PUBLIC GOOD PROVISION AND THE COMPARATIVE STATICS OF OPTIMAL NONLINEAR INCOME TAXATION

Comparative static properties of the solution to an optimal nonlinear income tax problem are provided for a model in which the government both designs an income tax schedule for redistributive purposes and provides a public good optimally. There are two types of individuals, distinguished by their skill levels, who have the same quasilinear preferences for labor supply and the consumption of a private and a public good. Comparative statics are obtained for the weights in a weighted utilitarian social welfare function, the prices of the two goods, a taste parameter that measures the onerousness of working, and the skill levels.
