This paper investigates the role of the outside good utility function on admissible substitution patterns in direct utility models of discrete/continuous demand. We first present a set of novel results that characterize the functional form of price effects within this class of models. The...

A direct utility approach can handle multiple discrete/continuous choice outcomes. However, there is a trade-off between allowing correlations between unobserved perceived qualities of two alternatives and computational burden. If we allow the correlations, then we have to do numerical...
