We study the importance of uncertainty and public finance to the welfare ranking of three environmental policy instruments: pollution taxes, pollution permits and Kyoto-like numerical rules for emissions. The setup is the basic stochastic neoclassical growth model augmented with the assumptions...

In this paper, we study the aggregate and distributional implications of a smaller public sector in the euro area. By a smaller public sector, we mean a reduction in public debt and/or cuts in public spending, when such changes in fiscal policy are accommodated by adjustment in various taxes....

We test the hypothesis that the 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 in the Eurozone during...

The sovereign debt crisis has made it clear that central banking is more than keeping inflation low. Central banks are also responsible for financial stability. An essential tool in maintaining financial stability is provided by the capacity of the central bank to be the lender of last resort in...

When entering a monetary union, member-countries change the nature of their sovereign debt in a fundamental way (e.g., they cease to have control over the currency in which their debt is issued). As a result, financial markets can force these countries' sovereigns into default. In this sense,...

We analyze the similarities and the differences in the fragility of the European Monetary system (EMS) and the Eurozone. We test the hypothesis that in the EMS the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets while in the Eurozone it was...

In this paper we suggest that Eurozone countries face a policy trade-off among: 1) a common rule imposing co-movements in fiscal policy; 2) financial stability; and 3) financial integration. We provide empirical evidence documenting the existence of such a trade-off in the period characterized...

This contribution develops a blueprint for a European fiscal union. We argue that a viable European fiscal union can be constructed without joint liability for public debt or a centralized government with a large common budget. Such a fiscal union should combine elements of market discipline...

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous...

In this paper we provide empirical evidence documenting the nature of the Eurozone's fragility. We find that during periods of turmoil, financial markets have tended to impose strong programs of austerity on member countries of the Eurozone. This confirms the evidence we found in a previous...
