Phase-Dependent Monetary and Fiscal Policy

This paper studies how the effects of monetary and fiscal policy vary depending on the business cycle phase. It shows that in a medium-scale DSGE model, estimated on US data, monetary policy has a stronger impact on the economy in downturns and booms. Labor and capital income taxes display similar patterns. Government expenditure shocks and consumption tax shocks, on the contrary, have a stronger impact on output in depressions and recoveries. The paper also shows that accounting for the source of business cycle fluctuations is potentially important when assessing state-dependence in policy transmission.
