Busse, Meghan, Knittel, Christopher and Zettelmeyer, Florian “Are Consumers Myopic? Evidence from New and Used Car Purchases” (December 2009) (Revised version published in The American Economic Review, 103(1), February 2013) | WP-201
We investigate whether car buyers are myopic about future fuel costs. We estimate the effect of gasoline prices on short-run equilibrium prices of cars of different fuel economies. We then compare the implied changes in willingness-to-pay to the associated changes in expected future gasoline costs for cars of different fuel economies in order to calculate implicit discount rates. Using different assumptions about annual mileage, survival rates, and demand elasticities, we calculate a range of implicit discount rates similar to the range of interest rates paid by car buyers who borrow. We interpret this as showing little evidence of consumer myopia.
