The analysis of adverse selection problems in seller-buyer relationships has typically been based on the assumption that private information is uncertifiable, while in practice it may well be certifiable. If a buyer has certifiable private information, he can conceal evidence, but he cannot...

In the Grossman-Hart-Moore property rights approach to the theory of the firm, it is usually assumed that information is symmetric. Ownership matters for investment incentives, provided that investments are partly relationship-specific. We study the case of completely relationship-specific...

"Implicit Contracts, incentive compatibility, and involuntary unemployment" (MacLeod and Malcomson, 1989) remains our most highly cited work. We briefly review the development of this paper and of our subsequent related work, and conclude with reflections on the future of relational contract...

When partnerships come to an end, partners must find a way to efficiently reallocate the commonly owned assets to those who value them the most. This requires that the aforementioned members possess enough financial resources to buy out the others’ shares. I investigate ex post efficient...

This paper studies a monopsonistic firm's optimal employment contracts if workers have private information on both their propensity for social comparisons and their ability. Employees of the firm are taken to form their own distinct reference group. It is shown that screening workers with equal...

The principal management theoretical lenses for examining leveraged buyouts have been the agency theory and information asymmetries. Occasionally a wider number of theories and concepts have been invoked, such as the parenting advantage, the resource-based view, and the market for corporate...
