Course description and aims

 This course will provide a comprehensive overview of theoretical microeconomic analyses at the undergraduate level. In every textbook on introductory economics or civics studied in junior high schools, there are figures illustrating a downward-sloping "demand curve" showing that "the demand increases as the price decreases", an upward-sloping "supply curve" demonstrating that "the supply increases as the price increases", and a "market equilibrium" at which the demand and supply curves intersect. However, demand curves illustrate the results of consumption choices, and it is not obvious what kinds of consumers' behavior lead to a downward-sloping demand curve. Similarly, supply curves demonstrate results of firms' production activities, and it is not straightforward what kinds of firms' behavior lead to a upward-sloping supply curve. In this course, we analyze economic activities behind the demand and supply curves and then examine the properties of market equilibria to clarify why market transactions with prices are effective and widely used.
Microeconomics is important for understanding economic phenomena, and it is essential for the studies of economics, industrial engineering, and other related fields. By combining lectures and exercises, the course aims to enable students to understand the basic ideas in microeconomics and acquire the fundamentals of microeconomic analytical tools widely applicable to various economic and management situations. Analytical tools taught in this course are not only useful in studying market mechanisms, but are applicable to various other types of economic systems, and are useful in other courses on economics and industrial engineering.

Student learning outcomes

At the end of this course, students will be able to:
1) Explain the properties of preferences and indifference curves of consumers
2) Analyze the utility maximization problem.
3) Explain the income effect, the substitution effect, and law of demand
4) Analyze the profit maximization problem and cost minimization problem.
5) Derive the cost function and the supply function.
6) Compare perfect competition and monopoly in terms of consumer surplus, producer surplus, and social surplus.

Keywords

Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
