This paper provides new analytical tools for studying principal-agent problems with adverse selection and limited commitment. By allowing the principal to use general communication devices we overcome the literature's common, but overly restrictive focus on one-shot, direct communication. In...

We study the optimal hierarchical structure of an organization under limited commitment. The organization cannot make a long term commitment to wages and output levels, while it can commit to its hierarchical structure. We show that the optimal hierarchical structure is horizontal when it is...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004: This paper provides an analytical framework for studying principal-agent problems with adverse selection and limited commitment. By allowing the principal to use noisy communication we solve two fundamental problems of...

Crowdfunding provides the innovation that, before the investment, entrepreneurs contract with consumers. Under demand uncertainty, this improves a screening for valuable projects. Entrepreneurial moral hazard threatens this benefit. Focusing on the trade-off between value screening and moral...

This note relates the mechanisms that are based on mediated contracts of Rahman and Obara (2010) to the mechanisms of Myerson (1982). It shows that the mechanisms in Myerson (1982) are more general in that they encompass the mechanisms based on mediated contracts. It establishes an equivalence...

We study the reasons and conditions under which mediation is beneficial when a principal needs information from an agent to implement an action. Assuming a strong form of limited commitment, the principal may employ a mediator who gathers information and makes non-binding proposals. We show that...
