Book Econometric Analysis of Cross Section and Panel Data By Wooldridge - Overview

My interest in panel data econometrics began in earnest when I was an assistant professor at MIT, after I attended a seminar by a graduate student, Leslie Papke, who would later become my wife. Her empirical research using nonlinear panel data methods piqued my interest and eventually led to my research on estimating nonlinear panel | ECONOMETRIC ANALYSIS OF CROSS SECTION AND PANEL DATA Econometric Analysis of Cross Section and Panel Data Jeffrey M.
