A number of recent studies have shown that the general equilibrium welfare effects of externality-correcting policies depend importantly on pre-existing taxes in the economy, particularly those that distort the labor market. This paper extends the prior literature by allowing for consumption...

This paper first describes the new literature in environmental economics on the socalled "double dividend" and then explores its implications for a broad range of economic issues. The basic finding in this literature is that in a second-best, general equilibrium setting, environmental measures...

This paper explores the interactions between taxes on work-related traffic congestion and pre-existing distortionary taxes in the labor market. A congestion tax raises the overall costs of commuting to work and discourages labor force participation at the margin, when revenues are returned in...

Gasoline taxes are widely perceived as the most efficient instrument for reducing gasoline consumption because they exploit all behavioral responses for reducing fuel use, including reduced driving and improved fuel economy. At present, however, higher fuel taxes are viewed as a political...

Health policy will be a major issue in Britain's next general election. The Labour government is committed to a substantial increase in funds for the National Health Service (NHS) and has eliminated tax relief for private health insurance. The Conservative Opposition party favors subsidizing...

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 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...

This paper develops and implements an analytical framework for estimating the optimal levels and welfare effects of alcohol taxes and drunk-driver penalties, accounting for externalities and how policies interact with the broader fiscal system. We find that the fiscal component of the optimal...

This paper derives intuitive and empirically useful formulas for the optimal pricing of passenger transit and for the welfare effects of adjusting current fare subsidies, for peak and off-peak urban rail and bus systems. The formulas are implemented based on a detailed estimation of parameter...
