This paper provides a non-technical discussion of the incomplete contracting approach to the theory of the firm developed by Grossman and Hart (1986). This approach offers an answer to the questions regarding the boundaries of the firm first raised by Coase (1937).

The theory of contracts is one of the most active research areas in economics. While classic contract theory failed to account for institutions such as property rights and authority, the theory of incomplete contracts has overcome these conceptual problems and produced a variety of interesting...

Kolstad, Ulen and Johnson (1990) have conjectured that exclusive use of negligence liability leads to suboptimal choice of precaution in the presence of uncertainty and that ex ante regulation can correct these inefficiencies. We complete their argument by making a mild additional premise.

In a pioneering approach towards the explanation of the phenomenon of "yes man" behavior in organizations, Prendergast (1993) argued that incentive contracts in employment relationships generally make a worker distort his privately acquired information. This would imply that there is a trade-off...

This paper offers a non-technical discussion of the literature on the theoretical foundations of the incomplete contracting approach.

The government wants two tasks to be performed. In each task, unobservable effort can be exerted by a wealth-constrained private contractor. If the government faces no binding budget constraints, it is optimal to bundle the tasks. The contractor in charge of both tasks then gets a bonus payment...

An inventor can invest research effort to come up with an innovation. Once an innovation is made, a contract is negotiated and unobservable effort must be exerted to develop a product. In the absence of liability constraints, the inventor's investment incentives are increasing in his bargaining...

Principal-agent models in which the agent has access to private information before a contract is signed are a cornerstone of contract theory. We have conducted an experiment with 720 participants to explore whether the theoretical insights are reflected by the behavior of subjects in the...

An agent can make an observable but non-contractible investment. A principal then offers to collaborate with the agent to provide a public good. Private information of the agent about his valuation may either decrease or increase his investment incentives, depending on whether he learns his type...
