Gender-Based Taxation (GBT) satisfies Ramsey's rule of optimality because it taxes at a lower rate the more elastic labor supply of women. This holds when different elasticities between men and women are taken as exogenous. We study GBT in a model in which labor supply elasticities emerge...

This essay discusses the policy debate concerning optimal taxation and the distribution of income. It begins with a brief overview of trends in income inequality, the leading hypothesis to explain these trends, and the distribution of the tax burden. It then considers the normative question of...

We highlight and explain eight lessons from optimal tax theory and compare them to the last few decades of OECD tax policy. As recommended by theory, top marginal income tax rates have declined, marginal income tax schedules have flattened, redistribution has risen with income inequality, and...

Should the income tax include a credit for short taxpayers and a surcharge for tall ones? The standard Utilitarian framework for tax analysis answers this question in the affirmative. Moreover, a plausible parameterization using data on height and wages implies a substantial height tax: a tall...
