Microeconomics Leopold S¨ogner Department of Economics and Finance, Institute for Advanced Studies, Stumpergasse 56, A-1060 Vienna, Austria, Tel: +43 (0) 1 59991 182, soegner@ihs.ac.at 1 Course Outline Learning Objectives: • This course covers key concepts of microeconomic theory. The main goal of this course is to provide students with both, a basic understanding and analytical traceability of these concepts. • The main concepts are discussed in detail during the lectures. In addition students have to work through the textbooks and have to solve problems to improve their understanding and to acquire skills to apply these tools to related problems. – Decision Theory: Rationality, Preference primitives and axioms, revealed preference theory, preference representations, expected utility theorem, risk aversion. – Consumer Theory: Walrasian and Hicksian demand, comparative statics, indirect utility, Slutsky equation, duality theory, welfare measures, aggregate demand. – Production: Production sets and returns to scale, production functions, cost minimization, profit maximization. 2 Literature • Andreu Mas-Colell, A., Whinston, M.D., Green, J.R., Microeconomic Theory, Oxford University Press, 1995.
