This course approaches microeconomic analysis at an advanced level, presenting some formal techniques used in economic analysis as well as critical perspectives and possible alternatives. Topics may vary from year to year and include elements of choice and decision theory, theory of the consumer and the firm, game theory, welfare economics, social choice and aggregation, and general equilibrium theory. Adequate mathematical background, including thorough prior familiarity with multivariate analysis and constrained optimization, linear algebra and matrix operations, and methods of abstract notation, reasoning and proof making, is assumed. Knowledge of elementary set theory and real analysis would be helpful. Lab sessions will be arranged. Prerequisite: GECO 6190 or permission of the instructor.
