This is the first-term doctoral seminar in econometrics for PhD students in Industrial Relations and Human Resources (IRHR). It provides students with foundational knowledge in the use of applied statistics in social science research. Much of this course will be devoted to the basic statistical techniques used in IRHR research: estimation in the classical linear regression model, corrections of these methods for some typical violations of the classical assumptions, the discrete variables model, the linear instrumental variables model, and other quantitative methods used in IRHR. Students will apply the theoretical concepts learned in the lectures to analyze empirical problems in IRHR using real data sets and statistical software.
