“Unregulated free markets are Pareto-optimal? Almost no one believes in that. This NYT article by Nobel Laureate Shiller is intellectually light-weight. It’s really nonsense. Mr. Shiller what about our criminal and civil laws…

…including those making fraud illegal and including business contract law (and its enforcement)? You don’t even mention them. And what about the economic fact that businesses that provide lousy or dangerous products and services and/or at uncompetitive prices, won’t be in business very long, as customers will abandon them rapidly (especially in this fast-information internet age)? Sure, we need common sense regulations, but we are way the HELL BEYOND common sense regulation of American free enterprise today Mr. Shiller….WAY BEYOND!!! By the way Mr. Shiller, you allude to Reagan-era  deregulation as the cause of the 2008 financial crisis and yet your only examples, below, of market manipulation and deception are “candy bars and gossip magazines at the checkout counter” (ignoring that minor impulse buys may have significant psychological benefits that benefit our health and/or the economy) and examples from the 19th Century, before we had any regulation at all!!! Pretty pathetic and liberally-biased Mr. Shiller. As you know, there are millions of buyers and sellers in free markets and yet only a relative “handful” of politicians and government “experts” decide for all of us the “optimal” type and amount of regulation of these free markets. With almost no accountability at all. How could they possibly know how to set just the right amount of regulation Mr. Shiller? Have you not read about the massive size of the Federal Register each year Mr. Shiller? Whose regulating the government regulators Mr. Shiller? How about every other year (or third year), rather than passing more new laws and regulations, the Administration and Congress eliminate ones they and their predecessors passed in prior years that aren’t working? That almost never happens Mr. Shiller, does it?”, Mike Perry, former Chairman and CEO, IndyMac Bank

Faith in an Unregulated Free Market? Don’t Fall for It

By ROBERT J. SHILLER

Perhaps the most widely admired of all the economic theories taught in our universities is the notion that an unregulated competitive economy is optimal for everyone.

In this optimal economy, each person is said to be a free actor who makes decisions purely in his or her own self-interest. Economists on both the right and left commonly say that these fundamental ideas tie our values of freedom and individuality to the success of our economies.

The problem is that these ideas are flawed. Along with George A. Akerlof, university professor at Georgetown and a fellow Nobel laureate in economic science, I have used behavioral economics to plumb the soundness of these notions.

In our book, “Phishing for Phools: The Economics of Manipulation and Deception” (Princeton, 2015), we question the all-commanding relevance of the free-market theory to our actual lives and economies. While we confirm the importance of free markets, we have found that market regulation has been crucial, and believe that will continue to be true in the future.

Don’t get us wrong: George and I are certainly free-market advocates. In fact, I have argued for years that we need more such markets, like futures markets for single-family home prices or occupational incomes, or markets that would enable us to trade claims on gross domestic product. I’ve written about these things in this column.

But, at the same time, we both believe that standard economic theory is typically overenthusiastic about unregulated free markets. It usually ignores the fact that, given normal human weaknesses, an unregulated competitive economy will inevitably spawn an immense amount of manipulation and deception.

We use the word “phishing” as a metaphor for a range of seemingly harmless modern market manipulations — like putting candy bars and gossip magazines at the checkout counter, where bored or tired adults and the parents of whining children will be tempted to spend a few extra dollars. And we coined the word “phool” to describe someone who does not understand how much thought and effort have gone into manipulating him or her.

These activities are widespread not because people in business generally have evil motives, but because of the existence of market forces — a phishing equilibrium enforced by competition. It works this way: When you realize that your competitor has used sophisticated and effective marketing tricks, then you will fall behind if you don’t follow suit.

Some businesses try to resist this trend on their own. Stores experimented decades ago with eliminating candy from checkout lines, for example, hoping to impress customers with their morality, but these efforts have largely failed. When profit margins are tight, those businesses that do not phish may simply be driven from existence.

Many economists see evidence of manipulation and deception in the marketplace, but most do not view the phenomena as a fundamental and ubiquitous problem with unregulated free markets. Deception and manipulation are inadequately discussed in textbooks on theory. As a result, market regulation is excessively maligned.

We see things differently: The success of the United States economy — and of those similar to it — can be attributed both to the relative freedom of its markets and to the fact that common-sense regulation has been imposed on them. Fortunately, many countries’ civil societies have injected a sense of morality into market activities.

The Thatcher-Reagan revolution a third of a century ago was a turning point away from market regulation, with mixed results. But the academic world’s formalization of free markets into mathematical economics supported that revolution with limited reservations.

Students in economic theory are now taught with few caveats that a competitive free-market economy will bePareto-optimal,” in homage to the economist Vilfredo Pareto. If you haven’t studied economic theory, a little explanation is in order.

A Pareto-optimal economy is achieved when it is impossible to make any one person better off without making at least someone worse off. That theory holds that each person makes economic decisions that result in the best possible outcome for that particular person. In economic jargon, each person individually maximizes a “utility function” that represents his or her own welfare. This theory is taught in manytextbooks as the “first fundamental theorem of welfare economics,” and is presented with mathematical elegance. Protests against this theory, which were once common, have largely disappeared.

It’s worth noting, though, that the first protest came from Pareto himself. He did not intend to use his insights in the manner in which they are commonly employed today. Pareto observed that his concept of optimality neglected some important moral dimensions: People in free markets do not really manage to maximize what the philosopher Jeremy Bentham would call their utility. They don’t always succeed in maximizing their true welfare, but something else, something much more limited.

In 1918, Irving Fisher, the Yale economist, argued that what people maximize in their actions is something that could better be described as“wantability” rather than utility, for they are subject to temptation and mistakes in the vast array of purchases they make, leading profit-maximizing marketers to take advantage of them on a systematic basis.

In the first half of the 20th century, such critiques were of general interest. But they are little discussed today.

Current economic theory does recognize that if there is an “externality” — say, a business polluting the air in the course of producing the goods it sells — the outcome won’t be optimal, and most economists would agree that in such cases we need government intervention.

But the problem of market-incentivized professional manipulation and deception is fundamental, not an externality. In short, the superiority of untrammeled free markets — the fundamental theorem of welfare economics — has taken on the aura of a law from the heavens. Yet technology has advanced so that temptations are being manipulated ever more effectively.

In fact, the real success of economies that embody free markets has much to do with the heroic efforts of campaigners for better values, both among private organizations and advocates of government regulation. For example, before 1900 most of the patent medicines that were sold to the public were fraudulent.

Most of these frauds have since been eliminated, not by market forces, but by the activities of private citizens who took action not selfishly but for the public good. Examples include Harvey Washington Wiley (1844-1930) and Alice Lakey (1857-1935), whose campaigns led to the foundation of the Food and Drug Administration in 1906, and Stuart Chase (1888-1985) and Frederick J. Schlink (1891-1995), whoseadvocacy in the 1920s led to the establishment of Consumer Reports in 1936.

Unfortunately, such giants have not become truly famous and have been largely forgotten. Contemporary heroes tend more often to be entertainers or businesspeople who are little more than masters of manipulation. Maybe the reason is that the heroes’ criticism ignites doubt about many of our own day-to-day activities.

We have lapsed into a mode of thought that glorifies free markets and belittles economic heroism. We need those markets, but we need real heroes, too.

  1. We have almost no concept of unregulated free markets and I doubt that these are the singular focus of our colleges as he suggests….and he almost suggests that candy at the checkout line should be regulated…what a joke and another slam about the government being better at making decisions for us…down to the level of buying a chocolate bar…what a joke!
