随机参数市场冲击对策的FBSDE方法

An FBSDE approach to market impact games with stochastic parameters

Samuel Drapeau, Peng Luo, Alexander Schied, Dewen Xiong

摘要:

我们分析了一个市场冲击的$n$风险厌恶的代理人之间的游戏谁竞争的流动性在市场冲击模型与永久的价格影响和额外的滑点。大多数市场参数,包括波动性和漂移,都允许随机变化。我们的第一个主要结果的特点纳什均衡的一个完全耦合系统的前向倒向随机微分方程(FBSDES)。我们的第二个主要结果提供的条件下,该系统的FBSDES确实有一个唯一的解决方案,这反过来又产生了唯一的纳什均衡。在特殊情况下,我们进一步得到了封闭形式的解,并进行了数值分析

英文摘要:

We analyze a market impact game between $n$ risk averse agents who compete for liquidity in a market impact model with permanent price impact and additional slippage. Most market parameters, including volatility and drift, are allowed to vary stochastically. Our first main result characterizes the Nash equilibrium in terms of a fully coupled system of forward-backward stochastic differential equations (FBSDEs). Our second main result provides conditions under which this system of FBSDEs has indeed a unique solution, which in turn yields the unique Nash equilibrium. We furthermore obtain closed-form solutions in special situations and analyze them numerically
