英文摘要:
Using a large database of 8 million institutional trades executed in the U.S. equity market, we establish a clear crossover between a linear market impact regime and a square-root regime as a function of the volume of the order. Our empirical results are remarkably well explained by a recently proposed dynamical theory of liquidity that makes specific predictions about the scaling function describing this crossover. Allowing at least two characteristic time scales for the liquidity (`fast\' and `slow\') enables one to reach quantitative agreement with the data.

中文摘要:
利用美国股票市场上执行的800万机构交易的大型数据库,我们建立了线性市场影响机制和平方根机制之间的明确交叉,作为订单量的函数。最近提出的流动性动力学理论对描述这种交叉的标度函数做出了具体的预测,很好地解释了我们的实证结果。允许流动性至少有两个特征时间尺度(“快”和“慢”),使人们能够与数据达成定量一致。
