This paper studies empirically the effects of and the interactions amongst economic and political liberalizations. Economic liberalizations are measured by a widely used indicator that captures the scope of the market in the economy, and in particular of policies towards freer international...

Many governments have engaged in policy experimentation in various forms to resolve uncertainty and facilitate learning. However, little is understood about the characteristics of policy experimentation, and how the structure of experimentation may affect policy learning and policy outcomes. We...

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...

According to CPS data, men 65 to 69 were about six percentage points less likely to be retired in 2004 than in 1992. CPS and Health and Retirement Study (HRS) data indicate a corresponding difference of 3 percentage points between 1998 and 2004. Simulations with a structural retirement model...

The focus of policy reform in developing countries has moved from getting prices right to getting institutions right, and accordingly countries are increasingly being advised to move towards "best-practice" institutions. This paper argues that appropriate institutions for developing countries...

Despite the social importance of desegregation and the magnitude of the literature, we have lacked a comprehensive accounting of the basic facts of school desegregation....

We estimate the effect of political regime transitions on growth with semi-parametric methods, combining difference in differences with matching, that have not been used in macroeconomic settings. Our semi-parametric estimates suggest that previous parametric estimates may have seriously...
