This course will provide an introduction to intermediate microeconomic theories, which is an extension of the basic microeconomics. Main topics include consumers’ theory, producers’ theory, perfect competition, imperfect competition ＆ basic game theory, general equilibrium and asymmetric information. During the classes, we will study methods to analyze microeconomic models from static analysis to comparative static analysis, perfect competition analysis to imperfect competition analysis, general equilibrium analysis to Nash equilibrium analysis. We will also demonstrate the principles of the microeconomic theories and their recent developments using quantitative approaches.
