Neoliberalism, Keynesian Economics, and Responding to today's Inflation

 

Q&A Session

The lecture here. Note that it missed a few minutes at the beginning and the slides are not showing, with Professor Stiglitz at the upper right corner. It is still pretty engaging and wroth reading. There is a link to the slides that are not showing up. The actual lecture will be published in the first issue of ROKE in 2024.

 

I'll post link to the published version when it's done.

The American Political Economy Tradition

If Cohen and De Long (2016) are to be believed, there is an American Political Economy tradition, that harks back to Alexander Hamilton, that goes against the free market canon of the profession. In their view, the American Political Economy tradition consist of an interventionist approach to economic policy, that arguably should be seen as neomercantilist [1]. Classical political economy, as represented by their main figures in the United Kingdom, Adam Smith and David Ricardo, upheld the laissez-faire and free market tradition, and in this view the same would be true for the marginalist or neoclassical tradition. In that respect, some might see a continuity between both schools of thought and the American Political Economy tradition would be a somewhat heterodox tradition from its inception, at least on policy issues.

On central bank independence, and Brazilian monetary policy

The issue is back in the news. This time in Brazil (it was briefly an issue here when Trump did not reappoint Yellen, and then complained about Powell's interest rate where too high). At any rate, I always thought that there were good reasons for skepticism about central bank independence (CBI). As noted by Massimo Pivetti in this old piece on the Maastricht Accord and the, at that time, plan for the euro, the main reason to be doubtful is related to the interaction of monetary policy and fiscal policy. And as Quantitative Easing in the post-Global Financial Crisis has shown, central banks have become again fiscal agents of the state (never stopped being that, in all fairness).

The other important reason alluded by Pivetti for doubting CBI is the effects of the interest rate on the exchange rate and balance of payments. This is a quote from Pivetti:

And one could add, through the exchange rate, the effects on inflation also matter. This can be illustrated by the discussion of the Brazilian case. Lula has been very critical of the policies of the Brazilian Central Bank (BCB), and of the higher interest rates, since the campaign last year, and some sort of a truce has been in the works, with him being less direct (or at least that has been reported).

At any rate, the notion is that the higher interest rate is inimical to growth, even though Brazil did grow with relatively high interest rates in his first two mandates. The important thing to note is that Brazil had back then a relatively high and positive interest rate differential, that is a domestic nominal interest rates higher than the sum of external interest rate (the US rate) plus the risk premium (e.g. J.P. Morgan's Emerging Market Bond Index, EMBI), plus the expected nominal devaluation. In fact, as the interest rate differential (here just the difference of the BCB's Selic rate, the Fed Funds plus the EMBI) was coming down, the exchange rate depreciated.

Note that inflation accelerated and has been above the BCB's target only in more recent times, and the exchange rate is only one component of that. The higher prices of energy commodities, and the snags on the supply chain matter in the Brazilian case too. But the higher interest rate, and the higher and positive differential, did allow eventually for the stabilization of the exchange rate.

There is ample space to discuss how high the rate should be, but I'm doubtful that it can be close to zero or very low as suggested recently by André Lara Resende (that since my last post on his views, see here, has move away from Cochrane's fiscal theory of the price level, and closer to MMT; I just read his new book and that seems to be the case; on Cochrane's views on inflation see this video, also with John Taylor and Kevin Warsh).

Below the BCB's Selic rate and the Fed Funds for a longer period, starting after the stabilization of the Real Plan in the 1990s.

 
As one can see (Selic on the left, and Fed Funds on the right), the hike in the Brazilian rate has accompanied the hikes in the US, which are totally unnecessary, in my view, since inflation is cost push and not demand pull, but that's another story. But the fact remains that the ability of central banks in the periphery to conduct monetary policy independently from what happens in the center is still curtailed. Note that the reduction of Brazilian rates, from higher levels (since a positive differential must be maintained to avoid capital flight and depreciation), was possible because the Fed Funds for the most part has been very low.
 
That's probably the more important discussion about the CBI. Not just independence from financial interests, as John Kenneth Galbraith used to suggest, but also the degree of independence in a world with a hegemonic currency.

PS: In the Brazilian case, the really important question for the Lula government will be his ability to increase spending beyond the fiscal ceiling. That, and the ability to eliminate hunger, and reduce poverty rates, would determine the political success of his administration.

Price and Prejudice

Working paper on the Post Keynesian Economics Society website. From the abstract:

The current debate on the causes of inflation is dominated by a particular view of what caused the inflationary acceleration in the 1970s, the so-called Great Inflation. In this view inflation is always and everywhere a demand phenomenon and requires contractionary monetary policy to be kept under control. The alternative view put forward by many heterodox authors emphasize what might be termed the oligopolistic view of inflation. In this paper we trace the limitations of both views for the center and the periphery.

Barkley-Rosser Jr. (1948-2023)

At the ASSA in San Diego, before the pandemic

It is hard to believe that Barkley has passed away. I met Barkley long ago, when I was still a PhD student in the 1990s, at the Eastern Economic Association Meeting, which still is one of the organizations that congregates both mainstream and heterodox economists with some degree of interaction. Perhaps the only such conference that still exists in the US. Barkley moved in between the mainstream and the heterodoxy. He should be seen, to a great extent, in the way he described the heterodoxy, as trying to break away from orthodox thinking. Although I disagreed about that definition as a description of heterodox economics, I think his definition reflected very well what he was trying to do.

His view of heterodoxy was based on the idea that the mainstream was ossified and didn't capture the complexity of actual economies. In part, he dealt with that by assuming non-linearities, and discontinuities and noting the unrealistic character of rational maximizing assumptions in a complex world. However, I think some of his most interesting work had an institutional character and was based on his joint work with his wife Marina on comparative economic development, in its third edition now.

He was the founding editor of the Review of Behavioral Economics, having been before the editor of Journal of Economic Behavior & Organization, he was interested in Econophysics (he wrote the entry for the New Palgrave). He was also a blogger for one of the oldest and best established econ blogs, EconoSpeak (a short entry after his death). He was, of course, the co-editor of the New Palgrave. A great loss for the profession and all that knew him.

New book: Varieties of Capitalist Experience

Over the past twenty years there has emerged a compelling new discourse on varieties of capitalism. That discourse has an appealing common sense which challenges the view there is no alternative to free market capitalism. The initial view had a microeconomic focus that made firms the fulcrum of analysis. It distinguished between liberal market and coordinated market economies. Subsequently, there has emerged a second-generation literature which adopts a macroeconomic perspective that emphasizes differences in drivers of growth. This book provides a collection of essays that engage those second-generation concerns and questions.

Luigi Pasinetti (1930-2023)

Pasinetti, Garegnani and the president of Italy in 2010

Last week, in my senior seminar on the history of economic thought, I made the kids read a paper by Pasinetti on "Progress in Economic Science", which was published in a book edited by Boehm, Gehrke, Kurz and Sturn. It's a short defense of pluralism in economics on the basis of the co-existence of Kuhnian paradigms, with a relatively optimistic view of the possibility of progress, in a discipline in which, as he noted, the object of analysis is changing continually, the ideas of the researchers might affect the functioning of the object of study, and value judgments cannot be avoided, in part because they affect everyday material conditions. As he said: "It is enough to think of the devaluation of a currency, or of the movements of wages and salaries, to realize how deeply these phenomena affect everybody’s pocket."

Sadly Pasinetti has died yesterday. He was perhaps the last great name of the Anglo-Italian Cambridge School, that tried to put the works of the classical authors and Marx and the Keynesian Revolution together, and intimately associated with the work of Piero Sraffa. I remember reading a paper on how the school could be divided in a more Marxian strand (with Pierangelo Garegnani as the main author) and a Ricardian one, around Pasinetti. This also had political implications with Pasinetti representing the center right Christian Democrats, and Garegnani on the left, linked to the Communist Party. I once told that to Garegnani, who dismissed the idea of Sraffian schools.*

Pasinetti will be remembered for his work on the Cambridge distribution models, the famous Kaldor-Pasinetti model, the participation in the capital debates, and his work on a classical model of structural growth. Personally, his book on the theory of production (Lectures on the Theory of Production) and his discussion and critique of the Maastricht fiscal limits remain the two of his contributions that influenced me the most.

I should note that this comes after a series of deaths in the profession that have significantly affected the heterodox community, and me personally. Vicky Chick, with whom I was supposed to work for my PhD, and Jim Crotty, two of the more creative thinkers within Post Keynesian economics have passed. Also, on a personal note, Nilüfer Çagatay, my colleague in Utah, and Barkley Rosser, the co-editor of the New Palgrave passed away this month. The heterodox community is in mourning.

* The other would be the Smithian one, with Sylos-Labini as the main leader, and a Socialist bent in politics.
