Microeconomics
Graduate Institute of International and Development Studies
EI037 - Fall 2023 - Course- 6 ECTS
Thursday 10:15-12:00
Lecturer: Yuan Zi
Office hours: Wednesday 10:15-12:00 (class weeks)
Course Description
This course is an introduction to the concepts and tools of Microeconomic analysis. We will start with classic topics of consumer choice, and then firm decisions about optimal production and the impact of different market structures on firms' behavior. Next, we turn our attention to supply and demand, and the basic forces that determine an equilibrium in a market economy. The final section of the course introduces some of the more advanced topics that can be analyzed using Microeconomic theory. Students should be comfortable with basic multivariable calculus, linear algebra, and real analysis.
Goals
After the course, you should have developed a range of skills enabling them to understand economic concepts and use those concepts to analyze specific questions.
By the end of this course, you should be able to:
Main textbooks
Additional textbooks
NB: It is sufficient to understand what covers in the course, which mainly follows MMG but simplifies it. Students are encouraged to use the listed textbooks and references to enhance their understanding of course materials when needed.
We all have different backgrounds and prefer different learning styles. Student are encouraged to use google or the library for fragmented learning materials when a question arises. Don’t read a whole textbook when you are confused about one particular thing - it is usually not very helpful and surely not efficient!
Undergraduate-level microeconomics, basic multivariable calculus, linear algebra, and real analysis. Math course ("bootcamp") in the Graduate Institute for students in MA Economics.
Grading
There will be a midterm exam (1/3 of the final grade), and a final exam (1/3 of the final grade), as well as 2 problem sets (2 × 1/6 of the final grade).
Outline (preliminary)
Mathematics Tool Box recommended by previous lecturers
Students who do not feel comfortable with calculus and standard mathematical tools for economists are strongly advised to either take the math course (choose it as part of the mandatory sequence or sit-in) or consult and work with Martin Osborne’s tutorial site (the strong point of this tutorial is that it provides exercises with solutions and thus students can practice on their own).

- Understand firm behavior.
- Analyze different types of market structures.
- Understand basic aspects of general equilibrium.
- Understand basic aspects of welfare economics.
- Understand how to apply economic principles to a range of policy questions.
