Keynesian vicissitudes

Since the crisis that began in 2008, the economist whom Robert Skidelsky calls “the master” has made a dramatic comeback among Anglo-Saxons. Many British and American economists think we are in a Keynesian moment – a depression similar to the one in response to which Keynes wrote his General Theory in 1936. For example, in his book End This Depression Now!, published earlier this year, Paul Krugman writes that we are in “essentially the same kind of situation that John Maynard Keynes described back in the 1930s”. The fundamental problem in the world economy, Anglo-Saxon economists such as Krugman argue, is the same as at that time: a lack of aggregate demand. Measures are therefore needed to stimulate demand – in particular, expansionary fiscal or monetary policy. We are all Keynesians again.

However, at precisely the moment Anglo-Saxons rediscovered Keynes,Germans seem to have turned against him. Apparently most Germans, who now seem to have nothing but derision and contempt for Keynesian economists such as Krugman, have drawn the opposite conclusion from the crisis as Anglo-Saxons. As one senior German Christian Democrat politician put it bluntly at a talk last year when asked whether it was necessary to take measures to stimulate demand, “the old Keynesian paradigm is not valid”. Germans fear inflation much more than deflation (see for example this week’s Spiegel cover story) and  reject the idea of expansionary fiscal or monetary policy. What the economic historian Adam Tooze calls the “anti-debt” consensus in Germany is epitomised by the Schuldenbremse, or debt break, that Germany introduced in 2009 and has now exported to the rest of the eurozone. 

Nor is it just the German right that has turned against Keynes since the crisis began. In December 2008, Peer Steinbrück, then the Social Democrat finance minister (i.e. the job Lafontaine held in 1999) in Merkel’s Grand Coalition, attacked the “crass Keynesianism” of the British government under Gordon Brown. (That in turn prompted an angry response from Krugman, who called the German government “boneheaded”.) For Steinbrück the crisis was caused by “credit-financed growth”; the solution, therefore, could hardly be more credit-financed growth. Steinbrück will be the Social Democrat candidate for chancellor in next year’s election in Germany.

Perhaps part of the reason why even Germans such as Steinbrück dislike Keynes so much is that, according to him, surpluses as well as deficits are a problem. In 2012 Germany is expected to have a trade surplus of $220 billion - bigger than any country in the world, including China. To Keynesians, this is unsustainable. As George Soros has arguedno country can run a chronic trade surplus without others running deficits.” Even the Conservative British Prime Minister David Cameron has urged Germany to reduce its huge trade surplus. This is a rather odd situation: a centre-right British politician such as Cameron using a Keynesian argument that the centre-left German politician such as Steinbrück would presumably see as “crass”.
