What is it about German economics?

I recently had the privilege to speak in Berlin at the 10th anniversary celebration of the Macroeconomic Policy Institute (IMK). (The talk I gave, on the Knowledge Transmission Mechanism, is here if anyone really wants to watch it.) I had known about the IMK for some time through reading incisive posts by Andrew Watt on the Social Europe website, but more recently I had been citing important papers by other IMK economists looking at the costs of austerity. You could describe the IMK group within Germany in various ways (see below), but one would be an island of Keynesian thinking in a sea that was rather hostile to Keynesian ideas.

As my talk, and this subsequent post, focused on how Keynesian ideas are pretty mainstream elsewhere, this raises an obvious puzzle: why does macroeconomics in Germany seem to be an outlier? Given the damage done by austerity in the Eurozone, and the central role that the views of German policy makers have played in that, this is a question I have asked for many years. The textbooks used to teach macroeconomics in Germany seem to be as Keynesian as elsewhere, yet Peter Bofinger is the only Keynesian on their Council of Economic Experts, and he confirmed to me how much this minority status is typical. [1]

There are two explanations that are popular outside Germany that I now think on their own are inadequate. The first is that Germany is preoccupied by inflation as a result of the hyperinflation of the Weimar republic, and that this spills over into their attitude to government debt. (The recession of the 1930s helped create a more serious disaster, and here is a provocative account of why the memory of hyperinflation dominates.) A second idea is that Germans are culturally debt averse, and people normally note that the German for debt is also their word for guilt. The trouble with both stories is that they imply that German government debt should be much lower than in other countries, but it is not. (In 2000, the German government’s net financial liabilities as a percentage of GDP were at the same level as France, and slightly above the UK and US.)

A mistake here may be to focus too much on macroeconomics. Germany has recently introduced a minimum wage: much later than in the UK or US. I think it would be fair to say that German economists generally advised against this. In the UK and US the opinion of economists on the minimum wage issue is much more balanced, largely because there is a great deal of academic evidence that at a moderate level the minimum wage does not reduce employment significantly. So here German economics also appears to be an outlier.

Many people have heard of ordoliberalism. It would be easy to equate ordoliberalism with neoliberalism, and argue that German attitudes simply reflect the ideological dominance of neo/ordoliberal ideas. However, as I once tried to argue, because ordoliberalism recognises actual departures from an ideal of perfect markets and the need for state action in dealing with those departures (e.g. monopoly), it is potentially much more amenable to New Keynesian ideas than neoliberalism. Yet in practice ordoliberalism does not appear to allow such flexibility. It is as if in some respects economic thinking in Germany has not moved on since the 1970s: Keynesian ideas are still viewed as anti-market rather than correcting market failure, and views on the minimum wage have not taken on board market distortions like monopsony. But that observation simply prompts the question of why in these respects German economics has remained isolated from mainstream academic ideas. [2]

One of the distinctive characteristics of the German economy appears to be very far from neoliberalism, and that is co-determination: the importance of workers organisations in management, and more generally the recognition that unions play an important role in the economy. Yet I wonder whether this may have had an unintended consequence: the polarisation and politicisation of economic policy advice. The IMK is part of the Hans-Böckler-Foundation, which is linked to the German Confederation of Trade Unions. The IMK was set up in part to provide a counterweight to existing think tanks with strong links to companies and employers. If conflict over wages is institutionalised at the national level, perhaps the influence of ideology on economic policy - in so far as it influences that conflict (see footnote [1]) - is bound to be greater. 

As you can see, I remain some way from answering the question posed in the title of this post, but I think I’m a bit further forward than I was.  

[1] The ‘Hamburger Appell’ of 2005, signed by over 250 German economists, is clearly anti-Keynesian. The intellectual rationale given there is unclear, but one theme is that a more effective way of increasing employment is to increase international competitiveness by holding down domestic costs. Now if you are part of a fixed exchange rate regime or a monetary union, and you have - for institutional reasons - an ability to influence domestic wage costs that other countries that belong to the regime do not have, then it may make perfect Keynesian sense to use that instrument. This is exactly what happened (deliberately or not) from 2000 to 2007, which of course is a major reason why Germany is currently not suffering the recession being experienced by the Eurozone as a whole. (Of course, unlike a fiscal stimulus, it is a beggar my neighbour policy, because demand increases at the expense of other countries in the regime: for the regime as a whole a flexible exchange rate will offset the impact of lower costs on competitiveness.)
