Jodi Dianetti, Frank Riedel, Lorenzo Stanca

AI总结:

本文研究连续时间金融市场中具有Epstein-Zin偏好和业绩关注的交易者策略互动,通过伯努利型几何倒向随机微分方程显式推导有限及平均场博弈均衡,发现偏好显著影响均衡行为。

摘要:

我们考虑了连续时间金融市场中,具有Epstein-Zin型递归跨期偏好和业绩关注(performance concerns)的交易者之间的策略互动。基于对描述交易者最优反应的伯努利型几何倒向随机微分方程的研究,我们显式地推导了有限博弈者情形及平均场版本博弈的均衡。我们的结果表明,Epstein-Zin偏好可以导致显著不同的均衡行为。

英文摘要:

We consider the strategic interaction of traders in a continuous-time financial market with Epstein-Zin-type recursive intertemporal preferences and performance concerns. We derive explicitly an equilibrium for the finite player and the mean-field version of the game, based on a study of geometric backward stochastic differential equations of Bernoulli type that describe the best replies of traders. Our results show that Epstein-Zin preferences can lead to substantially different equilibrium behavior.
