摘要

监管机构使用对高订单交易比率(OTR)收取费用等措施来减缓高频交易。然而，它们对市场质量的影响好坏参半。我们研究了印度股票市场的一个自然实验，在这个实验中，这种费用被引入了两次，在动机和实施上都有所不同。利用差中差方法，我们发现当对所有订单征收时，费用降低了OTR并改善了市场质量，而当对某些订单有选择地征收时，费用几乎没有影响。流动性的改善是由于OTR降低后逆向选择成本的降低。

When is the order-to-trade ratio fee effective?

Regulators use measures such as a fee on high order-to-trade ratio (OTR) to slow down high-frequency trading. Their impact on market quality is, however, mixed. We study a natural experiment in the Indian stock market where such a fee was introduced twice, with differences in motivation and implementation. Using a difference-in-difference approach, we find that the fee decreased OTR and improved market quality when it was imposed on all orders, while it had little effect when it was imposed selectively on some orders. Improvement in liquidity was driven by a reduction in adverse selection costs following lower OTR.
