Learning Outcomes (valid 01.08.2018-31.07.2020):
Topics in Economic Theory and Policy: Economics of Strategy for Online and Digital Markets
At the end of the course the student has learned how economics can be used to understand and analyze firm decisions and strategies in modern market places, such as online and digital markets. A key objective is to provide an introduction to applications of game theory and mechanism design by connecting these tools to practical applications.
Content (valid 01.08.2018-31.07.2020):
Economic approch for analyzing strategic interactions between firms, basic workhorse models of competition, introduction to auction theory, and preliminaries of network effects and platform economics. Practical applications are used to illustrate how digital and online markets are different, what economic theories are behind successful online platforms and where policy interventions might be required.
Details on the course content (applies in this implementation):
Most valuable firms in the world are platforms that operate online and offer digital market channels. This course introduces the students to the economic analysis of platform design, pricing, and policy.
The course is divided into two parts. As an introduction to the first part, we review the economic approach to analyzing firm strategies, and go through the basic workhorse models of competition. We use these tools to understand what has made online and digital marketplaces so successful. The key concepts are preferences and data on it (what people want to do) and efficiency of using the data (how to achieve what people want to do). Particular attention is on auctions, a popular method for selling advertisements and goods in online markets.
The second part of the course covers the economics of platforms that serve two sides of a market (for example consumers and advertisers). A requisite to understanding how such a platform can be successful is the analysis of the network effects that additional participants bring to the platform. We study the two most important strategies that a platform firm chooses: pricing and openness, and introduce the models of platform competition. We conclude by an overview of the policy and regulatory issues, such as the role of privacy, the market power of platform giants, and discrimination and other externalities.
Assessment Methods and Criteria (valid 01.08.2018-31.07.2020):
Elaboration of the evaluation criteria and methods, and acquainting students with the evaluation (applies in this implementation):
A passed grade from the exam is required for passing the course.
Workload (valid 01.08.2018-31.07.2020):
Contact teaching 30h
Independent work 127h
Exam 3h presence
Total 160h (6 ECTS)
Details on calculating the workload (applies in this implementation):
Independent work consists of reading the articles given as reading the lecture notes, reading the assigned papers, completing the exercises, and preparing for the exam.
Study Material (valid 01.08.2018-31.07.2020):
Reading material assigned during the course.
Details on the course materials (applies in this implementation):
Each lecture will be backed up by a reading material assigned during the course as there is no fitting current textbook. The course uses several real-world examples to illustrate the underlying concepts, and we will have a guest lecture. Assignments (both reading the reading materials and exercises) are an integral part of passing the course.
However, any microeconomics textbook should be helpful throughout the course; for example, Hal Varian, “Intermediate Microeconomics: A Modern Approach” (Eighth Edition or higher), is not a bad choice. Purchase of such book for this course is not mandatory; the material listed here and given at the lectures is more than sufficient as well.
The numbering in the schedule refers to free ebook “The Economy” by the CORE initiative, which makes a good read otherwise as well, see https://www.core-econ.org.

Prerequisites (valid 01.08.2018-31.07.2020):
The course makes use of game theory and mechanism design, but no prior knowledge of either is required. Courses 31C00100 Intermediate Microeconomics and 30C01100 Mathematical Methods for Economists or equivalent would constitute a useful background knowledge.
Grading Scale (valid 01.08.2018-31.07.2020):
