Self-Fulfilling Crises in the Eurozone: An Empirical Test. CEPS Working Document No. 366, 22 June 2012

This paper tests the hypothesis that government bond markets in the eurozone are more fragile and more susceptible to self-fulfilling liquidity crises than in stand-alone countries. We find evidence that a significant part of the surge in the spreads of the PIGS countries (Portugal, Ireland, Greece and Spain) in the eurozone during 2010-11 was disconnected from underlying increases in the debt-to-GDP ratios and fiscal space variables, and was the result of negative self-fulfilling market sentiments that became very strong since the end of 2010. We argue that this can drive member countries of the eurozone into bad equilibria. We also find evidence that after years of neglecting high government debt, investors became increasingly worried about this in the eurozone, and reacted by raising the spreads. No such worries developed in stand-alone countries despite the fact that debt-to-GDP ratios and fiscal space variables were equally high and increasing in these countries.

A simple model of multiple equilibria and default. CEPS Working Document No. 366, 16 July 2012

This Working Document by Daniel Gros presents a simple model that incorporates two types of sovereign default cost: first, a lump-sum cost due to the fact that the country does not service its debt fully and is recognised as being in default status, by ratings agencies, for example. Second, a cost that increases with the size of the losses (or haircut) imposed on creditors whose resistance to a haircut increases with the proportional loss inflicted upon them. One immediate implication of the model is that under some circumstances the creditors have a (collective) interest to forgive some debt in order to induce the country not to default. The model exhibits a potential for multiple equilibria, given that a higher interest rate charged by investors increases the debt service burden and thus the temptation to default. Under very high debt levels credit rationing can set in as the feedback loop between higher interest rates and the higher incentive to default can become explosive. The introduction of uncertainty makes multiple equilibria less likely and reduces their range.

Breaking down the barriers to firm growth in Europe: The fourth EFIGE policy report. Bruegel Blueprint 18, 28 August 2012

Large firms contribute disproportionately to the economic performance of countries: they are more productive, pay higher wages, enjoy higher profits and are more successful in international markets. The differences between European countries in terms of the size of their firms are stark. Firms in Italy and Spain, for example, are on average 40 percent smaller than firms in Germany. The low average firm size translates into a chronic lack of large firms. In Italy and Spain, a mere 5 percent of manufacturing firms have more than 250 employees, compared to a much higher 11 percent in Germany. Understanding the roots of these differences is key to improving the economic performance of Europe’s lagging economies. So why is there so much variation in firm size in different European countries? What are the barriers that keep firms in some countries from growing? And which policies are likely to be most effective in breaking down those barriers? This policy report aims to answer these questions by developing a quantitative model of the seven European countries covered by the EFIGE survey (Austria, France, Germany, Hungary, Italy, Spain and the UK). The EFIGE survey asked 14,444 firms in those countries about their performance, their modes of internationalisation, their staffing decisions, their financing structure, and their competitive environment, among other topics.

A sovereign wealth fund to lift Germany's curse of excess savings. CEPS Policy Brief No. 280, 28 August 2012

As an alternative to the present system of intermediation of the German savings surplus, this paper suggests that the risk-adjusted rate of return could be improved by creating a sovereign wealth fund for Germany (designated DESWF), which could invest excess German savings globally. Such a DESWF would offer German savers a secure vehicle paying a guaranteed positive minimum real interest rate, with a top-up when real investment returns allowed. The vehicle would invest the funds in a portfolio that is highly diversified by geography and asset classes. Positive real returns can be expected in the long run based on positive real global growth. Since, in this case, a significant amount of funds would flow outside the euro area, the euro would depreciate, which would help crisis countries presently struggling to revive growth through exports and to close their external deficits so as to recoup their international credit-worthiness. Target imbalances would gradually disappear and German claims abroad would move from nominal claims on the ECB to diversified real and nominal claims on various private and public foreign entities in a variety of asset classes.
