Consumerism arises when patients acquire and use medical information from sources apart from their physicians, such as the Internet and direct-to-patient advertising. Consumerism has been hailed as a means of improving quality. This need not be the result. Consumerist patients place additional...

We examine the investment decision problem of a group whose members have heterogeneous time preferences. In particular, they have different discount factors for utility, possibly not exponential. We characterize the properties of efficient allocations of resources and of shadow prices that would...

Australia pays less than other developed nations for her pharmaceuticals, about 45% as much as the United States. She achieves this result with an ingenious price-contingent subsidy scheme, which turns deadweight loss (due to pricing above marginal cost) into consumer surplus. Pharmaceutical...

Proposition 2.5, a ballot initiative approved by Massachusetts voters in 1980 sharply reduced local property taxes and restricted their future growth. We examine the effects of Proposition 2.5 on municipal finances and assess voter satisfaction with these effects. We find that Proposition 2.5...

One unusual feature of the U.S. property-casualty insurance industry is the coexistence of stock and mutual companies. This paper explores the performance of these forms in the industry through a dynamic assessment of how mutual and stock insurance companies respond to differences in their...

High-quality producers in a vertically differentiated market can reap superior profits by charging higher prices, selling greater quantities, or both. If qualities are known by consumers and production costs are constant, then having a higher quality secures the producer both higher price and...

Climate change is real and dangerous. Exactly how bad it will get, however, is uncertain. Uncertainty is particularly relevant for estimates of one of the key parameters: equilibrium climate sensitivity—how eventual temperatures will react as atmospheric carbon dioxide concentrations double....

Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid - both internally and...

In a world of imperfect information, reputations often guide the sequential decisions to trust and to reward trust. We consider two-player situations where the players meet but once. One player - the truster - decides whether to trust, and the other player - the temptee - has a temptation to...

We study the predictive power of approximately 2.5 million stock picks submitted by individual users to the "CAPS" website run by the Motley Fool company (www.caps.fool.com). These picks prove to be surprisingly informative about future stock prices. Indeed, a strategy of shorting stocks with a...
