Two parties can at some future date 2 negotiate about whether or not to collaborate in order to generate a surplus. Yet, the negotiation stage will be reached only if at date 1 both parties pay their respective transaction costs. We show that the expected total surplus may be larger when at date...

A buyer wants to purchase an innovative good from a seller. Both parties are risk-neutral, and payments from the buyer to the seller must be non-negative. After the contract is signed, the seller privately observes a signal, which may be informative about the seller's costs. We compare two...

Contract theory is one of the most active fields of research in contemporary microeconomics. One of the reasons why it has been particularly popular in recent years may be the fact that many economists think that the incomplete contracts approach as pioneered by Grossman and Hart (1986) and Hart...

We analyze in an incomplete contracts model whether a supplier should be integrated if in addition to his investment level he chooses the degree of relationship specificity. A basic trade-off arises: While non-integration leads to higher investment incentives, potential synergies are foregone....

Prominent results of the property rights approach based on incomplete contracts as outlined by Hart (1995) say that all ownership structures lead to underinvestment and that joint ownership cannot be optimal, provided that investments are strategic complements and affect human capital only. We...

We explore the dynamic evolution of property rights regimes in R&D alliances using the incomplete contract approach pioneered by Grossman, Hart and Moore. In contrast to the standard analysis, the productive asset is an excludable public good such as a patent. Moreover, both firms can decide...

In this paper it is demonstrated that voluntary bargaining over a collective decision under asymmetric information may well lead to ex post efficiency if the default decision is non-trivial. It is argued that the default decision may be interpreted as a 'simple' contract that the parties have...

This article provides a non-technical survey on recent topics in the theory of contracts. The hold-up problem is presented and the incomplete contracts approach is discussed. Emphasis is put on conceptual problems and open questions that await further research.

We reconsider the property rights approach to the theory of the firm based on incomplete contracts. We explore the implications of different degrees of relationship-specificity when there are two parties, A and B, who can make investments in physical capital (instead of human capital). If...
