What is a feasible and efficient policy to regulate air pollution from vehicles? A Pigouvian tax is technologically infeasible. Most countries instead rely on exhaust standards that limit air pollution emissions per mile for new vehicles. We assess the effectiveness and efficiency of these...

Taking advantage of the structure of the 1990 Clean Air Act Amendments (CAAA), we study the tradeoff between efficiency and equity associated with different levels of discretionary power when delegating regulatory authority to lower levels of government. Exploiting an instrumental variables...

Ideally, carbon offset programs issue each project a number of offset credits equal to the number of reductions in carbon emissions it achieves. Realistically, any one project likely receives more or less offset credits than the emissions it reduces. Therefore, the net emissions impact of offset...
