The course has two primary objectives. First, it explores the standard tools of modern empirical economic research, beginning with the linear regression model and then moving to more advanced methods such as generalized least squares, two-stage least squares, and maximum likelihood estimation. Second, it aims at sharpening your understanding of the prospects for, and limitations of, valid causal inferences from observational data. Tutorial exercises and case studies from the literature offer hands-on experiences in utilizing these concepts and methods. The language of instruction is English.
