Team Incentives in Relational Employment Contracts

The paper analyzes conditions for implementing incentive schemes based on, respectively joint, relative and indendent performance, in a relational contract between a principal and a team of two agents. A main result is that the optimal incentive regime depends on the productivity of the agents, or more preciseley on the returns from high effort. This occurs because agents' productivites affect the principal's temptation to renege on the relational contract. The analysis suggests that we will see a higher frequency of relative performance evaluation (RPE) - and schemes that lie close to independent performace evaluation - as we move from low-productive to high-productive environments. In particular, it is shown that it effort-productivity is sufficently high, the optimal scheme for the principal is (for a range of discount factors) a collusion-proof RPE scheme, even if there is no common shock that affects the agents' output.
