The Microstructure Exchange is a virtual academic market structure research seminar series of indefinite length, intended to continue the sharing of ideas between researchers.

Speakers are invited to present their work over Zoom. Seminars last for about an hour, consisting of a 45-minute presentation followed by a 15-minute Q&A. Questions can also be asked during the presentation, at designated break points or on the fly, depending on the speaker’s preference.

Abstract: We examine the impact of increasing competition among the fastest traders by analyzing a new low-latency microwave network connecting exchanges trading the same stocks. Using a difference-in-differences approach comparing German stocks with similar French stocks, we find improved market integration, faster incorporation of stock-specific information, and an increased contribution to price discovery by the smaller exchange. Liquidity worsens for large caps due to increased sniping but improves for mid caps due to fast liquidity provision. Trading volume on the smaller exchange declines across all stocks. We thus uncover nuanced effects of fast trader participation that depend on their prior involvement.

Calendar

Seminars take place on Tuesdays at 11:00.000000 a.m., NYSE time (or, if you are at IEX, at 11:00.000350 a.m.).
