How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiationproofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

Consumer surplus in a market is affected by how the market is segmented. We study the maximum consumer surplus across all possible segmentations of a given market served by a multi product monopolist. We characterize markets for which the maximum consumer surplus equals a first best benchmark...

We investigate a common-value labor setting in which firms interview a worker prior to hiring. When firms have private information about the worker’s value and interview decisions are kept private, many firms may enter the market, interview, and hire with positive probability. When firms’...

I show that a unique equilibrium exists in a two-player all-pay auction with asymmetric independent discrete signal distributions and asymmetric interdependent valuations. The proof is constructive, and the construction is simple to implement as a computer program. For special cases, which...
