A couple of years ago Michel De Vroey felt the urge to write a defense of Robert Lucas’ denial of involuntary unemployment: What explains the difficulty of constructing a theory of involuntary unemployment? Is it, as argued by Lucas, that the “thing” to be explained doesn’t exist, or is it due to some deeply embedded premise of economic theory? My own view tilts towards the latter. Economic theory is concerned with fictitious parables. The premises upon which it is based have...

What is Post Keynesian Economics? John Maynard Keynes’s 1936 book The General Theory of Employment, Interest, and Money attempted to overthrow classical theory and revolutionize how economists think about the economy. Economists who build upon Keynes’s General Theory to analyze the economic problems of the twenty-first-century global economy are called Post Keynesians. Keynes’s “principle of effective demand” (1936, chap. 2) declared that the axioms...

Every dollar of increased government spending must correspond to one less dollar of private spending. Jobs created by stimulus spending are offset by jobs lost from the decline in private spending. We can build roads instead of factories, but fiscal stimulus can’t help us to build more of both. This form of “crowding out” is just accounting, and doesn’t rest on any perceptions or behavioral assumptions. John Cochrane What Cochrane is reiterating here is nothing but Say’s law,...

Economic modeling — a realist perspective To his credit Keynes was not, in contrast to Samuelson, a formalist who was committed to mathematical economics. Keynes wanted models, but for him, building them required ‘ a vigilant observation of the actual working of our system.’ Indeed, ‘to convert a model into a quantitative formula is to destroy its usefulness as an instrument of thought.’ That conclusion can be strongly endorsed! Modern economics has become...

The fundamental econometric dilemma Many thanks for sending me your article. I enjoyed it very much. I am sure these matters need discussing in that sort of way. There is one point, to which in practice I attach a great importance, you do not allude to. In many of these statistical researches, in order to get enough observations they have to be scattered over a lengthy period of time; and for a lengthy period of time it very seldom remains true that the...

Just face it — austerity policies do not work!  If failing to understand some basic Keynes­ian relations is a part of the explanation of what happened, there was also another, and more subtle, story behind the confounded economics of austerity. There was an odd confusion in policy thinking between the real need for institutional reform in Europe and the imagined need for austerity – two quite different things … An analogy can help to make the point clearer:...
