with Eric Sims: w19749
This paper studies the state-dependence of the output and welfare effects of shocks to government purchases in a canonical medium scale DSGE model. When monetary policy is characterized by a Taylor rule, the output multiplier (the change in output for a one unit change in government spending) is countercyclical but close to constant across states of the business cycle, whereas the welfare multiplier (the consumption equivalent change in a measure of aggregate welfare for the same change in government spending) is quite volatile and procyclical. These results are robust to different means of fiscal finance. When the nominal interest rate is unresponsive to economic conditions, such as would be the case at the zero lower bound, both the output and welfare multipliers are larger and move sign...
