  • 演講摘要 : This talk is concerned with random utility models for discrete and continuous choice data. Such econometric models allow for unobserved preference heterogneity. Their estimation is of interest when the distribution of consumer valuations is relevant in practice. Situations in which consumers seek a service delivered under a capacity constraint - such as, e.g., Internet access at pre-specified speed - are a prime example. The talk elaborates on how to econometrically specify such models and under which conditions they are identifiable from demand data. This class of models is illustrated in an application to data from the U.C. Berkeley Internet Demand Experiment (INDEX).
