We lay out an empirical and a theoretical model to analyze the effects of non-fundamental exchange rate volatility on economic activity and welfare. In the first part of the paper, the GARCH-SVARmodel is applied to measure empirically the effect of the conditional exogenous exchange rate...

This paper shows that the credibility gain from permanently committing to a fixed exchange rate by joining the European Monetary Union can outweigh the loss from giving up independent monetary policy. When the central bank enjoys only limited credibility a pegged exchange rate regime yields a...

The globalization of capital and product markets has many implications for economic welfare. Countries can specialize in the production of goods for which they have comparative advantages, and capital is allocated more efficiently. However, one potentially adverse effect of globalization is the...

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 model to analyze the consequences of international capital mobility for the effectiveness of monetary policy in open economies. The model shows that the substitutability of goods produced in different countries plays a central...

This paper discusses whether the integration of international financial markets affects business cycle fluctuations. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock....

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...

This paper uses a dynamic general equilibrium two-country optimizing model to analyze the consequences of international capital mobility for the effects of monetary policy in open economies. The model shows that the difference between the short-run output effects of monetary policy shocks in a...

This paper uses a dynamic general equilibrium two-country optimizing 'new-open economy macroeconomics? model to analyze the consequences of international capital mobility for the effectiveness of fiscal policy. Conventional wisdom suggests that higher capital mobility diminishes the...
