Section 321 of the 1930 Tariff Act allows up to $800 in imports per person per day to enter the US duty-free and with minimal customs requirements. Fueled by rising direct-to-consumer trade, these "de minimis" shipments have exploded yet are not recorded in Census trade data. Who benefits from...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

Half of the jobs in the U.S. feature pay-for-performance. We derive novel incidence and optimum formulas for the overall rate of tax progressivity and the top tax rates on total earnings and bonuses, when such labor contracts arise from moral hazard frictions within firms. Optimal taxes account...

How much information should governments reveal to consumers if consumption choices have uninternalized consequences to society? How does an alternative tax policy compare to information disclosure? We develop a price theoretic model of information design that allows empiricists to identify the...

Half of the jobs in the U.S. feature pay-for-performance. We study nonlinear income taxation in a model where such contracts arise in private labor markets that are constrained by moral hazard frictions. We derive novel formulas for the incidence of arbitrarily nonlinear reforms of a given tax...
