This paper shows that the informativeness principle does not automatically extend to settings with limited liability. Even if a signal is informative about effort, it may have no value for contracting. An agent with limited liability is paid zero for certain output realizations. Thus, even if...

The informativeness principle demonstrates qualitative benefits to increasing signal precision. However, it is difficult to quantify these benefits -- and compare them against the costs of precision -- since we typically cannot solve for the optimal contract and analyze how it changes with...

This paper shows that the informativeness principle, as originally formulated by Holmstrom (1979), does not hold if the first-order approach is invalid. We introduce a "generalized informativeness principle" that takes into account non-local incentive constraints and holds generically, even...

We consider a simple trading relationship between an expectation-based loss-averse buyer and profit-maximizing sellers. When writing a long-term contract the parties have to rely on renegotiations in order to ensure materially efficient trade ex post. The type of the concluded long-term contract...

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...

In the property rights approach to the theory of the firm (Hart, 1995), parties bargain about whether or not to collaborate after non-contractible investments have been made. Most contributions apply the regular Nash bargaining solution. We explore the implications of using the generalized Nash...

Consider a non-governmental organization (NGO) that can invest in a public good. Should the government or the NGO own the public project? In an incomplete contracting framework with split-the-difference bargaining, Besley and Ghatak (2001) argue that the party who values the public good most...

We analyze a long-term contracting problem involving common uncertainty about a parameter capturing the productivity of the relationship, and featuring a hidden action for the agent. We develop an approach that works for any utility function when the parameter and noise are normally distributed...

We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off; between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

Contractual execution generates hard information, available to the contracting parties, even when contracts are secretly executed. Building on this simple observation, the paper shows that incomplete contracts can be preferred to complete contracts. This is because (i) execution of incomplete...
