We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

Contractual execution generates hard information, available to the contracting parties, even when contracts are secretly executed. Building on this simple observation, the paper shows that incomplete contracts can be preferred to complete contracts. This is because (i) execution of incomplete...

Consider a seller and a buyer who write a contract. After that, the seller produces a good. She can influence the expected quality of the good by making unobservable investments. Only the seller learns the realized quality. Finally, trade can occur. It is always ex post efficient to trade. Yet,...

We study the effect of additional private information in an agency model with an endogenous information structure. If more private information becomes available to the agent, this may hurt the agent, benefit the principal, and affect the total surplus ambiguously.

We formulate and estimate a structural model for travel demand, in which users have heterogeneous preferences and make their transport decisions considering the network congestion. A key component in the model is that users have incomplete information about the preferences of other users in the...

In a complete contracting model, a risk-neutral seller exerts effort while producing a good. Effort is a hidden action and stochastically influences the risk-neutral buyer's valuation. Then the buyer can gather private information about his valuation. The ex ante optimal contract may encourage...

This paper analyses the relation between authority and incentives. It extends the standard principal--agent model by a project selection stage in which the principal can either delegate the choice of project to the agent or keep the authority. The agent's subsequent choice of effort depends both...
