If at least one UTIPE and non-Japanese speaking
student participates in this class, the lecture is

Purposes of This Lecture
(a) To learn basic models for analyzing oligopoly
markets such as Cournot, Bertrand, Stackelberg,
Hotelling, and so on.
~ Welcome the students who are interested in
theoretical (applied) microeconomics such as
Industrial Organization, Regional Science, Contract
Theory, Law and Economics, Labor Economics and
so on, especially who are Doctor course students or
Master course students who are planning to go to
Doctor course, but not limited to those students.

Purposes of This Lecture
(c) To obtain some examples which can be used for
writing more theoretical papers (such as pure game
theory or microeconomic theory), or empirical papers.
(d) To learn real world examples in Japanese
economies~ not suitable. Economics of Regulation
and Law and Economics presented at Graduate
School of Public Policy must be better (but these are
presented in Japanese).

Requirement
(a) Basic knowledge of Microeconomic Theory and
Game Theory is indispensable.
(b) Basic knowledge of Game Theory is indispensable.
~If you do not know basic concepts of game theory
such as `subgame perfect Nash equilibrium’, you
should take this lecture after taking Core Course
Microeconomics.
(c) Very preliminary technique of optimization is
required. If you do not know `first-order condition’
and `second order condition’, you should not take
this lecture.
(d) Basic knowledge of Industrial Organization is not
required.

Reading Assignment
No reading assignment. I do my best to present clear
descriptions of the standard models of oligopoly. I
think that all students who have sufficient knowledge
on graduate level of microeconomics and game
theory can understand the course without reading
any papers before the class.
Reading list exists
(1) for the convenience of the students who are
interested in some specific topics after the class, and
(2) to make sure that what paper I explain in the lecture
(in the slide, only the names of authors and the
publication year appear).

Grading
・No written examination. Grade is based on class
participation.
・I will never provide grade C. In this case, I will
provide D.
・Comments in the class are welcome. Students are
required to attend the class after agreeing that
they are expected to make contributions to the
class and I sometimes ask the participants to
express their own opinions.
・I prepare some quizzes in the class to make sure
that the students understand the lecture.
