In the winter 2011/12 a wave of internal capital flight prompted the ECB to abandon its exit strategy and to announce an unprecedented monetary expansion. We analyze this episode in several dimensions: (i) by providing an event-study analysis covering key variables from national central banks'...

This paper investigates the relationship between the euro-dollar exchange rate and its underlying fundamentals. First, we develop a simple theoretical model in which chartists and fundamentalists interact. This model predicts the existence of different regimes, and thus nonlinearities in the...

In this paper we investigate the effects of central bank interventions (CBI) in a noise trading model with chartists and fundamentalists. We first estimate a model in which chartists extrapolate past returns and fundamentalists forecast a mean reverting dynamics of the exchange rate towards a...

We develop a simple model of the exchange rate in which agents optimize their portfolio and use different forecasting rules. They check the profitability of these rules ex post and select the more profitable one. This model produces two kinds of equilibria, a fundamental and a bubble one. In a...

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...

The paper addresses the question what effects the enlargement of a monetary union will have on necessary structural refoms in the (low distortion) member countries and the (high distortion) candidate country. While monetary union lowers reforms in the candidate country, members of the monetary...

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...

This paper studies the design of the policy mix in a monetary union, that is, the institutional arrangement specifying the relationships between the various policymakers present in the union and the extent of their capacity of action. It is assumed that policymakers do not cooperate. Detailing...
