Good reasons to become a Keynesian — LARS P. SYLL

Below is a revealing quote by Richard Posner from today’s post on the blog of Lars P. Syll. It sums up some of the economics mainstream’s attitudes towards Keynes’ original work, how neglected it is by those arguing against its importance, and its continuing relevance.

I first read Keynes’ General Theory when in my final year of school, before I went on to university. While finding it difficult, it was also inspiring to me and full of insight. In particular, the notion that unacceptable levels of unemployment are a periodic characteristic of capitalist economies and require government action to remedy, truly hit home. It cemented my Keynesian position for some years.

I have since rowed back from being a confident and dedicated Keynesian, although I remain influenced by leftist and other radical economists. Where appropriate, I find that the interdisciplinarity of political economy can also be helpful, not least in the study of development as a process of economic and social change.

Many of those now known as post-Keynesians, who profess to carry the true mantle of Keynes’ original thinking, also wrote on economic development. This is true in the case of key figures Michal Kalecki, Nicholas Kaldor and Joan Robinson, all of whom strongly influenced the so-called Cambridge School and its radical or heterodox offshoots.

Posner’s full quote can be found at the link below.

Until [2008], when the banking industry came crashing down and depression loomed for the first time in my lifetime, I had never thought to read The General Theory of Employment, Interest, and Money, despite my interest in economics … I had heard that it was a very difficult book and that the book had been […]

Some (political economy) thoughts on the response to Covid-19 – capitalism, socialism and the role of the state

The big state is back with a vengeance, if it ever went away. The apparent suddenness and rapid escalation of the spread of the coronavirus has called forth an almost equally rapid increase in the scope of state intervention in many nations. Countries that had spurned a move to state capitalism have suddenly found themselves having to embrace it.

Authoritarian state capitalist, though ostensibly communist, China, took a while to respond to the outbreak, but once it did, it acted forcibly and, for now at least, it seems to have stemmed the tide. But democratic Japan, South Korea and Taiwan seem also to have responded relatively effectively to the outbreak, at least compared with many other countries.

The UK government has so far pledged a massive fiscal programme of stimulus, including wage subsidies, bridging loans for firms, and at the time of writing is about to announce support for the self-employed as well. Private sector rail company franchises have been suspended in the wake of collapsing ticket sales. The health service has been promised whatever it needs financially to deal with the virus. Private firms are being asked to switch production to medical supplies as fast as possible. The post-crash decade of austerity was already somewhat at an end, but now it has been dramatically, inevitably put into reverse gear. Continue reading

Keynesian economics – back from the dead?

Here is an interesting recent lecture given by Robert Rowthorn on the “main developments in macroeconomics since the anti-Keynesian counter-revolution 40 years ago.” It can be downloaded for free. Alternatively the video of the lecture can be viewed here.

Rowthorn is Emeritus Professor of Economics at Cambridge University. Back in the 70s and 80s he was very much a Marxist, but has since moved away from that commitment and written on a wide range of topics, from Kaleckian growth and distribution theory to deindustrialisation in the advanced economies and the economics of the family.

For those who are interested in development economics, he supervised the PhD of another prominent Cambridge economist, Ha-Joon Chang, who has written a number of popular books alongside his academic work.

This is the rest of the abstract of Rowthorn’s paper:

It covers both mainstream and heterodox economics. Amongst the topics discussed are: New Keynesian economics, Modern Monetary Theory, expansionary fiscal contraction, unconventional monetary policy, the Phillips curve, hysteresis, and heterodox theories of growth and distribution. The conclusion is that Keynesian economics is alive and well, and that there has been a degree of convergence between heterodox and mainstream economics.

All of these topics are relevant to today’s economic problems, and Rowthorn argues that “many leading economists in the USA and the UK have Keynesian sympathies”.

Geoff Harcourt on Keynesian theory

In this enlightening video, Professor Geoff Harcourt, who was a distinguished pupil and colleague of Joan Robinson at Cambridge University, discusses a range of issues in Keynesian and post-Keynesian economics.

He covers the need for pluralism in economics; his definition of post-Keynesianism; the work of some of its key protagonists; uncertainty and its impact on business and the economy; the capital theory debates; and finally his vision for analysing a modern capitalist economy, and his most enduring intellectual influences.

Hyman Minsky explains his financial instability hypothesis

In this rare video, Hyman Minsky explains his financial instability hypothesis. The video dates from 1987, but Minsky was prescient in originating a theory that characterises capitalist economies with developed financial systems as inherently unstable and requiring the intervention of ‘Big Government’ (counter-cyclical fiscal policy) and a ‘Big Bank’ (the central bank acting as lender of last resort). His FIH has become much more widely known since the advent of the 2008 financial crisis.

Minsky was influenced by his teacher at Harvard, Joseph Schumpeter, as well as by John Maynard Keynes and Michal Kalecki. His work falls under the post-Keynesian tradition, emphasising the role of finance and the importance of effective demand in the economy, with the former a major cause of instability in the form of booms and busts. His thinking also incorporated ideas on institutions such as households, firms, banks, and governments, and explored how their balance sheets of assets and liabilities evolve over business cycles.

Keynes against capitalism

Crotty Keynes Against CapitalismJohn Maynard Keynes did not wish to merely save capitalism ‘from itself’ but to replace it with ‘Liberal Socialism’. That is the controversial claim made in a new book by the distinguished radical economist James Crotty, whose work ‘attempts to integrate the complementary analytical strengths of the Marxian and Keynesian traditions’.

The book, Keynes Against Capitalism, subtitled His Economic Case for Liberal Socialism, draws heavily on textual evidence found in the collected works of Keynes himself, from the 1920s through to the end of his life in 1946. This is both its strength and its weakness.

Without wishing to get into debate over semantics, one could find oneself agreeing with much of the argument ie that Keynes did in fact wish to replace capitalism with a radically different system called Liberal Socialism, but to say, in some ways, so what? The book is a fine scholarly read, but I found myself questioning whether Keynes’ (Crotty’s?) Liberal Socialism, for all its admirable socially transformative aims, would be both feasible and sustainable. Continue reading

Keynes and the conceptual cul-de-sac of General Equilibrium

Economist John Maynard Keynes

“The reasons for which Keynes’s arguments fail to translate into the orthodox paradigm are not because they are vague, confused or poorly formulated. They fail to translate, instead, because they identify and address crucial flaws in the structure and logic of the dominant paradigm. As Keynes himself put it, what he hoped to do is ‘convince [us] that Walras’ theory, and all others along those lines are little better than nonsense’. He was able to see, like Kornai, that the Walrasian ideal is ultimately ‘a special branch of mathematics’, which employs ‘logical reasoning [but] from arbitrary assumptions’, making it more an ‘intellectual experiment’ than a theory in the mould of the sciences.

The real problem which far too many economists have had with understanding Keynes’s arguments exactly as he expressed them is an intransigent desire to believe that, as once said by Debreu in an interview, ‘the superiority of the liberal economy is incontestable and can be mathematically demonstrated’. The problem with this conviction is that the economy that Debreu had in mind has little connection with reality. It is time, if we want in the future to avoid the terrible waste, not just of the past ten years, but of the many other times that liberal economies have so clearly failed to provide for full employment, that we turn our attention to understanding more accurately not the economic society in which we might wish to live but the one in which we actually live. It is in this regard that Keynes, read without the desire to adhere to the conventional wisdom of the Walrasian General Equilibrium paradigm, provides a truly valuable starting point.”
