Teamwork as a Self-Disciplining Device
研究表明，团队形成可以作为一种隐性承诺机制，帮助克服自我控制问题。当个体存在现时偏好时，团队合作通过关系契约和监控，使成员承诺更努力工作的承诺可信，从而改善绩效。
We show that team formation can serve as an implicit commitment device to overcome problems of self-control. If individuals have present-biased preferences, effort that is costly today but rewarded at some later point in time is too low from the perspective of an individual’s long-run self. If agents interact repeatedly and can monitor each other, a relational contract involving teamwork can help to improve performance. The mutual promise to work harder is credible because the team breaks up after an agent has not kept this promise, which leads to individual underproduction in the future, reducing future utility.
