Academic Adler sets out to explain the key concepts and theories of mainstream economics and less known alternatives. The book considers the two cornerstones of economics. One is economic efficiency and its definition, which at one time included distribution of income but now focuses upon free markets as efficient, ruling out government intervention to decrease inequality. The second cornerstone is what a worker earns, is not based on the value of an individual’s contribution to production, which the author contends is a flawed concept; wages are determined by the power workers possess or do not possess at the bargaining table, and Adler points to CEOs’ “obscene” compensation, which he concludes is awarded because they work for shareholders who are too numerous and lack control. Everyone will not agree with the author, but he makes thoughtful arguments intended for educated readers who are not schooled in economics. This excellent book will add a controversial perspective on critical issues of our time for many library patrons. — Mary Whaley

Moshe Adler, Economics
for the Rest of Us: Debunking the Science that Makes Life Dismal.
Do you, like Chuck Berry, “go for that rock and roll music”? Do you yearn to take your “loved one over cross the tracks,” or anywhere else, to hear some up close and personal?
Then maybe you’ve been wondering, over recent years, why the bands you adore seem to be touring less these days — and charging more for the concerts they do give.
Or maybe you worry more about Social Security checks than concert tickets. And maybe you wonder why the average Social Security check today doesn’t reach what an elderly person needs to pass the poverty line.
Or maybe you wonder why the CEO at the company where you work makes more in a morning than you make in a year.
You have questions. In his new Economics for the Rest of Us, Moshe Adler has answers. Good ones. And his answers all revolve, sooner or later, around our world’s increasingly unequal distribution of income and wealth — and power.
Adler teaches economics at
Economics for the Rest of Us blasts away against that theory — and all the other contortions economists go through to make the case that “what's good for the economy” must always be what’s “good for the rich.”
In fact, as Adler explains with entertaining examples, growing concentrations of income and wealth at society’s summit make our lives far more “dismal” than they would be if we distributed resources and power more equitably.
Take those rock concerts, for instance. Back in 1980, in a considerably more
Fast forward a generation. By 2003, only 26 percent of concerts charged the same price for all seats. And the best seats had increased the most in price.
Nothing strange, notes Adler, in any of this. In a relatively equal society, with little difference in income between the rich and everyone else, monopolistic vendors have “little to gain from selling only to the rich.” But that all changes when the rich go mega. Vendors can charge more for their wares — and not worry if their less affluent customers can’t afford the freight.
The end result of this rising inequality: Average-income rock fans, observes Adler, “must now content themselves with fewer live concerts because rock stars can now make more money charging higher prices and performing less.”
To add insult to injury, a growing number of the gigs rock stars do perform come before audiences open to rich people only. Elton John charges $1.5 million for a 90-minute performance at a private party. The Rolling Stones: up to $10 million.
In the grand scheme of things, of course, our world can survive the shenanigans of ungrateful and greedy rock-and-rollers. But the same dynamics of inequality that aggravate rock fans help explain why so many people can’t afford AIDS drugs or stay in college or buy a home.
So what do we do? We need to ditch the “pseudoscience” that mainstream economics so often propagates, Economics for the Rest of Us advises, and press for new economic rules and regulations that can “check the unfair distribution of the fruits of our labor.”
One such rule, suggests author Adler, could “set a maximum ratio at any given company between the highest executive compensation and the lowest worker's wage.”
Most economists won’t like that notion at all. After spending some time with this invigorating new read from Moshe Adler, you most likely will.

Science is often thought to proceed from a theory to experiments that test its predictions. If new data are discovered that cannot be explained by the theory, eventually a new theory arises to replace it. If the new theory can explain everything the old one did plus the new phenomena, sooner or later every scientist will adhere to the new paradigm.
Neoclassical economics is taught in every college classroom in the
But the authors of the three books under review deny categorically that neoclassical economics is a science. Economists have taken certain scientific concepts (such as equilibrium, stability, efficiency, feedback loops) and certain mathematical and statistical techniques and notions (such as calculus, probability, normal distribution, randomness, independence) and applied them to society in ways both inappropriate and simple-minded. Each of these writers concludes that, while economics has scientific pretensions, it is primarily an ideology that supports the interests of the rich and powerful, and in the process, confers prestige, influence, and money on its practitioners.
Modern Political Economics gives us the most sophisticated account of the surreal character of neoclassical economics. This book is not for beginners; a prior understanding of economics is required to get through it. And patience, as it is more than five hundred pages long. However, its deconstruction and demolition of neoclassical economics is devastating. Yanis Varoufakis, Joseph Halevi, and Nicholas J. Theocaratis show us in superb detail how economists have constructed a model of the capitalist economy that assumes it is exactly analogous to a flawlessly operating machine system (they use the movie The Matrix to good effect as an example).
Neoclassical economists assume that society is made up of independent, self-interested, and all-knowing human beings, who come together in marketplaces over which they exert no control, and all at once arrive at agreements in such a way that every market clears. That is, a price is established at which the supply of every single commodity equals the demand for it. Furthermore, the general equilibrium achieved is one of maximum social efficiency. It is what economists call “Pareto efficient,” after the Italian economist Vilfredo Pareto; it describes an equilibrium such that no change away from it can make at least one person better off without making anyone else worse off.
Such an economy bears no resemblance to any actual existing economy, nor could it. There is no money in it, no government, no notion that there is a natural world in which production occurs, no workplaces. It is constructed in abstraction from the distribution of wealth and income. It is like a Georgio de Chirico painting, timeless and idealized. Yet, in an act of stunning legerdemain, neoclassical economists employ this imaginary model as if it were the ideal system of production and distribution, the only one that can be used to judge how well any contemporary capitalist economy is performing.
Since the notion of social efficiency has been defined prior to its building, and the equilibrium set of prices satisfies this definition, it follows that any deviation from equilibrium will be inefficient. Economists use this model to argue the undesirable consequences of minimum wage laws, labor unions, price controls, rent controls, income taxes, environmental regulations—indeed just about anything a government does. Because government actions will almost surely harm at least one person, they, by definition, must be ruled out. In addition, all attempts by governments to counteract unemployment (which can only be caused by some external and temporary shock to the economy, such as a drought or a flood) will be self-defeating, since the all-knowing buyers and sellers will immediately act to nullify the desired results of the government policymakers. Economist Robert Pollin put it well in a stinging critique of neoclassical luminary, Robert Lucas:
To begin with, Lucas assumed that people carried in their heads a fully worked out and accurate model of how the macro economy functions. In the event that the Federal Reserve tried to stimulate the economy and expand job opportunities by lowering interest rates, all rational people, working with the accurate macroeconomic models in their heads, would know that this initiative would end up causing inflation. More precisely, they would calculate how much inflation would be produced by the Feds intervention, and as such, they would also know that this acceleration of the inflation rate would erode how much they could buy at the given wage they were being paid. The workers would therefore realize that they would be foolish to deliver the same level of work effort until their wages were raised to compensate them for the rise in inflation. The unemployed would similarly refuse job offers whose wages did not account for the erosion of their buying power that would result through the inflation that they would have accurately anticipated.
I remember in the 1980s challenging my Ph.D. students to help me carry out accurately even one of the multiple calculations Lucas claimed anyone could and did perform on a regular basis. Needless to say, we all failed the assignment, and I have no doubt that Lucas himself would have failed. The reason was simply that there was no possible way anybody could know all the things that Lucas blithely asserted everyone knows as a matter of course.

There is much more to Modern Political Economics than a skewering of neoclassical economics. It is, in fact, an exceptional history of economic thought. The authors explicate the economic ideas of every major thinker: Aristotle, the Physiocrats, Adam Smith, David Ricardo, Karl Marx, Leon Walras, Alfred Marshall, Kenneth Arrow, Gerard Debreu, Paul Samuelson, John Nash, John von Neuman, John Maynard Keynes, Milton Friedman, Friedrich Hayek, Michal Kalecki, Paul Sweezy, Robert Lucas, Eugene Fama, and many more. Their intellectual history is the prelude to an examination of the Great Recession triggered by the bursting of the housing bubble. The authors argue that the failure of mainstream economists either to see that an economic collapse was coming or to know what to do about it was due in large part to what they call “lost truths” and “inherent errors.”
For example, Ricardo’s model of the capitalist economy has considerable logical purity. But following his attempt to show, within one grand framework, both how the economy grows over time and what determines the ratio of one price to every other price (something the authors say is impossible and represents the “inherent error” of all general economic theories), Ricardo concluded that there could not be an economic crisis caused by insufficient aggregate demand for goods and services. He ignored the challenge to this position made by Sismondi and Malthus, and Ricardo’s superior intellect, wealth, and prestige helped to allow an important “truth” to be lost for a century, until John Maynard Keynes resurrected it during the Great Depression.
Both Economics for the Rest of Us and Economyths skewer the glaring deficiencies of neoclassical economics in a less formal manner. The former book is full of interesting insights and would make an excellent textbook. It is divided into two, interrelated, parts. Part One challenges the use of Pareto optimality. Adler resurrects Utilitarianism, an older measuring rod first developed by Jeremy Bentham, which says that a society should always do those things that give rise to the greatest happiness (utility) for the most people. Bentham assumed, as most of us would, that an extra dollar yields a lower utility to the rich than to the poor. Maximum social utility is therefore highest when everyone has the same income. This is a radical idea indeed, and this is why Pareto attacked it so harshly. With Pareto’s approach, we have no way to judge any public policy, since some will inevitably be hurt by it, while others will gain. Only when some win and not one person loses does Pareto give the go-ahead. And Pareto said that since it is impossible to measure utility, we cannot know for sure that an additional dollar will give less pleasure to the rich than to the poor person. Thus, there is no justification for government redistribution schemes.
But, with Bentham, we act whenever the gains to the winners are greater than the losses are to the losers. Combined with the argument that the utility of additional money falls, the more money a person has, Utilitarianism gives us ample justification for many public policies. Adler provides numerous clear and enlightening examples of eminently good public programs that have been routinely condemned by neoclassical economists. These include price controls for necessary medicines, subsidies to those with low incomes, Medicare, rent controls, progressive taxation, and anti-pollution laws—against which Lawrence Summers infamously wrote that it is socially desirable for rich nations to dump their toxic wastes in poor countries, since people there do not live long, and their lives are consequently worth less than ours in rich nations. (Adler’s discussion of Pareto and Bentham includes many subtleties not discussed here due to space limitations. However, these are well worth examining.)
Economics for the Rest of Us also describes some seldom discussed consequences
of growing income inequality. Adler first points out one of the major features
of modern capitalist economies, namely, the pervasiveness of monopoly or, to be
more precise, oligopoly—market structures in which one or a few large business
firms dominate production. Monopoly confers pricing power on the monopolist,
which leads to higher prices and smaller output than when markets are more
competitive. Next, Adler shows how growing inequality interacts with monopoly
power to deny access to goods and services to those in the middle and at the
bottom of the income distribution. He illustrates with clever examples,
describing how it is more profitable for a monopolist to cater to the rich.
Some physicians now refuse to accept health insurance, including Medicare, and
instead charge rich clients a yearly fee, which gives them fast access to
treatment (for which they pay in cash). Airlines increase the size of expensive
first-class compartments, even making seats that convert into beds, while the
remaining passengers are squeezed into smaller and smaller spaces. Rock stars
find it more profitable to perform at private parties for wealthy patrons than
for the masses at stadiums with reasonably priced seats. In
The remarkable thing is that, from the neoclassical point of view, the economic pie gets bigger even as inequality worsens. If a few rich patients pay more for a doctor’s services, then, other things being equal, the GDP is higher than it would have been if the doctor had welcomed all patients.
Despite Adler’s powerful arguments in favor of greater equality
(his section on education, where inequality is as dire as it is ignored by
education reformers, is a must-read), his neoclassical brethren say that
inequality is a good thing. What else would keep everyone working so hard? And,
as Adler tells us in the second half of his book, inequality is but a
reflection of unequal productiveness. Hedge fund managers deserve to make a
billion dollars a year and CEOs deserve to be paid hundreds of times more than their
rank-and-file employees because they are fantastically more “productive.” This
doctrine was systematically developed in the late nineteenth century by the
neoclassical economist John Bates Clark. It is worth reproducing a
The welfare of the laboring classes depends on whether they get much or little; but their attitude toward other classes—and, therefore, the stability of the social state—depends chiefly on the question, whether the amount that they get, be it large or small, is what they produce. If they create a small amount of wealth and get the whole of it, they may not seek to revolutionize society; but if it were to appear that they produce an ample amount and get only a part of it, many of them would become revolutionists, and all would have the right to do so. The indictment that hangs over society is that of “exploiting labor.” “Workmen” it is said, “are regularly robbed of what they produce. This is done within the forms of law, and by the natural working of competition.” If this charge were proved, every right-minded man should become a socialist; and his zeal in transforming the industrial system would then measure and express his sense of justice. If we are to test the charge, however, we must enter the realm of production. We must resolve the product of social industry into its component elements, in order to see whether the natural effect of competition is or is not to give to each producer the amount of wealth that he specifically brings into existence.
The gist of
Certain grim predictions flow from
The most outrageous neoclassical proposition is that the Great Depression can be explained by so-called “sticky” wages. Both free market extremists, such as Milton Friedman, and liberal moderates, such as Joseph Stiglitz, blame workers for mass unemployment. Friedman claimed that workers are unemployed because they will not accept lower wages when the demand for their labor falls. Erroneously believing that the demand for output has only fallen in their industries, workers quit their jobs rather than take lower pay, apparently too dumb to see that there is a general economic downturn. In point of fact, wages do fall in depressions, and workers are often willing to take whatever work they can find at whatever wage they can get. Keynes showed us that falling wages and prices can lead to uncertainty about the future, and this is what might keep unemployment high.
Stiglitz’s explanation is just as foolish as Friedman’s. He argued that employees are always trying to “shirk,” that is, work as little as possible. To prevent this, employers must pay a higher wage than is consistent with full employment. The resulting unemployment is just what is needed to keep those employed hard at work; they don’t want to lose their shirking premium. Again, little evidence is presented to support this idea. Stiglitz seems unaware of the compelling evidence offered by Harry Braverman and many others that modern workplaces have been so thoroughly Taylorized (designed and monitored to maximize employer control, per the dictates of Frederick Taylor) that shirking is nearly impossible.
Both Modern Political Economy and Economics for the Rest of Us conclude that neoclassical economics almost always shows a preference for institutional arrangements and public actions that benefit those who are wealthy and powerful. It is, to put it bluntly, an ideology that helps keep us ignorant of the exploitative class relationships that define capitalism. The author of Economyths would not disagree, although his critique of neoclassical economics is more eclectic. David Orrell is an applied mathematician without formal training in economics. This bothered one reviewer on amazon.com, but it should not have. An outsider can often give us deeper and more objective insights than an insider. We should not forget that Smith and Marx were trained in philosophy, Ricardo was a stockbroker, and von Neumann, a mathematician. We should be thankful that they did not have to endure the horrors of a graduate education in economics, as did this reviewer.
Orrell begins his lively book with a question both obvious and unanswered by mainstream economics. Why did economists not see that the economy was about to implode in 2007? He answers that the fault is in the fundamental assumptions they made. Orrell points to Eugene Fama and his “efficient market theory,” through whose lens, financial markets—and all markets, for that matter—were seen by the most sophisticated neoclassicals. The price of an asset, say a credit default swap, reflects all past, present, and future events that might influence it. That is, it is always “right.” The only deviations from the market price are the result of random, small shocks. Since they are random, they are predictable using the laws of probability and the normal distribution. What this means is that there could have been no housing bubble, no bursting of the bubble, and no Great Recession. A little more than a year ago, Fama told John Cassidy, “I don’t even know what a bubble means.” Indeed! They are ruled out by assumption, the entire chaotic history of capitalism notwithstanding. Fama blamed the government for the crisis, but if markets know all, shouldn’t they have anticipated what the government was going to do and responded in such a way as to mitigate the bad that would happen?
Orrell defines ten “economyths” and devotes a chapter to each one: (1) the economy can be described by economic laws; (2) the economy is made up of independent individuals; (3) the economy is stable; (4) economic risk can be easily managed using statistics; (5) the economy is rational and efficient; (6) the economy is gender-neutral; (7) the economy is fair; (8) economic growth can continue forever; (9) economic growth will make us happy; and (10) economic growth is always good. He explains the historical origin of each myth, often using an amusing story to make his point. He traces Summers’s “one set of laws works everywhere” to Pythagoras’s fascination with the regularity of numbers. Isaac Newton and his physics attracted the original neoclassical economists—William Stanley Jevons, Pareto, and Leon Walras are the ones Orrell discusses, giving a sympathetic account of each. The beautiful symmetry of supply and demand equilibrium derives directly from nineteenth-century physics. Unfortunately, human societies cannot be analyzed using the concepts of physics. They are too messy and complex; power of all kinds is critical to them but has nothing to do with the subject matter of the sciences; and, while the universe is indifferent to happiness, human beings are not.
Orrell suggests that economics has much to learn from modern discoveries in both the natural and social sciences. Although economies are complex systems and therefore not amenable to one-dimensional theories that aim to explain everything, it is possible to find “pockets of predictability.” If we cannot know when an economic crisis will occur or how deep it will be, we can perhaps predict that when we deregulate our banks, we will have problems. Our economies have much in common with networks, like electrical grids, and we can prevent a breakdown in one part of the grid from spreading and causing catastrophe by taking simple steps, such as insulating one part from another. One example would be to maintain a separation between commercial and investment banking. Another would be to have a backup plan, such as forcing financial entities to keep larger money reserves on hand at all times. In mainstream economics, more production is always good because we assume it will make us happier. However, sociologists, psychologists, medical researchers, and ecologists have found that more consumption and more possessions do not make us happier; that the negative consequences of growing inequality can outweigh any positive results of increasing output; that economic growth is destroying the planet. Economists ignore such research at their peril.
Let me end this review with some mild critical comments. None of these books tells us how to break the vice-like grip of neoclassical economics on both the profession and on most of the institutions of capitalist society. If almost all of it is grossly apologetic for the human misery and environmental degradation that form the body and soul of capitalism, how does it tick on, like the Energizer Bunny, despite the Great Recession that seemed to offer some hope that we would reject it once and for all? When the world’s financial markets were on the verge of a catastrophic breakdown, Alan Greenspan, the “maestro” of the markets, offered mea culpas at a Congressional hearing for adhering to an incorrect theory. Now he has recanted his apostasy. Everything was really all right, just as he had said before the bubble burst.
Modern Political Economics sings the praises of Karl Marx for uncovering the source of profits in the exploitation of wage labor. Marx showed that human labor is not reducible to an ordinary commodity; workers rebel against their exploitation. However, the authors fail to develop this idea (and neither Adler nor Orrell talk about worker organizing at all). Instead, they devote too many words about how Marx succumbed to the “inherent error,” of using the labor theory of value to explain relative prices, giving rise to the infamous “transformation problem.” They imply that Marx’s failure here is one reason why his truths about profits and labor have been lost. This is much too simple. Marx’s truths have been lost because the class struggle waged by the working class has not succeeded in effectively challenging the rule of capital. Neoclassical economics is the economics of capital, as Marx’s political economy is that of the working class. As long as capital rules without a radical presence fighting against it, neoclassical economics will rule as well. No such presence exists today in any rich capitalist country, or, with a handful of exceptions, in any poor nation, either.
All three of these books are useful. Orrell makes sound recommendations that economists utilize methods of analysis and techniques that have proven their worth in other fields of study. His ten economic myths should be committed to memory. Adler has done a marvelous job of showing us, especially students, that neoclassical economics is strong on assertions but weak on supporting evidence. Varoufakis, Halevi, and Theocaratis have blown neoclassical economics to bits. However, stating the obvious stupidities and shortcomings of neoclassical economics will do nothing to weaken its hold. Unless, that is, a significant number of students and economists ally themselves with working men and women: teaching them, writing for and with them, becoming one of them in their own workplaces.
