We study the impact of expert reviews on the demand for HIV treatments. A novel feature of our study is that we observe two reviews for each HIV drug and focus attention on consumer responses when experts disagree. Reviews are provided by both a doctor and an activist in the HIV lifestyle...

We estimate whether consumers respond to local energy costs when purchasing appliances. Using a dataset from an appliance retailer, we compare demand responsiveness to a measure of energy costs that varies with local energy prices versus purchase prices. We strongly reject that consumers are...

We study a consumer non-sequential search oligopoly model with search cost heterogeneity. We first prove that an equilibrium in mixed strategies always exists. We then examine the nonparametric identification and estimation of the costs of search. We find that the sequence of points on the...

We conduct an empirical case study of the U.S. beer industry to analyze the disruptive effects of locally-manufactured, craft brands on market structure, an increasingly common phenomenon in CPG industries typically attributed to the emerging generation of adult Millennial consumers. We document...
