Anything We Can Do, We Can Afford

John Maynard Keynes, in a 1942 BBC address:

Let us not submit to the vile doctrine of the nineteenth century that every enterprise must justify itself in pounds, shillings and pence of cash income … Why should we not add in every substantial city the dignity of an ancient university or a European capital … an ample theater, a concert hall, a dance hall, a gallery, cafes, and so forth. Assuredly we can afford this and so much more. Anything we can actually do, we can afford. … We are immeasurably richer than our predecessors. Is it not evident that some sophistry, some fallacy, governs our collective action if we are forced to be so much meaner than they in the embellishments of life? …

Yet these must be only the trimmings on the more solid, urgent and necessary outgoings on housing the people, on reconstructing industry and transport and on replanning the environment of our daily life. Not only shall we come to possess these excellent things. With a big programme carried out at a regulated pace we can hope to keep employment good for many years to come. We shall, in fact, have built our New Jerusalem out of the labour which in our former vain folly we were keeping unused and unhappy in enforced idleness.

 (Collected Works XXVII)

Relevant today, obviously: Thirteen million people unemployed, 25 percent of industrial capacity idle, and capital, if the interest rate is any guide, more abundant than it’s been in decades. If our masters were only interested in what’s best for everyone, as they always claim, now would be the moment for new bridges, hospitals, subways, colleges, and public housing, and for parks, theaters, museums, and cafes. Not to mention wind farms. A recession isn’t the time to trim sails and take short views, it’s the time to go long. So let’s build that New Jerusalem.

Keynes Quote of the Day

From Britain’s Industrial Future:

The notion that the only way to get enough effort out of the brain-worker is to offer him unfettered opportunities of making an unlimited fortune is as baseless as the companion idea that the only way of getting enough effort out of the manual worker is to hold over him the perpetual threat of starvation and misery for himself and those he loves. It has never been even supposed to be true, at all events in England, of the soldier, the statesman, the civil servant, the teacher, the scientist, the technical expert.

And to think this was the Orange Book of 1928! Times have changed.

They sure have. Then, it seemed like the move away from institutions based on material incentives to institutions based on intrinsic motivation was well underway, or at least realizable. While today — perhaps in Britain even more than the US — the tide is running strong the other way, with the good and great eager to get teachers and technicians, if not yet soldiers and statesmen, onto the unlimited-fortune/starvation-and-misery plan.

The context of the quote is interesting, too — it’s part of a larger argument for the “more or less comprehensive socialization of investment” Keynes would continue to argue for in the General Theory. Since managers of private firms already work for “a certain salary, plus the hope of promotion or bonus,” nothing would change if their businesses were publicly owned: “The performance of functions by Public Concerns in place of privately owned Companies and Corporations would make but little difference to the ordinary man.” If soi-disant hard Keynesians read more Keynes, they would find a much more radical vision there than countercyclical fiscal policy.

(via Jim Crotty’s unpublished book on Keynes. Encouraging him to get that thing out is high up on my list of life goals. Britain’s Industrial Future was officially written by a committee of Liberal grandees headed by Lloyd George. But this passage was written by Keynes, Crotty says, and he would know.)

Post Keynesianism in Practice

From the FT the other day:

That Facebook is worth $50bn or Twitter $10bn, is recounted as fact. … But there are still precious few numbers to analyse and business models are no more proved than for dotcoms a decade ago.

To illustrate the ridiculousness of trying to value these things consider LinkedIn. Its S-1 registration statement (with US regulators) provides rudimentary financial statements from which to model the company. Revenues, operating costs, capital expenditure and depreciation and amortisation schedules are available for the past five years. It is then a hop to forecast earnings before interest, tax, depreciation and amortisation and, thus, future free cash flows. Discount these cash flows (made easier because there is no debt) and you’ve got a valuation.

But who on earth knows what forecasts to make? Private secondary markets supposedly value LinkedIn at $2.5bn-$3bn. To arrive at the bottom of that range requires sales to expand 60, 50 then 40 per cent over the next three years, before tailing off to a terminal growth rate of 3 per cent in 2019. Ebitda as a proportion of revenues has to double to 20 per cent and stay there. … If sales growth tapers off faster than expected or if systems spending becomes a bottomless pit, you can halve that valuation for starters. But what if LinkedIn’s platform easily copes with millions of new members? Double ebitda margins to 40 per cent and a $5bn company is easily within reach. Who knows? No wonder it’s easier to simply quote the same price tag as everyone else.

Fundamental or Knightian uncertainty tends to get treated as something airy-fairy, as part of the philosophy-of penumbra rather than economics per se. But as this example shows, it’s unavoidable in plenty of practical questions. Mainstream models avoid dealing with the problem by assuming that the true probability distribution of all possible future events is always known. But in the real world of business people aren’t so silly. As the man says:

The outstanding fact is the extreme precariousness of the basis of knowledge on which our estimates of prospective yield have to be made. Our knowledge of the factors which will govern the yield of an investment some years hence is usually very slight and often negligible. If we speak frankly, we have to admit that our basis of knowledge for estimating the yield ten years hence of a railway, a copper mine, a textile factory, the goodwill of a patent medicine, an Atlantic liner, a building in the City of London amounts to little and sometimes to nothing; or even five years hence. In fact, those who seriously attempt to make any such estimate are often so much in the minority that their behaviour does not govern the market. …

Investment based on genuine long-term expectation is so difficult to-day as to be scarcely practicable. He who attempts it must surely lead much more laborious days and run greater risks than he who tries to guess better than the crowd how the crowd will behave… It needs more intelligence to defeat the forces of time and our ignorance of the future than to beat the gun.

Economists might not believe in Keynes any more. But business journalists certainly seem to!

No More ZLB

Can we please stop talking about the zero lower bound?

Krugman today insists that we do, in fact, face a problem of inadequate demand. And he’s right! But he glosses this as an “excess supply of savings even at a zero interest rate,” which isn’t right at all.

Let’s be clear: There is not “an” interest rate, certainly not a zero one. There are various interest rates, and the ones that are relevant to saving and investment remain high. The BAA corporate bond rate (the red line in the figure below) is currently at 5.7 percent — pretty much exactly where it was in the first half of 2005. And given that inflation is substantially lower than it was five years ago, that particular real interest rate is not only not zero, it’s gone up.


The real question is, can reducing the federal funds rate reduce the economically important interest rates? Now, obviously the answer is No if the fed funds rate (the blue line in the graph) is as low as it can go; in this sense the ZLB is real. But the answer can also be No when the fed funds rate is well above zero, if there’s no reliable link between the overnight Treasury rate and the rates businesses borrow at; and that seems to have been the case since sometime in the ’90s. As the figure shows, the Fed’s recent rate reductions didn’t reduce bond rates at all, even before the Fed Funds rate hit zero; and all the hikes earlier in the decade didn’t raise bond rates either. You’d see a similar picture if you looked at any other economically relevant interest rate. In general, as my friend Hasan Comert shows in his just-defended dissertation, the Fed lost control of the important interest rates some time ago. So the best thing you can say for the zero lower bound, is that arriving there has dramatized a truth that should have been evident for some time already.

As usual, Keynes got it right: “The acuteness and the peculiarity of our contemporary problem arises out of the possibility that the average rate of interest which will allow a reasonable average level of employment is one so unacceptable to wealth-owners that it cannot be readily established merely by manipulating the quantity of money. … The most stable, and the least easily shifted, element in our contemporary economy has been hitherto, and may prove to be in future, the minimum rate of interest acceptable to the generality of wealth-owners.” The failure of interest rates to move to a level compatible with full employment is not a technical problem, but a structural one.

Those Who Forget History, Are Probably Historians

There are hardly any economists or economic historians who have contributed more to our understanding of the role of international finance in the Great Depression than Barry Eichengreen and Peter Temin. [1] So it’s disappointing to see them so strenuously refusing to learn from that history.

They start by correctly observing that the fatal flaw of the gold standard was the “asymmetry between countries with balance-of-payments deficits and surpluses. There was a penalty for running out of reserves .. but no penalty for accumulating gold.” Thus the structural tendency toward deflation in the gold standard era, and the instability of the system once workers recognized that lower wages for “sound money” wasn’t such a great deal. If Temin and Eichengreen want to draw a parallel with the Euro system today, well, I’m not sure I agree, but it’s an avenue worth pursuing. But as they want to apply it, to the US and China, it’s unambiguously wrong, as economics and as history.

“The point,” say Temin and Eichengreen, “is not to let deficit countries off the hook.” Barry, Peter — read your books! Letting the deficit countries off the hook is exactly the point. If there’s one lesson in Lessons from the Great Depression, it’s that no practical response to the crisis was possible until the idea that a trade deficit represented a kind of moral failing was abandoned. The whole point, first, of leaving the gold standard, and later, of the Bretton Woods institutions, was to free deficit countries from the obligation to “live within their means” by curtailing domestic investment and consumption.

Keynes couldn’t have been clearer on this. The goal of postwar monetary reform, he wrote, was “A system which would maintain balance of payments equilibrium without trade discrimination but also without forcing unemployment .. on deficit countries,” [2] in other words, a system in which governments’ efforts to pursue full employment was not constrained by the balance of payments. We needn’t take Keynes as holy writ, but if we’re going to analyze current arrangements in light of his writings in the 1940s, as Temin and Eichengreen claim to, we have to be clear about what he was aiming for.

One would expect, then, that they would go on to show how “global imbalances” are constraining national efforts to pursue full employment. But they don’t even try. Instead, they offer ambiguous phrases whose vagueness is a sign, perhaps, of a bad conscience: Keynes “wanted measures to deal with chronic surplus countries.” What kind of surpluses, exactly? and deal with how?

The beginning of wisdom here is the to recognize the distinction between the balance of payments and the current account. Keynes was concerned with the former, not the latter. Keynes didn’t care if some countries ran trade surpluses or deficits, temporarily or persistently; what he cared about was that these imbalances did not interfere with other countries’ freedom “to pursue full employment and progressive social policies.” In other words, current account imbalances were not a problem as long as the financial flows to finance them were guaranteed.

“Creditor adjustment” is rightly stressed by Eichengreen and Temin as a central feature of Keynes’ vision of postwar monetary arrangements, but they seem to have forgotten what it meant. It didn’t mean no one could run a trade surplus, it just meant that the surplus countries would be obliged to lend to the deficit ones as much as it took to finance the trade imbalances. As Keynes’ follower Roy Harrod put it,”The most important requirement [is] to get the United States committed to creditor adjustment. …. Creditor adjustment could be secured most simply by an agreement that the creditor would always accept cheques from the deficit countries in full discharge of their debts. … So long as their credit position cannot cause pressure elsewhere, there is no harm in allowing a further accumulation.” All of Keynes’ proposals at Bretton Woods were oriented toward committing the countries with surpluses to lend, at concessionary rates if necessary, to the deficit ones.

China today accepts American checks in full discharge of our debts; they don’t demand payment in gold. The Chinese surplus isn’t putting upward pressure on US interest rates, or constraining public spending. All Keynes ever wanted was for all surplus countries to be like China.

“Sixty-plus years later, we seem to have forgotten Keynes’ point,” Eichengreen and Temin conclude. True that.

What is Keynesianism?

[A bit of thumbsucking inspired by discussion here.]

As a policy of countercyclical demand management, Keynesianism is based on the idea that there are no automatic forces in industrial capitalism that reliably equilibrate aggregate supply and aggregate demand. In the absence of government stabilization policies, the economy will waver between inflationary periods of excess demand and depressed periods of inadequate demand. The main explanation for this instability is that private investment depends on long-term profitability expectations, but since aspects of the future relevant to profitability are fundamentally uncertain [1], these expectations are unanchored and conventional, inevitably subject to large collective shifts independent of current “fundamentals”. Government spending can stabilize demand if G+I varies less over the business cycle than I alone does. For which it’s sufficient that government spending be large. It’s even better if G and I move in opposite directions, but the reason Minsky answered No to Can “It” Happen Again? was because of big government as such, not countercyclical fiscal policy.The focus on cyclical stabilization assumes that there is no systematic long-term divergence between aggregate supply and aggregate demand. But Keynes believed that there was a secular tendency toward stagnation in advanced capitalist economies, so that maintaining full employment meant not just using public expenditure to stabilize private investment demand, but to incrementally replace it. Another way of looking at this is that the steady shift from small-scale to industrial production implies a growing weight of illiquid assets in the form of fixed capital. [2] There is not, however, any corresponding long-term increase in the demand of illiquid liabilities. If anything, the sociological patterns of capitalism point the other way, as industrial dynasties whose social existence was linked to particular enterprises have been steadily replaced by rentiers. [3] The whole line of financial innovations from the first joint-stock companies to the recent securitization boom have been attempts to bridge this gap. But this requires ever-deepening financialization, with all the social waste and instability that implies. It’s the government’s ability to issue liabilities backed by the whole economic output that makes it uniquely able to satisfy the demands of wealth-holders for liquid assets. In the functional finance tradition going back to Lerner, modern states do not possess a budget constraint in the same way households or firms do. Public borrowing has nothing to do with “funding” spending, it’s all about how much government debt the authorities want the banking system to hold. If the demand for safe, liquid assets rises secularly over time, so should government borrowing.From this point of view, one important source of the recent financial crisis was the surpluses of the 1990s, and insufficient borrowing by the US government in general. By restricting the supply of Treasuries, this excessive fiscal restraint spurred the creation of private sector substitutes purporting to offer similar liquidity properties, in the form of various asset-backed securities. (Here is a respectable mainstream guy making essentially this argument. [4]) But these new financial assets remained at bottom claims on specific illiquid real assets and their liquidity remained vulnerable to shifts in (expectations of) the value of those assets. The response to the crisis in 2008 then consists of the Fed retroactively correcting the undersupply of government liabilities by engaging in a wholesale swap of public for private liabilities, leaving banks (and liquidity-demanding wealth owners) holding government liabilities instead of private financial assets. The increase in public debt wasn’t an unfortunate side-effect of the solution to the financial crisis, it was the solution. Along the same lines, I sometimes wonder how much the huge proportion of government debt on bank balance sheets — 75 percent of assets in 1945 vs. 1.5 percent in 2005)contributed to the financial stability of the immediate postwar era. With that many safe assets sloshing around, it didn’t take financial engineering or speculative bubbles to convince banks to hold claims on fixed capital and housing. But as the supply of government debt has dwindled the inducements to hold other assets have had to grow increasingly garish. From which I conclude that ever-increasing government deficits may in fact be better Keynesianism – theoretically, historically and pragmatically – than countercyclical demand management.
[1] Davidson, Shackle, etc. would say nonergodic. This strand of Post Keynesian thinking often wanders beyond my comfort zone.[2] This shift is ongoing, not just historical — not only do capital-output ratios continue to rise in manufacturing, but we’re seeing the “industrialization” of retail, health care, etc.

[3] Schumpeter is the only major economist to give sufficient attention to the sociology of the capitalist class, IMO. Marx’s insistence that the capitalist is simply the human representative of capital is a powerful analytic tool for many purposes, but it leaves some important questions unasked.
