We compare evaluations of employee performance by individuals and groups of supervisors, analyzing a formal model and running a laboratory experiment. The model predicts that multi-rater evaluations are more precise than single-rater evaluations if groups rationally aggregate their signals about...

We implement a laboratory experiment in which a principal has to decide on monitoring intensity and pay to investigate whether they are complements or substitutes. Wage level, monitoring intensity, and consequently the desired enforceable effort level are jointly determined by the maximization...
