This course covers the elementary topics in non-cooperative game theory. These topics include (1) games in strategic form, dominated strategies, Nash equilibrium; (2) games in extensive form and subgame-perfect equilibrium; (3) repeated games and the Folk Theorem; and (4) evolutionary game theory.
In everyday life, people interact with each other. Game theory is a mathematical tool used in analyzing the interaction among rational decision makers. Its applications range throughout many topics in economics and management, and by applying this theory, additional insights may emerge. The objective of this course is for students to be able to apply the theory when examining topics of their interest in economics and industrial engineering.
By taking this course, students will have attained the following skills:
1) Build an economic model using non-cooperative game theory.
2) Calculate Nash equilibria, subgame-perfect equilibria, etc. of games given in strategic form and extensive form.
3) Think logically and explain social phenomenon using game theory.
