| Abstract: | This paper is concerned with the spatial representation of market structure calibrated on actual or intended choice data. Previous models developed for that purpose accomodate consumer heterogeneity by estimating parameters for each consumer, typically using the method of maximum likelihood. This approach to heterogeneity avoids assuming any particular distribution of the individual level parameters across the sample, but leads to problems related to the consistency of the estimates, sufficient degrees of freedom, and the validity of asympotic standard errors and test statistics. |
