Using analytical and numerical general equilibrium models, we show that preexisting factor taxes produce a "tax-interaction effect" that increases the costs of pollution taxes and quotas. Under policies that raise revenue and recycle it through cuts in marginal factor tax rates, this effect is...

We show that under typical conditions the simple "excess-burden triangle" formula substantially underestimates the excess burden of commodity taxes, in some cases by a factor of 10 or more. This formula performs poorly because it ignores general equilibrium interactionsmost important,...

This paper develops and implements an analytical framework for estimating optimal taxes on the fuel use and mileage of heavy-duty trucks in the United States, accounting for external costs from congestion, accidents, pavement damage, noise, energy security, and local and global pollution. The...
