This paper constructs a revelation mechanism to address a problem of moral hazard under soft information. The agent alone observes the stochastic outcome of her action, which she reports to the principal. Therefore the principal also faces a problem of ex post adverse selection. Economically...

Two principals engage in Hotelling competition for an agent's services under incomplete information as to her outside option (location). This renders the agent's participation decision probabilistic from the perspective of each principal. Regardless of the market structure at equilibrium the...

We study a continuous time contracting problem with risk taking in which size plays a role. The agent may take on excessive risk to enhance short-term gains; doing so exposes the principal to large, infrequent (poisson) losses. The optimal contract must use size as an instrument; there is...

Principals seek to enter into a productive relationship with agents by posting mechanisms in a market with competitive search. A mechanism includes an incentive contract if the meeting is bilateral, and an ex post bidding process, in which agents make contract offers, if several agents meet the...

We study a continuous-time contracting problem in which size plays a role. The agent may take on excessive risk to enhance short-term gains; doing so exposes the principal to large, infrequent losses. The optimal contract includes size as an instrument: downsizing along the equilibrium path may...

We model a duopoly in which two-sided platforms compete on both sides of a two-sided market. Platforms (or intermediaries) select the quality they offer consumers, and the prices they charge to consumers and firms. In this model, non-trivial competition on both sides induces non-quasiconcave...

I study a simple model of moral hazard with soft information. The risk-averse agent takes an action and she alone observes the stochastic outcome; hence the principal faces a problem of ex post adverse selection. With limited instruments, the principal cannot solve these two problems...

I study a model of moral hazard with soft information: the agent alone observes the stochastic outcome of her action; hence the principal faces a problem of ex post adverse selection. With limited instruments the principal cannot solve these two problems independently; the ex post incentive for...
