The Effects of Foreign Shocks when Interest Rates are at Zero
In a two-country DSGE model, the effects of foreign demand shocks on the home country are greatly amplified if the home economy is constrained by the zero lower bound on policy interest rates. This result applies even to countries that are relatively closed to trade such as the United States. Departing from many of the existing closed-economy models, the duration of the liquidity trap is determined endogenously. Adverse foreign shocks can extend the duration of the trap, implying more contractionary effects for the home country. The home economy is more vulnerable to adverse foreign shocks if ...

Monetary policy through production networks: evidence from the stock market
Monetary policy shocks have a large impact on stock prices during narrow time windows centered around press releases by the FOMC. We use spatial autoregressions to decompose the overall effect of monetary policy shocks into a direct effect and a network effect. We attribute 50 to 85 percent of the overall impact to network effects. The decomposition is a robust feature of the data, and we confirm large network effects in realized cash-flow fundamentals. A simple model with intermediate inputs allows a structural interpretation of our empirical strategy. Our findings indicate that production ...
