摘要

Using data from a 1989 household survey of new vehicle buyers, this paper develops and estimates a nested logit model of new vehicle demands. In comparison with the more restrictive multinomial logit model, which assumes that the error terms are uncorrelated, the results support a nested structure of vehicle choice in which the error terms for purchases within the same fuel efficiency category are correlated. Among the findings, improvements in vehicle size, safety and quality increase a make/model's demand.
