The Microstructure Exchange is a virtual academic market microstructure research seminar of indefinite length, intended to continue the sharing of ideas between researchers.
Speakers will be invited to present their work over Zoom. Seminars will last 45 minutes with questions asked at designated break points during the talk and a 15 minute Q&A session at the end of the session that will be organized by a moderator.
Passive Investing and Price Efficiency
Discussant: Gideon Saar (Cornell University)
August 11th, 11 am (EDT)
Abstract: The growth of index funds and ETFs has raised concerns that the increased participation of uninformed investors may harm price efficiency. Modeling passive investment strategies as optimal strategies without private information, this paper studies the question in a theoretical framework, in which investors optimally decide whether to participate in the financial market and whether to choose informed or uninformed managers. There are two main results. First, the decrease in the passive management fees, which increases the share of passive investments in equilibrium, in fact makes prices more efficient when informed managers trade strategically. Second, when asset fundamentals are correlated via a factor structure, the factor portfolio can be the most liquid and the least efficient portfolio, making it the most valuable for both active and passive managements.
Seminars will take place on Tuesdays. Times may vary to accomodate a broader global audience and to meet the speaker’s schedule.
The calendar is available as a Google calendar or in iCal format.

The Microstructure Exchange will host resources, tools, and data for microstructure researchers. Please contact firstname.lastname@example.org to add your resource to this section.
- Spread statistics from Sunil Wahal. The dataset contains nanosecond precision spreads (using four methodologies) of all common stocks and ETFs with valid data. See Conrad and Wahal (2020) for more information.
- Quote-to-trade ratios from the paper Quoting activity and the cost of capital by Ioanid Rosu, Elvira Sojli, and Wing Wah Tham. Wharton Research Data Services (WRDS) data was used in preparing this output.
- The Microstructure Online Seminars Asia Pacific series hosts previous Microstructure Exchange speakers at times that better match the Australia, Hong Kong, and Singapore time zone.
- The Summer School on Market Microstructure, presented by Thierry Foucault and Albert Menkveld, will be hosted on June 7-11, 2021 at Stockholm Business School. It is a one-week intensive course, suitable for PhD students and advanced practitioners.
- The Leibniz Institute for Financial Research SAFE is organizing the 4th SAFE Market Microstructure Conference to stimulate the discussion on current developments in the field. The three-day conference will be held on the 17-19 August 2020 online.
