We propose a new method to disentangle individual from team productivity, CoScore. CoScore uses the varying membership and levels of success of all teams to simultaneously infer an individual’s productivity and her credit for each of her teams’ successes. Crucially, the productivities of all individuals are determined endogenously via the solution of a fixed point problem. We show that CoScore is well defined, and we provide axiomatic foundations for the inferred credit allocation. We illustrate CoScore in scientific research and sports.
