Building on Calvo (1988), we develop a stochastic monetary economy in which government default may be driven by either self-fulfilling expectations or weak fundamentals, and explore conditions under which central banks can rule out the former. We analyze monetary backstops resting on the ability...

Sovereign risk premia in several euro area countries have risen markedly since 2008, driving up credit spreads in the private sector as well. We propose a New Keynesian model of a two-region monetary union that accounts for this "sovereign risk channel." The model is calibrated to the euro area...

During the global financial crisis 2007--2009 fiscal policy was widely used as a stabilization tool. Policymakers allowed a large build-up of public debt resulting from both automatic and discretionary expansionary measures. At the same time, calls for policy coordination stressed that...

The paper develops a simple choice-theoretic model suitable for carrying out welfare" analyses of the international transmission of monetary and fiscal policies. The model can be" solved in closed form and illustrated in terms of the simplest graphical apparatus provide the analysis of...

This paper analyzes the welfare implications of international spillovers related to productivity gains, changes in market size, or government spending. We introduce trade costs and endogenous varieties in a two-country general-equilibrium model with monopolistic competition, drawing a...

In this Paper we show that a currency area can be a self-validating optimal policy regime, even when monetary unification does not foster real economic integration and intra-industry trade. This is because profit-maximizing producers in a currency area adopt endogenous pricing strategies that...

We analyze the policy trade-offs generated by local currency price stability of imports in economies where upstream producers strategically interact with downstream firms selling the final goods to consumers. We study the effects of staggered price setting at the downstream level on the optimal...

We analyse the arguments in favour and against binding fiscal rules such as those recently agreed by European countries as preconditions for participation in the third phase of the European Monetary Union. The evidence in the paper suggests that a number of EC countries are following...

This paper builds a baseline two-country model of real and monetary transmission in the presence of optimal international price discrimination by firms. Distributing traded goods to consumers requires nontradables, intensive in local labor. Because of distributive trade the price elasticity of...
