EC5102 Macroeconomic Theory
Instructor: Zhang Jie
Course Description:
This course is designed to provide modern macroeconomic models which are essential in
the study of economics at the graduate level. The course will develop the key models and
techniques in use in modern macroeconomics. The course materials will analyze the
general equilibrium foundations and the two welfare theorems, infinitely lived
representative agent models, the overlapping-generations model, and models with
incomplete markets and risk sharing. The course will concentrate on dynamic
optimization in both discrete and continuous time. The models will be used to study
growth theory, business cycles, certain components of aggregate demand, and monetary
and fiscal policies.
Readings: There is no good textbook that covers the material of the course
systematically. The books of Azariadis, Blanchard and Fischer, Dana and Le Van,
Romer, and Stokey and Lucas cover parts of the material and are to be used as
supplementary material. There are some lecture notes available on the web which better
cover the material. In particular, the lecture notes Krueger (2007) and Krusell (2007) will
be used as the primary references. As the course progresses, you will also be assigned
journal articles to read. There are several books on dynamic optimization that treat
dynamic programming and maximum principle in different levels of generality and may
be used for reference purposes.
The instructor will upload notes to the IVLE web site for each lecture a few days in
advance.
