This paper studies the role of exchange policies as a price discrimination device in a sequential screening model with heterogeneous goods. In the first period, agents are uncertain about their ordinal preferences over a set of horizontally differentiated goods, but have private information...

This paper proposes a mechanism design approach, capable of endogenizing a monopolist's choice between selling and renting in a non-anonymous durable goods setting with short-term commitment. Allowing for mechanisms that determine the good’s allocation not only at the beginning but also at the...

This paper considers a firm whose potential employees have private information on both their productivity and the extent of their fairness concerns. Fairness is modelled as inequity aversion, where fair-minded workers suffer if their colleagues get more income net of production costs. Screening...

We study optimal contracting between a firm selling a divisible good that exhibits positive externality and a group of agents in a social network. The extent of externality that each agent receives from the consumption of neighboring agents is privately held and is unknown to the firm. By...

This paper studies the problem of a monopolistic platform which offers agents connection with one another. Agents have heterogeneous characteristics that are valued by some other agents and observed privately by the principal. The agents are privately informed about their heterogeneous...

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model where a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract's scope. In this model, the buyer balances the need to incentivize...

We present a model of price discrimination where a monopolist faces a consumer who is privately informed about the distribution of his valuation for an indivisible unit of good but has yet to learn privately the actual valuation. The monopolist sequentially screens the consumer with a menu of...

This paper studies the revelation principle for mechanisms with limited commitment when agents have correlated persistent types over the infinite horizon. After characterizing necessary and sufficient conditions to construct a mechanism with same ex-ante payoffs and interim beliefs to all...

Antitrust courts have shortchanged the economic analysis of buyer-side market power in health care. This failure derives to a surprising degree from a single judicial decision, then-Judge Stephen Breyer's 1984 opinion for the First Circuit Court of Appeals in Kartell v. Blue Shield of...
