The Latest Natural Experiment: Carmageddon

I predict: two years from now someone will present a paper in the EE session of the NBER summer institute that exploits Carmageddon as a natural experiment to estimate various acute effects of air pollution or some other consequence of reduced driving and congestion.  Maybe someone will try to extrapolate their findings to estimate the social costs and benefits of roads.

I have far less confidence that I will receive an invitation to said meetings.  Aw well...


  1. Yup, we're working on it, at least from the air quality and emissions point of view. Perhaps you'd like to put a cost and benefit on it?
