摘要

This paper studies an otherwise standard principal-agent problem with hidden information, but where there are positive production externalities between agents: the output of any agent depends positively on the effort expended by other agents. It is shown that the optimal contract for the principal exhibits two-way distortion: the effort of any agent is oversupplied (relative to the first-best) when his marginal cost of effort is low, and undersupplied taken his marginal cost of effort is high. This pattern of distortion cannot otherwise arise in optimal single- or multi-agent incentive contracts. unless there are countervailing incentives. However, unlike the countervailing incentives case, the pattern of distortion we find is robust to the precise form of the externality.
