英文摘要:
We analyze a family of portfolio management problems under relative performance criteria, for fund managers having CARA or CRRA utilities and trading in a common investment horizon in log-normal markets. We construct explicit constant equilibrium strategies for both the finite population games and the corresponding mean field games, which we show are unique in the class of constant equilibria. In the CARA case, competition drives agents to invest more in the risky asset than they would otherwise, while in the CRRA case competitive agents may over- or under-invest, depending on their levels of risk tolerance.

中文摘要:
我们在相对绩效标准下分析了一系列投资组合管理问题,这些问题是针对拥有CARA或CRRA公用事业并在对数正常市场中的共同投资期内交易的基金经理。我们构造了有限总体对策和相应的平均场对策的显式常数均衡策略,我们证明了它们在常数均衡类中是唯一的。在CARA案例中,竞争促使代理人在风险资产上的投资超过其他情况,而在CRRA案例中,竞争代理人可能过度投资或投资不足,这取决于他们的风险承受能力。
