We assess how firm expectations about future production impact current production and pricing decisions. Our analysis is based on a large survey of firms in the German manufacturing sector. To identify the causal effect of expectations, we rely on the timing of survey responses and match firms...

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...

This paper examines the implications of segmented assets markets for the 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...

We assess the contribution of "undue optimism" (Pigou) to short-run fluctuations. In our analysis, optimism pertains to total factor productivity which determines economic activity in the long run, but is not contemporaneously observed by market participants. In order to recover optimism shocks...

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...

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...
