We examine the impacts of increased US gasoline taxes in a model that links the markets for new, used, and scrapped vehicles and recognizes the considerable heterogeneity among households and cars. Household choice parameters derive from an estimation procedure that integrates individual choices...

Fuel economy standards change the composition of the vehicle fleet, potentially influencing accident fatality risks. I estimate the direction and magnitude of this impact, introducing a correction for selection on driver behavior. A policy application using my new estimates shows that the...

We estimate the sensitivity of scrap decisions to changes in used car values and show how this "scrap elasticity" produces emissions leakage under fuel efficiency standards, a process known as the Gruenspecht effect. We first estimate the effect of gasoline prices on used vehicle values and...

With a focus on two sorts of regulation--renewable electricity and clean energy standards, and automobile fuel-economy standards--we analyze problematic interactions that arise when state policies are nested within the domain of Federal policy. Here state efforts may fail to reduce greenhouse...
