MA Economics of Information and Internet

Description:

This unit deals with the economics of the production and distribution of information goods on the Internet. We will analyse the production, pricing and distribution of products that are mainly informational in nature such as software and news. We will also study the structure and functioning of Internet-mediated markets as well as of models of production that are specific to the Internet.

Lectures (2 hrs/week):

  1. Information goods: pricing, bundling, versioning, sampling, reputation.
  2. Models of consumer search for goods and information online.
  3. Intermediation, network effects and platform competition.
  4. Open source software and the collaborative production of information goods.

Exercises (2 hrs/week):

Exercises will focus on analysing specific aspects of the strategies of a range of Internet companies, as explained in recent published academic articles. Each student will be required to prepare one short 20 mn presentation of one article from the reading list. We will also solve a few formal models for concepts dealt with in the course.
