Mechanism Design

Course content

The teaching in this course may be changed to be taught either fully or partly online due to COVID-19. For further information, see the course room on Absalon. The time, place and type of assessment used for the exam may also be changed due to COVID-19, and any further information will be announced under the panel “Exam”.

Mechanism design explores institutions in environments with asymmetric information. While game theory explores how players act in a given environment, mechanism design takes a dual approach and asks instead how we should design the environment to induce the desirable behavior. Real-world applications include, among others, market design, organization of social choice and voting mechanisms, design of regulations and institutional design in general.

 

The course can roughly be split in two parts:

  • Part 1 introduces the students to the classic results and methods of mechanism design. We introduce classical mechanisms and discuss their strengths and weaknesses. We then look at mechanisms that are optimal in some special cases, such as trade, social choice, and matching problems.
  • Part 2 explores the world beyond the models described in the first part. In particular, we look at cases when agents' information is correlated, at mechanism design in dynamic settings, at mechanism design without money, and conclude with information design.

 

The course is based on selected chapters from the textbooks by Börgers, and by Roth and Sotomayor, as well as on recent surveys.

 

Education

MSc programme in Economics – elective course

 

The PhD Programme in Economics at the Department of Economics:

  • The course is an elective course with resarch module. PhD students must contact the study administration and the lecturer in order to write the research assignment.
  • The course is a part of the admission requirements for the 5+3 PhD Programme. Please consult the 5+3 PhD admission requirements.
Learning outcome

After completing the course the student is expected to be able to:

 

Knowledge:

  • Account for the fundamental ideas behind and approaches to mechanism design.
  • Define main trade-offs arising in information extraction problems.
  • Identify the limitations of existing approaches to mechanism design.
  • Explain and discuss key theoretical concepts from academic articles, as well as discuss their interpretation

 

Skills:

  • Set up policy, trade, and management issues as mechanism design problems.
  • Propose mechanisms that induce the desired outcomes in various environments.
  • Analyze the drawbacks of existing institutions and suggest alternatives or identify reasons why none are available.

 

Competencies:

  • Apply the most relevant theoretical apparatus to analyze case-based problems.
  • Use the analytical framework of mechanism design in discussions of the real-world institutions, proposed policies, and market strategies.

 

Mostly lectures covering the syllabus with a view towards accomplishing the course goals. Supplemented by problem sets.

It is strongly recommended to have followed the course Microeconomics III at the study of Economics, University of Copenhagen, prior taking this course.

Mastering the material from the mathematics courses in the Bachelor program (Mathematics A and B) is very helpful.
