We study the impact of several Covid-19 related supply shocks. We use a standard wage setting-price setting model of the labor market and analyze the transmission of the shocks to the natural rate of unemployment and production. In a first step, the shocks are analyzed in a general way,...

This paper uses a 'new open economy macroeconomics' model to study the effect of a productivity shock on exchange rate dynamics. The special features of the model are that households' preferences exhibit a 'catching up with the Joneses' effect and that international financial markets are...

Results of empirical research have revealed a characteristic hump-shaped effect of monetary policy shocks on output: the effect builds to a peak after several months and then gradually dies out. We analyze, in the context of a "new open economy macroeconomics" model, factors that imply a hump-...

This paper uses a dynamic general equilibrium optimizing two-country model to analyze how the formation of exchange rate expectations shapes the effects of monetary policy shocks in open economies. The model implies that the short-run output effects of permanent monetary policy shocks diminish...

This paper uses a dynamic general equilibrium two-country optimizing sticky-price model to analyze the consequences of international financial market integration for the propagation of asymmetric productivity shocks in a monetary union. The model implies that business cycle volatility is higher...

A number of empirical studies have reported the result that exchange rates show a delayed overshooting in response to monetary policy shocks. This result is puzzling. Economic theory suggests that the overshooting should occur immediately after the shock, not with a delay. This paper uses a ?new...
