In a public good environment with positively correlated types, we characterize optimal mechanisms when agents have private information and can enter collusive agreements. First, we prove a weak-collusion-proof principle according to which there is no restriction for the principal in offering...

We propose a theory of supervision with endogenous transaction costs. A principle delegates part of his authority to a supervisor who can acquire soft information about an agent's productivity. If the supervisor were risk-neutral, the principal would simply make the better informed supervisor...

A risk averse agent gathers information on productivity shocks and produces accordingly on behalf of his principal. Information gathering is imperfect so that the agent has either complete or no knowledge at all of those shocks. The model allows for moral hazard in information gathering, private...

Since the 1980s, privatization of formerly state-owned firms has been extensively implemented by governments across Latin America. Despite the fact that most evaluations of the process fail to find significant adverse efficiency and welfare effects, there has been a strong surge in public...

We analyze contracting between an innovator endowed with an idea and a project developer. The innovator has private information about the value of his idea, whereas the developer must exert some non-verifiable effort at the development stage. The developer may also threaten to leave the...

Economic theory claims that contracts renegotiation prevents from reaching the informationally constrained efficient solution that could have been obtained under full commitment. Assessing the cost of renegotiation compared to the full commitment scenario still remains an open issue from an...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...
