This paper evaluates the extent to which a DSGE model can account for the impact of tax policy shocks. We estimate the response of macroeconomic aggregates to anticipated and unanticipated tax shocks in the U.S. and find that unanticipated tax cuts have persistent expansionary effects on output,...

This paper considers a matching model in which multiple steady-state unemployment rates exist if government expenditures and unemployment benefits are high enough. The focus on the extensive margin and a possible transition to a steady state with higher unemployment rates imply that the effect...

This paper characterizes the time-consistency properties of the set of Pareto efficient (or second best) fiscal policies, in a two-class, stochastic economy similar to that in Judd (1985). The key finding is that the continuation of any Pareto efficient policy is always Pareto efficient. Hence,...

When young individuals face binding debt constraints, their human capital investments will be insufficiently financed by private creditors. If generations overlap, then a well-designed fiscal policy may be able to improve human capital investments by replacing missing capital markets with an...

In DSGE models, fiscal policy is typically described by simple rules in which tax rates respond to the level of output. We show that there is only weak empirical evidence in favor of such specifications in U.S. data. Instead, the cyclical movements of labor and capital income tax rates are...

We show that credit market imperfections substantially increase the government-spending multiplier when the economy enters a liquidity trap. This finding is explained by the tight association between capital goods and firms' collateral, a relationship that we highlight as the...
