An Empirical Model of Automobile Engine Variant Pricing

Abstract

This paper estimates a random-coefficients structural model of the demand for car model engine variants. It uses a new identification approach that assumes the mean unobserved quality is the same for all engine variants within a model. The demand estimates imply that absolute markups increase in horsepower within a car model, while percentage markups are constant or falling in horsepower. The estimated results–as well as simulations of a simple theory model–show that prices are not typically cost-plus-fixed-fee, and absolute markups may increase in quality.
