The Price of Gasoline and the Demand for Fuel Economy: Evidence from Monthly New Vehicles Sales Data
This paper uses a unique data set of monthly new vehicle sales by detailed model from 1978 to 2007 and implements a new identification strategy to estimate the effect of the price of gasoline on consumer demand for fuel economy. The authors control for unobserved vehicle and consumer characteristics by using within model-year changes in the price of gasoline and vehicle sales. They find a significant demand response, as nearly half of the decline in market share of U.S. manufacturers from 2002-2007 was due to the increase in the price of gasoline. On the other hand, an increase in the gasoline tax would only modestly affect average fuel economy.
