I develop and estimate a model of the U.S. automobile industry in which firms choose the fuel efficiency of their new vehicles. I then use the model to analyze the 2008 gas price increase of 28%. Firms face a technological frontier between providing fuel efficiency and other quality, and the gas price shifts incentives to locate along this frontier. Where(More)

I estimate the model using a new data set on newspaper prices and characteristics. I then(More)

I develop and estimate a model of the U.S. automobile industry in which firms choose the fuel efficiency of their new vehicles. I use the model to analyze the 2008 gas price increase, and to computer the " gas-tax equivalent " of the 35 miles-per-gallon (mpg) CAFE proposals. Firms face a technological frontier between providing fuel efficiency and other(More)

Both parents and children provided information on children's adjustment. In predicting children's reports of their adjustment, the(More)
