英文摘要:
Oft-cited causes of mini-flash crashes include human errors, endogenous feedback loops, the nature of modern liquidity provision, fundamental value shocks, and market fragmentation. We develop a mathematical model which captures aspects of the first three explanations. Empirical features of recent mini-flash crashes are present in our framework. For example, there are periods when no such events will occur. If they do, even just before their onset, market participants may not know with certainty that a disruption will unfold. Our mini-flash crashes can materialize in both low and high trading volume environments and may be accompanied by a partial synchronization in order submission. Instead of adopting a classically-inspired equilibrium approach, we borrow ideas from the optimal execution literature. Each of our agents begins with beliefs about how his own trades impact prices and how prices would move in his absence. They, along with other market participants, then submit orders which are executed at a common venue. Naturally, this leads us to explicitly distinguish between how prices actually evolve and our agents\' opinions. In particular, every agent\'s beliefs will be expressly incorrect.

中文摘要:
经常被引用的小型闪电崩盘的原因包括人为错误、内生反馈循环、现代流动性供给的性质、基本价值冲击和市场分裂。我们开发了一个数学模型,它捕获了前三种解释的各个方面。我们的框架中展示了近期微型闪存崩溃的经验特征。例如,有时不会发生此类事件。如果他们这样做了,即使是在刚开始之前,市场参与者也可能不确定会发生什么样的破坏。我们的迷你闪存崩溃可以在低交易量和高交易量环境中实现,并且可能伴随着部分同步以提交订单。我们没有采用经典的平衡方法,而是借用了最优执行文献中的观点。我们的每一位代理人都从自己的交易如何影响价格以及在他缺席的情况下价格如何变动的信念开始。然后,他们与其他市场参与者一起提交在公共场所执行的订单。自然,这会使我们明确区分价格实际如何演变和代理商的意见。特别是,每个代理人的信念都是明显错误的。
