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...

Emissions testing in the laboratory forms an essential part of the European type approval procedure for light-duty vehicles. The approach yields reproducible and comparable emissions data and provides clear design criteria for vehicles that have to comply with applicable emission limits....

Using 3 years of data from the 47 prefectures of Japan, we estimate the behavior of households that simultaneously make discrete decisions about vehicle ownership and continuous decisions about driving distance. We use the estimated parameters to calculate elasticities and to simulate the...
