We develop a microstructure model whose order flow is driven by a Cox-BESQ process. We derive important analytical properties of the Cox-BESQ process in order to explicit the stock price dynamics at different time scales, provide different parameter estimators and solve the optimal execution problem. We implement the model using a large data set of stock index and bond futures. Our results show that the Cox-BESQ process provides an alternative framework to the Hawkes process to build a microstructure model that is very flexible and has an explicit solution.

基于 Cox-BESQ 过程的简单微观结构模型,适用于最优执行策略

我们开发了一个微观结构模型,其订单流由 Cox-BESQ 过程驱动。我们推导出 Cox-BESQ 过程的重要分析特性,以明确不同时间尺度的股票价格动态,提供不同的参数估计量并解决最优执行问题。我们使用股票指数和债券期货的大型数据集来实现该模型。我们的结果表明,Cox-BESQ 过程为 Hawkes 过程提供了一个替代框架,以构建非常灵活且具有明确解决方案的微观结构模型。
