This paper examines how segmented asset markets can generate real and nominal effects of monetary policy. I develop a model, in which varieties of consumption bundles are purchased sequentially. Newly injected money thus disseminates slowly through the economy via second-round effects and...

This paper provides an explanation for the observed decline of the exchange rate pass-through into import prices by modeling the effects of financial market integration on the optimal choice of the pricing currency in the context of rigid nominal goods prices. Contrary to previous literature,...

This paper examines the effects of expansionary technology shocks (shocks that increase labor productivity and factor inputs) as opposed to contractionary technology shocks (shocks that increase labor productivity, but decrease factor inputs). We estimate these two shocks jointly based on a...

In contrast to the notion that the exchange-rate regime is non-neutral, there is little evidence that EMU has systematically changed the European business cycle. In fact, we find the volatility of macroeconomic variables largely unchanged before and after the introduction of the euro. Exceptions...

In this paper we analyze European business cycles before and under EMU. Across the two periods we find 1) a significant decline in real exchange rate volatility, 2) significant changes in cross-country correlations, and 3) the volatility of macroeconomic fundamentals largely unchanged. We...

In this paper we analyze European business cycles before and under EMU. Across the two periods we ?nd 1) a signi?cant decline in real exchange rate volatility, 2) signi?cant changes in cross-country correlations, and 3) the volatility of macroeconomic fundamentals largely un- changed. We develop...

Expectations matter for economic activity. To the extent that they are fundamentally unwarranted, they represent "undue optimism or pessimism" (Pigou, 1927). In this paper, we identify empirically the effect of undue optimism/pessism ("optimism shocks") on economic activity. In a first step, we...

Using vector autoregressions on U.S. time series relative to an aggregate of industrialized countries, this paper provides new evidence on the dynamic effects of government spending and technology shocks on the real exchange rate and the terms of trade. To achieve identification, we derive...
