My co-author Stanford-based economist Jenny Kuan and I each traveled to different parts of the country recently to present our research on the problematic changes in stock market structures. I presented the paper at the meetings of SASE held at Northwestern’s Kellogg School of Business and Jenny presented the paper at the ISNIE meetings at Duke. We got helpful comments from both events and are honing in on a new draft for submission to a peer reviewed finance journal. Here are the slides I used in Chicago.
