Abstract: Recent legislation has increased the Corporate Average Fuel Economy (CAF) standard by 40 percent, which represents the first major increase in the standard since its creation in 1975. Previous analysis of the CAF standard has focused on the short run effects, in which vehicle characteristics are held fixed, or the long run, when firms can adopt new powertrain technology. This paper focuses on the medium run, when firms can choose characteristics such as weight and power, and have a limited ability to adopt engine technology. We first document the historical importance of the medium run and then estimate consumers? willingness-to-pay for fuel efficiency, power and weight. We employ a unique empirical strategy that accounts for the characteristics? endogeneity, which has not been addressed in the literature, by using variation in the set of engine models used in vehicle models. The results imply that an increase in power has an equal effect on vehicle sales as a proportional increase in fuel efficiency. We then simulate the medium run effects of an increase in the CAF standard. The policy reduces producer and consumer welfare and causes substantial transfers across firms, but the effects are significantly smaller than in previous studies.
