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)

In the model, firms choose both price and quality including the amount of non-advertising space, the number of reporters, and the number of opinion section staff. I estimate the model using a new data set on newspaper prices and characteristics. I then(More)

It provides a framework to quantify the welfare effect of ownership consolidations taking into account endogenous quality choice. I develop a structural model that captures key features of the U.S. daily newspaper market and propose an(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)
This paper develops a structural model of newspaper markets to analyze the effects of ownership consolidation, taking into account not only firms' price adjustments but also the adjustments in newspaper characteristics. A new data set on newspaper prices and characteristics is used to estimate the model. The paper then simulates the effect of a merger in(More)

Franchisees who own more of a brand's outlets have a greater stake in brand reputation and therefore more incentive to comply with standards than do franchisees with fewer outlets.
