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...

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...

We consider mechanism design in social choice problems in which agents’ types are continuous, multidimensional, and mutually payoff-relevant, and there are three or more agents. If the center receives a signal that is stochastically related to the agents’ types and direct returns are...

Recommender and reputation systems seek to inform potential customers by securing current consumers' feedback about products and sellers. This paper proposes a payment-based system to induce honest reporting of feedback. The system applies proper scoring rules to each buyer's report, looking to...

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...

Many recommendation and decision processes depend on eliciting evaluations of opportunities, products, and vendors. A scoring system is devised that induces honest reporting of feedback. Each rater merely reports a signal, and the system applies proper scoring rules to the implied posterior...

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...

We study the quality choices of institutional health-care providers, such as hospitals, assuming that the utility function of the key organizational decision-maker includes both quality of care and financial surplus. An increase in the decision-maker’s rate of surplus retention leads to a...

We study the quality choices of institutional health-care providers, such as hospitals, assuming that the utility function of the key organizational decision maker includes both quality of care and financial surplus. We are primarily concerned with how changes in outside claims—particularly...
