The Rise of Research Teams: Benefits and Costs in Economics
经济学研究越来越多以团队形式进行，团队成果影响力更大。本文分析了团队合作的收益（如知识整合）和成本（如模糊个人贡献、影响职业发展），并探讨了借鉴硬科学的制度创新来平衡利弊。
Economics research is increasingly performed in teams, and team-authored work has a large and increasing impact advantage. This article considers the benefits and costs of this “rise of teams.” Among its benefits, teamwork allows individuals to aggregate knowledge in productive and novel ways. For example, as knowledge accumulates over time, individuals become narrower in their expertise, and teamwork is a natural organizational approach to aggregating expertise and maintaining one’s reach. But teamwork also brings costs. For example, teamwork divides and obscures credit, which is central to the reward system of science. By clouding credit assignment, teamwork can undermine individual career progression and exacerbate issues of bias. In addressing the rise of teamwork, this paper further considers institutional innovations, especially those inspired by the hard sciences, that can help limit the costs teamwork imposes while realizing the benefits.
