Spreading the Wealth Around: Reflections Inspired by Joe the Plumber. Eastern Economic Journal. 2010;36 :285-298.
AbstractThis 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 how the tax system should be designed. The conventional utilitarian framework is found to be wanting, as it leads to prescriptions that conflict with many individuals’ moral intuitions. The essay then explores an alternative normative framework, dubbed the Just Deserts Theory, according to which an individual’s compensation should reflect his or her social contribution.

The Optimal Taxation of Height: A Case Study in Utilitarian Income Redistribution. American Economic Journal: Economic Policy. 2010;2 (1) :155-176.
AbstractShould the income tax system include a tax credit for short taxpayers and a tax surcharge for tall ones? This paper shows that the standard Utilitarian framework for tax policy analysis answers this question in the a¢ rmative. Moreover, based on the empirical distribution of height and wages, the optimal height tax is substantial: a tall person earning $50,000 should pay about $4,500 more in taxes than a short person earning the same income. This result has two possible interpretations. One interpretation is that individual attributes correlated with wages, such as height, should be considered more widely for determining tax liabilities. Alternatively, if policies such as a tax on height are rejected, then the standard Utilitarian framework must in some way fail to capture our intuitive notions of distributive justice.
