We study a principal-agent model. The parties are symmetrically informed at first; the principal then designs the screening mechanism and, concurrently, the process by which the agent learns his type. Because the agent can opt out of the mechanism ex post, it must leave him with nonnegative...

We study ex post information rents in sequential screening models where the agent receives private ex ante and ex post information. The principal has to pay ex post information rents for preventing the agent to coordinate lies about his ex ante and ex post information. When the agent's ex ante...

When a monopolist has discretion over the timing of infrastructure investments, regulation of post-investment prices interferes with incentivizing socially optimal investment timing. In a model of regulated lumpy investment under uncertainty, we study regulation when the regulator can condition...

This paper characterizes the equilibrium sets of an intrinsic common agency game with discrete types and direct revelation mechanisms. After presenting a general algorithm to find the pure-strategy equilibria of this game, we use it to characterize these equilibria when the two principals...

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...
