THE CYCLICAL EFFECTS OF MONETARY POLICY REGIMES∗

A 1979 change in U.S. monetary policy coincided with a break in the cyclical behavior of monetary aggregates, while the cyclical behavior of all other real and nominal variables remained relatively constant. A model is developed to assess the quantitative importance of a change in monetary policy in accounting for these observations. The monetary authority’s reaction function is estimated conditionally on the theoretical model and accounts for upward of 72–95% of all observed changes, including inside money preceding the business cycle and a qualitative change in the cyclical behavior of the monetary base.
