Worker Self-Selection and the Profits from Cooperation
研究竞争性劳动力市场中的团队生产，发现工人会自我选择进入不同企业，而雇佣合作型工人的企业能获得严格正利润，因为合作提高产出且工资较低。
We investigate a competitive labor market with team production. Workers differ in their motivation to exert team effort, and types are private information. We show that there can exist a separating equilibrium in which workers self-select into different firms and firms employing cooperative workers make strictly positive profits. Profit differences across firms persist because cooperation strictly increases output and worker separation requires firms employing cooperative workers to pay out weakly lower wages.
