Adjusting the Value of a Statistical Life for Age and Cohort Effects.
Review of Economics and Statistics ,
90 (3), 573-581.
AbstractTo resolve the theoretical ambiguity in the effect of age on the value of statistical life (VSL), this article uses a novel, age-dependent fatal risk measure to estimate age-specific hedonic wage regressions. VSL exhibits an inverted-U-shaped relationship with age. In the year 2000 cross section, workers’ VSL rises from $3.7 million (ages 18–24) to $9.7 million (35–44), and declines to $3.4 million (55–62). Controlling for birth-year cohort effects in a minimum distance estimator yields a peak VSL of $7.8 million at age 46, and flattens the age-VSL relationship. The value of statistical life-year also follows an inverted-U shape with age.

Issues in Designing U.S. Climate Change Policy.
The Energy Journal ,
30 (3), 179-210.
AbstractOver the coming decades, the cost of U.S. climate change policy likely will be comparable to the total cost of all existing environmental regulation—perhaps 1–2 percent of national income. In order to avoid higher costs, policy efforts should create incentives for firms and individuals to pursue the cheapest climate change mitigation options over time, among all sectors, across national borders, and in the face of significant uncertainty. Well-designed national greenhouse gas mitigation policies can serve as the foundation for global efforts and as an example for emerging and developing countries. We present six key policy design issues that will determine the costs, cost-effectiveness, and distributional impacts of domestic climate policy: program scope, cost containment, offsets, revenues and allowance allocation, competitiveness, and R&D policy. We synthesize the literature on these design features, review the implications for the ongoing policy debate, and identify outstanding research questions that can inform policy development.

A Tax-Based Approach to Slowing Global Climate Change.
National Tax Journal ,
61, 493-517.
AbstractIn this paper, we discuss the design of carbon dioxide (CO2) taxes at the domestic and international level and the choice of taxes versus a cap-and-trade system. A strong case can be made for taxes on uncertainty, fiscal, and distributional grounds, though this critically hinges on policy specifics and how revenues are used. The efficient near-term tax is at least $5–$20 per ton of CO2 and the tax should be imposed upstream with incentives for downstream sequestration and abatement of other greenhouse gases. At the international level, a key challenge is the possibility that emissions taxes might be undermined through offsetting changes in other energy policies.
