This paper examines the implications of uncertainty for the structure of optimal commodity taxes in the presence of a linear income tax. Consumers face uncertain income and commit to consumption of some goods before the resolution of uncertainty and to others after. Preferences are separable...

We characterize optimal taxes on polluting and nonpolluting goods in Ramsey and Mirrlees second-best environments. The polluting good tax differs from the Pigouvian tax by Ramsey terms in the first and by Stiglitz/Mirrlees plus another adjustment term in the second. These terms can be positive,...

What accounts for the existence of positive energy taxes in the US, given that such taxes are regressive and that the income distribution is skewed to the right? The traditional majority-voting equilibrium approach suggests a subsidy; thus we also look at two alternatives. These are the...

This paper presents a political economy model that explains the low rate of emission taxes in the U.S., as well as the fact that neither Democrats nor Republicans propose to increase them. The voters differ according to their wage and capital incomes which are assumed to have a bivariate...

We study optimal income taxation in a framework where one's willingness to report his income truthfully is positively correlated with his type. We show that allowing low-productivity types to cheat leads to Pareto-superior outcomes as compared to deterring them, even if audits can be performed...
