Reward systems based on balanced scorecards typically connect pay to an index, i.e. a weighted sum of multiple performance measures. We show that such an index contract may indeed be optimal if performance measures are non-verifiable so that the contracting parties must rely on self-enforcement....

The paper analyzes conditions for implementing incentive schemes based on, respectively joint, relative and independent 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...

We analyze relational contracts for a set of agents when either (a) only aggregate output or (b) individual outputs are observable. A team incentive scheme, where each agent is paid a bonus for aggregate output above a threshold, is optimal in case (a). The team's efficiency may increase...
