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: Stock markets in emerging economies often suffer from severe illiquidity. Exploiting a Chilean tax regulation, we identify a large negative causal effect of designated market maker (DMM) adoption on bid–ask spreads. A novel intraday spread distribution analysis shows that the improvement is roughly split between the DMM’s binding spread obligation and equilibrium spillovers. These spillovers arise from economies of scale in liquidity provision: tighter spreads increase trading volume, lowering liquidity suppliers’ average operating costs and enabling further tightening.

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.).

The calendar is available as a Google calendar or in iCal format.
