Frontiers in Operations: You, Me, or We? Coproductive Principal-Agent Dynamics
研究项目发起人是否应与代理人组建团队，以及均衡下是单人执行、委托执行还是联合执行，发现发起人因项目囤积而组建团队不足，且联合执行过少。
Problem definition: Projects are often initiated by a single person—a principal—who then decides whether to form a team by sharing project value with an agent. We ask the following: When does a principal form a team, and which operating mode emerges in equilibrium—single execution by the principal, delegated execution to the agent, or joint execution? Methodology/results: We consider a coproductive principal-agent model with endogenous team formation. In the second best, joint execution is less frequent than optimal, whereas both single and delegated execution are chosen too much. With a linear contract, common with nonfinancial output (credits, coauthorship) or in entrepreneurial ventures, there is too much single execution; that is, the principal does not form a team often enough, and there is either too little joint execution when one of the workers has low productivity or too little delegation otherwise. Overall, the inefficiency in project execution (due to moral hazard) appears less severe than the inefficiency in the principal’s team formation decision (due to project hoarding). Managerial implications: Managerial under-delegation fundamentally stems from project hoarding; that is, principals do not partner enough. When principals choose to form a team, they then might delegate too much; paradoxically, this happens when agents have low productivity. Although the existing literature focuses on eliciting agent effort for a given operating mode, our analysis suggests the decision to form a team (or not) is a more critical issue.
