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...

We assess how survey expectations impact production and pricing decisions on the basis of a large panel of German firms. We identify the causal effect of expectations by matching firms with the same fundamentals but different views about the future. The probability to raise (lower) production is...

Interest-rate spreads fluctuate widely across time and countries. We characterize their behavior using some 3,200 quarterly observations for 21 advanced and 17 emerging economies since the early 1990s. Before the financial crisis, spreads are 10 times more volatile in emerging economies than in...

"Big G" typically refers to aggregate government spending on a homogeneous good. In this paper, we open up this construct by analyzing the entire universe of procurement contracts of the US government and establish five facts. First, government spending is granular, that is, it is concentrated...

Under fixed exchange rates, fiscal policy is an effective tool. According to classical views because it impacts the real exchange rate, according to Keynesian views because it impacts output. Both views have merit because the effects of government spending are asymmetric. A spending cut lowers...

Country-specific business cycle fluctuations are potentially very costly for member states of currency unions because they lack monetary autonomy. The actual costs depend on the extent to which consumption is shielded from these fluctuations and thus on the extent of risk sharing across member...
