We study the interplay between autonomous transportation, carpooling, and road pricing. We discuss how improvements in these technologies, and interactions among them, will affect transportation markets. Our main results show how to achieve socially efficient outcomes in such markets, taking...

We investigate the "generalized second price" auction (GSP), a new mechanism which is used by search engines to sell online advertising that most Internet users encounter daily. GSP is tailored to its unique environment, and neither the mechanism nor the environment have previously been studied...

We analyze some of the perverse incentives that may arise under the current Medicare prescription drug benefit design. In particular, risk adjustment for a stand-alone prescription drug benefit creates perverse incentives for prescription drug plans' coverage decisions and/or pharmaceutical...

In this paper we study "investment tournaments," a class of decision problems that involve gradual allocation of investment among several alternatives whose values are subject to exogenous shocks. The decision-maker's payoff is determined by the final values of the alternatives. An important...

We introduce the interview assignment problem, which generalizes the one-to-one matching model of Gale and Shapley (1962) by introducing a stage of costly information acquisition. Firms learn preferences over workers via costly interviews. Even if all firms and workers conduct the same number of...

Consider an environment where long-lived experts repeatedly interact with short-lived customers. In periods when an expert is hired, she chooses between providing a profitable major treatment or a less profitable minor treatment. The expert has private information about which treatment best...

This paper applies ideas from mechanism design to model procurement of prescription drugs. We present a mechanism for government-funded market-driven drug procurement that achieves very close to full static efficiency -- all members have access to all but at most a single drug -- without...

This paper explores information disclosure in matching markets, e.g., the informativeness of transcripts given out by universities. We show that the same, quot;benchmark,quot; amount of information is disclosed in essentially all equilibria. We then demonstrate that if universities disclose the...
