Disaggregate demand in the marketplace exists on a grid determined by the package sizes offered by manufacturers and retailers. While consumers may want to purchase a continuous-valued amount of a product, realized purchases are constrained by available packages. This constraint might not be...

Many economic models of consumer demand require researchers to partition sets of products or attributes prior to the analysis. These models are common in applied problems when the product space is large or spans multiple categories. While the partition is traditionally fixed a priori, we let the...

Platform goods are commonly seen in practice. They occur when a company offers a durable product (platform) and a consumable product (component). Platform goods are desirable because they create local monopolies and increase the switching cost of products. Platform goods have been extensively...

Utility maximization is implicit in models of consumer choice, learning, forward-looking behavior and substitution. It is a central feature of models of market competition built on the aggregation of individual choices, and is assumed in nearly all quantitative models of behavior. Yet, while the...

We measure the causal effects of income and wealth on the demand for private-label products. Prior research suggests that these effects are large and, in particular, that private-label demand rises during recessions. Our empirical analysis is based on a comprehensive household-level transactions...
