This paper considers a principal-agent model with adverse selection, in which collusion among the agents is possible. We compare the optimal outcome in two cases: (i) the principal can perfectly discriminate the transfers to the agents, and (ii) the principal's power to discriminate the...

This paper considers a principal-agent model with adverse selection and limited wage discrimination. Under wage compression, an agent may have an incentive to free ride on other agents by manipulating his private information. When collusion among the agents is not possible, the principal...

Adverse selection induces economic limits to market substitution. If quality uncertainty persists in both internet and traditional marketplaces, a second-best equilibrium with parallel market segments may arise. Positive trade in parallel segments implies that the information cost advantage of...

The European Union's Directive on the Harmonization of the national warranty law directed interest to this particular legal institution. From an economic point of view warranties have different functions. In this paper warranties' main features, their role in adverse selection settings and as a...

We develop a dynamic model in which a group collectively bargains with an external party. At each date the group makes an offer to the external party (the 'agent') in exchange for a concession. Group members hold heterogeneous preferences over agreements and are uncertain about the agent's...

In a vertical market in which downstream firms have private information about their productivity and compete for consumers, an upstream firm posts public bilateral contracts. When downstream firms are risk-neutral without wealth constraints, the upstream firm offers the input to all retailers....
