The interaction of fiscal and monetary policy during this period has also been the subject of much discussion and analysis. This paper gives new insight into past fiscal policy and its influence on monetary policy by examining the U.S. Federal Reserve Board staff’s Greenbook forecasts of fiscal policy. The authors create a real-time database of the Greenbook forecasts of fiscal policy, examine the forecast performance in terms of bias and efficiency, and explore the implications for the interaction of fiscal policy and monetary policy. The authors also attempt to provide advice for fiscal policy by showing how policymakers learn over time about the trajectory of the U.S. federal government’s fiscal balance as well as the changing roles of structural and cyclical factors.
