Estimates of US monetary policy rules with allowance for changes in the output gap

This article estimates a reduced form Taylor rule for the Pre-Volcker and Volcker-Greenspan periods. A novelty is that it follows a suggestion of Walsh and includes changes in the output gap as an explanatory variable. Either this variable or an interaction term between inflation and changes in the output gap are highly significant in both periods. The response to inflation and the interaction term are higher in the Volcker-Greenspan period of office.
