Materials Visit http:// dbs.iss.u-tokyo.ac.jp/~matsumur/OT2016.html You need not remember this address because you will reach if you follow the links of my HP. You can obtain the files of reading list, slides presented in this class, and so on. I will upload files I will use in the class by the end of previous week (Saturday night) ~ so you can see the file before the class. Oligopoly Theory

Purposes of This Lecture To learn basic models (the models that will be standard even in distant future) 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. Oligopoly Theory

Purposes of This Lecture To obtain some ideas for writing academic papers of Industrial Organization, Regional Science, and so on.

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). Oligopoly Theory

Requirement Basic knowledge of Microeconomic Theory is indispensable. Basic knowledge of Game Theory is also indispensable. ~ This course is for the students who took or now take Core Course Microeconomics at Graduate School of Economics. (b) Preliminary technique of optimization is required. If you do not know `first-order condition’ and `second-order condition’, you should not take this lecture. (c) Basic knowledge of Industrial Organization is not required. Oligopoly Theory

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.
