A platform matches agents from two sides of a market to create a trading opportunity between them. The agents subscribe to the platform by paying subscription fees which are contingent on their reported private types, and then engage in strategic interactions with their matched partner(s). A...

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...

Two firms engage in price competition to attract buyers located on a network. The value of the good of either firm to any buyer depends on the number of neighbors on the network who adopt the same good. When the size of externalities increases linearly with the number of adoptions, we identify...

This paper studies collusion in repeated auctions when bidders communicate prior to each stage auction. The paper presents a folk theorem for independent and correlated private signals and general interdependent values. Specifically, it identifies conditions under which an equilibrium collusion...

A principal acquires information about a shock and then discloses it to an agent. After the disclosure, the principal and agent each decide whether to take costly preparatory actions that yield benefits only when the shock strikes. The principal maximizes his expected payoff by controlling the...

Two sellers engage in price competition to attract buyers located on a network. The value of the good of either seller to any buyer depends on the number of neighbors on the network who consume the same good. For a generic specification of consumption externalities, we show that an equilibrium...

This paper studies dynamic price competition over two periods between two firms selling differentiated durable goods to two buyers who are privately informed about their types, but have valuations of the two goods dependent on the other buyer's type. The firms' pricing strategy in period 1 must...

This paper studies the problem of information revelation in a multi-stage tournament where the agents’ effort in each stage gives rise to a stochastic performance signal privately observed by the principal. The principal controls the agents’ effort incentive through the use of a feedback...

This paper studies a monopoly pricing problem when the seller can also choose the timing of a trade with each buyer endowed with private information about the seller’s good. A buyer’s valuation of the good is the weighted sum of his and other buyers’ private signals, and is affected by the...
