中国人民大学徐晓宇在汉青经济与金融高级研究院作了一场题为“Scale, Skill, and Team Management:Organizational Structure of Mutual Fund Families(规模、技能和团队管理对共同基金的家庭组织结构)”的讲座。
中国人民大学汉青经济与金融高级研究院设经济学和金融学两个实验班,采取三年制硕士学习周期,旨在培养学术型与实用型并重的一流经济与金融人才。联合招生,独立培养:研究院与中国人民大学经济学院、财政金融学院联合招生,研究院制定培养方案,对所有学生独立培养。
我们开发的委托投资组合管理的模式与代理问题两层,获得使用基金数据单经理与团队资金的影响,以及测试模型的影响。有两个经理团队的基金总是可以作为两路独立经营的资金和报告的综合性能。因此,一个团队的基金应该有一个风险调整后的业绩至少不如两个子基金,以加权平均的预期收益和更低的风险,由于多元化。然而,在现实中,我们经常看到球队的资金降低性能。我们的模型解释了原因。基金的家庭最佳选择风险共担合同,为自己的球队资金,最大限度地发挥自己的利润。因此,更好的技能的管理人员不愿意加入团队。基金家族设计合同诱导的单经理和团队的资金组合,以最大化自己的利润,这是最大限度地提高基金业绩的投资者不同。此外,家有更多的凸补偿(例如,由于凸资金流)优化选择的团队管理基金的比例较低,并具有较低的平均表现。我们发现我们的模型的实证证据相一致单曲关于团队管理和基金业绩的预测。

原文:We develop a model of delegated portfolio management with two layers of agency problems, derive implications for single-manager vs. team funds, and test model implications using mutual fund data. A team fund with two managers can always operate as two separately-run funds and report the combined performance. Thus, a team fund should have a risk-adjusted performance at least as good as the two sub funds, with weighted average expected returns and lower risk due to diversification. Yet in reality we often observe lower performance for team funds. Our model explains why. Fund families optimally choose risk sharing contracts for their team funds to maximize their own profit. As a result, better skilled managers prefer not to join a team. Fund families design contracts to induce a mix of single-manager and team funds to maximize their own profit, which is different from maximizing fund performance for investors. Moreover, families with more convex compensation (e.g., due to convex fund flows) optimally choose a lower fraction of team-managed funds and have a lower average performance. We find empirical evidence consistent with our model`s predictions regarding team management and fund performance.
