| We disentangle the effects of monetary policy announcements on real economic variables into an interest rate shock component and a central bank information shock component. We identify both components using changes in interest rate futures and in exchange rates around monetary policy announcements. While the volatility of interest rate surprises declines around the Great Recession the volatility of exchange rate changes increases. Making use of this heteroskedasticity we estimate that a contractionary interest rate shock appreciates the dollar increases the excess bond premium and leads to a decline in prices and output while a positive information shock appreciates the dollar decreases prices and the excess bond premium and increases output. |
