A principal provides budgets to agents (e.g., divisions of a firm or the principal's children) whose expenditures provide her benefits, either materially or because of altruism. Only agents know their potential to generate benefits. We prove that if the more "productive" agents are also more...

This paper provides the first rigorous, empirical evidence of the existence of Giffen behavior, i.e., a situation in which consumers respond to an increase in the price of a good by demanding more of it. We begin by examining several theoretical approaches to the Giffen phenomenon and show that...

World food prices have increased dramatically in recent years. We use panel data from 2006 to examine the impact of these increases on the consumption and nutrition of poor households in two Chinese provinces. We find that households in Hunan suffered no nutrition declines. Households in Gansu...

Many developing countries use food price subsidies or price controls to improve the nutrition of the poor. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute towards foods with higher...

We consider the mechanism design problem when agents' types are multidimensional and continuous, and their valuations are interdependent. If there are at least three agents whose types satisfy a weak correlation condition, then for any decision rule there exist balanced transfers that render...

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 use a hazard model to estimate the effect of environmental regulation on the diffusion of membrane cell production technology in the chlorine manufacturing industry. We estimate the effect of regulation on both the adoption of the membrane technology at existing plants and on the exit of...

People are more distrustful of managed care organizations (MCOs) than traditional health plans, a phenomenon that has become known as "managed-care backlash." In a model of the relationship between a patient, insurer, and physician, this paper shows that when the roles of insurer and provider...

A seller faces a buyer with unknown reservation value. We show that buyer risk aversion can make it in the seller's interest to haggle. That is, the seller should make an initial offer and then, if it is rejected, make a second offer with some probability strictly less than one. This is true...
