Mr Sinn on EMU Core Countries’ Inflation

December 17, 2014 16 comments

Two weeks ago I received a request from Prof Sinn to make it known to my readers that he feels misrepresented by my post of September 29. Here is his very civilized mail, that I publish with his permission:

Dear Mr. Saraceno,
I have just become acquainted with your blog: You misrepresent me here. In my book The Euro Trap. On Bursting Bubbles, Budgets and Beliefs, Oxford University Press 2014, and in many other writings, I advise against extreme deflation scenarios for southern Europe because of the grievous effects upon debtors. I explicitly draw the comparison with Germany in the 1929 – 1933 period. I advocate instead a mixed solution with moderate deflation in southern Europe and  more inflation in northern Europe,  Germany in particular. In addition, I advocate a debt conference for southern Europe and a “breathing currency union” which allows for temporary exits of those southern European countries for which the stress of an internal adjustment would be unbearable. You may also wish to consult my paper “Austerity, Growth and Inflation: Remarks on the Eurozone’s Unresolved Competitiveness Problem”, The World Economy 37, 2014, p. 1-1,, in which I also argue for more inflation in Germany to solve the Eurozone’s problem of distorted relative prices.  I would be glad if you could make this response known to your readers.

Sincerely yours
Hans-Werner Sinn
Professor of Economics and Public Finance
President of CESifo Group

I was swamped with end of semester duties, and I only managed to read the paper (not the book) this morning. But in spite of Mr Sinn’s polite remarks, I stand by my statement (spoiler alert: the readers will find very little new content here). True, in the paper Mr Sinn advocates some inflation in the core (look at sections 9 an 10). In particular, he argues that

What the Eurozone needs for its internal realignment is a demand-driven boom in the core countries. Such a boom would also increase wages and prices, but it would do so because of demand rather that supply effects. Such demand-driven wage and price increases would come through real and nominal income increases in the core and increasing imports from other countries, and at the same time, they would undermine the competitiveness of exports. Both effects would undoubtedly work to reduce the current account surpluses in the core and the deficits in the south.

This is a diagnosis that we share But the agreement stops around here. Where we disagree is on how to trigger the demand-driven boom. Mr Sinn expects this to happen thanks to market mechanisms, just because of the reversal of capital flows that the crisis triggered. He argues that the capital which foolishly left Germany to be invested in peripheral countries, being repatriated would trigger an investment and property boom in Germany, that would reduce German’s current account surplus. This and this alone would be needed. Not a policy of wage increases, useless, nor a fiscal expansion even more useless.

Problem is, the data speak against Mr Sinn’s belief. Since the crisis hit, capital massively left peripheral countries, and yet this did not fuel domestic demand in Germany. Last August I showed the following figure:


It shows that after a drop (in the acute phase of the financial crisis) due to a sharp decline of GDP, since 2009 domestic demand as a percentage of GDP kept decreasing, in Germany as well as in the rest of the Eurozone. The reversal of capital flows depressed demand in the periphery, but did not boost it in Germany. Mr Sinn is too skilled an economist to fail to see this. The reason is, of course, that the magic investment boom did not happen:

2014_12_17_Sinn_1Mr Sinn, being a fine economist, could object that this is because GDP, the denominator, grew more fell less in Germany than in the rest of the EMU. Well, think again.

2014_12_17_Sinn_2Yes, France comes out as investing (privately) less than Germany. But we are far from an investment boom in Germany as well. Mr Sinn, will agree, I ma sure.

What basically happened, I said it before, is that adjustment was not symmetric. Peripheral countries reduced their excess demand, while Germany and the core did not reduce their excess savings. The result is that, if we compare 2007 to 2014, external imbalances of the periphery were greatly reduced or reversed, while with the exception of Finland the core did not do its homework:

2014_12_17_Sinn_0The EMU as a whole became a large Germany, running a current account surplus (it was more or less in balance in 2007), and relying on its exports for growth. A very dubious strategy in the long run.

The conclusion in my opinion is one and only one: We cannot count on markets alone, in the current macroeconomic situation, if we want rebalancing to take place. In the article he suggested I read, Mr Sinn states that a 4 or 5 per cent inflation rate would be politically impossible to sell to the German public:

Moreover, it is unclear whether the German population would accept being deprived of their savings. Given the devastating experiences Germany made with hyperinflation from 1914 to 1923, which in the end undermined the stability of its society, the resistance against an extended period of inflation in Germany could be as strong or even stronger than the resistance against deflation in southern Europe. After all, a rate of 4.1 per cent for German inflation for 10 years, which would be necessary to allow the necessary realignment between France and Germany without France sliding into a deflation, would mean that the German price level would increase by 50 per cent and that, in terms of domestic goods, German savers would be deprived of 33 per cent of their wealth. If the German inflation rate were even 5.5 per cent, which would be necessary to accommodate the Spanish realignment without price cuts, its price level would increase by 71 per cent over a decade and German savers would be deprived of 42 per cent of their wealth.

This shows all the logic of Ordoliberalism: It is impossible to sell inflation to the the German public, because this would deprive them of their savings. This argument only makes sense if one subscribes to the Berlin View that the bad guys in the south partied with hard earned money of northern (hard) workers. Otherwise the argument makes no sense at all, as high inflation in the core for next few years simply  compensates low inflation in the past. Should I remind Mr Sinn that the outlier in terms of labour costs  is not the EMU periphery, but Germany?

Also, I find it disturbing that, while acknowledging that inflation in Germany would be needed, Mr Sinn rejects it on the ground that it would be a hard sell. The role of intellectuals and academics is mostly to discuss, find solutions (or at least try), and then argue for them. All the more so if this is unpopular, because it is then that their pedagogical role is most needed. All too often public intellectuals abdicate to their role, and simply follow the trend. Should we all argue in favour of a euro breakup only because public opinion is less and less favorable to the single currency?

Finally, a short comment on another bit of Mr Sinn’s article:

And although the core countries would suffer [from high inflation], the solution would not be comfortable for the devaluating countries either. They will unavoidably face a long-lasting stagnation with rising mass unemployment and increasing hardship for the population at large. People will turn away from the European idea, and voices opting for exiting the euro will gain strength. Thus, it might be politically impossible to induce the necessary differential inflation in the Eurozone.

I don’t really see his point here. But let’s take it for good, just for the sake of argument. I think it is too late to worry about support for the euro in the periphery. It is hard to see how “excessive” inflation in the core would impose more hardness than seven years of adjustment, ill-conceived structural reforms, and self-defeating austerity.

So Mr Sinn, thank you for your mail and for the reference to your paper that I have read with interest. But no, I don’t think I misrepresented you.  The core of your argument remains that the burden of adjustment should rest on the periphery’s shoulders. And you failed to convince me that this is right.
