This paper shows that the informativeness principle, as originally formulated by Holmstrom (1979), does not hold if the first-order approach is invalid. We introduce a "generalized informativeness principle" that takes into account non-local incentive constraints and holds generically, even...

This paper studies multi-agent optimal contracting with cost synergies. We model synergies as the extent to which effort by one agent reduces his colleague's marginal cost of effort. An agent's pay and effort depend on the synergies he exerts, the synergies his colleagues exert on him and,...

This paper shows that the informativeness principle does not automatically extend to settings with limited liability. Even if a signal is informative about effort, it may have no value for contracting. An agent with limited liability is paid zero for certain output realizations. Thus, even if...

The informativeness principle demonstrates qualitative benefits to increasing signal precision. However, it is difficult to quantify these benefits -- and compare them against the costs of precision -- since we typically cannot solve for the optimal contract and analyze how it changes with...

Many organizations rely on teamwork, and yet field evidence on the impacts of team-based incentives remains scarce. Compared to individual incentives, team incentives can affect productivity by changing both workers’ effort and team composition. We present evidence from a field experiment...

We present evidence from a firm level experiment in which we engineered an exogenous change in managerial compensation from fixed wages to performance pay based on the average productivity of lower-tier workers. Theory suggests that managerial incentives affect both the mean and dispersion of...

We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength...

We use personnel data to compare worker productivity under a relative incentive scheme, where worker pay is negatively related to the average productivity of co-workers, with productivity under piece rates – where pay is based on individual productivity alone. We find that for the average...
