In a monetary union, the interaction between several governments and a single central bank is plagued by several sources of deficit bias, including common pool problems. Each government has strong preferences over local spending and taxation but suffers only part of the costs of union-wide...

It is widely debated whether a monetary union has to be accompanied by a fiscal transfer scheme to accommodate asymmetric shocks. We build a model of a monetary union with a central bank and two heterogeneous countries that are linked by a fiscal transfer scheme with repercussions on monetary...

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...

Labor mobility is commonly taken as a property of an optimal currency area. But how does that property affect the outcome of fiscal policies? In our model, we show that perfect (costless) labour mobility is not necessarily welfare improving, since it prevents the national fiscal authorities from...

In the wake of the euro area crisis, the debate on instruments to deepen economic integration among its members has intensified, among others putting forward a fiscal stabilization capacity for EMU members. Contributions made so far to further this idea have mostly concentrated on the...

Fiscal federalism may not be a panacea in a monetary union if it does not address the non-cooperative behaviour between fiscal policymakers. To prove this, we assess the relative merits of a fiscal federalism scheme in a monetary union and intergovernmental fiscal cooperation without such a...

We assess the role of national fiscal policies, as automatic stabilizers, within a monetary union. We use a two-country New Keynesian DGE model which incorporates non-Ricardian consumers (as in Gali et al. 2004) and a home bias in the composition of national consumption bundles. We find that...

The paper examines the monetary-fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. We first show that monetary uncertainty disciplines fiscal policymakers and thereby reduces taxes, average inflation and output distortions. However, as more...

This paper employs a stylized New Keynesian DSGE model for a monetary union to analyze whether cyclical inflation differentials can be explained by cross-country differences concerning the characteristics of financial markets. Our results suggest that empirically plausible degrees of...

Against the backdrop of the Greek three-act tragedy, we present a theoretical framework for studying Greece's recent debt and currency crisis. The model is built on two essential blocks: first, erratic macroeconomic policymaking in Greece is described using a stochastic regime-switching model;...
