Abstract
Many economic models of consumer demand require researchers to partition sets of products or attributes prior to the analysis. These models are common in empirical settings in which the product space is large or spans multiple categories. While partitioning demand can offer both statistical and behavioral advantages, doing so can also impose significant restrictions on the set of admissible substitution patterns. In this dissertation, we let the partition be a model parameter and propose a Bayesian method for inference. The challenge in modeling partitions is that they are defined on a high-dimensional, discrete, and non-Euclidean domain. We build on previous nonparametric Bayesian models for random partitions to construct a new partition distribution characterized by a location partition and scale parameter. This location-scale partition distribution is useful in two ways: (1) as a proposal distribution within the context of a Markov chain Monte Carlo routine; and (2) as a prior or random-effects distribution of partition heterogeneity. Our method is illustrated in the context of both store-level and household-level demand models. We find that allowing for uncertainty in the partition is important for preserving model flexibility, improving demand forecasts, learning about the structure of demand, and informing targeted marketing strategies.
