This paper discusses the nature, and magnitude, of externalities associated with automobile use, including local and global pollution, oil dependence, traffic congestion and traffic accidents. It then discusses current federal policies affecting these externalities, including fuel taxes,...

Energy models suggest that the cost of reducing carbon emissions from the transportation sector is high relative to other sectors, such as electricity generation. However, this paper shows that taxes to reduce passenger vehicle emissions produce large net benefits, rather than costs, when...

This paper provides a first attempt to estimate the cross-price elasticity between alcoholic beverages and leisure, which is critical for assessing how much alcohol taxation might be warranted on fiscal grounds. We estimate an Almost Ideal Demand System defined over alcohol, leisure, and other...

This paper reviews literature on the optimal design of pricing policies to reduce urban automobile congestion. The implications of a range of complicating factors are considered, such as traffic bottlenecks, constraints on which roads and freeway lanes in the road network can be priced, driver...

This paper uses an analytical-simulation model to examine the optimal extent and welfare effects of pricing reforms for passenger transportation in Mexico City. The model incorporates travel by auto, microbus, public bus, and rail, plus externalities from local and global air pollution, traffic...

We examine the extent to which various environmental policy instruments meet major evaluation criteria, including cost-effectiveness, distributional equity, minimization of risk in the presence of uncertainty, and political feasibility. Instruments considered include emissions taxes, tradable...

We use analytical and numerical models to explain and quantify the welfare effects of subsidies for artemisinin combination treatments (ACTs), a valuable new class of antimalarial drugs. There are two (second-best) efficiency rationales for such subsidies: by expanding drug use, they reduce...

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

This paper provides an exhaustive review of critical issues in the design of climate mitigation policy by pulling together key findings and controversies from diverse literatures on mitigation costs, damage valuation, policy instrument choice, technological innovation, and international climate...
