Executive Summary

This intensive two-week course delves into advanced techniques for analyzing dynamic panel data models, equipping participants with the skills to address complex econometric challenges in longitudinal data. The course covers GMM estimators (Difference and System), addressing endogeneity, non-stationarity, and heterogeneity, and robust inference methods. Real-world applications, coding labs in Stata and R, and hands-on exercises will solidify understanding. Participants will also explore advanced topics like dynamic common correlated effects models and panel VARs. By the end of the course, attendees will be able to critically evaluate and apply appropriate panel data methodologies to address causal questions in economics, finance, and social sciences, and present the results in a professional manner.

Introduction

Panel data, which combines cross-sectional and time-series data, offers powerful tools for addressing research questions in economics, finance, and other fields. Dynamic panel data models, where lagged dependent variables are included as regressors, present unique challenges due to endogeneity and potential biases. This advanced course focuses on addressing these challenges by providing a rigorous treatment of modern econometric techniques for dynamic panel data. Participants will learn how to estimate and interpret dynamic panel data models using Generalized Method of Moments (GMM) estimators. They will also learn to account for unobserved heterogeneity, and cross-sectional dependence. Furthermore, the course emphasizes the importance of appropriate diagnostic testing and robust inference methods. This course will provide participants with the theoretical foundations and practical skills necessary to conduct cutting-edge research using dynamic panel data.
