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).

Marc Lavoie On New Behavioural Economics

So,

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2017 was awarded to Richard H. Thaler “for his contributions to behavioural economics”.

as per the Nobel Prize’s website.

In his book, Post-Keynesian Economics: New Foundations, (2014), Marc Lavoie has a nice discussion/critique on what’s called “New Behavioural Economics”:

Stock-Flow Consistent Agent-Based Models

I wasn’t too excited about “agent-based models” before this, but I saw this paper What Drives Markups? Evolutionary Pricing In An Agent-Based Stock-Flow Consistent Macroeconomic Model by Marc Lavoie (co-authored with Pascal Seppecher and Isabelle Salle) and it got me a bit interested.

From the paper:

ABMs are conceived to analyze out-of-equilibrium dynamics and adaptation processes
from heterogeneous and interacting entities … On a more specific note, we use a stock-flow consistent (hereafter, SFC) framework … there has been a multiplicity of macroeconomic models that combine two important features: the principle of decentralization/disaggregation which is found in ABM and the principle of stock-flow consistency … In an ABM, macroeconomic variables are the result of a simple process of aggregation of individual data, as in the real word [sic] …, so that the accounting accuracy provided by the SFC ensures the relevance of the aggregation process …, as well as the interconnected nature of the balance sheets of all agents. Symmetrically, AB principles could provide micro-foundations to SFC macroeconomics, that is, a way to logically articulate and rigorously organize the interactions between the micro and the macro levels.

The Paradox Of Costs And Other Macro Paradoxes

In the last postEffective Demand And The Labour Market, I argued how the effect of raising minimum wages on employment is straightforward—it’s beneficial. This seems contradictory to the “intuition”—which it is not really, it’s learning to think like an economist—which suggests that raising wages will lead to unemployment.

Economists have been struggling to find answers to analysis which do not find empirical support. But they needn’t, as explanations are already available. You just need to take the Keynesian principle of effective demand more seriously.

Keynes highlighted the paradox of thrift — reduction in the propensity to consume (or rise in the propensity to save) leads to a fall in output. This goes against intuition, which considers saving as only positive. Of course the solution is to not promote a policy in which consumers spend like crazy. So fiscal policy has to be relaxed if consumers want to save a lot.

And there are other paradoxes such as the paradox of costs, which is related to the discussion on wages, profits, output and employment in the previous post. Here’s a table from Marc Lavoie’s fantastic book, Post-Keynesian Economics: New Foundations.

Marc Lavoie’s list of macro paradoxes

Intuition derived out of learning New Consensus Economics will lead one to believe that raising real wages will lead to a fall in profit rates. Michal Kalecki highlighted that this isn’t the case. As Marc Lavoie says, “what seems reasonable for a single individual or nation leads to unintended consequences or even to irrational collective behaviour when all individuals act in a similar way.”

Further, Marc Lavoie says:

The paradox of costs, in its static version, says that a decrease in real wages will not raise the profits of firms and will instead lead to a fall in the rate of employment. This was explained by Kalecki in a Polish paper first written in 1939, where he concluded that ‘one of the main features of the capitalist system is the fact that what is to the advantage of a single entrepreneur does not necessarily benefit all entrepreneurs as a class’. Its dynamic version has been proposed by Robert Rowthorn. It says that rising real wages (relative to productivity) can generate higher profit rates. This flies in the face of a microeconomic analysis that would demonstrate that lower profit margins generate lower profit rates. But if higher real wages generate higher aggregate consumption, higher sales, higher rates of capacity utilization and hence higher investment expenditures, profit rates will be driven up.

So while it may be beneficial to an individual firm to reduce wages and get a higher profit rate, it will be the reverse if everyone tries to do it.

For a fantastic discussion of these paradoxes, refer to the book Post-Keynesian Economics: New Foundations. Chapter 1 can be accessed for free at the publisher’s website.

Kalecki. Geniusz Zapomniany

h/t Matias Vernengo, I came across this nice short documentary Kalecki. Geniusz Zapomniany (Kalecki: Forgotten Genius) on the life of the Polish 🇵🇱 economist Michal Kalecki.

I also came across this nice article by Marc Lavoie, Kalecki And Post-Keynesian Economics, in the book, Michał Kalecki In the 21st Century, edited by Jan Toporowski and Łukasz Mamica and published in 2015. Toporowski also appears in the documentary above.

In that article Marc Lavoie says that although the work of Kalecki is “extensive and paramount”, some Post-Keynesian authors have been reluctant to accept it. Marc Lavoie argues that it ought to not be that way and that “some post-Keynesians believe that Kalecki, rather than Keynes, provides the best foundations for post-Keynesian theory”.

The importance of national accounts and flow of funds is underemphasized by economists. It’s as crucial as calculus and real analysis is to physics. Economists confound income flows with financial flows, but matters of national accounts were kindergarten stuff for Kalecki. With such advantage, Kalecki made a huge amount of progress in his work on economic dynamics.

Francis Cripps And Marc Lavoie’s Short Biography Of Wynne Godley

There’s a new bookThe Palgrave Companion To Cambridge Economics which features among other things biographies of Wynne Godley, Joan Robinson and Nicholas Kaldor and other notable Cambridge economists. Wynne Godley’s biography—Wynne Godley (1926-2010)—is by his closest collaborators – Francis Cripps and Marc Lavoie (pp. 929-953)

You can access the book on Springer, if you have subscription or preview it on Google Books.

Excerpt:

One interpretation of Godley’s theoretical work is that it is a quest for the Holy Grail of Keynesianism. Keynesians of all stripes had for a long time mentioned the need to integrate the real and the monetary sides of economics. Integration was all the talk, but for a long time, little seemed to be achieved … The main purpose of the Godley and Cripps’s 1983 book is to amalgamate the real and the financial sides, providing a theory of real output in a monetary economy …

Godley believed that Keynesian orthodoxy ‘did not properly incorporate money and other financial variables’ (ibid.: 15). Godley and Cripps and their colleagues ‘found quite early on that there was indeed something deficient in most macroeconomic models of the time’, including their own, ‘in that they tended to ignore constraints which adjustments of money and other financial assets impose on the economic system as a whole’ (ibid.: 16). Interestingly, Godley was aware of the work being carried out at about the same time by Tobin and his Yale colleagues, as well as by others such as Buiter, Christ, Ott and Ott, Turnovsky, and Blinder and Solow, who emphasized, as Godley and Cripps (ibid.: 18) did, that ‘money stocks and flows must satisfy accounting identities in individual budgets and in an economy as a whole’. Still, Godley thought that the analysis of the authors in this tradition was overly complicated, in particular because they assumed some given stock or growth rate of money, ‘leaving an endogenous rate of interest to reconcile’ this stock of money with the fiscal stance (Godley 1983: 137). Godley and Cripps (ibid.: 15) were also annoyed by several of the behavioural hypotheses found in the work of these more orthodox Keynesians, as they ‘could only give vague and complicated answers to simple questions like how money is created and what functions it fulfils’. The Cambridge authors thus wanted to start from scratch, with their own way of integrating the real and the financial sides, thus avoiding these ‘tormented replies’ (ibid.) …

Ultimately, Godley’s desire to present a definitive treatise based on consistent macroeconomic accounting gave rise, nearly 25 years later, to the Monetary Economics book (Godley and Lavoie 2007a) …

“In The Long Run”

But this long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task, if in tempestuous seasons they can only tell us, that when the storm is long past, the ocean is flat again.

–  John Maynard Keynes, A Tract on Monetary Reform (1923), Ch. 3, p. 80.

As you might know, the Indian government cancelled the legal tender nature of majority of bank notes in circulation, earlier this month and asked Indians to deposit them at banks or exchange them for new. The aim according to the government was to curb counterfeiting and what’s called black money here. This is damaging as a large amount of transaction is in bank notes and the implementation has been a failure. People have been standing in queues for the whole day and some even reach banks at 2 am to get a good position in the queue. For many, standing in queues means that the day’s labour is lost. For others, there are delays in wage payments since their employers have problems getting hold of new bank notes. More than 50 people have died. Even 11 bank managers have died due to stress and work overload.

Despite this we keep hearing from the government and the ruling political party’s defenders that the benefits will be long term.

The previous Indian Prime Minister (who was the nation’s leader during mid 2004-mid 2014), Manmohan Singh gave a scathing speech in the Indian Parliament yesterday in which he quotes Keynes on the long run. Manmohan Singh was a student at Cambridge and his heroes are Nicholas Kaldor and Joan Robinson and presumably John Maynard Keynes as well. In this era where politicians are promoting neoliberal ideas, it’s good to see the master being quoted in a Parliament.

This question about the long-term reminds me of super-hysteresis which was referred by Marc Lavoie recently in an article for INET. It’s closely related to the Kaldor-Verdoorn law in which demand affects supply.  The damage done to the demand side because of slowdown in production caused by the Indian government’s poor implementation of its decision to replace majority of bank notes by value affects the supply side as well. Almost nobody who talks about the long-term benefits talks about this issue.

Remarkable Admission On Fiscal Policy

There’s a paper by Jason Furman who is the Chairman of the Council of Economic Advisers which concedes how wrong economists were on fiscal policy. The link is a file hosted at the White House’s website! The paper starts off with a remarkable admission on fiscal policy (h/t and words borrowed from Jo Michell)

A decade ago, the prevalent view about fiscal policy among academic economists could be summarized in four admittedly stylized principles:

  1. Discretionary fiscal policy is dominated by monetary policy as a stabilization tool because of lags in the application, impact, and removal of discretionary fiscal stimulus.
  2. Even if policymakers get the timing right, discretionary fiscal stimulus would be somewhere between completely ineffective (the Ricardian view) or somewhat ineffective with bad side effects (higher interest rates and crowding-out of private investment).
  3. Moreover, fiscal stabilization needs to be undertaken with trepidation, if at all, because the biggest fiscal policy priority should be the long-run fiscal balance.
  4. Policymakers foolish enough to ignore (1) through (3) should at least make sure that any fiscal stimulus is very short-run, including pulling demand forward, to support the economy before monetary policy stimulus fully kicks in while minimizing harmful side effects and long-run fiscal harm.

Today, the tide of expert opinion is shifting the other way from this “Old View,” to almost the opposite view on all four points. This shift is partly the result of the prolonged aftermath of the global financial crisis and the increased realization that equilibrium interest rates have been declining for decades. It is also partly due to a better understanding of economic policy from the experience of the last eight years, including new empirical research on the impact of fiscal policy as well as observations of the reaction of sovereign debt markets to the large increases in debt as a share of GDP in the wake of the global financial crisis. In the first part of my remarks, I will discuss the theory and evidence underlying this “New View” of fiscal policy (with, admittedly, the core of this theory being an “Old Old View” that dates back to John Maynard Keynes and the liquidity trap).

Compare that to the Post-Keynesian view, which according to Wynne Godley and Marc Lavoie in their book Monetary Economics written before the crisis (from chapter 1, Introduction):

The alternative paradigm, which has come to be called ‘post-Keynesian’ or ‘structuralist’, derives originally from those economists who were more or less closely associated personally with Keynes such as Joan Robinson, Richard Kahn, Nicholas Kaldor, and James Meade, as well as Michal Kalecki who derived most of his ideas independently.

… According to post-Keynesian ideas, there is no natural tendency for economies to generate full employment, and for this and other reasons growth and stability require the active participation of governments in the form of fiscal, monetary and incomes policy.

Marc Lavoie On The DSGE Emperor

Marc Lavoie has an excellent new article at the Institute For New Economic Thinking website titled Rethinking Macroeconomic Theory Before The Next Crisis.

Excerpt:

In this article, I have tried to stress that there is considerable dissatisfaction with the current state of mainstream macroeconomics and with the quasi-dictatorial directive that the only game to be played in town is the adoption of the DSGE model.

Some orthodox economists believe that mainstream economics holds under normal conditions (Richard Koo’s yang phase), but that it needs to be modified under zero-lower bound conditions or during balance sheet recessions (Koo’s yin phase). Macroeconomic theory needs to be revised both for the yang and the yin phases. Providing new clothes to the Naked Emperor of mainstream economics won’t do; the Emperor needs to be dethroned.
