This paper develops a mechanism design approach to study externalities and re-distribution. The mechanism screens individuals’ social weights to strike a balance among broad distributional objectives, incentives to work, and incentives to reduce externalities. The welfare-optimal allocation...

The paper presents an axiomatic restatement of the standard approach to nonlinear income taxation. It assumes a finite number of taxpayers rather than an uncountable infinity. Analytical tools are developed which facilitate proving the existence of tax schedules that are continuous,...

Several frictions restrict the government s ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too...

The paper studies the design of couples income taxation when consumption and labor supply decisions within the couple are made in a cooperative way according to some bargaining scheme. Specifically, the couple maximizes a weighted sum of the spouses utilities. In the first part of the paper, the...

Previous studies have shown that the optimal marginal tax rate at the bottom of the income distribution may be positive, negative, or even zero. This paper reexamines this problem in a unified framework and tries to evaluate the arguments. It turns out that the case for positive marginal tax...
