Analysis of Panel Data
The course provides an introduction into panel data analysis. After a discussion of the advantages (and disadvantages) of repeated measurements of the same units (“panel data”), the course introduces the fixed and random effects estimators and discusses their underlying assumptions. The second part of the course focuses explicitly on causal analysis using panel data. The canonical difference-in-differences approach is presented together with recent extensions, including the method of synthetic controls and the case of staggered treatment timings. The lecture will be accompanied by a hands-on-sessions, in which students will learn how to implement the discussed panel data methods and estimators in statistical software.
