Theory vs. Reality: Why Market Absolutism Fails
| Ernest Partridge |

An economist and his guide, while hunting in Africa, fall into an elephant trap: twenty feet deep with vertical walls.

“That does it,” says the guide, “we’re done for. No escape, no food, no chance of being found in time.”

“Nonsense,” said the economist, “I can get us out of here.”

“And how do you propose to do that?,” the guide asks.

The economist replies: “Well, first we posit a ladder.”

Economists are no more inclined than the rest of us to live in a fantasy world – not, that is, as they go about the practical business of living their everyday lives. But when economists write technical papers and teach university courses, they often enter a theoretical realm of abstract concepts such as “economic man” (homo economicus) and “perfect markets,” articulated with virtuoso advanced mathematical manipulations. Very elegant, and very unreal.

Many economists, perhaps most, appreciate the limitations of economic theory in explaining and predicting social behavior and political trends. Some economists, however, claim to find in traditional (i.e. “neo-classical”) economic theory, the key to articulating and proposing public policy. It’s called “market absolutism,” and it has dominated American politics since the Reagan administration. It has also led this nation to the brink of economic disaster.

Market absolutism has led us to this crisis because its proponents in academia, politics and the media have been bewitched by theoretical concepts that apply imperfectly, if at all, to the real world in which we live and work. In particular: they posit an imaginary creature (“economic man”) that inhabits a mythical environment (the “perfect market.”)

Economic Man (Homo Economicus)

In neo-classical economic theory, “economic man” is a hypothetical individual who is a complete egoist, motivated solely by the self-interested desire to maximize his “preference satisfaction.” Homo Econ’s motivation is manifested by his willingness to pay for these satisfactions in a “free market.” Neo-classical theory also postulates that “all goods that matter to individuals ... must be capable of being bought and sold in markets” and “anything that is valued instrumentally ... can be handled by economics, be it acts of friendship or love.” (Freeman and Edwards. For citation of sources, http://www.igc.org/gadfly/progressive/prices.htm">follow this link). “Economic man’s” behavior is described, in neo-classical jargon, as “rational.” By implication, the self-sacrificing behavior of saints and heroes is “irrational.”

Clearly, “economic man” exists nowhere outside of Ayn Rand’s novels and, perchance, on Wall Street. And this is fortunate, for we wouldn’t want him for a neighbor.

In fact, there is much more to a fulfilled and moral life than self-interested “preference satisfaction.” Such a life also includes values that can not be priced in a free market. Among them:
  • Truth. Scientists and scholars offer evidence and sound arguments, not bids. In courts of law, purchased verdicts are not only invalid, they are crimes.

  • Civic Values such as justice, due process, civil rights, and the franchise, are not for sale. The governing impulse of economic man (qua consumer) is “I want.” The governing impulse of the citizen is “we need.”

  • Distributive Justice. The economic concepts of “efficiency” and “utility maximization” do not touch upon the moral issue of the just distribution of wealth. “Just compensation” and "fair distribution" are moral, not an economic, concepts. A slave economy can, in classical economic theory, be perfectly “efficient” (i.e., "Pareto Optimal").

  • Love, friendship and loyalty which is bought is less valuable than that which is given freely. As philosopher Mark Sagoff reminds us, “a civilized person might climb the highest mountain, swim this deepest river, or cross the hottest desert for love, sweet love. He might do anything, indeed, except be willing to pay for it.”

  • Moral values, which refer to http://www.igc.org/gadfly/progressive/prices.htm#prices">the worth of persons, are systematically excluded from neo-classical economic theory.

  • A public policy for “economic man,” systematically detached from criteria of truth, civic value, distributive justice, friendship and loyalty, is a policy that any civilized person should reject, and reject on non-economic grounds. (See my “http://www.igc.org/gadfly/progressive/prices.htm#economics">Why Economics Fails as a Sole Foundation of Public Policy,” for an elaboration of these points and a citation of sources).
The Perfect Market

Neo-classical economists, and their political acolytes, are convinced that “free markets,” completely undisturbed by government interference, yield optimum social and economic results. For example:

“In the free market, the individual would have to produce a good that the other person desired in order to receive a good in return. Adam Smith's "invisible hand" of the market guides all participants in society to promote the best wishes of everyone else by pursuing his own wants and desires.” (Jacob Halbrooks)

“(T)he free market allows more people to satisfy more of their desires, and ultimately to enjoy a higher standard of living than any other social system... We need simply to remember to let the market process work in its apparent magic and not let the government clumsily intervene in it so deeply that it grinds to a halt." (David Boaz, Libertarianism, a Primer, p. 40, 185.)

"A free market the activity of millions of people, each seeking his own interest, in such a way as to make everyone better off... Economic order can emerge as the unintended consequence of the actions of many people, each seeking his own interest." (Milton and Rose Friedman: Free to Choose, pp 13-14).

History has taught us, time and again, that such assertions are true only in the purely abstract world of neo-classical economic theory. They are not true in the real world that we inhabit. To understand why this is so, we need only list the conditions of “the perfect market” postulated by economic theory.
  • All participants are “perfectly rational” egoists – i.e., are “economic men.”

  • There are many participants in the market.

  • All participants have access to all relevant knowledge.

  • There are no transaction costs.

  • All transactions are mutually beneficial.

  • There are no externalities (i.e., consequences to non-participating “third parties”).
Clearly, there are no “perfect markets” anywhere on earth, apart from the imaginations of economists. For consider:

(a) “Economic man” is a myth, or at the very least extremely rare. As noted above, most individuals engage in economic transactions for several reasons, some of them non-economic.

(b) Participation in markets is restricted to those with the ability to pay. Public policy decisions, on the other hand, should involve the rights and welfare of many who are systematically excluded from market activity; namely, the very young, the very poor, animals, and future generations. Furthermore, unregulated markets are self-eliminating, because capitalists detest competition and strive constantly to eliminate it. The remedy? The enforcement of anti-trust laws and regulation, which means, of course, “interference” by governments in the marketplace.

(c) The multi-billion dollar advertising and public relations industries are devoted to the task of persuading rather than informing. And persuasion involves the withholding of relevant information (e.g. health risks) and the dispensing of distorted and false information. Caveat Emptor!

(d) All transactions in the real world exact costs. Among them are the costs of enforcing the laws required for markets to take place at all (e.g. fair disclosure, patents and copyrights, contracts, civil and criminal courts, etc.), and this of course means government, which is so despised by “free marketeers.”

(e) Transactions are frequently not mutually beneficial, due to fraud (i.e., violation of “relevant knowledge condition”), the remedy of which is civil suits, which requires the “transaction costs” of the enforcement of law and the appeal to courts.

(f) External costs of market transactions are more the rule than the exception. Innocent, non-consenting parties are routinely impacted by economic activity. Among these external costs are environmental pollution, urban decay, public health costs, etc. Third-party “stakeholders” have no say in economic transactions. Their only recourse for protection and compensation is to the sole agency legitimately established to represent all citizens: the government. (See my “http://www.crisispapers.org/essays7p/invisible.htm">Market Failure: The Back of the Invisible Hand”).

Summing up: “Economic man” and “perfect markets” are abstract constructs which, due to their clarity and simplicity, allow theoretical economists to devise complex mathematical models. However, they have no counterparts in the real world, which compromises the application of these concepts in public policy.

Case-In Point: Milton Friedman on Free Trade

Foreign trade and currency exchange rates provide a vivid example of the rule, “The theory is beautiful, but reality is baffling.”

According to free market theory, foreign exchange rates should be self-regulating, negative feedback functions, like house thermostats. The heat rises, the furnace shuts off, the heat drops, the furnace kicks in, perpetuo moto.

Similarly with foreign trade. If there is a “trade imbalance,” say between Japan and the United States, as dollars go to Japan and consumer goods are imported to the U.S., the Japanese will acquire a surplus of dollars causing the value of the dollar to fall with respect to the yen. U.S. consumer goods will then be less expensive than Japanese products, thus encouraging a flow of the yen to the U.S. to purchase American goods. Then the value of the dollar will rise until foreign goods once again become competitive. And so on, back and forth, like a thermostat. It’s all perfectly automatic – a “spontaneous order,” as the libertarians call it – no governmental interference (e.g. tariffs) required.

This is how Milton Friedman describes it:

If foreign exchange rates are determined in a free market, they will settle at whatever level will clear the market. The resulting price of the dollar in terms of the yen, say, may temporarily fall below the level justified by the cost in dollars and yen respectively of American and Japanese goods. If so, it will give persons who recognize that situation an incentive to buy dollars and hold them for a while in order to make a profit when the price goes up. By lowering the price in yen on American exports to Japanese, it will stimulate American exports; by raising the price in dollars of Japanese goods, it will discourage imports from Japan. These developments will increase the demand for dollars and so correct the initially low price. (Milton and Rose Friedman, Free to Choose, p. 47).

In theory, it’s all very neat and so simple: “all things being equal.” But in the real world, “all things” are never equal. Instead, the ecologist’s rule applies: “you can’t do just one thing.”

What if that flow of dollars abroad is accompanied by a dismantling of the U.S. industrial base? Then, when the time arrives for U.S. manufacturing goods to be competitive with foreign goods (due to the weakening of the dollar), there will be no more American-made goods on the market. Moreover, with the outsourcing of U.S. jobs overseas and the decline of median disposable income, fewer American can afford to buy foreign consumer goods. Regressive tax rates cause the nation’s wealth to flow to the very rich, who send their investments abroad in outsourced industries. A shrinking tax base results in a disintegrating physical infrastructure and a decline in higher education, followed by fewer scientists and engineers, and less basic research and development. Thus today the United States excels only in military technology, as it needlessly spends more on the military than all the rest of the world combined, building 3.5 billion dollar aircraft carriers to fight an “enemy” without an air force, and billion dollar submarines to fight an “enemy” without a navy.

This is what happens when public economic policy is abandoned to “the will of the free market” – an abstraction with, we are expected to believe, a benevolent “mind” of its own. This is what happens when a government puts the fate of the nation’s economy in the hands of wealthy individuals and corporations; individual agents without social conscience and with nothing more than their short-term profits in mind.

In the face of such grim realities, the neat “negative feedback” model of Friedman’s free-trade theory is irrelevant. It belongs to the abstract world of “theory,” not to the real world. In the real world, the thermostat is broken, the furnace will not turn on: down, down, down, goes the temperature.

“Physics Envy:” Formal modeling vs. Empirical Investigation

Neo-classical economists regard themselves and their discipline as more “formalist” than “empirical.” “Applied economists” such as John Kenneth Galbraith, Kenneth Boulding and Herman Daly who study the behavior of markets in “the real world” and attempt to draw inferences and conclusions from these studies, are regarded as an inferior caste: they rarely win Nobel Prizes and are conspicuously absent from the rosters and the publications of right-wing and libertarian think-tanks. (The remainder of this section is adapted from my “http://www.igc.org/gadfly/progressive/economics.htm#theory">Beautiful Theory vs. Baffling Reality”).

Economic formalists are ever-ready to offer explanations of the state of the nation’s economy, and to issue warnings of dire consequences if their recommendations are not adopted, a willingness that is compounded as the economist’s academic training is mixed with his political sentiments and motives.

Consider, for example, an analysis of the prosperity of the Nineties, the longest sustained economic boom in our history. Who gets the credit? The Democrat replies, “Why Bill Clinton, of course!” “Not so fast,” says the Republican economist. “That prosperity was a time-lagged result of the policies of Bush I, aided by the wise legislation of the Republican Congress after the GOP took control in 1995.”

And what caused the stock market bust and recession early in the Bush II administration, and the humungous deficits that followed? Quoth the Democrat: “Clearly, those tax breaks to the rich failed to ‘trickle down’ and stimulate economic growth as the GOP promised.” “Wrong again,” says the GOP apologist. “The bust and the recession were “time-lag” effects of Clinton’s horrible economic policies. As for the stimulus from the tax breaks, be patient – just you wait.”

I trust that you can see where this is going. “Time lag” – the gift to the economic theorist that keeps on giving -- is just one of several “explain-away” devices that economists fall back on, when their policies and predictions don’t quite turn out right.. Whenever “our” policies fail, or “their” policies succeed, there is always one or another of a myriad of macroeconomic imponderables to fall back on for an explanation. It’s no wonder that the disputes that ensue are never definitively resolved.

The problem is not that economic theories explain too little – it's that they “explain” too much, so that whatever happens, their defenders have an “explanation,” and likewise, their opponents have a contrary "explanation." That’s just another way of saying that politically motivated economic projections and explanations are “non-falsifiable,” and non-falsifiability is the definitive mark of non-science.

Astronomers can predict within seconds, eclipses hundreds of years into the future. If economists had a reliable 60% success rate in their macro-economic predictions, they could all retire at forty on the returns from their stock market investments. And as we all know, they don’t.

Please understand: I am not "anti-markets." The failed economic experiment in the Soviet Union proved conclusively that a centralized command economy is vastly inferior to a market-based system of pricing, distribution, innovation and quality control. Having "shopped" in both the Soviet Union and the United States, I know this from personal experience. Furthermore, because human beings in significant aspects of their lives, do, in fact, act upon economic motives, a scholarly examination of market behavior has valuable implications for numerous disciplines, including environmental studies and political science.

In short, I do not assert that a study of markets and economic theory should count for nothing. Instead, I protest that they should not count for everything. Homo economicus is an ingredient of our nature that we would be well advised to study. But our lives consist of much more than buying and selling. We also love and we sacrifice, and we have goals and concerns that transcend our self-interest. And we seek, both personally and collectively, truth, justice, and personal excellence, none of which can appropriately be bought or sold in markets

With this conviction, I am joined by many esteemed economists, among whom are some of the severest critics of neoclassical economics. These include Herman Daly, Nicholas Georgescu-Roegen, Kenneth Boulding, Paul Krugman, James Galbraith and Amartya Sen, all of whom possess a clear view of the limitations of their discipline. Indeed, my quarrel is less with economists than with politicians and policy-makers who have skimmed easy formulas and simplistic generalizations off the top of the neo-classical economic theory, and put them to work in behalf of their special political and economic interests.

Even so, the above-listed dissenting economists, whom I admire enormously, report that there is in fact a dominating "orthodoxy" of neo-classical thought in the discipline of theoretical economics, and that this orthodoxy has had enormous influence upon both public policy and politics.

I can validate their report with my own experience. Often, when I have mentioned the names of these mavericks to economist colleagues, I find that I have evoked stares of disbelief or even condescension, such as one might expect from a fundamentalist preacher upon hearing the name of Charles Darwin. I once asked Herman Daly why he is regarded as an “outsider” by the mainstream of his profession. He wryly replied that it was probably because he permits the elegance of formal economic theory to be contaminated by compelling facts of biology and physics. Meanwhile, the true believers read with admiration the pronouncements of economists such as Julian Simon, who confidently assert that the omnipotence of the free-market and the omniscience of future entrepreneurs can overcome trivial physical constraints such as the second law of thermodynamics. (See my “http://www.igc.org/gadfly/papers/cornuc.htm">Perilous Optimism”). I once heard Paul Ehrlich remark to Johnny Carson that if an engineer proposed to design an aircraft for an exponentially expanding crew, he would rightly be regarded as mad. Yet when an economist proposes an economic model that posits perpetually expanding population and resource consumption, he is regarded as eligible for the Nobel Prize for economics.

Happily, this era of free-market dogmatism may be coming to an end, as the dreadful consequences of its application are cascading upon us. Some of the High Priests are, in the face of stark economic realities, abandoning the cult. Leading the way is http://www.smirkingchimp.com/print/19063">Alan Greenspan, who told Henry Waxman’s Committee, “those of us who have looked to the self-interest of lending institutions to protect shareholder’s equity (myself especially) are in a state of shocked disbelief... I made a mistake in presuming that they were best capable of protecting their own shareholders.”

The dogma of market absolutism may, at long last, be replaced by what http://www.journaloflawandsocioeconomics.com/Galbraithluncheon0302.pdf">James Galbraith calls “a new spirit of pragmatism, “ which, he writes, “surely requires that we discard the metaphor of market determinism – whole and entire. No more, let us bow and scrape before that altar. Markets have their place – they are a reasonably open and orderly way to assure the distribution of services and goods. They are not a general formula for the expression of social will and the working out of social problems.”

Thus might the economic strategy of FDR’s New Deal be reinstated: constancy in ends – national prosperity and economic justice – and flexibility in means. “Don’t just sit there, do something! If it works, keep it. If it fails, try something else.” In economics, as with any viable science, theory must be tested in the real world, whereupon the theory is either validated, modified, or discarded.

Looking back through history, we might wonder how it is possible that intelligent and educated people once accepted uncritically such notions as astrology, judicial trial-by-combat, the demon-possession theory of disease, and alchemy. Today, more and more sophisticated observers of society and politics are wondering how homo economicus, a creature bereft of sympathy, humanity, and noble aspiration, and "the perfect market," a "place" devoid of any social contacts more elevated than market transactions, ever came to be regarded by our political elites as the foundation of a just political order.

1. Economics is a wonderful tool, but it's just that - a tool.
It's imperfect and full of flaws and models what would happen in an ideal world, just as you say in your post.

Honestly, I think neo-liberalism has a potential to work as planned in the extremely long-run (I'm talking centuries). However, as John Maynard Keynes said, "In the long run, we're all dead." Economists and businessmen should work towards long-term goals that will ultimately benefit society, but they cannot be divorced from immediate circumstances and problems.

4. Neo-Classical economics is a good theory
that does not work in reality. It's impractical and ideologically extreme.

It's worth noting that Adam Smith, the demigod of this ideological movement, was himself a moral philosopher.

that contemporary free market absolutists are often loathe to acknowledge. He wrote, for instance, of the harm caused by individuals who had accumulated huge amounts of personal wealth using that wealth to influence law, anticipating modern corporate lobbying.

Kind of like the Religious Right with the Bible. Think there's a connection?

Good job on the writing, Ernest. You elaborated on what I've been saying for years and gave specific rebuttal points.

5. A delightfully clear, rational post
I'm a software developer with a keen interest in AI (and, as a result, human intelligence and its biological basis). I've watched simplistic attempts at AI, premised on very limited definitions of intelligence, fail to make the grade again and again. Some elegant tools have arisen out of such efforts (boolean logic comes from a 19th century attempt to explain human thought), but not intelligence as we understand it.

And every time some I've been exposed to the purportedly self-evident elegance and truth of free market absolutism, its struck me as being as idealistic and unrealistic as those overly simple theories of intelligence. What also struck me, again and again, was that so many of its most enthusiastic proponents are in some sense selfish and greedy.

I used to work with a very talented developer who just happened to have acquired a degree in economics before changing her mind and pursuing a career in programming. We had many fierce debates, which usually ended in her instructing me haughtily to read some work by Friedman, or Hayek or some other economist, that supposedly settled the issue. She was, as I've come to expect, entirely unmoved by beggars and such, holding the poor entirely responsible for their state in a country that suffered 40 years of Apartheid (and centuries of oppression prior to that), a country with one of the worst GINI scores in the world.

And despite her unshakeable confidence that she was vastly better qualified than me to comment on issues economic, she put forward a view of the real world that any lay person with a passing interest could see was wholely disconnected from reality. In her universe the formation of cartels, price-fixing, barriers to entry, the negative effects of inheritance on a meritocracy, inordinate influence of well-funded lobbyists on regulation and so on arise so rarely in a truly free market as not to be worth considering. Any example of the obvious failures of free market thinking were always blamed on whatever scraps of industry regulation still existed in the affected sector.

Even theoretical constructs demonstrating fundamental problems with simple ideas about self-interest did not sway her. Her answer to the Prisoner's Dilemma, for instance, was straight out of Rand, an (assumed a priori) moral rather than practical argument. Although the aggregated gain of both prisoners in the Prisoner's Dilemma is greater if both prisoners are more willing to risk losing all to protect each other, her view was that this collectively greater gain still represented the same individual gain to each participant, which she considered paramount, with greater risk to each participant. Thus, in her view, it was a more morally sound result if one ratted the other out instead of both going free.

Did I mention she lacked compassion and was selfish in her dealings with the less fortunate? In any event I don't have a particular beef with this person. We got along reasonably well. She just stands out as an example of the many intelligent but shallow personalities that have nurtured free market absolutism and made it a dogma in recent decades. Her venal, biological biases were self-evident in every other confident declaration she made.

The orthodoxies of economics I've been exposed to in the last two decades often left me shaking my head in amazement, in much the same way that physicists like Sokal found themselves gobsmacked by the gibberish emanating from many post-modern commentators in the domain of science. In much the same way that many intelligent non-psychologists can only stare, open-mouthed at the astonishingly naive "just-so" stories that are often the hallmark of evo-psych.

8. A familiar experience
There are some similarities between AI and economics. In both fields the important problems are simply too hard to tackle in earnest -- beyond our current capabilities. As a result both use models that are hopelessly simplistic and too limited to be of use except in very specialized domains. Still AI, on the whole is in better shape. AI researchers understand the current limitations of their theories because they can be evaluated in a controlled fashion in a lab or on a computer.

7. Thank you. I have long been puzzled with this worship at the alter of "free" markets.
Economic activity is still human activity and as such is vulnerable to all the ill, as well as the good, deeds of humanity. The issue seems to be not whether or not there are "free" markets, but who controls the the markets. Sitting here with my needlepoint and watching the occasional Jane Marple mystery DVD, this has seemed glaringly obvious to me.

10. My Managerial Econ prof was a Friedman fanatic
Edited on Wed Dec-17-08 03:20 PM by Autonomy
and he used to say things like:

"The minimum wage hurts black people because they cannot work for $2/hour."

"It's justifiable that women make less for the same job because they have babies, which costs employers money over time."

When challenged with facts like:

"Men cost more because women, statisitically, stay at a job longer than men,"

He respond with the fact that he does not believe in statisitics, and it cannot be true. If it were true, women would get paid more than men. Why? Because the model says so.

11. Some of this is just plain wrong.
Several things jump out at me.

First, "homo economicus" is essentially a straw man: the "utility" rational individuals maximize has no predefined content. Other people's welfare can be part of my utility if it is one of the things upon which I base my economic decisions. The theory works just as well in that case.

Second, while it is true that economics is expressed through ideal models, this is no more an inherent indictment of its conclusions than the fact that physics and chemistry use ideal models means that their conclusions are wrong. What is required for accuracy in both economics and in the physical sciences is a recognition of what the simplified models leave out, and an attempt to account for them--and economists do this all the time. For instance, mainstream neoclassical advocates of radically free-market policies don't just point to basic general equilibrium theory and pretend that that is the be-all and end-all: what they say instead is that while laissez-faire is imperfect in a variety of ways, government intervention in the real world is more imperfect. (I post here because I think they are wrong. But it's worth actually understanding where they are coming from.)

Third, "Pareto-optimality" is not the only standard economists use to judge public policy. Welfare economics is much broader than that; there's simple utilitarianism, there's the "capacities" approach (Sen's), and so forth.

Fourth, Partridge misunderstands the nature of global trade. It cannot be that there are no American goods on the international market due to imports. If Americans do not receive foreign currency from other countries buying American goods (or investing in the US economy), Americans cannot buy foreign imports. Think of the equivalent on the individual level: if I don't produce anything that you want to buy, I have no money with which to buy the goods you produce.

12. Some comments on your observations
In regard to "homo economicus", you seem to me to be conflating an idealized prototype with "any real individual". It is my understanding that any specific personal preference, referred to in the free marketeer theory, is washed out by the aggregate nature of the prototype. IOW, altruism becomes an inconsequential motivation when considering the "average, aggregate person" over time. For this idealized person, economic gain ALWAYS = personal wealth/power SOLELY.

And no sane economist would ever attempt to predict the behavior of any given individual in the real world. The only person they are concerned about is this idealized person. So when it comes to creating a public policy or politic, the system/model is reduced to the assumption that money is the sole factor in decision-making.

Second, I have issue with your comparison of economics with the physical sciences. As the OP mentions, "free marketeers" do not accept, or explain away, any falsifying evidence.

Again, this jibes with my own limited experience with the free market economist. Their problem comes when attempt to apply their model to the real world. My above post is a few of the examples I've encountered in that regard.

13. Whatever The Free Market is...
I've really been thinking that there is a fundamental truth about the so-called Free Market.

It's somewhat good at giving us what we want.
It's exceedingly bad at giving us what we need.

So we get HD TV, Playstation 3, PinkBerry and Disneyland.
But we can't get healthcare, roads, fire departments & police.

Just an observation, that maybe, like church & state, want & need need to be separated.
