ECONOMICS 2142
TIME SERIES ANALYSIS

Syllabus

This course examines the models and statistical techniques used to study time series data in
economics. The course has two specific objectives. The first is to equip students who anticipate
using time series data in their Ph.D. research with the tools they need for state-of-the-art empirical
research. The second objective is to lay out the econometric theory of time series analysis, with an
emphasis on recent developments. Problem sets will have both theoretical and empirical
components. The substantive applications in the course will draw primarily from macroeconomics
and finance.

All the topics covered in the course are relevant to empirical applications. The course is organized
so that the most important tools for applied researchers are presented first, without unnecessary
mathematical formalities. Only a few of the papers listed under a topic will be covered; one role of
this syllabus is to list additional references for those wishing to delve into specific topics in greater
detail.

There will be two problem sets containing both theoretical and computational work, plus a final
research paper. The final grade will consist solely of your grades on the problem sets and paper
(25% weight on each problem set, 50% weight on paper). You are encouraged to work together on
the problem sets, but you should write up problem set solutions on your own. The paper should
make a new contribution to the literature on a topic of your choosing related to those covered in the
course. Unless given explicit permission otherwise, the final research paper shall be sole authored.
The paper can be either theoretical or empirical, and some topics will be suggested over the course
of the semester.

Textbooks
The primary texts are Hamilton (1994) (for models and methods) and Hayashi (2000) (for GMM
and basic limit theorems). The later sections of the course contains material not covered (at least
not well) in textbooks and draws heavily on articles. In any event, the lectures will be self-
contained.
