Chair of Microeconomics
The Subject
The course Microeconomics deals with economic behaviour and decisions of individuals. Important branches are the theory of the firm and the theory of the household. Furthermore, questions on which results are genrated by competitive processes are analysed and evaluated. In addition, macroeconomic aspects are examined which result from the complex relationships among individuals typical for a capitalistic system.

July 15 2025 - Seminar (M.Sc. Economics) in the winter term 2025/26
We offer a seminar (M.Sc. Economics) on "Innovation and technological progress: Measurement, Prediction, Policy" this winter term. Please see the page of the seminar in OPAL for more details.
Please note: As the projects will almost always involve data analysis or modeling, basic knowledge in programming is mandatory. We would recommend that you have some working knowledge in either R or Python, although other programming languages are also acceptable. Basic knowledge would be attained if you have for example passed any one of the following courses: Computational Economics I or II, Empirical Economics I or II, Introductory Empirical Economics (Grundlagen der Empirischen Wirtschaftsforschung) or the seminar on Agent-Based Modeling. If you have doubts about this point, please get in touch with the lecturers.
Interested students can enroll directly on the page of the seminar in OPAL until Oct 20 2025.
February 21 2025 - New research article about productivity dispersion and firm growth in Canada published
The research article Jangho Yang, Brian Cozzarin and Torsten Heinrich ("Productivity dispersion and firm growth in Canada", Journal of Evolutionary Economics, DOI) was published earlier this month. Using data for Canada, the paper finds some a negative relation of growth and productivity dispersion (NIQR) and inverted U-shape relation for growth and productivity. The two results are connected and have important implications for firm dynamics and economic policy.
Oct 02 2024: GENED 2024 meeting at TU Chemnitz
With 21 contributed talks, almost 40 participants, and an extended tutorial by Jean-Philippe Bouchaud (ENS Paris, CFM, ICL) on "Topics in Complexity Economics", the annual meeting of the GENED (German Network for New Economic Dynamics) took place at TU Chemnitz this week from Sep. 30 to Oct 2.
July 31 2024 - Research article on the distribution of productivity across firms
J. Yang, T. Heinrich, J. Winkler, F. Lafond, P. Koutroumpis and J. D. Farmer ("Measuring productivity dispersion: a parametric approach using the Lévy alpha-stable distribution", Industrial and Corporate Change, DOI) characterize the distribution of productivity among 7 million European firms and find strong evidence for a Lévy alpha-stable distributional model with an infinite second moment, which has implications for the debate about productivity dispersion and misallocation.
