the chemist who knows that by mixing X, Y, and Z in the right timing and temperature conditions, he can get a dye that will lase as he wants. I wouldn't fault the chemist for questioning the chromodynamicist's ability to make the predictions in a humanly reasonable timescale, and I wouldn't fault the chromodynamicist for wanting to try. But I would fault either of them for insisting that the other's approach was wrong and unreasonable. Or that the two approaches were mutually contradictory.
