Keynes Is Hot, Hot, HOT Right Now!

Our 2008 economic crash has only one real historical analogue - the Great Depression. Keynes was the best economist on the scene then, and he can be usefully read now:

We have learned since September that the present generation of economists has not figured out how the economy works. The vast majority of them were blindsided by the housing bubble and the ensuing banking crisis; and misjudged the gravity of the economic downturn that resulted; and were perplexed by the inability of orthodox monetary policy administered by the Federal Reserve to prevent such a steep downturn; and could not agree on what, if anything, the government should do to halt it and put the economy on the road to recovery. By now a majority of economists are in general agreement with the Obama administration's exceedingly Keynesian strategy for digging the economy out of its deep hole. Some say the government is not doing enough and is too cozy with the bankers, and others say that it is doing too much, heedless of long-term consequences. There is no professional consensus on the details of what should be done to arrest the downturn, speed recovery, and prevent (so far as possible) a recurrence. Not having believed that what has happened could happen, the profession had not thought carefully about what should be done if it did happen.

Baffled by the profession's disarray, I decided I had better read The General Theory. Having done so, I have concluded that, despite its antiquity, it is the best guide we have to the crisis. And I am not alone in this judgment. Robert Skidelsky, the author of a superb three-volume biography of Keynes, is coming out with a book titled Keynes: The Return of the Master, in which he explains how Keynes differed from his predecessors, the "classical economists," and his successors, the "new classical economists" and the "new Keynesians"--and points out that the new Keynesians jettisoned the most important parts of Keynes's theory because they do not lend themselves to the mathematization beloved of modern economists.
