We study the Medicare Part D prescription drug insurance program as a bellwether for designs of private, non-mandatory health insurance markets, focusing on the ability of consumers to evaluate and optimize their choices of plans. Our analysis of administrative data on medical claims in Medicare...

The new Medicare Part D program provides prescription drug coverage for older Americans through highly subsidized and tightly regulated plans offered by private insurance firms. For most eligible individuals without coverage from other sources, obtaining Part D coverage would be rational, but it...

We analyze distributional preferences in games in which a decider chooses the provision of a good that benefits a receiver and creates costs for a group of payers. The average decider takes into account the welfare of all parties and has concerns for efficiency. However, she attaches similar...

Physicians' treatment decisions determine the level of health care spending to a large extent. The analysis of physician agency describes how doctors trade off their own and their patients' benefits, with a third party (such as the collective of insured individuals or the taxpayers) bearing the...

We present evidence from a laboratory experiment showing that individuals who believe they were treated unfairly in an interaction with another person are more likely to cheat in a subsequent unrelated game. Specifically, subjects first participated in a dictator game. They then flipped a coin...

In a recurring auction early bids may reveal bidders’ types, which in turn affects bidding in later auctions. Bidders take this into account and may bid in a way that conceals their private information until the last auction is played. The present paper analyzes the equilibrium of a...

The literature on R&D contests implicitly assumes that contestants submit their innovation regardless of its value. This ignores a potential adverse selection problem. The present paper analyzes the procurement of innovations when the procurer cannot commit to never bargain with innovators who...

This paper studies investment incentives in the steady state of a dynamic bilateral matching market. Because of search frictions, both parties in a match are partially locked–in when they bargain over the joint surplus from their sunk investments. The associated holdup problem depends on...

We offer a novel explanation for why some immigrant groups and minorities have persistent, distinctive cultural traits – the presence of a rigid institution. Such an institution is necessary for communities to not fully assimilate to the mainstream society. We distinguish between...

We consider optimal pricing by a profit-maximizing platform running a dynamic search and matching market. Buyers and sellers enter in cohorts over time, meet and bargain under private information. The optimal centralized mechanism, which involves posting a bid-ask spread, can be decentralized...
