Content

The goal of the course is to familiarize students with economic theory that underlies competition-policy practice. The students should get a formal and intuitive understanding of basic economic concepts and strategic interactions of firms, consumers and regulatory concepts. To this end, the course discusses many applications in each topic, including actual competition-policy cases from Europe and North America.

Here is a list of the topics we will cover in class:

Teaching methods

The goal of the course is to familiarize students with the economic theory that underlies competition-policy practice. The economic theory will be introduced using economic models. However, the course puts great emphasis on an intuitive understanding of these concepts. To this end, we will frequently discuss applications of the theory and real-life competition-policy cases from Europe and North America.

The course starts in the first week of the first term (Q1). The first lecture will take place in the classroom.

Evaluation methods

The students have to submit a graded homework on which they have to work in groups.

The graded homework and the final written exam consist of three parts.

The type of evaluation (e.g. written- or oral exam) in the third exam session (i.e. for students who do not succeed in the first exam session) will be determined based on the number of enrolled students.

The graded homework and the final written exam consist of three parts.

- Questions on the understanding of basic economic concepts that were discussed in class.
- Questions on a theoretical model.
- Case-study questions where the students have to apply the economic concepts that we discussed in class to discuss a real-life economic problem. This can be, for example, aspects of a real-life competition-policy case.
