In the model there are two types of financial auditors with identical technology, one of which is endowed with a prior reputation for honesty. We characterize conditions under which there exists a "two-tier equilibrium" in which "reputable" auditors refuse bribes offered by clients for fear of...

In deciding whether to join a coalition or not, an agent must consider both i) the expected power of the coalition and ii) her position in the vertical structure within the coalition. We establish the existence of a positive relationship between the degree of inequality in remuneration across...

We show that sellers may earn a reputation for their “ability” to deliver high-quality goods on average by honestly announcing the realized quality of items for sale every period. As the expected revenue stream from continuing with honest communication increases with their ability,...

This paper studies the impact of credit markets on optimal contracting, when the agent's "interim preference" over upcoming contracts is private information because personal financial decisions affect it via the wealth effect. The main result is a severe loss of incentive provision: equilibrium...

We analyze an entry game with multiple periods, in each period of which privately informed agents who have not joined yet decide whether to subscribe to a network, and subscribers derive benefits in future periods depending on the network size. We study the case that the agents are sufficiently...

The impact of IP protection on the innovation incentives of startup firms is examined in a dynamic model where an incumbent faces a sequence of potential startups and the incumbent's chance of winning an infringement lawsuit increases with the size of its patent portfolio. It is shown that...

I analyze and compare the effects of sequential and simultaneous cheap-talk communication (e.g., preannouncement of entry) among privately informed potential entrants who then play a normal-form entry game. The first main result is that cheap-talk communication is powerful enough to enable the...

We characterize the unique equilibrium in which high ability sellers always announce the quality of their items truthfully, in a repeated game model of experienced good markets with adverse selection on a seller's propensity to supply good quality items. In this equilibrium a seller's value...
