The objective of this course is to prepare the Ph.D. students in economics for the study of empirical macroeconomics, by providing a rigorous introduction to the theory and practice of time series analysis (univariate as well as multivariate time series, and stationary as well as non-stationary time series).

Each week a number of theoretical and/or empirical exercises will be assigned as homework. The theoretical homework serves as preparation for the midterm and final exams, and the empirical homework will prepare you for the term paper.

The final grade will be determined by the homework (10%), a written closed-book mid-term exam (30%), a written closed-book final exam (30%), and an empirical term paper (30%). The final exam will cover the material of the mid-term exam as well. If you score higher on the final exam than on the mid-term exam, the latter score will be ignored, and the final exam will count for 60% of the final grade. The term paper is due on the final exam date.
