Policy function iteration methods for solving and analyzing dynamic stochastic general equilibrium models are powerful from a theoretical and computational perspective. Despite obvious theoretical appeal, significant startup costs and a reliance on grid-based methods have limited the use of...

Recent proposals to reduce U.S. debt reveal large differences in their implied targets. These differences demonstrate the uncertainty surrounding future tax rates and long-run debt targets. We use a standard real business cycle model in which a Bayesian household learns about the state-dependent...

When monetary policy faces a zero lower bound (ZLB) constraint on the nominal interest rate, determinacy is not guaranteed even if the Taylor principle is satisfied when the ZLB does not bind. This paper shows the boundary of the determinacy region imposes a clear tradeoff between the expected...

This article presents global solutions to standard New Keynesian models with a zero lower bound (ZLB) constraint on the nominal interest rate. Rather than focus on specific sequences of shocks, we provide the solution for all combinations of technology and discount factor shocks and a thorough...

When monetary policy faces a zero lower bound (ZLB) constraint on the nominal interest rate, a minimum state variable (MSV) solution may not exist even if the Taylor principle holds when the ZLB does not bind. This paper shows there is a clear tradeoff between the expected frequency and average...

Policy function iteration methods for solving and analyzing dynamic stochastic general equilibrium models are powerful from a theoretical and computational perspective. Despite obvious theoretical appeal, significant startup costs and a reliance on grid-based methods have limited the use of...

Legislative and implementation lags imply that substantial time evolves between when news arrives about fiscal changes and when the changes actually take place—time when households and firms can adjust their behavior. We identify two types of fiscal news—government spending using the Survey...

Changes in fiscal policy typically entail two kinds of lags: the legislative lag--between when legislation is proposed and when it is signed into law--and the implementation lag--from when a new fiscal law is enacted and when it takes effect. These lags imply that substantial time evolves...

This paper develops a dynamic asset pricing model with persistent heterogeneous beliefs. The model features competitive traders who receive idiosyncratic signals about an underlying fundamentals process. We adapt Futia’s (1981) frequency domain methods to derive conditions on the fundamentals...
