Government spending shocks are frequently identi?ed in quarterly time-series data by ruling out a contemporaneous response of government spending to other macroeconomic aggregates. We provide evidence that this assumption may not be too restrictive for U.S. annual time-series data.

Interest-rate spreads fluctuate widely across time and countries. We illustrate this on the basis of about 3,100 quarterly observations for 21 advanced and 17 emerging economies since the early 1990s. Prior to the financial crisis, spread fluctuations in advanced economies are an order of...

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...

Using firm-level data, we study how firm expectations adjust to news while accounting for a) the heterogeneity of news and b) the heterogeneity of firms. We classify news as either micro or macro, that is, information about firm-specific developments or information about the aggregate economy....

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...

In economies with fixed exchange rates, the adjustment to government spending shocks is asymmetric. A fiscal expansion appreciates the real exchange rate but does not stimulate output. A fiscal contraction does not alter the exchange rate, but lowers output. We develop these insights in a...
