Archive: Two-Way Fixed Effects Econometrics Workshop

Presented by the Labor Seminar, Econometrics Seminar, and Michigan Ross

Co-organized by Yuehao Bai, Florian Gunsilius, Andreas Hagemann, Sara Heller, Amanda Kowalski & Basit Zafar

This workshop was held on April 1, 2022 and supported by the University of Michigan Department of Economics, MITRE, and the Ross School of Business.

The labor and econometrics seminars at the University of Michigan, in collaboration with Michigan Ross, organized a one-day applied econometrics workshop on current issues in difference-in-difference and two-way fixed effect research designs. The goal of the workshop was to help crystallize the core issues for applied researchers, define the set of recent advances, generate an engaging discussion of how the different solutions work (or don’t work) for different kinds of applied problems, and spark ideas for which open questions have the most potential for future work.
