The Efect of Differences in Buyer and Non-Buyer Characteristics on Equilibrium Price-Elasticities: an Empirical Study on the Italian Automobile Market

  • Franco Mariuzzo

    (Department of Economics, Trinity College)

This paper provides an empirical analysis of own- and cross-price elasticities of substitution for the 1989-2000 Italian automobile industry. We use product-level data consistent with a structural model of equilibrium in a differentiated products oligopolistic industry and follow a random coefficient model to get reliable price elasticities of substitution. We enrich our data with a special section having information on individuals buying and non-buying vehicles. Tracking the di?erent characteristics of individuals buying and non-buying ends to be determinant for more precise estimations. Our data show that models that disregard this refined information tend to consistently overestimate price elasticities.
