We critically review the recent literature on currency unions, and discuss the methodological challenges posed by the empirical assessment of their costs and benefits. In the process, we provide evidence on the economic effects of the euro. In particular, and in contrast with estimates of the...

A two-country model with monopolistic competition and price stickiness is employed to investigate the implications for macroeconomic stability and the welfare properties of three international policy arrangements: (a) cooperative, (b) non-cooperative and (c) monetary union. I characterize the...

This study analyzes a two-country dynamic general equilibrium model with nominal rigidities, monopolistic competition and producer currency pricing. A quadratic approximation to the utility of the consumers is derived and assumed as the policy objective function of the policymakers. It is shown...

This paper presents a new argument for international monetary policy coordination based on considerations of structural asymmetries across countries. In a two-country world with a traded and a non-traded sector in each country, optimal independent monetary policy cannot replicate the...

We examine the impact of US monetary policy shocks on exchange rates using the monetary policy indicator proposed by Bernanke and Mihov [Quarterly Journal of Economics, 113 (1998) 869–902]. We find evidence for instantaneous, rather than delayed, US dollar overshooting after a monetary shock...

We investigate the possible existence of asymmetries among Euro Area countries reactions to the European Central Bank monetary policy. Our analysis is based on a Structural Dynamic Factor model estimated on a large panel of quarterly variables including data on the aggregate Euro Area, as well...

We analyze a dual currency search model in which agents are allowed to hold multiple units of both currencies. Hence, agents hold portfolios of currency. We study equilibria in which the two currencies are identical and equilibria in which the two currencies differ according to the magnitude of...

We study how constrained fiscal policy can affect regional inflation and output in a two-region model of a monetary union with sticky prices and distortionary taxation. Both government expenditure and taxes can be used to stabilize regional variables; however, the best welfare outcome is...

What are the macroeconomic implications of changes in sovereign risk premia? In this paper, I use a novel identification strategy coupled with a new dataset for the Euro Area to answer this question. I show that exogenous innovations in sovereign risk premia were an important driver of the...
