Abstract

In this paper we show that the problem of demand inversion in multinomial
choice models is equivalent to the determination of stable outcomes in
matching models. This result is very general and applies to random utility
models that are not necessarily additive or smooth. Based on this
equivalence, we argue that the algorithms for the determination of stable
matchings can provide effective computational methods to inverse multinomial
choice models, and we give a numerical benchmark of these algorithms. Our
approach allows to estimate models that were previously difficult to
estimate, such as the pure characteristics model, as well as nonadditive
random utility models. The equivalence also allows to exploit the theory of
stable matchings in order to describe important properties of the set of
utilities solution to the demand inversion problem, and to study the cases
of existence and uniqueness of identified utilities, as well as obtain
consistency results.
