Overview

This course builds on principles of macroeconomics to develop a deeper comprehension of the theoretical foundations of the field, and to apply those models to real-world analysis. Current events come up throughout, and you will apply the semester's concepts to the policy questions around them.

What you should be able to do by December

  • Measure GDP as expenditure, income, and output
  • Measure unemployment and explain its costs
  • Measure inflation and explain its costs
  • Analyze the short run with the IS-LM model
  • Analyze the medium run with the IS-LM-PC model
  • Analyze the long run with the Solow model, and measure technical progress through growth accounting
  • Trace the effects of monetary and fiscal policy
  • Work through open economy macroeconomics and exchange rate determination

Prerequisites

Principles of Macroeconomics (ECON 204) and Calculus (MATH 141, MATH 155, or MATH 160).

Resources

Required textbook

Blanchard, Olivier. Macroeconomics, 9th edition. Day-One Access or a static copy is your decision. Earlier editions differ in page numbers and chapter organization.

Canvas

Assignments, slides, readings, grades, and announcements all live on Canvas, including the supplementary readings marked R1, R2, R3 in the schedule. Turn on Canvas notifications so you do not miss announcements.

Macroeconomics with Workers and Capital

Open-access companion text used for several medium-run chapters.

Morgan Library

The Services Desk provides research support (970-491-1841) and technical support (970-491-7276). You can also contact a librarian or find a research guide.

Policies

Attendance and participation

You are expected to attend every class and take part in discussion. Activities are in-class analysis of articles and current events, done in groups or alone. None of them appear on the schedule, so attending is the only way to complete them.

Late work

Late submissions receive a 10% penalty for each day late, unless we have arranged something in advance.

Make-up exams

Make-up exams are not permitted except under extraordinary circumstances. Treat the exam dates as obligations.

Artificial intelligence

As with the calculator and the personal computer, new technology should be integrated to complement learning rather than replace it. Using AI as a personal tutor is expected and encouraged, with the caveat that the technology has real limits. To protect academic integrity, more weight falls on closed-book exams, in-class participation, and an oral component.

Communication

Reach me through Canvas or email, with the course number in the subject line. I will do my best to respond within 36 to 48 hours. If you miss class, get in touch as soon as you can so we can catch you up.

Illness and accommodations

The CSU Health Network does not provide excuse notes for missed classes, assignments, or tests. If you need accommodations, contact Student Disability Services as early in the semester as possible. I will do my best to be accommodating in an equitable way; life throws unexpected things at all of us.

Academic integrity

Collaboration on problem sets is encouraged, but each student submits their own work. All exam work is independent.

Classroom norms

We listen with the intent to understand other perspectives, ask questions when we have them, and make sure everyone is heard. When debating policies and theories, we address the merits of the argument rather than the qualities of the person making it.
