New Economics School
Macroeconomics Module 5, 2012
Dmitriy Stolyarov
Overview of the course
This is a course in macroeconomic modeling with a focus on business cycles, money and
unemployment. To understand the mechanisms underlying these macroeconomic phenomena,
modern economists are using fully specified equilibrium models that have “microeconomic
foundations” and feature explicit dynamics. We will cover the basic macroeconomic models that
are used to understand fluctuations of economic activity over the business cycle, the possible role
of money in the economy and the functioning of decentralized labor markets. The course will
cover the relevant aspects of theory and will pay particular attention to evaluating the empirical
success of these models. In the process, the students will be familiarized with a set of basic tools
used in modern macroeconomic modeling.
Course requirement and grading
There will be a midterm exam (40% of the final grade) and a final exam (60% of the final grade).
Passing the course requires all students to take two exams (at their regularly scheduled times),
unless an exam is missed for a documented reason approved by NES administration. There is no
make up for the midterm exam; if the midterm exam is missed for an approved documented
reason, 100% of the final grade will be based on the final exam.
In addition, you will be given several problem sets to help you prepare for the exams. Students
are encouraged to form study groups to work on the problem sets. Subject to teaching assistant
availability, problem sets may be collected and loosely graded (check, check plus, check minus,
zero) to give you feedback on how you keep up with the material.

Reading
Books:
As with most graduate courses in macroeconomics, there is no single text that covers all of the
topics in this course in sufficient detail, but the book by
Romer, David, Advanced Macroeconomics, 3d edition, McGraw-Hill 2006
at least includes all of the course topics in some form.
In addition, students are encouraged to consult the relevant parts of several other excellent
graduate macroeconomics textbooks:
Handbook of Macroeconomics. Edited by J. Taylor and M. Woodford. New York, NY: Elsevier,
1999. ISBN: 9780444501561.

2004.

Journal articles and notes:
Each topic in the course outline has links to relevant downloadable lecture notes authored by
well-known macroeconomists.
Some topics require you to read journal articles; required articles are listed in the course outline.
