摘要:基于基金经理人相对业绩激励机制研究,构造了一个包含有三个彼此竞争的基金经理人理论模型,分析了在相对业绩激励契约下其投资行为的特征。结果表明:基金经理人相对业绩激励契约在一定条件下会造成投资决策的扭曲,不仅会造成“羊群效应”,在某些时候还会促成非常规的冒险投资决策;应加快构建科学合理的基金经理人评价体系,为基金业健康长远发展提供更好的外部环境。

Abstract:Based on the studies of fund managers relative performance merchanism,
Study of fund managers incentives on relative performance contracts is an important part in study of fund managers incentives. In traditional models, they contain two competitive fund managers, or one fund manager taking market revenue as benchmark, ignoring the fact that a manager is generally competing with “more” opponents in the market. For better simulate the fact, this paper builds a model containing three competitive fund managers to study fund managers incentives on relative performance contracts, and recognizes that special relative performance contracts may cause unconventional investment decision or “herd behavior”. It suggests that the goverment should speed up the construction of scientific and reasonable evaluation system of fond managers, and provide a better external environment for the longterm development of the fund industry.
Key words:fund manager;relative performance contracts; incentive distortion; herd behavior
引言
在我国推出开放式基金以来,由于基金风险评价很复杂,不如排名那么直观,所以基金排名一直是对基金评价非常重要的指标。关于基金各种排名的使用已经十分广泛,基金公司使用排名来评测基金经理人的业绩、销售渠道、销售谈判筹码,投资者直接将基金排名用作选择基金的重要依据。对基金经理人和基金管理公司明确的或者隐含的相对业绩激励契约广泛存在。基金经理人的相对业绩报酬契约是指对基金投资组合实现的收益按某一收益率进行调整,根据调整后的收益率来评价基金管理人并以此作为提取报酬的依据。在这种情况下,研究相对业绩激励契约的影响具有充分的现实意义。
国内外专家学者在该领域开展了大量的研究和实践,取得了较为丰硕的成果,研究主要集中在基金经理显性激励机制和隐性激励机制两个方面。……
