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 analyze the impact of Eurozone/Germany and U.S. macroeconomic news announcements and the communication of the monetary policy settings of the ECB and the Fed on the forex markets of new EU members. We employ an event study methodology to analyze intra-day data from 2011-2015. Our...

This paper investigates the relationship between real exchange rate changes and the German, French and UK automobile and mechanical engineering sector. In stylized models, exports decline whenever the domestic currency appreciates and vice versa. Strategic firm behavior, however, can obscure the...

How do trade costs affect international trade? This paper offers a new approach. We rely on a flexible gravity equation that predicts variable trade cost elasticities, both across and within country pairs. We apply this framework to the effect of currency unions on international trade. While we...

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous...

This paper argues that the Eurozone crisis stems from a risk management failure in the Eurosystem's design, and that applying insurance theory is useful. We model risk neutral agents choosing portfolios of government bonds of n countries in a monetary union and other assets. We firstly analyse a...

The euro area will not have a centralised budget and smoothing of country-specific asymmetric shocks via private financial markets will develop only slowly. Mistrust among the governments has caused rigid, even pro-cyclical fiscal policies. Smoothing mechanisms are absent due to the fear that...

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...
