Ashoka Mody On The Euro Tragedy

Ashoka Mody has a fine article The Euro Area’s Deepening Political Divide on VoxEU on how recent national elections in Germany and Italy suggest that people of Europe are drifting apart.

He also gives a historical context to what voters think. For example, he says:

And in September 1992, the French public came within a whisker of rejecting the single currency.

The voting pattern in the French referendum eerily foreshadowed recent political protests. Those who voted against the single currency tended to have low incomes and limited education, they lived in areas that were turning into industrial wastelands, they worked in insecure jobs, and, for all these reasons, they were deeply worried about the future (Mody 2018: 101–103). By voting against the Maastricht Treaty, they were not necessarily expressing an anti-European sentiment; rather, they were demanding that French policymakers pay more attention to domestic problems, which European institutions and policies could not solve.

He also has a new book, Eurotragedy – A Drama In Nine Acts, soon.

In his article, Mody also refers to Kaldor’s prescience from his article The Dynamic Effects Of The Common Market first published in the New Statesman, 12 March 1971 and also reprinted (as Chapter 12, pp 187-220) in Further Essays On Applied Economics – volume 6 of the Collected Economic Essays series of Nicholas Kaldor.

Basil Moore, R.I.P.

Basil Moore passed away yesterday. 💐

Post-Keynesian economics greatly influenced Post-Keynesian monetary theory. Although his work was present in Cambridge Keynesians work, such as Joan Robinson, Nicholas Kaldor, Wynne Godley and Francis Cripps, they didn’t influence the thinking on monetary matters as much as Moore did with his great book Horizontalists And Verticalists — The Macroeconomics Of Credit Money.

He does recognise Kaldor’s work in that book:

The obvious lesson to be learned from the experience with the General Theory in the past fifty years is that .. revolutionizing the way the world thinks about economic problems” is an enormously difficult task. In spite of the mountains of Keynesian exegesis that has been produced, Nicholas Kaldor was the sole English-speaking economist of the first rank to have endorsed what is here termed the Horizontalist position (1970, 1981, 1982, 1983, 1985a, b). This book represents my attempt to enlist the support of other scholars in what has at times seemed a quixotic crusade by a member of the lunatic fringe against the prevailing orthodoxy.

I regret not having met him. My only interaction was to ask him via email, where I can buy his book Horizontalists And Verticalists because it cost $450 on Amazon at the time! He didn’t know but replied recommending his book Shaking the Invisible Hand: Complexity, Endogenous Money and Exogenous Interest Rates. But later I managed to get the book. He also said that

It was my attempt to introduce endogenous money into the Macro literature, but no one has heard of it since the mainstream never reviewed it. (They gave H&V to Phil Kagan, a leading Monetarist, who didn’t much like it, but at least it was reviewed.

Noechartalists will be surprised to know that Moore also endorsed Chartalism in his 1988 book:

[page 8] Soft or fiat money refers to unbacked paper or token coins. It maintains its value because it is legally tenderable (by fiat) in settlement of debts and taxes.

…

[page 18] Currency (fiat money) is the physical embodiment of the n,onetary unit of account (numeraire) defined by the sovereign government. It is a sure and perfectly liquid store of value in units of account. It is legal tender for the payment of taxes and for the discharge of private debt obligations enforceable in courts of law. In consequence it is generally accepted as a means of payment.

…

[page 294] Money of any kind allows the breaking of the barter quid pro quo that is imposed by lack of trust and for which money is not a substitute. Even though intrinsically worthless, money is acceptable to me provided that it is also acceptable to you and to everyone else. Trust in money now comes from government guarantee of its acceptability as legal tender. “Today all civilized money is beyond the possibility of dispute, chartalist” (JMK, 5, p. 4).

…

[page 372] Fiat money represents a bridge between the world of commodity money and credit money. In its liquidity characteristics it is virtually identical to commodity money, except that it is chartalist.

There were many places I disagreed with Moore. I don’t think he was a fan of the use of expansionary fiscal policy. I don’t know why he claimed that the Keynesian multiplier doesn’t exist. But as Geoff Harcourt says in the foreword to the book Complexity, Endogenous Money and Macroeconomic Theory — Essays in Honour Of Basil J. Moore:

But, important as these contributions have been, Basil has influenced many other topics, sometimes by his innovative thinking, sometimes by being the irritant that has led other oysters to create pearls of their own. Especially is this true of his highly individual approach to the true meaning of the Keynes–Kahn–Meade multiplier concept and also to the validity of Keynes’s concept of effective demand as presented in The General Theory. Basil has made us think anew about our understanding of the natures of saving and investment, their relationship to each other, to the concept of an under-employment rest state, and also of the relationship of the macroeconomic income and expenditure accounts, balance sheets and funds statements to the behavioral relationships originally developed by Keynes and his followers. To sometimes disagree with Basil’s arguments is not at all to detract from the great stimulus he has provided for fundamental rethinks of basic, central, core concepts and relationships.

Post-Keynesian Economics has lost a giant. R.I.P., Basil Moore.

New Book: Advances In Endogenous Money Analysis

There’s a nice new book titled, Advances In Endogenous Money Analysis, edited by Louis-Philippe Rochon and Sergio Rossi.

There’s a great chapter on Nicholas Kaldor’s views on money over the years by John E. King and another by Marc Lavoie titled, Assessing Some Structuralist Claims Through A Coherent
Stock–Flow Framework. John E. King also discusses the importance of fiscal policy in Kaldor’s work:

Kaldor continued to insist on the importance of fiscal policy. The first point in his ‘constructive programme of recovery’ from the world stagflationary crisis of the early 1980s was international agreement on ‘coordinated fiscal action including a set of consistent balance of payments targets and “full employment” budgets’ (Kaldor, 1996, pp. 86, 87). Existing budget deficits, he maintained, were

largely the consequence of the low level of activity. On a ‘full employment’ basis they would show a highly restrictive picture – they would show surpluses and not deficits. Contrary to appearances, the requirement of stability is for expansionary budgets – with lower taxes and higher expenditure, and not further fiscal restriction (as is advocated, for example, by M. de Larosiere of the International Monetary Fund). (Ibid., p. 87)

International coordination was critical to the success of this strategy. Trade liberalization was not consistent with full employment: ‘under conditions of unrestricted free trade the actual volume of production and trade may in fact be considerably less than under some system of regulated trade’ (ibid., italics in the original).

There was a conference last year in honour of Nicholas Kaldor organized by Corvinus University of Budapest.

The papers by the speakers has now been published by Acta Oeconomica in their 2017 s1 issue.

Anthony Thirlwall’s paper Nicholas Kaldor’s Life And Insights Into The Applied Economics Of Growth (Or Why I Became A Kaldorian) is notable. You can access it here if you can’t access the journal.

Excerpt:

The second paper which struck an intellectual chord was Kaldor’s address to the Scottish Economic Society in 1970 entitled ‘The Case for Regional Policies’ (Kaldor, 1970). Here, at the regional level, he switches focus from the structure of production in a closed economy to the role of exports in an open regional context in which the growth of exports is considered the major component of autonomous demand (to which other components of demand adapt) which sets up a virtuous circle of growth working through the Verdoorn effect – similar in character to Gunnar Myrdal’s theory of circular and cumulative causation in which success breeds success and failure breeds failure (Myrdal, 1957). This is one of his challenges to equilibrium theory that free trade and the free mobility of factors of production will necessarily equalise economic performance across regions or countries.

A New Way To Learn Economics?

John Cassidy has a nice article titled A New Way To Learn Economics for The New Yorker on a new online introductory economics curriculum. produced by a lot of collaborators.

I went to the website which has the full book. Although there seems to be some progress, I have a strong reservation against it.

The chapter titled “Banks, money and the credit market” has a much better description on it than textbooks widely used, such as the ones by Paul Samuelson, Gregory Mankiw or Paul Krugman. On a cursory look, I didn’t find anything about the “money multiplier” model. Instead, the book says that central banks set short term interest rates and this has an effect on aggregate demand. If I missed something and if you find something orthodox, please let me know.

The chapter on fiscal policy looks like being written by fiscal hawks. There is a description of the government expenditure multiplier, which is not much different from other textbooks. There’s no mention of the more complicated nature of this process because of interactions between stocks and flows. For example, in stock-flow coherent (SFC) models, this one-step multiplier has a limited role.

Now, fiscal policy has strong effects and the book hardly does justice to any of this. It reads more like a defense of the establishment wisdom.

But it is in the area of international trade and globalization under the current rules of the game that the book is the most disappointing. The authors do tell students that it can produce “losers” but the problem of such an approach is that it doesn’t appreciate the fact that it leads to polarisation and divergences in fortunes of nations, instead of individuals. The assumption and conclusion (the same thing in most of economics!) is that if losers are compensated, fortunes of nations can converge.

This by Nicholas Kaldor, written in 1980, is change.

Not the new book, The Economy. 

As Morris Copeland emphasised, the root problem of economics is the total confusion of anyone and everyone on what money is. And his approach shows us that it’s not complicated. One just needs to study flow-of-funds or social accounting. There is hardly any emphasis of this in the book. Till then, students will remain confused and ignorant about the way the world works.

The Upshot NYT On The Kaldor-Verdoorn Law

Neil Irwin writing for The Upshot seems open to the idea that aggregate demand affects aggregate supply, quoting the work of J.W. Mason:

… But what if this is the wrong way of thinking about it? What if productivity growth is not so much an external force that proceeds in random fits and starts, but is rather deeply intertwined with the overall state of the economy and labor market?

It’s a chicken or egg problem: Does low productivity cause slow growth, or does slow growth cause low productivity?

Discussion of such matters was also welcomed by Narayana Kocherlakota on Twitter.

Recently, Simon Wren-Lewis also wrote recently in a post on his blog, Mainly Macro, titled, Why Recessions Followed By Austerity Can Have A Persistent Impact.

In standard economic theory, productivity rises explains the rise and fall of nations, although this shouldn’t really be happening because of the convergence promised by advocates of free trade!

In Kaldorian models, aka the principle of circular and cumulative causation, nations with higher competitiveness will see a large rise in production at the expense of other nations. Higher production leads to higher productivity, so the observed relation between success and productivity has a different story! Also, competitiveness has two aspects: price and non-price. Higher productivity does improve price-competitiveness. Further, I believe, competitiveness itself isn’t something fixed. Initial success feeds into higher competitiveness and the reverse for failure. So there’s a complicated story of causality.

John Maynard Keynes On Surplus Nations’ Obligations

Recently, The Economist‘s cover story declared that the government of Germany ought to expand domestic demand and its refusal to do so is a threat to the world economy. It also said, “Germany’s surpluses are themselves a threat to free trade’s legitimacy.”

Post-Keynesians have long recognized this problem with the world economy. Keynes himself said in 1941:

It is characteristic of a freely convertible international standard that it throws the main burden of adjustment on the country which is in the debtor position on the international balance of payments. … The contribution in terms of the resulting social strains which the debtor country has to make to the restoration of equilibrium by changing its prices and wages is altogether out of proportion to the contribution asked of its creditors. Nor is this all. … The social strain of an adjustment downwards is much greater than that of an adjustment upwards. … The process of adjustment is compulsory for the debtor and voluntary for the creditor. If the creditor does not choose to make, or allow, his share of the adjustment, he suffers no inconvenience. For whilst a country’s reserve cannotfall below zero, there is no ceiling which sets an upper limit. The same is true if international loans are to be the means of adjustment. The debtor must borrow; the creditor is under no such compulsion

– in Collected Works, Vol. XXV, pages 27-28.

Few things:

Keynes is building a narrative to argue that creditor nations have responsibilities, although at that time (and also at present), they have no obligation. This was the motivation for his plan for Bretton-Woods, where he proposed to impose fines on creditor/surplus nations and set out some responsibilities for them.

Also, although the above was written keeping in mind a new world order (at 1941), it’s still valid for the post-Bretton-Woods era. This is because, although floating exchange rates help making adjustments, their power is completely exaggerated.

It’s also important to keep in mind, that the world is more complicated now. Creditor/suprlus nations have achieved their status by making adjustments, i.e., by keeping wages and domestic demand low. So it’s not exactly or literally like what Keynes presented. It’s not the best of worlds in Germany or China.

Still, what Keynes said was highly insightful.

It’s also interesting that for The Economist, Germany’s behaviour is a “threat to free trade’s legitimacy.” Nicholas Kaldor also said the same in 1980:

In the absence of … measures all countries may suffer a slower rate of growth and a lower level of output and employment, and not only the group of countries whose economic activity is ‘balance-of-payments constrained’. This is because the ‘surplus’ countries’ own exports will be lower with the shrinkage of world trade, and they may not offset this (or not adequately) by domestic reflationary measures so that their imports will also be lower.

– in Foundations And Implications Of Free Trade Theory

For The Economist, Germany’s behaviour is a threat to free trade. For Post-Keynesians, Germany’s behaviour is expected (and ought to be different) and is a good reason to reject free trade.

But it’s not a bad thing that The Economist recognizes Keynes’ insights.

Nicholas Kaldor On Say’s Law And The Principle Of Effective Demand

Posted on by

Recently, a U.S. politician Rick Perry cited Say’s Law:

Here’s a little economics lesson: supply and demand. You put the supply out there and the demand will follow.

Just saying that implicitly rejects the Keynesian principle of effective demand.

But it’s interesting to see that according to Nicholas Kaldor, the principle of effective demand is not a rejection of Say’s Law.

What is Say’s Law. Usually this paragraph—from Jean Baptiste Say’s book, A Treatise On Political Economy; Or The Production, Distribution, And Consumption Of Wealth, published in 1821, page 38—is referred:

It is worth while to remark, that a product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value. When the producer has put the finishing hand to his product, he is most anxious to sell it immediately, lest its value should diminish in his hands. Nor is he less anxious to dispose of the money he may get for it; for the value of money is also perishable. But the only way of getting rid of money is in the purchase of some product or other. Thus, the mere circumstance of the creation of one product immediately opens a vent foi
other products.

In Keynesian Economics After Fifty Years, in the book, Keynes And The Modern World, ed. George David Norman Worswick and James Anthony Trevithick, Cambridge University Press, 1983, page 5, Kaldor says:

The Principle Of Effective Demand

The core of Keynes’s theory is the principle of effective demand which is best analysed as a development or refinement of Say’s law, rather than a complete rejection of the ideas behind that law.

Further, on page 6:

The originality in Keynes’s conception of effective demand lies in the division of demand into two components, an endogenous component and an exogenous component. It is the endogenous component which reflects (i.e., is automatically generated by) production, for much the same reasons as those given by Ricardo, Mill or Say — the difference is only that in a money economy (i.e. in an economy where things are not directly exchanged, but only through the intermediation of money) aggregate demand can be a function of aggregate supply (both measured in money terms) without being equal to it — the one can be some fraction of the other. To make the two equal requires the addition of the exogenous component (which could be one of a number of things, of which capital expenditure – ‘investment’ – is only one) the value of which is extraneously determined. Given the relationship between aggregate output and the endogenous demand generated by it (where the latter can be assumed to be a monotonic function of the former), there is only one level of output at which output (or employment) is in ‘equilibrium’ – that particular level at which the amount of exogenous demand is just equal to the difference between the value of output and the value of the endogenous demand generated by it. If the relationship between output and endogenous demand (which Keynes called ‘the propensity to consume’) is taken as given, it is the value of exogenous demand which determines what total production and employment will be. A rise in exogenous demand, for whatever reasons, will cause an increase in production which will be some multiple of the former, since the increase in production thus caused will cause a consequential increase in endogenous demand, by a ‘multiplier’ process.

Nicholas Kaldor, 1957. Photo via: NPR

and further on page 9:

A capitalist economy (for reasons explained below) is not ‘self-adjusting’ in the sense that an increase in potential output will automatically induce a correspond¬ing growth of actual output. This will only be the case if exogenous demand expands at the same time to the required degree: and as this cannot be taken for granted, the maintenance of full employment in a growing economy requires a deliberate policy of demand management … the mere existence of competition between sellers (‘firms’) will not in itself ensure the full utilization of resources unless all firms expand in concert. Any one firm, acting in isolation, may find that the market for its own products is limited, and will therefore refrain from expanding its production even when its marginal costs are well below the ruling price. Under these conditions involuntary unemployment could only be avoided if something – the growth of some extraneous component of demand – drives the economy forward.

So Say’s law is not wrong, it’s incomplete. Nonetheless, it’s not surprising that politicians like Rick Perry are going to use it, mislead and reject the Keynesian principle of effective demand.

tl;dr

Say’s law: supply creates demand.

Principle of effective demand: demand also creates its own supply. supply creating demand doesn’t mean the economy is running at full capacity.

What Is Equilibrium?

Posted on by

The new paper by Gennaro Zezza and Michalis Nikiforos for the Levy Institute, surveying the literature on stock-flow consistent models has a discussion on the concept of equilibrium:

In the short run, “equilibrium” is reached through price adjustments in financial markets, while output adjustments guarantee that overall saving is equal to investment. However, such “equilibrium” is not a state of rest, since the expectations that drive expenditure and portfolio decisions may not be fulfilled, and/or the end-of-period level for at least one stock in the economy is not at its target level, so that such discrepancies influence decisions in the next period.

In theoretical SFC models, the long-run equilibrium is defined as the state where the stock-flow ratios are stable. In other words, the stocks and the flows grow at the same rate. The system converges towards that equilibrium with a sequence of short-run equilibria, and thus follows the Kaleckian dictum that “the long-run trend is but a slowly changing component of a chain of short-run situations; it has no independent entity” (Kalecki 1971: 165). The adjustment takes place because stocks and stock-flow ratios are relevant for the decisions of the agents of the economy. If stocks did not feed back into flows, the model may generate ever-increasing (or decreasing) stock-flow ratios: a result that might be stock-flow consistent, but at the same time unendurable. The convergence towards the long-run equilibrium also depends on more conventional hypotheses regarding the parameters of the model.

So equilibrium is a state where stock-flow ratios are stable.

Of course equilibrium just means that and doesn’t automatically translate to full employment, for example. One can imagine stock-flow ratios such as public debt/gdp, private debt/gdp may converge to some level such as 80%, 50% respectively but with unemployment at, say, 5%.

Also, it’s worth mentioning—especially in open economies—there is in general no automatic/market mechanism which guarantees that stock-flow norms are converging to some stable ratios.

Let me offer an alternative viewpoint for the short run.

In the short run, there’s really no concept of equilibrium because there is no heavenly Walrasian auctioneer in most markets. As pointed out by Nicholas Kaldor, there are dealers who are both buyers and sellers simultaneously. Dealers quote bid/ask prices and the quantities they are willing to buy or sell. Since there is a mismatch in demand and supply of “outside buyers” and “outside sellers”, dealers accumulate inventories or stocks. Dealers make a business out of the bid-ask spread. In non-financial markets, the terminology is slightly different. You won’t find a board with bid/ask prices at a car dealer, but the concept is similar. Here even the producer has inventories in the goods market. In the services market, whatever is demanded is supplied (or put in queue or refused if capacity is reached).

So there’s no equilibrium to be reached in the short-run. It’s always in disequilibrium. Sometimes neoclassical authors make it look like accounting identities are violated in disequilibrium and satisfied in equilibrium arranged by the Walrasian auctioneer. But in SFC models, it’s illogical to have such a thing. Accounting identities must always be respected. At all times, between all time periods, even infinitesimally small.

In real life, especially because of complications of the open economy, there is no such thing as an equilibrium or a tendency to move toward any equilibrium via market forces.

Still, the concept of equilibrium is useful even in SFC models. One can start with a state with a stable stock-flow ratios and then study what happens if some parameter or some exogenous variable is changed or a set of them are changed simultaneously. The dynamics may or may not reach equilibrium in the long run but we can study what happens in the traverse.
