  • Business models in platform industries

    Spring term 2009

    Method (hours per week): 2 hrs, block seminar

    Course language:  English

    Prerequisites:  Microeconomics course sequence in business or economics

    Examination: oral presentation+slides, seminar paper

    ECTS-Credits: 4 ECTS



    Organizational meeting: Thursday, 4 December 2008, 10:15 -13:30 h, at P 044, L 7, 3–5.

    The seminar will take place on 13 March and 14 March (from 10:00 until 20:00 each day).

    Registration: Registration prior to the start of the seminar is required. Interested students have to register at the secretary, Ms. Mamaç, Verfügungs­gebäude L7, 3rd floor. The maximum number of students is 20.

    Course description: In this seminar we analyze business models of software and internet platforms. To this end we focus on five industries/firms, e.g.: handheld devices, B2B platforms, Amazon MarketPlace, online contacting sites, scout24, online radio. Some reading material is provided; additional research by students is required and central for the success of the seminar.

    Overview: The design of markets and the functioning of business models in software platform markets will be analyzed in selected industries or firms. As background reading one may want to consult the book “Invisible Engines” by David Evans, Andrei Hagiu and Richard Schmalensee, published by MIT Press, which can be downloaded for free after registration at the MIT Press web site. An important role to understand software and internet platforms is the theory of two-sided markets, which is elaborated informally in the above mentioned book and in additional reading material listed below.

    Students will present their work during two full days. Most reading material and presentations are non-formal. Students are expected to make themselves familiar with the economics of platforms and to find information on the selected industries by their own research. This seminar is suited for students of business administration and economics. To register for this course students must have completed 2 years of undergraduate studies.

    The course is

    • part of the diploma course sequence under the same title
    • part of the elective in business studies entitled “Information and Competition”
    • an elective to second year doctoral students



    Diploma students: Microeconomics I – III or equivalent, M&S I or equivalent

    Doctoral Students: Microeconomics I – II or equivalent, M&S I or equivalent



    The grade for the course is based on active participation in class (50%) and the presentation of solutions to the case problems presented below, in form of four team papers (50 %).



    The course sequence consists of three blocks. M&S I, a four hour lecture course (plus 2 hr. Lab) held in the Fall Semester; Seminar on M&S I, a block seminar held at the beginning of the Spring Semester; and the present interactive four+two hour case study course held in the Spring Semester. Participation in both the seminar and the case study course necessitates participation in the Fall Semester course (or equivalent). Participation in the seminar is recommended, but not required for participation in the Spring Semester course.

    The philosophy that has led to the course sequence is as follows: The analysis of a real life strategic planning problem necessitates the reduction of the problem to its essentials. The Fall Semester course is designed to equip the student with the tools relevant for the analysis of such strategic problems at the level of the firm, as well as the level of an industry. Depending on the industry structure, both are prerequisites for the analysis of regulatory and competition policy.

    Emphasis is placed not only on the capability to read the literature on existing models, but also on the generation of new ones that are appropriate for the analysis of specific real life problems. In contrast to the presentation of recipes, the Fall Semester course is designed to equip the student with micro theoretic and game theoretic tools to attack strategic problems.

    In the present Case Study course the student is challenged with the development of new modelling approaches. Towards this, we present a sequence of four cases from different industries. We will form teams of students. The teams will compete against each other in developing answers to two strategic questions raised at the end of each case presentation. The first question will involve a decision problem for a key industrialist in the relevant industry; and the second one a regulatory or competition policy decision problem for that industry. There will be coaching sessions for each case in which the instructors will advise the teams towards the development of constructive models towards these answers.

There will be regular coaching sessions in which the instructors will advise the teams towards the development of constructive models towards these answers.

    Students are allocated to teams randomly for cases 1+2, and again for cases 3+4. Coaching sessions may be held outside the scheduled hours. Konrad Stahl will be in charge of Cases 1 and 2, Martin Peitz of Cases 3 and 4. The course will be held in English language.



    The main reference texts for the course will be

    • Belleflamme, P. and M. Peitz (2009): Industrial Organization: Markets and Strategies, Cambridge, UK: Cambridge University Press, forthcoming (available as draft pdf-file)
    • Tirole, J. (1989): The Theory of Industrial Organization, Cambridge, MA: MIT Press


    We will assign additional material especially to doctoral students.
