This paper investigates consumer switching costs in the context of health insurance markets, where adverse selection is a potential concern. Switching costs contribute to poor choices when the market environment changes and consumers do not adjust appropriately. Though previous work has studied the problems of adverse selection and consumer choice(More)
Game-theoretic models are frequently employed to study strategic interaction between agents. Empirical research has focused on estimating payoff functions while maintaining strong assumptions regarding the information structure of the game. I show how to relax informational assumptions to enhance the credibility of empirical analysis in discrete games. I(More)
We show that social interaction reduces the diversity of products purchased by consumers in two retail settings. First, we consider a field experiment conducted by Sweden’s monopoly alcohol retailer and find that moving purchases from behind the counter to self-service disproportionately increases the sales of difficult-to-pronounce products. Second, we use(More)
We show that healthcare providers face a tradeoff between increasing the number of patients they treat and improving their quality of care. To measure the magnitude of this quality-quantity tradeoff, we estimate a model of dialysis provision that explicitly incorporates a center’s unobservable and endogenous choice of treatment quality while allowing for(More)
This study addresses the need to account for unobserved heterogeneity in auctions in order to improve our estimates of the distribution of bidder values. Though the empirical auction literature is vast, few studies allow for there to be differences in the objects being auctioned which are unobservable to the researcher. The method presented in this paper(More)
This paper considers a simple model of a firm’s name choice. A main prediction of the model, that the content of a firm’s name will be correlated with its service quality under certain conditions, belies the intuition that a firm’s freely chosen name will represent only “cheap talk” about itself. Using unique data from markets for residential plumbing(More)
This paper considers the relationship between market structure and health outcomes in a setting with stark preferences: urology patients disproportionately match with a urologist of the same gender. In the United States, however, fewer than 6% of urologists are women despite women constituting 30% of patients. We explain a portion of this disparity with a(More)
An important type of product differentiation in the venture capital (VC) market is industry specialization. We estimate a market structure model to assess competition among VCs—some of which specialize in a particular industry and others of which are generalists—and find that the incremental effect of additional same-type competitors increases as the number(More)
Medicare’s prospective payment system for long-term acute-care hospitals (LTCHs) provides modest reimbursements at the beginning of a patient’s stay before jumping discontinuously to a large lump-sum payment after a pre-specified number of days. We show that LTCHs respond to financial incentives by disproportionately discharging patients after they cross(More)
This paper studies entry and capacity decisions by dialysis providers in the United States. We estimate a structural model where providers make continuous strategic choices of capacity based on their private information about own costs and knowledge of the distribution of competitors’ private information. We evaluate the impact on the market structure and(More)
