Unlike the Proportional Hazard Model (PHM), first proposed by Cox (1972), the ARM incorporates the effects of covariates on the individual hazard function in an (as opposed to ) manner. While a...

We propose a utility-theoretic brand-choice model that accounts for four different sources of state dependence: 1. effects of lagged choices (), 2. effects of serially correlated error terms in the random utility function (), 3. effects of serial correlations between utility-maximizing...

This paper advances the literature on multicategory demand models by simultaneously handling of the household. We propose a model of and outcomes in multiple categories. Our results show that cross-category promotional spillovers are asymmetric between the two product categories of bacon and...
