Artificial Intelligence in Team Dynamics: Who Gets Replaced and Why? (2506.12337v1)

Abstract: This study investigates the effects of AI adoption in organizations. We ask: (1) How should a principal optimally deploy limited AI resources to replace workers in a team? (2) In a sequential workflow, which workers face the highest risk of AI replacement? (3) How does substitution with AI affect both the replaced and non-replaced workers' wages? We develop a sequential team production model in which a principal can use peer monitoring -- where each worker observes the effort of their predecessor -- to discipline team members. The principal may replace some workers with AI agents, whose actions are not subject to moral hazard. Our analysis yields four key results. First, the optimal AI strategy involves the stochastic use of AI to replace workers. Second, the principal replaces workers at the beginning and at the end of the workflow, but does not replace the middle worker, since this worker is crucial for sustaining the flow of information obtained by peer monitoring. Third, the principal may choose not to fully exhaust the AI capacity at her discretion. Fourth, the optimal AI adoption increases average wages and reduces intra-team wage inequality.
