We compile data spanning the period 1900 2014 and up to 30 countries to study long-run patterns in the tax elasticity of top incomes. Our results show that top tax elasticities vary tremendously over time; they were medium-to-low before 1950, virtually zero during the postwar era up to 1980 and...

We evaluate reforms to the U.S. tax system in a dynamic setup with heterogeneous married and single households, and with an operative extensive margin in labor supply. We restrict our model with observations on gender and skill premia, labor force participation of married females across skill...

Discrete-choice models of labor supply have become very popular for ex ante evaluations of policy reforms as they easily account for non-convex budget sets. We test the constraints imposed in practice on these models and suggest a fully flexible model that significantly improves fit.
