A firm, privately informed about product quality, chooses a public test. Tests vary in expertise, and return a binary result. A competitive market generates interim beliefs based on expertise and posteriors based on test results. We show that standard single-crossing does not hold. Higher...

It is well known that when players have private information, vis a vis the designer, and their preferences coincide it is hard to implement the socially desirable outcome. We show that with arbitrarily small fines and arbitrarily noisy inspections, the social choice correspondence can be fully...

We consider the regulation of a monopoly facing consumers that may evade payments, an important issue in public utilities. To maximize total surplus, the regulator sets the price and socially costly transfers, ensuring that the monopoly breaks-even. With costly effort, the firm can deter...

This paper investigates under which circumstances negotiating simultaneously over multiple issues or assets helps reduce inefficiencies due to the presence of asymmetric information. We find that a simultaneous negotiation over multiple assets that are substitutes reduces inefficiencies. The...

This paper studies revenue maximizing auctions when buyers' outside options depend on their private information. The set-up is very general and encompasses a large number of potential applications. The main novel message of our analysis is that with type-dependent non-participation payouts, the...

This paper studies revenue-maximizing allocation mechanisms for multiple goods where the buyer's utility can depend non-linearly in his type. We point out that despite strictly increasing virtual utilities, the allocation rule obtained via pointwise optimization may fail to be increasing and...
