This chapter studies the microeconometric treatment-effect and structural approaches to dynamic policy evaluation. First, we discuss a reduced-form approach based on a sequential randomization or dynamic matching assumption that is popular in biostatistics. We then discuss two complementary...

This paper develops methods for evaluating marginal policy changes. We characterize how the effects of marginal policy changes depend on the direction of the policy change, and show that marginal policy effects are fundamentally easier to identify and to estimate than conventional treatment...

In this lecture, I argue that there are remarkable parallels between how monetary and fiscal policies operate on the macro economy and that these parallels are sufficient to lead us to think about transforming fiscal policy and fiscal institutions as many countries have transformed monetary...

Dramatic fiscal developments in the wake of the 2008 financial crisis and global recession led researchers to recognize how little we know about fiscal policies and their impacts. This essay argues that fiscal analysis that aims to address pertinent issues and provide useful inputs to...

Increases in government spending trigger substitution effects — both inter- and intra-temporal — and a wealth effect. The ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior. Studies that impose active monetary policy and passive fiscal policy...

This paper makes changes in monetary policy rules (or regimes) endogenous. Changes are triggered when certain endogenous variables cross specified thresholds. Rational expectations equilibria are examined in three models of threshold switching to illustrate that (i) expectations formation...
