Much of the air pollution currently regulated under U.S. emissions trading programs is non-uniformly mixed, meaning that health and environmental damages depend on the location and dispersion characteristics of the sources. Existing policy regimes ignore this fact. Emissions are penalized at a...

We determine the change in air pollution damages from U.S. power plant emissions over 2010 to 2017. Annual damages fell from $245 billion to $133 billion over this period, with most of the decline occurring in the East. Decomposition shows that changes in emissions rates reduced damages by $63...

Most environmental policy assumes the form of standards and enforcement. Scarce public budgets motivate the use of disclosure laws. This study explores a new form of pollution disclosure: real-time visual evidence of emissions provided on a free, public website. The paper tests whether the...

This paper constructs new estimates of the air pollution and greenhouse gas costs from long-distance movement of petroleum products by rail and pipelines. While crude oil transportation has generated intense policy debate about rail and pipeline spills and accidents, important externalities -...

"U.S. adoption of a cap-and-trade program for greenhouse gases could place some domestic producers at a disadvantage relative to international competitors who do not face similar regulation. To address this issue, proposed federal climate change legislation includes a provision that would freely...

U.S. adoption of a cap-and-trade program for greenhouse gases could place some domestic producers at a disadvantage relative to international competitors who do not face similar regulation. To address this issue, proposed federal climate change legislation includes a provision that would freely...

For political, jurisdictional and technical reasons, environmental regulation of industrial pollution is often incomplete: regulations apply to only a subset of facilities contributing to a pollution problem. Policymakers are increasingly concerned about the emissions leakage that may occur if...
