We show in a dynamic stochastic general equilibrium framework that the introduction of a common currency by a group of countries with only partially integrated goods markets, incomplete …nancial markets and no labor migration across member states, signi…cantly increases volatility of...

In the data, individual prices change frequently and by large amounts. In standard sticky price models, frequent and large price changes imply a fast response of the aggregate price level to nominal shocks. This paper presents a model in which price setting firms optimally decide what to...

We decompose by origin the sources of the variation in real aggregate output and aggregate price level in the Czech Republic, Hungary and Poland. We find that a sizable fraction of the variation is attributable to external shocks, especially so for aggregate price level. We show that euroarea...

In recent policy debates some have argued that expansionary monetary policy in Japan can increase real output in Japan and in Japan´s neighbors, while others have warned that it is a beggar-thy-neighbor policy. In this paper we estimate structural vector autoregressions to assess the effects of...

Using structural VARs, I find that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect quickly and strongly interest rates and the exchange rate in a typical emerging market. The price level and real output in...

In this paper we investigate the labor market dynamics in a matching model where fluctuations are driven by movements in the discount factor. A comparison with the standard productivity shock is provided. Movements in the discount factor can be used as a proxy for variations in financial risks,...
