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...

Using industry-level data, this paper shows that the European transition region benefited much more strongly from financial integration in terms of economic growth than other developing countries in the years preceding the current crisis. We analyze several factors that may explain this finding:...

This paper analyses the tendency for nations to break up as a result of a trade-off between the aggregate efficiency losses from separation and the redistributive gains to the majority, which can occur in all regions, even when there are no transfers across these regions. We show that...

This paper analyzes the macroeconomic consequences of the establishment of a monetary union in the presence of unionized labour markets. It is shown that the effects of the formation of a monetary union depend on several labour market features, such as the degree of centralization of wage...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyse its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

This paper investigates the importance of fiscal policy in providing macroeconomic stabilisation in a monetary union. We use a microfounded New Keynesian model of a monetary union which incorporates persistence in inflation and non-Ricardian consumers, and derive optimal simple rules for fiscal...

The paper explores the case for monetary and fiscal unification. Monetary policy suffers from an inflation bias because the monetary authorities are not able to commit. With international risk-sharing in a fiscal union, fiscal discipline suffers from moral hazard. An inflation target alleviates...

The main conclusions of this paper are the following. In order to minimize switching costs, the name of the new EU currency should be the Deutschmark. Differential national requirements for seigniorage revenue provide a weak case for retaining national monetary independence. From the point of...

How does a monetary union work when labour markets are heterogeneous? Since shocks are transmitted via both trade links and the common monetary policy and propagated via labour market responses, it follows that labour market institutions may have not only national but also union-wide...

This Paper analyses the interaction between a common monetary policy and differentiated labour market institutions. We develop a model of a two country monetary union. In each country, labour market institutions are distinguished by the degree of centralization in wage bargaining. In each...
