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.

Labour Costs: Who is the Outlier?

September 11, 2014 29 comments

Spain is today the new model, together with Germany of course, for policy makers in Italy and France. A strange model indeed, but this is not my point here. The conventional wisdom, as usual, almost impossible to eradicate, states that Spain is growing because it implemented serious structural reforms that reduced labour costs and increased competitiveness. A few laggards (in particular Italy and France) stubbornly refuse to do the same, thus hampering recovery across the eurozone. The argument is usually supported by a figure like this


And in fact, it is evident from the figure that all peripheral countries diverged from the benchmark, Germany, and that since 2008-09 all of them but France and Italy have cut their labour costs significantly. Was it costly? Yes. Could convergence have made easier by higher inflation and wage growth in Germany, avoiding deflationary policies in the periphery? Once again, yes. It remains true, claims the conventional wisdom,  that all countries in crisis have undergone a painful and necessary adjustment. Italy and France should therefore also be brave and join the herd.

Think again. What if we zoom out, and we add a few lines to the figure? From the same dataset (OECD. Productivity and ULC By Main Economic Activity) we obtain this:


It is unreadable, I know. And I did it on purpose. The PIIGS lines (and France) are now indistinguishable from other OECD countries, including the US. In fact the only line that is clearly visible is the dotted one, Germany, that stands as the exception. Actually no, it was beaten by deflation-struck Japan. As I am a nice guy, here is a more readable figure:


The figure shows the difference between change in labour costs in a given country, and the change in Germany (from 1999 to 2007). labour costs in OECD economies increased 14% more than in Germany. In the US, they increased 19% more, like in France, and slightly better than in virtuous Netherlands or Finland. Not only Japan (hardly a model) is the only country doing “better” than Germany. But second best performers (Israel, Austria and Estonia) had labour costs increase 7-8% more than in Germany.

Thus, the comparison with Germany is misleading. You should never compare yourself with an outlier! If we compare European peripheral countries with the OECD average, we obtain the following (for 2007 and 2012, the latest available year in OECD.Stat)


If we take the OECD average as a benchmark, Ireland and Spain were outliers in 2007, as much as Germany; And while since then they reverted to the mean, Germany walked even farther away. It is interesting to notice that unreformable France, the sick man of Europe, had its labour costs increase slightly less than OECD average.

Of course, most of the countries I considered when zooming out have floating exchange rates, so that they can compensate the change in relative labour costs through exchange rate variation. This is not an option for EMU countries. But this means that it is even more important that the one country creating the imbalances, the outlier, puts its house in order. If only Germany had followed the European average, it would have labour costs 20% higher than their current level. There is no need to say how much easier would adjustment have been, for crisis countries. Instead, Germany managed to impose its model to the rest of the continent, dragging the eurozone on the brink of deflation.

What is enraging is that it needed not be that way.

Blame the World?

August 15, 2014 12 comments

Yesterday’s headlines were all for Germany’s poor performance in the second quarter of 2014 (GDP shrank of 0.2%, worse than expected). That was certainly bad news, even if in my opinion the real bad news are hidden in the latest ECB bulletin, also released yesterday (but this will be the subject of another post).

Not surprisingly, the German slowdown stirred heated discussion. In particular Sigmar Gabriel, Germany’s vice-chancellor, blamed the slowdown on geopolitical risks in eastern Europe and the Near East. Maybe he meant to be reassuring, but in fact his statement should make us all worry even more. Let me quote myself (ach!), from last November:

Even abstracting from the harmful effects of austerity (more here), the German model cannot work for two reasons: The first is the many times recalled fallacy of composition): Not everybody can export at the same time. The second, more political, is that by betting on an export-led growth model Germany and Europe will be forced to rely on somebody else’s growth to ensure their prosperity. It is now U.S. imports; it may be China’s tomorrow, and who know who the day after tomorrow. This is of course a source of economic fragility, but also of irrelevance on the political arena, where influence goes hand in hand with economic power. Choosing the German economic model Europe would condemn itself to a secondary role.

I have emphasized the point I want to stress, once again, here: adopting an export-led model structurally weakens a country, that becomes unable to find, domestically, the resources for sustainable and robust growth. And here we are, the rest of the world sneezes, and Germany catches a cold. The problem is that we are catching it together with Germany:


The ratio of German GDP over domestic demand has been growing steadily since 1999 (only in 19 quarters out of 72, barely a third, domestic demand grew faster than GDP). And what is more bothersome is that since 2010 the same model has been  adopted by imposed to the rest of the eurozone. The red line shows the same ratio for the remaining 11 original members of the EMU, that was at around one for most of the period, and turned frankly positive with the crisis and implementation of austerity.It is the Berlin View at work, brilliantly and scaringly exposed by Bundesbank President Jens Weidmann just a couple of days ago. We are therefore increasingly dependent on the rest of the world for our (scarce) growth (the difference between the ratio and 1 is the current account balance).

It is easy today to blame Putin, or China, or tapering, or alien invasions, for our woes.  Easy but wrong. Our pain is self-inflicted. Time to change.

Fiscal Expansion or What?

January 21, 2014 4 comments

The newly born Italian magazine Pagina99 published a piece I wrote on rebalancing in Europe after the German elections. Here is an English version.

The preliminary estimates for 2013 released by the German Federal Statistical Office, depict a mixed picture. Timid signs of revival in domestic demand do not seem able to compensate for the slowdown in exports to other countries in the euro zone, still mired in weak or negative growth rates. The German economy does not seem able to ignore the economic health of its European partners. In spite of fierce resistance of Germany policymakers, there is increasing consensus that the key to a durable exit from the Eurozone crisis can only be found in restoring symmetry in the adjustment following the crisis. The reduction of expenditure and deficits in the Eurozone periphery, that is currently happening, needs to be matched by an increase of expenditure and imports by the core, in particular by the Netherlands and Germany (Finland and Austria have actually drastically reduced their trade surpluses). In light of the coalition agreement signed by the CDU and the SPD, it seems unlikely that major institutional innovation will happen in the Eurozone, or that private demand in Germany will increase sufficiently fast to have an impact on imbalances at the aggregate level. This leaves little alternative to an old-fashioned fiscal expansion in Germany.

The Eurozone reaction to the sovereign debt crisis, so far, has focused on enhancing discipline and fiscal restraint. Germany, the largest economy of the zone, and its largest creditor, was pivotal in shaping this approach to the crisis. The SPD, substantially shared the CDU-Liberal coalition view that the crisis was caused by fiscal profligacy of peripheral member countries, and that little if any risk sharing should be put in place (be it a properly functioning banking union, or some form of debt mutualisation). The SPD also seems to support Mrs Merkel’s strategy of discretely looking elsewhere when the ECB is forced to stretch its mandate to respond to exceptional challenges, while refusing all discussion on introducing the reform of the bank statute in a wider debate on Eurozone governance. This consensus explains why European matters take relatively little space in the 185 pages coalition agreement.

This does not mean that the CDU-SPD government will have no impact on Eurozone rebalancing. The most notable element of the coalition agreement is the introduction of a minimum wage that should at least partially attenuate the increasing dualism of the German labour market. This should in turn lead, together with the reduction of retirement age to 63 years, to an increase of consumption. The problem is that these measures will be phased-in slowly enough for their macroeconomic impact to be diluted and delayed.

Together with European governance, the other missing character in the coalition agreement is investment; this is surprising because the negative impact of the currently sluggish investment rates on the future growth potential of the German economy is acknowledged by both parties; yet, the negotiations did not include direct incentives to investment spending. The introduction of the minimum wage, on the other hand, is likely to have conflicting effects. On the one hand, by reducing margins, it will have a negative impact on investment spending. But on the other, making labour more expensive, it could induce a substitution of capital for labour, thus boosting investment. Which of these two effects will prevail is today hard to predict. But it is safe to say that changes in investment are not likely to be massive.

To summarize, the coalition agreement will have a small and delayed impact on private expenditure in Germany. Similarly, the substantial consensus on current European policies, leaves virtually no margin for the implementation of rebalancing mechanisms within the Eurozone governance structure.

Thus, there seems to be little hope that symmetry in Eurozone rebalancing is restored, unless the only remaining tool available for domestic demand expansion, fiscal policy, is used. The German government should embark on a vast fiscal expansion program, focusing on investment in physical and intangible capital alike. There is room for action. Public investment has been the prime victim of the recent fiscal restraint, and Germany has embarked in a huge energetic transition program that could be accelerated with beneficial effects on aggregate demand in the short run, and on potential GDP in the long run. Finally, Germany’s public finances are in excellent health, and yields are at an all-times low, making any public investment program short of pure waste profitable. Besides stubbornness and ideology, what retains Mrs Merkel?
