摘要翻译:
我们定义了什么是“价格影响”的含义,以及如何衡量和建模在最近的文献。虽然这个概念似乎传达了一个强有力的直觉机制的想法,但我们讨论了为什么事情可能不那么简单。实证研究表明,虽然签订的订单流量与价格变化之间的相关性很强,但交易对价格的影响既不是线性的,也不是永久性的。冲击允许私人信息反映在价格中,但同样的道理,订单流的随机波动也一定会导致市场的波动。

英文摘要:
We define what "Price Impact" means, and how it is measured and modelled in the recent literature. Although this notion seems to convey the idea of a forceful and intuitive mechanism, we discuss why things might not be that simple. Empirical studies show that while the correlation between signed order flow and price changes is strong, the impact of trades on prices is neither linear in volume nor permanent. Impact allows private information to be reflected in prices, but by the same token, random fluctuations in order flow must also contribute to the volatility of markets.
