This paper uses the notion of augmented utility to summarize models of utility maximization (MUM). The models covered include non-separable utility maximization and common behavioral models of discounting. Moreover, the paper provides as novel special cases necessary and sufficient conditions...

This note provides a nonparametric test for dynamic discrete random utility models (DDRUM). The methodology can be used to understand the welfare implications of price changes in demand data when there is no uncertainty for consumers that have preferences over product characteristics or discrete...
