Talent Heterogeneity, Task Substitutability, and Effort Allocation in Teams

This paper studies cooperation and defection in teams when workers differ in talent and tasks vary in their degree of substitutability. We consider an organizational environment in which workers receive equal shares of team output, the principal allocates workers to teams, and a minimum effort standard is enforced through monitoring. Using a CES production technology, we characterize the equilibrium effort profiles that emerge under different combinations of task technology, talent heterogeneity, and effort standards. Mutual cooperation is most likely when workers have similar talent levels and tasks are complementary, whereas mutual defection becomes more prevalent as substitutability increases. Most importantly, asymmetric effort equilibria arise only when talent heterogeneity interacts with a production technology that departs from the Cobb–Douglas benchmark. Under substitutability, the more talented worker tends to cooperate while the less talented worker defects; under complementarity, the opposite pattern may emerge. The paper contributes by identifying a technological condition for asymmetric effort allocation in teams. More broadly, the results show that free riding may emerge as an equilibrium response to task technology and team composition rather than as a simple consequence of weak incentives. From the principal's perspective, profits depend more on team composition and task technology than on the strictness of effort standards, and asymmetric effort allocation may represent a stable and profitable organizational outcome.
