Hayes on Keynes worksheet

This is a review of another book on Keynesian economics just published. It is found on the SHOE list. The review is below, and below it are some idiocies that really are modern beliefs about Keynes that are fore square wrong however common they may be. The bits in bold are my own highlights.

M. G. Hayes, John Maynard Keynes. Cambridge, UK: Polity Press, 2020. xv + 195 pp. $25 (paperback), ISBN: 978-1-5095-2825-7.

Mark Gerard Hayes, formerly of Robinson College, Cambridge, was a post-Keynesian economist who committed his academic life to the study of John Maynard Keynes. In his preface to John Maynard Keynes, Hayes reminisces that his over forty-year study of Keynes eclipses the time Keynes spent in his own scholastic pursuits.

Having invested an effective lifetime to become one of the trusted expositors of Keynes’s economics, it’s hard to imagine someone better suited than Hayes to distilling the economics of Keynes to less than 170 pages (graphs and tables included, no less). Even so, as an analytical biography written for undergraduates with or without formal training in economics, Keynes is an ambitious project. Its primary object is not solely to introduce readers to Keynes, but, specifically, to reiterate Keynes’s critique of classical economics in accessible language. But, Hayes is a veritable authority on Keynes, and his many years of devotion to the subject materialize in a refusal to take shortcuts. It should come as no surprise, then, that the exposition is rigorous, and, for many undergraduates, unsparing.

I note here that reviewing this work through the lens of an academic and an instructor on Keynes offers too little scope. The value of Keynes is understood by its ability to inform its intended audience. Therefore, to fairly assess this book, I offer the following review with its target readership in mind.

Keynes sets out with a brief statement of purpose and summary of the book’s trajectory in the opening chapter. Hayes then delves into classical thought in the form of a corn model in Chapter 2. The core argument is familiar, although its representation may not be. Marginal products determine the respective rates of utilization and of remuneration of labor and capital as profit-maximizing farmers organize production under conditions of diminishing returns. Hayes then delves into classical thought in the form of a corn model , echoing the dubious “continuity thesis” implicit in The General Theory. In any case, this chapter will be tough going for students unacquainted with mainstream economics, but provides a necessary transition to Keynes’s mature thinking.

Chapter 3 naturally turns to The General Theory and offers a concise and careful exposition of the principle of effective demand. Keynes’s non-standard concept of demand as income expected from production is first defined in order to underscore two fundamental features absent in the classical model: the role of future expectations shaping present behavior and the monetary nature of economic activity.

Hayes’s unique approach to the principle of effective demand is well-suited for undergraduates due to his manner of making concrete what Keynes left as abstract. Two instances stand out. For one, Hayes takes Keynes literally by designating the short term as one day. This firmly places the argument in historical time, while also promoting greater conceptual clarity than conventional definitions of the short term admit.

What’s most instructive about Hayes’s approach, though, is his tripartite classification of business into employers, investors and dealers. Keynes’s aggregate demand-supply framework is a constant source of confusion due, in no small part, to its anti-Marshallian rendering of supply and demand in which business appears on both sides of the aggregate market. But Hayes’s expository device disentangles aggregate supply from aggregate demand by mapping employers onto the supply curve, and dealers and investors onto the demand curve. Further, dealers play the critical role in finding, or not, the point of effective demand. In a skillful delineation of the multiplier, dealers adjust their daily inventories by selling spot to meet the increasing consumer demand while buying forward to replenish inventories. Whether the point of effective demand is reached ultimately depends on the fulfillment of dealers’ medium-term expectations, which, as Hayes notes, is unlikely given the uncertainty of consumer demand.

Chapter 4 extends further into The General Theory by fixating on Say’s Law and hence the theory of interest. As in the preceding chapter, Hayes sets out again by fixing ideas. Saving is income not consumed; income is the money value of net output; and, in aggregate, saving takes the form of physical goods. As the rate of interest is the rate on loans of money, an assumption shared by both loanable-funds theorists and Keynes, and saving represents a physical quantity of goods, the rate of interest is a matter of the supply and demand of money.

Hayes addresses liquidity preference after an interlude into Keynes’s investment theory. Because of the interest-centric perspective adhered to, a result of an analytical narrative that puts Say’s Law into the foreground, investment serves as a mere backdrop to discuss liquidity preference. Hayes does briefly address fundamental uncertainty and its relation to investment decisions, but there’s no mention of the marginal efficiency of capital nor its relation to the rate of interest.

Perhaps more troublesome, though, and bearing in mind the intended audience, is that Hayes repeats Keynes’s inconsistent usage of “investor” in The General Theory to mean both buyer of newly produced capital assets and holder of money, debts and shares. This inconsistency engendered confusion among Keynes’s readers; to reproduce it in an introductory text comes off as negligent. It’s all the more unfortunate to find it in a chapter intended to reveal the confusion between money and saving.

Chapters 5 and 6 take as their theme Keynes’s “long struggle to escape from habitual modes of thought and expression,” and especially as this escape concerns monetary theory. Hayes moves swiftly through technical aspects from A Tract on Monetary Reform and A Treatise on Money. Allusions to recent financial events enliven the prose and interrupt the brisk pace of Hayes’s analytical exposition to give the reader an appreciated respite. Still, these chapters, and especially Chapter 5, beset the reader with a kind of textual vertigo. Hayes juxtaposes Keynes’s early work against The General Theory, while enduring ideas (e.g., on the nature of money as debt) are interspersed between the two. These deficiencies don’t detract from Hayes’s extension of the principle of effective demand into the international sphere in Chapter 6, which deserves praise.

The book’s final two chapters assess Keynes’s legacy. Free from the burdens of crafting an analytical narrative, these final chapters establish an organic flow. Chapter 7 begins with a statistical comparison of the “Keynesian Era,” roughly the years 1951-1973, against other historical periods. Despite Hayes’s penchant for statistical inference on the basis of descriptive statistics, his broad-brush comparisons nicely segue to a consideration of how Keynesian was Keynes. Keynes’s policy positions, as borne out by the textual evidence, are then compared to his subsequent followers. Would Keynes be an advocate of Modern Money Theory and support a job guarantee program for developed countries? Almost certainly not. Keynes agrees with post-Keynesians that monetary policy is a rather ineffective instrument to manage the economy, right? No. Keynes’s primary policy proposal was to keep long-term rates low to encourage private and public investment. Linking Keynes’s thoughts on policy to current debates will no doubt interest those navigating today’s landscape.

Chapter 8 continues to dispel popularly-held beliefs on Keynes’s thinking. Hayes deflates the most pervasive myth of Keynes as the figurehead of lavish, even reckless, government spending programs. The unappreciated nuance concerns the ends to which government borrows. While increased borrowing for consumption is likely inevitable during recession, these deficits should be recovered over the course of the upswing. For Keynes, there is no permanent role for government consumption, in contrast to government investment.

The shortcomings I’ve cited relate almost exclusively to the disparity between the book’s elevated content and its targeted readership. Though easily digestible at times, I fear this book is beyond the grasp of undergraduates without training in economics. It will draw interest from dedicated neophytes, advanced students and academics looking for a concise and honest appraisal of Keynes’s work. Indeed, unlike other treatments that reveal more about their authors than the subject (Hyman Minsky’s John Maynard Keynes comes to mind), Hayes’s faithfulness to Keynes’s economics may well irritate some post-Keynesians for its, at times, conservative tone; while intriguing New Keynesians and others to notice that their concerns and positions on critical policy matters share a likeness with Keynes’s.

With his final work, Hayes confronted the onerous task of consolidating an encyclopedia of knowledge. But his passion for the subject cannot be abridged. While Hayes’s Keynes marks an end to a life of dedicated scholarship, in turn, it may mark the beginning for its readers.

 

These are specifics that I have highlighted.

The highlighted bits are from the review and below in unbolded type are my own comments.

Hayes then delves into classical thought in the form of a corn model.

Does anyone seriously believe that when Keynes was writing The General Theory that the economists he was dealing with were framing their arguments about anything at all on a corn model of growth and distribution?

 

Chapter 4 extends further into The General Theory by fixating on Say’s Law and hence the theory of interest.

If one is specifically intending never to understand the slightest thing about Say’s Law, focusing on the theory on interest is about as good a way to do it as one might find.

 

Keynes’s non-standard concept of demand as income expected from production is first defined in order to underscore two fundamental features absent in the classical model: the role of future expectations shaping present behavior and the monetary nature of economic activity.

Both of those supposed absences are not absent at all. Of course, if he never goes past Ricardo, then he would not know it. Is it possible to believe that classical economists saw no role for future expectations in shaping present behavior or that economic activity was affected by monetary factors. If you believe that, you are as ignorant as it is possible to be about the history of economic theory.

 

Saving is income not consumed; income is the money value of net output; and, in aggregate, saving takes the form of physical goods. As the rate of interest is the rate on loans of money, an assumption shared by both loanable-funds theorists and Keynes, and saving represents a physical quantity of goods, the rate of interest is a matter of the supply and demand of money.

That “saving represents “a physical quantity of goods” is absolutely correct since it is a definition. It is also the only sound way to conceive of saving since an economy is a process that allocates all of the productive resources in existence within an economy to their highest valued uses. By recognising at the same time that the rate of interest is a matter of the supply and demand for money is precisely the way in which all classical economists looked at the process of saving and investment. This is Wicksell and not Keynes (1936), although it is Keynes (1930).

 

Keynes’s primary policy proposal was to keep long-term rates low to encourage private and public investment.

In saving Keynes’s reputation he has to abandon what Keynes himself wrote. Nothing to do with public spending or short-term deficits. Over the side goes Can Lloyd George Do It? (1930).

 

Hayes deflates the most pervasive myth of Keynes as the figurehead of lavish, even reckless, government spending programs. The unappreciated nuance concerns the ends to which government borrows.

It was Keynes who wrote how fortunate the Egyptians had been in having pyramids to build or for the mediaeval economies to have been blessed with the construction of cathedrals. It was Keynes who suggested burying bank notes and then have them excavated to create jobs. Certainly not permanent spending on waste, but while the recession was on and while it was deep, Keynes certainly advocated all of that.

 

For Keynes, there is no permanent role for government consumption, in contrast to government investment.

There was no role for permanent government investment either. When at full employment, as Keynes wrote, classical principles would prevail.

 

Only supply constitutes demand

Other than straight out socialist plunder, no better way to comprehensively ruin an economy is to think public spending and monetary expansion can raise living standards and promote employment growth. Here’s an article by Richard Salsman published at The Hill in the US that tries to point out just that: Fiscal-monetary ‘stimulus’ is depressive.

Politicians, policy wonks and pundits like to classify as economic “stimulus” the $6 trillion in recent deficit spending and Federal Reserve money creation. But subsidies for the jobless, bailouts of the illiquid and pork for cronies are purely political schemes — and they depress the economy.

What is the case for “stimulus”? Many economists believe public spending and money issuance create wealth or purchasing power. Not so. Our only means of obtaining real goods and services is from wealth creation — production. Under barter no one comes to market expecting to buy stuff without also offering stuff. A monetary economy does not alter this key principle. What we spend must come from income, which itself must come from producing. Say’s Law teaches that only supply constitutes demand; we must produce before we demand, spend or consume. Demand is not a mere desire to spend but desire plus purchasing power.

Believers in “stimulus” also claim that government spending entails a magical “multiplier” effect on aggregate output, unlike most private sector spending. They tout a government’s greater “propensity to consume.” But consuming is the opposite of producing. Welfare states certainly consume and redistribute wealth. They divide it up. But math teaches that nothing – wealth included – can be multiplied by division. The so-called “multipliers” imagined by today’s economists are, in fact, divisors. Many studies have verified the principle.

It should become a pre-req for anyone to become a political leader to have successfully run a business for at least five years. Speaking of which I must also say how much I loved Tafkas’ post today.

A supply-side take on the PM’s package

I have to say that I have been charmed by the approach taken by the Government to bring us out of the lockdown. I find this especially extraordinary:

Value created by establishing successful products and services, the ability to be able to sell them at a competitive and profitable price and into growing and sustainable markets. It’s economics 101.

Here’s the thing. It is not Economics 101 and has not been for two generations. It ought to be, but isn’t. Because this is an entirely supply-side statement. There is not an ounce of C+I+G anywhere to be seen. It is entirely about Value Adding as the absolutely necessary core for regenerating growth.

Keynesian economics may really be dead, and not a moment too soon.

Suppose I hadn’t left Canada and moved to Australia

This is one of my potential alter-egos. It is Bob Bossin, who I remember from my days at the University of Toronto and in whose wider – much wider – circles I travelled. An enchanting fellow but the gravitational pull of all of my then associates would have made my own political migration much more difficult if not actually impossible. This is his Wikipedia page. A genuine banjo player who made a career of it. His warmth and charm comes across in the vid. I wish him well personally, but not politically.

What is also interesting to contemplate is that had he come to Australia as I did, he might have ended up a supporter of Donald Trump. Life is funny like that.

Might add that the Greens won the by-election.

“The best way to destroy the capitalist system is to debauch the currency”

Can you guess who said that?

Something that I have focused on in my Classical Economic Theory and the Modern Economy, but which is an otherwise unknown consequence of the Keynesian Revolution, was the shift in emphasis from the real side of the economy to the monetary side. If one is to understand the operation of an economy it is essential firstly to look at the actual real level of activity and only then look at the monetary side that lies above it and largely outside of it. Every classical economist understood the point. Virtually no modern economist does, and certainly no one without a serious study of economics ever does, which really does mean that near enough no one at all any longer understands this even slightly. Which leads me to this: Pandemic moves Modern Monetary Theory from the fringes to actual US policy.

[Modern Monetary Theory (MMT)] has received increased publicity over the past three years as politicians realized there was not a plausible plan to raise the funds necessary to fund “Healthcare for All,” the “Green New Deal,” free college and other initiatives through taxes alone.

The core principle of MMT is that sovereign governments with sovereign currencies can “print” or “coin” money to support full employment or essentially any government program that would benefit society in the here and now. Critics have labeled it the “Magic Money Tree Theory.” Those detractors include Keynesian and Monetarist economists, who cite Hungary in the 1840′s, Brazil in the 80′s, Mexico in the 90′s as examples of where easy money policies led to hyperinflation.

Warren Mosler was one of the founders of MMT, and what is known as `Mosler’s law’ states: “No financial crisis is so deep that a sufficiently large increase in public spending cannot deal with it.” These words fundamentally represent the actions our policy makers have taken in response to the virus. This pandemic has moved MMT from the fringes to the dead center as the actual monetary policy of the United States.

These are people with PhDs in economics who will comprehensively ruin us, and on this let me quote Keynes with absolute approval:

Lenin is said to have declared that the best way to destroy the capitalist system was to debauch the currency. By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens. By this method they not only confiscate, but they confiscate arbitrarily; and, while the process impoverishes many, it actually enriches some. The sight of this arbitrary rearrangement of riches strikes not only at security but [also] at confidence in the equity of the existing distribution of wealth….

As the inflation proceeds and the real value of the currency fluctuates wildly from month to month, all permanent relations between debtors and creditors, which form the ultimate foundation of capitalism, become so utterly disordered as to be almost meaningless; and the process of wealth-getting degenerates into a gamble and a lottery.

Lenin was certainly right. There is no subtler, no surer means of overturning the existing basis of society than to debauch the currency. The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner which not one man in a million is able to diagnose.

It was Lenin who said it, but quoted by Keynes as a warning to us all. Are you that one in a million who sees the point? Well if you are, there are then the other 999,999 who do not, which includes every single political leader heading every single government across the Western world today, each one of whom is engaging “all the hidden forces of economic law on the side of destruction”.

The price of ignorance

The History of Economic Thought is far and away the most interesting part of economics. Unlike the history of other disciplines, the history of chemistry for example, it can only be studied by someone with an economics background, but is also a very good medium through which to learn economics itself. And with modern economics courses drenched in junk science, HET is perhaps the only way to learn about how an economy works. A couple of days ago, the moderator at the Societies for the History of Economics (the SHOE list) put up a brief note:

Here is a second review of Zachary Carter’s The Price of Peace: Money, Democracy, and the Life of John Maynard Keynes, in The New York Times from Jennifer Szalai [the first one was from the WSJ]. This reviewer says it is “outstanding” and “brilliantly incisive.”

Which led me to this reply:

I am grateful again to the moderator for putting up another review of The Price of Peace, subtitled, “Money, Democracy and the Life of John Maynard Keynes. The review was from The New York Times. Its title, “John Maynard Keynes Died in 1946. An Outstanding New Biography Shows Him Relevant Still”. More of the usual mythology.

“The General Theory” aside, the rough outline of the Keynes story is that nobody with any power listened to his visionary proposals before the crisis of the Depression hit; after that, almost everyone did. Keynes’s ideas were radical, Carter writes, but he was staunchly anti-revolutionary: Having been traumatized by World War I, Keynes was at pains to persuade some of his Marxist students at Cambridge that a more just and equitable society didn’t have to come at the point of a gun. An activist government and deficit spending could alleviate suffering and spur growth, he reasoned, and the world eventually obliged. As much as Franklin Roosevelt didn’t like running a deficit, his New Deal offered one version of how Keynesianism worked; World War II offered another.

Of course, Harry Truman offered a third version on how things should be done. At the end of World War II, Truman immediately “sacked” all of the millions who had been in the armed forces while virtually the entire armaments industry was closing, thus creating perhaps the largest potential increase in mass unemployment in history. At the same time, and immediately the war was over, Truman balanced the budget, eliminating the largest deficit as a proportion of GDP in American history. And the result, as we all know, was the largest and most sustained period of growth in history with full employment continuing almost year after year through until the 1970s.

I might contrast The Price of Peace and its review with this: The Politics of Fear, whose sub-title is, “For economist Robert Higgs, Covid-19 is just the latest emergency justifying expanded government power”. Lots there to ponder, but will merely quote this:

“I foresee the worst depression since the Great Depression right around the corner. That alone would be enough to bring forth a host of bad government policies with long-lasting consequences. Many such policies have already been adopted. But much more awaits us along these lines.”

There have been so many breakages in the way our economies knit together in the past few months there is nothing that might not yet happen, and there is no telling how bad it might get. We are so far beyond anything that Keynes ever wrote about or dealt with that calling up his name is more than just a total irrelevance, it is an astonishing distraction. Yet the reviewer writes, in her very first paragraph, that this new biography of Keynes “offers a resonant guide to our current moment, even if he finished writing it in the time before Covid-19”.

Does it no longer occur to most economists to leave things to the market to sort themselves out? With Keynesian economics we are not only fighting the last war, we are fighting a war that had ceased in 1933 when the Great Depression ended (everywhere, it might be noted but in FDR’s USA), using classical economic theory to bring the Depression to an end. How inappropriate would Keynesian theory be in trying to deal with problems associated with our present government-engineered downturn that cannot in any sense be attributed to a deficiency of aggregate demand and an excess of saving.

The moderator has now added this:

To avoid any potential confusion, I just want to say that I posted these two reviews to point out that this bio of Keynes is getting a great deal of mainstream attention. It’s nice to see the history of economic thought in the WSJ and NYT. I have not read it and I do not have an opinion on it.

I thank Steve for his view and if any of our many other SHOE experts on Keynes has a reaction to the book, I hope they will share it with us.

There are 1200 who link into the SHOE list. Will let you know if anyone does.

Say’s Law and economic revival

Here’s an article worth your time: There Will Be No Recovery Without Production. To understand what needs to be done to get recovery going, you need to start with Say’s Law. Or as Richard Eberling puts it, you need to understand that ‘Our Ability to “Demand” Arises from Our Capacities to “Supply”’. This is from the text:

What the government lockdown policy response to the coronavirus has highlighted is the fundamental and inescapable truth of what the 19th French economist, Jean-Baptiste Say (1767-1832), called “the law of markets.” Contrary to the reawakened Keynesian mindset that all of our economic troubles are “aggregate demand failures” arising from a lack of spending due to people not having enough money in their pockets, the dramatic collapse in production, the massive rise in unemployment, and the falling off in people’s spending on final goods and services are all due to governments shutting down the “supply-side” of the economy.

As Jean-Baptiste Say, and those who followed his reasoning, argued, there is always work to be done, since there are always human wants that are as yet not fully satisfied; and as soon as one such human want has been significantly fulfilled to one degree or another, the human mind looks ahead and imagines other things that seem attractive and desirable to have. As a result, work merely of different sorts is there to be taken up in even greater amounts.

People may satisfy their wants and desires in one of two ways, Say explained. They may directly work and produce the goods they want for their own purposes. Few of our desires, however, can be fulfilled through our own personal efforts. So, the other way is to work and produce something that others might consider worth buying from us in exchange for what they can offer in trade; that is, goods that we want that either we do not have the ability to make for ourselves or only at higher costs than at which that potential trading partner can sell them to us.

There was then this I came across a couple of weeks ago: The COVID Stimulus is the Government’s Latest Rejection of Say’s Law. This is the final para:

Say’s timeless contribution to economics reveals that no matter what levers are pulled by the fiscal and monetary authorities, stones will not be turned into bread. The longer this economic shutdown lasts, the more critical it becomes to end it.

All this lost economic knowledge, available only on the fringes. The point is, if you hear any political leader discussing the need for an economic stimulus consisting of increased public spending, however bad things have been so far, you ain’t seen nothing yet.

Keynes, laissez-faire and coming out of lockdown

This was put up at the Societies for the History of Economics discussion thread:

The Wall Street Journal has a review by Ben Steil of Zachary Carter’s upcoming book, The Price of Peace: Money, Democracy, and the Life of John Maynard Keynes:

https://www.wsj.com/articles/the-price-of-peace-review-the-economic-engineer-11588947478

The review is behind a paywall, but I thought many on this list would be interested and would have access to it through a library or other provider.

And behind a paywall it remains, so this is all I could read, but it was quite enough:

“The more troublous the times, the worse does a laissez-faire system work.” Spoken in London in 1923, these words, among the lesser known of the most quotable economist of the 20th century, are perhaps his most important for these, our most troublous of times. For it is now, in the midst of a global pandemic the likes of which we have not seen since 1918, that the importance to life and livelihood of bold, informed and competent government becomes apparent. And no one wrote as originally and forcefully about what such a government does, faced with the prospect of economic collapse, than did John Maynard Keynes.

So let me draw your attention to a pamphlet published in 1926 by that self-same John Maynard Keynes: The End of Laissez-Faire where we find this passage:

From the time of John Stuart Mill, economists of authority have been in strong reaction against all such ideas. ‘Scarcely a single English economist of repute’, as Professor Cannan has expressed it, ‘will join in a frontal attack upon Socialism in general,’ though, as he also adds, ‘nearly every economist, whether of repute or not, is always ready to pick holes in most socialistic proposals’. (Theories of Production and Distribution, p. 494). Economists no longer have any link with the theological or political philosophies out of which the dogma of social harmony was born, and their scientific analysis leads them to no such conclusions.

Cairnes, in the introductory lecture on ‘Political Economy and Laissez-faire’, which he delivered at University College, London, in 1870, was perhaps the first orthodox economist to deliver a frontal attack upon laissez-faire in general. ‘The maxim of laissez-faire’, he declared, ‘has no scientific basis whatever, but is at best a mere handy rule of practice.’

I have noted before that the least understood grouping of economists in history are the later-classical economists from John Stuart Mill through to the end of the nineteenth century, from around 1848 with the publication of Mill’s Principles of Political Economy till around 1890 with the publication of Marshall’s Principles of Economics. I will just mention here that I hope to have at least in part remedied this major deficiency with a book that will be published by Elgar in June, Classical Economic Theory and the Modern Economy [https://www.e-elgar.com/shop/gbp/classical-economic-theory-and-the-modern-economy-9781786433565.html ]. That an economist can still get away with suggesting that economic theory prior to Keynes was rife with notions of laissez-faire shows so little awareness of the history of economics even among historians of economics is a scandal.

Just to focus on Mill, his Principles runs for almost 1000 pages, with the last 200 on the role of government, at the end of which he declares that the role is so extensive and the circumstances of the world so diverse, that even after those 200 pages he could not cover everything a government might find itself in need of doing so that no definitive limitations can be introduced. The only addition to the scope of economic policy introduced by Keynes was the notion of demand deficiency and with it the utility of public spending during recessions to lower unemployment, a policy universally opposed by classical economists but almost universally endorsed today. The historical record since the publication of The General Theory seems to show that the classics were completely right on that score. I cannot think of a single thing written by Keynes that would provide the slightest insight into how to bring our economies out of the lockdowns we have all experienced across the world.

I will also add that I have read the whole review and I will let you judge the book by this one quote from the review:

Mr. Carter seems to believe that Keynes, were he alive today, would be advising Sen. Bernie Sanders. But if we want to know what Keynes would do, we cannot simply extrapolate from his most radical writings.

If it is not immediately obvious how off the planet such an observation is, then I cannot help you further. Nothing I have ever written on Keynes is as discrediting as those words, since Keynes, if nothing else, was a serious scholar who tried to make sense of how an economy worked from a small-l liberal, that is from a classical liberal perspective. I believe he was wrong in his economic theories, but I would never have placed Keynes on the far left of the political spectrum, not only in his own time, never mind today.

HERE IS THE FULL REVIEW FROM THE WSJ:

The Price of Peace
By Zachary D. Carter
Random House, 628 pages, $35

“The more troublous the times, the worse does a laissez-faire system work.” Spoken in London in 1923, these words, among the lesser known of the most quotable economist of the 20th century, are perhaps his most important for these, our most troublous of times. For it is now, in the midst of a global pandemic the likes of which we have not seen since 1918, that the importance to life and livelihood of bold, informed and competent government becomes apparent. And no one wrote as originally and forcefully about what such a government does, faced with the prospect of economic collapse, than did John Maynard Keynes.

With the U.S. Congress having authorized $3.5 trillion in new spending over the past five weeks, it is tempting simply to conclude that we are all Keynesians now. Yet Keynes was hardly the crude advocate of deficit spending that he is too often made out to be. His writings on how to pay for World War II, and how Britain could avoid financial dependence on the U.S. in its aftermath, for example, reflect the careful workings of a brilliant and subtle mind, with the fullest appreciation for detail and circumstance. Were Keynes alive today, he would have much to say not just about what to spend on what but about how to manage the financial burden efficiently and fairly.

Timing, paradoxically, can be critical to a history book, and “The Price of Peace: Money, Democracy, and the Life of John Maynard Keynes” couldn’t have appeared at a more opportune moment. Journalist Zachary Carter has crafted a timely, lucid and compelling portrait of a man whose enduring relevance is always heightened when crisis strikes. If there is a conspicuous blemish in the book, it is the polemical turn of its last third, which goes well beyond the life of his subject. Still, readers of all political persuasions will, in the biographical material at least, find plenty of insight for our time.

As Mr. Carter makes clear, Keynes’s life mission was to find the keys to sustaining democracy and economic liberty in the face of challenges from authoritarians of the left and the right—and not when times were easy but when they were most troublous. Now, with economies around the world struggling to emerge from a devastating, unprecedented shutdown, we who have been blessed to live in liberty will need to reflect on what will be needed to preserve it once the present crisis passes (assuming we are wise enough to surmount it).

Like it or loathe it, we are not going back to globalization as we knew it—the globalization that emerged with the rise of China and the internet after the end of the Cold War. Five years after the end of World War I and the start of the Spanish flu epidemic, Keynes was similarly aware that Britons were not going back to the glorious globalization of the late 19th century and the heyday of the British Empire. The task as he saw it, then, was to create a less glorious but more durable regime.

Born in Cambridge in 1883, Keynes had followed in the footsteps of his academic parents, securing, at age 26, a prestigious life fellowship at Cambridge’s King’s College. There he was regarded with awe by some of the greatest minds of the early 20th century. “Keynes’s intellect was the sharpest and clearest that I have ever known,” wrote Bertrand Russell. “When I argued with him, I felt I took my life in my hands.”

Keynes did not, however, make his name as a scholar until relatively late in life. He published his first major economics work (“A Tract on Monetary Reform”) in 1923, at age 40. He initially came to prominence as a British government financial adviser during World War I, accompanying Prime Minister David Lloyd George to the Paris peace talks. His scathing account of those talks (“The Economic Consequences of the Peace”) and his premonitions of political disaster to come, however, instantly transformed him into a major public intellectual. Mr. Carter ably weaves the narrative of Keynes’s personal life—his association with the Bloomsbury set, his male relationships before marrying a Russian ballerina in 1925—into that of his rise to professional fame during these years.

It is as an economic thinker, of course, that we primarily know Keynes today. Yet Keynes, a polymath with an abiding interest in philosophy, art and politics, would have had difficulty even gaining admission into today’s math-obsessed Ph.D. programs. Though an able mathematician himself, he had only disdain for those who sought precise solutions to big, imprecise problems. As an economics major in college, I learned “Keynesian” methods, yet was never asked to read Keynes. Those methods had been formulated by later American disciples and would mostly have been dismissed by the master as misleading and factitious.

It is difficult to overstate the effect that Keynes’s 1936 masterwork, “The General Theory of Employment, Interest and Money,” had on the economics profession, particularly in the U.S. The book—his effort to unearth the deeper causes of, and solutions to, Britain’s stubbornly high unemployment—virtually established macroeconomics as a discipline, both in the academy and in government. But the unusual style of “The General Theory” made it hard for even expert readers to separate out its “true” substance. It is only slightly outlandish to liken this work to the Bible. It is full of memorable, mellifluous passages. It is also, at times, obscure, tedious and tendentious. It is a work of passion driven by intuition, with tenuous logic and observation offered as placeholders until faithful adherents could unearth the proofs.

The central contention of “The General Theory” was revolutionary (at least to economists): that the economy had no natural tendency toward full employment. If governments did not intervene forcefully to boost consumption demand, Keynes argued, high unemployment could persist indefinitely. Cheap money provided by the central bank would not suffice to alter the circumstances decisively. This contention was wholly contrary to classical economics, which held that protracted involuntary unemployment was a result of some interference in the workings of the price mechanism. In classical economics, full employment required flexible wages; Keynes showed why, with different assumptions, falling wages could actually worsen unemployment. These different assumptions were related to the nature of money, to human psychology and to the conventions of contemporary society. Each of these on its own would do to support Keynes’s argument, and he was not that particular about which he credited at any time.

There is also much contradiction in Keynes’s thought, and between his thought and his behavior—contradiction that provides endless opportunity for fans to claim him as their own, or for detractors to dismiss him entirely. He was “too mercurial and impulsive a counsellor for a great emergency,” groused Lloyd George. “He dashed at conclusions with acrobatic ease [and] rushed into opposite conclusions with the same agility.” He eagerly speculated in securities, for himself and his college, particularly abroad, while calling for a policy to limit speculating in securities, particularly abroad. He further expressed biting disdain for those who supported both the orthodoxies and the heresies he himself had espoused in earlier times.

Yet it was not fickleness but a keen sensitivity to political contexts that typically drove Keynes’s shifts in economic thought. “When the facts change,” he famously told a critic of his volatile views on monetary policy, “I change my mind. What do you do, sir?” Unusually for an economist, he took the shifting mores of society seriously when prescribing policy and didn’t seek to mold humanity to his models or preferences. He was also more an internationalist Englishman than an English internationalist, so that the trajectory of his thinking tracked the trials and tribulations of his country as it struggled, from 1914 to his death in 1946, with war, inflation, deflation, unemployment, indebtedness and the growing demands of the masses for greater voice and security.

As a government adviser and diplomat, he was perspicacious and farsighted, yet rarely converted an intellectual adversary. In Washington, where he represented the U.K. during both world wars, he was all too often “dogmatic and disobliging,” making “a terrible impression for his rudeness”—and this according to his own British colleague. At the 44-nation Bretton Woods conference in 1944, which established the International Monetary Fund, the World Bank and the dollar-based global monetary system, he became the first celebrity economist, captivating the American press—yet infuriating the U.S. Treasury, which sidelined and outmaneuvered him. It is a testament to the influence of Keynes’s ideas, however, that so many policy thinkers around the world still want to create a legitimate supranational currency, modeled after his “bancor” proposal at Bretton Woods, to supplant the international role of the dollar.

Robert Skidelsky’s renowned biography of Keynes ran to three volumes, the last of which was published in 2001. As Mr. Carter notes in his acknowledgments, “all modern Keynes scholars begin their journey” from this foundational work. But wholly apart from his auspicious timing, Mr. Carter has, with this fresh reappraisal, made an outstanding authorial debut. The financial and economic questions with which Keynes wrestled, both as scholar and adviser, were complex, and it is tempting for an author writing for a wide audience to gloss superficially over the more difficult ones. But whether the subject is war reparations or interest-rate policy, Mr. Carter leaves no reader behind, and he writes with wit and clarity. Capturing in a single sentence why Keynes persisted with abstruse theoretical writing long after becoming a major public intellectual, Mr. Carter explains that “if Keynes wanted to reach the sovereigns, he would first have to convert the priesthood.” Keynes had set out to change the very foundations of economic policy-making. And to do that he had to change economists themselves. By any reasonable measure, he succeeded.

This book covers considerably more than the life and labors of his subject, however. Keynes expires on page 368, but his legacy, or Mr. Carter’s version of it, carries on for a further 166 pages. For this reader, at least, the later material constitutes a mixed blessing. Mr. Carter nicely narrates the story of the bitter and consequential split between the “left” Keynesians, led by Joan Robinson in Britain and John Kenneth Galbraith in the U.S., and the “right” Keynesians, led by Paul Samuelson and his fellow mathematical economists. But Keynes and Keynesianism disappear for long stretches of text, as the discussion devolves into an ever-angrier assault on “neoliberal” trade and market-liberalization policies, which Mr. Carter blames for growing inequality. The author reserves his harshest treatment for Democrats, with Bill Clinton bearing the brunt of his wrath for championing the North American Free Trade Agreement, the World Trade Organization and greater economic ties with China.

Mr. Carter seems to believe that Keynes, were he alive today, would be advising Sen. Bernie Sanders. But if we want to know what Keynes would do, we cannot simply extrapolate from his most radical writings. Keynes as diplomat—at Bretton Woods and in Washington the year following, begging for a loan—didn’t choose splendid isolation. Instead, he adapted his policy positions to the reality of America’s rise to economic dominance, however repugnant he found it. He would, today, surely not spit into the winds gusting from a rising China. He would get his country the best deal he could, understanding that China was going to reshape the world, peacefully or otherwise, with or without his cooperation. Mr. Carter himself, in the end, believes that Washington should engage in “cooperative economic diplomacy.” But what was China’s WTO accession if not “cooperative economic diplomacy”?

Mr. Carter is also too dismissive of contributions to economic policy thinking from the center and the right, particularly from Nobel Prize winners Friedrich Hayek and Milton Friedman—both of whom he paints, in his more charitable moments, as tools of reactionary and moneyed interests. During the present economic crisis—as during the financial crisis a decade ago—unprecedentedly bold monetary interventions have been more important in preventing economic collapse than fiscal ones. And it was Friedman’s analysis, not Keynes’s, that stimulated this reaction from the Fed and other central banks. It was Friedman to whom Ben Bernanke, the former Fed chair (and Great Depression scholar) paid homage for his seminal analysis of the monetary causes of the Depression and to Friedman’s work that Bernanke turned for guidance when faced with the challenge of preventing another one. Current Fed Chairman Jay Powell is following the same script, but with even more gusto.

In the end, readers who admire the anti-“market fundamentalism” of Nobel economist Joseph Stiglitz, whom Mr. Carter quotes approvingly, will delight in this book’s extended epilogue; those who don’t, won’t. In any case, Mr. Carter might have been wiser to write two books, letting his fine and eloquent analysis of Keynes’s life and thought stand alone as the best single-volume biography of this intellectual giant.

What would an historian of economics know about John Stuart Mill?

Classical Economic Theory and the Modern Economy

I posted the note below onto the Societies for the History of Economics website in regard to François Quesnay, an eighteenth century French economist, but it’s really about John Stuart Mill. No one has responded among the 1200 who are part of this website. Lots here that is scandalous to me, but the easy peasy way it is to demonstrate that at the very centre of the study of the history of economic thought, there is no one who has the slightest idea what Mill said about the theory of value which they nevertheless continue to ridicule. This is part of the reason I wrote my Classical Economic Theory and the Modern Economy.

I found this, from Spencer Banzhaf, the most astonishing sentence I may have seen in quite some time, and I could not agree more.

“One cannot possibly discuss what happened to the role of agriculture/nature in value between Quesnay and today without talking about what happened to the meaning of “value,” conceived of as a moving target.  Rival theories of surplus value from Quesnay to Jevons will have to come into play.”

I often go on about the disastrous effect on economic theory of the Keynesian Revolution, but almost equally disastrous was the Marginal Revolution which undermined the classical theory of value, which was outlined comprehensively by John Stuart Mill in Book III Chapter VI of his Principles. Before I state my conclusion, I will just mention this, which comes from the brief profile of Mill that is on the HET website:

“John Stuart Mill’s greater economic performance was his magnificent 1848 Principles of Political Economy, a two-volume extended restatement of the Classical Ricardian theory.  He believed  Ricardo’s labor theory of value to be so conclusive that, in the beginning of a discussion on the theory of value, Mill confidently notes that:

‘Happily, there is nothing in the laws of Value which remains for the present or any future writer to clear up; the theory of the subject is complete: the only difficulty to be overcome is that of so stating it as to solve by anticipation the chief perplexities which occur in applying it.’ (J.S. Mill, Principles, 1848: Book III, Ch. 1).

“Thus putting a stone on the matter, and burying supply-and-demand theory for another quarter-century.  When Jevons’s later grumbled at the ‘noxious influence of authority’ preventing the development of economics, there is little doubt he was referring to J.S. Mill.”

That is all we think we know about the classical theory of value and it could not be more completely wrong. Mill did not restate “Classical Ricardian theory”. He explicitly discussed supply and demand. If you go to Mill, the first two of the seventeen elements in his theory of value are firstly, that the issue is not price as such, but relative prices, and then secondly, that the “temporary or market value” of something can be determined by supply and demand. There is no labour theory of value to be found anywhere. This is what Mill wrote:

“I. Value is a relative term. The value of a thing means the quantity of some other thing, or of things in general, which it exchanges for. The values of all things can never, therefore, rise or fall simultaneously. There is no such thing as a general rise or a general fall of values. Every rise of value supposes a fall, and every fall a rise.

II. The temporary or Market Value of a thing, depends on the demand and supply; rising as the demand rises, and falling as the supply rises. The demand, however, varies with the value, being generally greater when the thing is cheap than when it is dear; and the value always adjusts itself in such a manner, that the demand is equal to the supply.

The shallow reasoning and lack of depth in a modern textbook is a scandal, but is kept from most of us because no one knows what the economic theory of the past actually consisted of. If Spencer Banzhaf intends to be stating that “rival theories of value from Quesnay to Jevons” will need to be examined, then that is absolutely the case. What astonishes me is that both macro (which has replaced the classical theory of the cycle) and micro were much more profound among the later classical economists than amongst the majority of the economics profession today. We have more diagrams, they had a deeper understanding.

Mill and marginalism

A conversation based on John Stuart Mill and the theory of value.

PETER:

Obviously I don’t find this stuff as interesting as you do. But have just, admittedly quickly, looked at JSM’s theory of value. I can’t see how this stacks up: “almost equally disastrous [as the Keynesian Revolution] was the Marginal Revolution which undermined the classical theory of value”. Which of Mill’s 17 propositions does it undermine?

ME:

The Marginal Revolution starts with Marginal Utility. And let me mention that Mill was the greatest and most influential utilitarian philosopher in history, yet he absolutely refused to incorporate utility into his economic analysis, as noted here. The abstract begins:

“The concept of utility, which stood at the heart of J. S. Mill’s utilitarian moral philosophy, played only a minor role in his account of economics. The economic idea of (individual) utility, as is well known, neither inspired Mill directly nor excited his attention when developed in the work of other economists.”

And the reason in part, as discussed in my forthcoming book, was, and I argue from plenty of evidence, that the introduction of utility took the analytics of the economy from the supply side to the demand side. Lots of other things I could say and do say, but I hope this is enough for you to see my point. In my textbook I go into it in much more detail but do preserve cost-benefit analysis as part of what an economist needs to understand.

There are around 1200 economists on that website but I doubt any of them will want to buy into any of this and they are typically a fractious lot. Not that it’s the reason I bought into this query, but it did stoke my annoyance that it is the editor of our local journal, who want to dispose of the two papers, including mine, that he has held in his hands for two years, that asked the initial query which began thus:

My long message emerges from a series of papers I have received from a retired physicist, Kevin Wilks, who is 95 and argues (as physicists are wont to do) that laws of physics underlie economics, in this case production itself and the industrial structure. Economies capture energy and convert it into value (my summation). He draws on Quesnay and the primacy of agriculture, which I [is] why I write to SHOE for help, both to advise Kevin and to sort things out in my own head. And perhaps Kevin is onto something; if so, it is not straight HET, so what journals or outlets cater for speculative papers by intelligent amateur economists? The main concern here is not what Quesnay really said, but why what is valid in Quesnay is absent from textbooks. Wilks argues that introductory economics should locate the dependency of what we now call the secondary and tertiary sectors on the primary sector. Textbooks would be written differently. Of course, what is valid in a body of thought need not be regarded as important, but I press on.

This chap is a complete economic illiterate who thinks that economics should be reduced to energy flows – an old and idiotic economic concept that completely omits the notion of value and pricing. My article on Mill is however beyond his ken. Is it any wonder that economics has stagnated for the past hundred years, if not actually going backwards? Actually it has gone backwards, but who is this cretin to notice? This is why it is so difficult to get published when trying to say anything against modern textbook theory runs such obstacles as this. It’s only fortunate that I am now beyond the realm of publish or perish.

PETER:

Marginal utility is a demand concept for sure but I would have thought the fault which led to Keynes was the focus on demand as an aggregate not on demand per se.

ME:

Want more? Utility cannot be measured and in any case has nothing to do with relative prices, whereas the supply side of the economy and the cost structure of the economy is the way in which the resource base is allocated to different outputs.

No classical economist bought the marginal stuff in the English speaking world until Joan Robinson and Edward Chamberlain turned the concepts into diagrams.

And fwiw, marginal utility has disappeared from our texts and been replaced by indifference curves, which are just as useless, and also unmeasurable.

PLUS THIS:

And this from “The Physiocrats and Say’s Law of Markets”. I by Joseph J. Spengler.

The Physiocrats and Say’s Law of Markets. I
Author(s): Joseph J. Spengler
Source: Journal of Political Economy, Vol. 53, No. 3 (Sep., 1945), pp. 193-211

The physiocrats always expressed their theory of circular flow in interclass, rather than in interindividual, terms. Notwithstanding, their theory of circular flow forced upon them several conclusions of importance. They looked upon money as an instrument whose essential function it is to facilitate the circulation of goods and services, to serve as a medium of exchange. In consequence, they recognized that commerce consists, not in buying and selling, but in the exchange of goods and services for goods and services. They thus laid the ground work for the formulation of Say’s law of markets and evoked its actual statement by their treatment of consumption and expenditure. They recognized, too, that if money ceases to perform its function, the nexus between potential purchasers and potential sellers is broken, thus anticipating Keynes; but they did not develop this theory, for they supposed that in a healthy economy founded upon their principles money would always perform its proper function. (p. 205)

 
Notable here is that goods exchange for goods and the circular flow is in real terms with money facilitating the exchange. This is what Say himself would include in his Treatise in 1803. What Keynes did was recast the entire process into a circular flow of money forgetting to separate out and on their own the real exchanges that simultaneously occur. In a Keynesian model, and therefore in modern macro, the real half of the process is no longer distinguished and discussed.
