role of the behavioral response to taxation and accounts for the incomes of the superrich …

Using a quantitative model that features technical progress in automation and endogenous
skill choice, we show that, given the current US tax system, a sustained fall in automation …

This paper studies the welfare implications of trade opening in a world in which trade raises

This paper provides empirically implementable sufficient statistics formulas for optimal
nonlinear tax systems in the presence of across-income heterogeneity in preferences …
