This paper develops a model of health insurance that incorporates behavioral biases. In the traditional model, people who are insured overuse low value medical care because of moral hazard. There is ample evidence, though, of a different inefficiency: people underuse high value medical care...

We investigate whether information technology can help physicians more efficiently acquire new knowledge in a clinical environment characterized by information overload. Our analysis makes use of data from a randomized trial as well as a theoretical model of the influence that information...

A well-recognized problem in the multitasking literature is that workers might substantially reduce their effort on tasks that produce unobservable outputs as they seek the salient rewards to observable outputs. Since the theory related to multitasking is decades ahead of the empirical evidence,...

We survey theoretical developments in the literature on the limits of arbitrage. This literature investigates how costs faced by arbitrageurs can prevent them from eliminating mispricings and providing liquidity to other investors. Research in this area is currently evolving into a broader...

In cross-sectional data sets from ten credit markets, we find that middle-aged adults borrow at lower interest rates and pay fewer fees relative to younger and older adults. Fee and interest payments are minimized around age 53. The measured effects are not explained by observed risk...

Asset-backed securities represent one of the largest and fastest growing financial markets. Under securitization, agents perform functions (for fees) that would alternatively be performed by a vertically integrated lender with ownership of a whole loan. We examine how outsourcing impacts...

Some research has suggested that companies with defined benefit (DB) pensions are sometimes significantly misvalued by the market. This is because the measures of pension cost and pension net liabilities embedded in financial statements, taken at face value, can provide very misleading picture...

We examine misconduct in credence good markets with price taking experts. We propose a market-level model in which price-taking experts extract surplus based on the value of their firm's brand and their own skill. We test the predictions of the model using sales complaint data for exclusive and...

This paper examines why credit constraints for domestic and exporting firms arise in a setting where banks do not observe firms' productivities. To maintain incentive-compatibility, banks lend below the amount needed for first-best production. The longer time needed for export shipments induces...

We establish an important role for the firm by studying capital reallocation decisions of mutual fund firms. At least 30% of the value mutual fund managers add can be attributed to the firm's role in efficiently allocating capital amongst its mutual fund managers. We find no evidence of a...
