Games, Economic Behavior, and the Internet

Information Science 6230
Cornell University, Fall 2013

Tues-Thu 10:10-11:25am

There are many settings on the Internet where agents make decisions that involve responding to incentives, trading off costs and benefits, or strategizing about the behavior of other agents. Examples include online auctions (on Ebay, or advertising auctions); voting--- either explicitly, such as ratings on Reddit or implicitly, as in search engine rankings; crowdsourcing contests as in TopCoder or Innocentive; labor markets as in Mechanical Turk or ODesk; peer-to-peer file sharing; social lending platforms, and a vast range of social computing systems.

This course will examine models and theoretical foundations--- such as information elicitation, contest design, auctions, matching markets, public goods games--- that are relevant to economic behavior on the Internet, as well as discuss the design and behavior of actual systems.

The course will consist of a combination of lectures by the instructor, and seminar-style presentation of research papers by students. Assignments of papers to students for presentation will be made in the first few weeks of class.
