In a setting in which agents are involved in both team and individual production, we provide conditions under which the(More)
This paper studies implementation in a principal-agent model of adverse selection. We explore ways in which the additional structure of principal-agent models (compared to general implementation models) simplifies the implementation problem. We develop a connection between the single crossing property and monotonicity conditions which are necessary for Nash(More)

Conventional wisdom suggests that a firm will not buy an input for a price above its in-house cost of production. We show that this is not necessarily the case when a monopolistic input supplier also serves the firm's retail rival. In this case,(More)
