Market Liquidity and Competition Among Designated Market Makers
利用巴黎泛欧交易所数据，研究发现指定做市商合同设计的外生变化显著降低了报价价差和有效价差，且做市商间竞争越激烈，流动性改善越大。
Do competition and incentives offered to designated market makers (DMMs) improve market liquidity? We employ data from NYSE Euronext Paris to show that exogenous changes in contract design lead to significant decreases in quoted and effective spreads. In particular, market liquidity increases the most for stocks with the largest increase in competition among DMMs. Our analysis shows that competition among DMMs is an important aspect of contract design, along with elements such as rebates and requirements.
