Ockenfels, Axel; Sliwka, Dirk; Werner, Peter - 2024

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...
