Course Description: A mathematically rigorous investigation of the interplay of economic theory and computer science with an emphasis on the relationship of incentive compatibility and algorithmic efficiency. Particular attention is paid to the formulation and solution of mechanism-design problems that are relevant to data networking and Internet-based commerce. Suitable for mathematically inclined advanced undergraduates and first- or second-year graduate students in Computer Science, Economics, or closely related fields. Some familiarity with basic computational theory and basic microeconomic theory is helpful but not a formal prerequisite. The course both satisfies the QR requirement and counts as a CS-major elective.
Instructors: Dirk Bergemann and Joan Feigenbaum
Note: Professor Feigenbaum suffers from repetitive-strain injury and cannot handle large amounts of email. Students should not send her email about this course but rather should contact her through the TA, through her assistant (Judi.Paige@yale.edu, x6-1267), during class, or during her office hour.

Solutions for Homework 5
Exam 1 in ECON 425/563 // CPSC 455/555 will be given in class on Oct 16, 2008.
It will cover five basic topics:
- Different types of equilibria or solution concepts
- Finding solutions (in the sense of 1 above) of specific games
- Combinatorial auctions
- The Internet as an economy, as exemplified by interdomain routing
- Games on graphs (routing games and graph-formation games)
This material is covered in
- AGT Chapters 1, 9, 11.1, 11.2, 11.3, 11.7, 14.1, 14.3, 18.1, 18.2, 18.3, 18.4, 19.1, and 19.2
- Notes and slides from September 9, September 11, September 16, September 25, and September 30, and
- Homework assignments 1 and 2.
Exam 2 in ECON 425/563 // CPSC 455/555 will be held in class on December 4, 2008 and will cover the following topics:
- Sponsored search auctions
- Recommender systems and collaborative filtering
- Reputation and trust
- Information markets
To study for this exam, you should review:
- Lecture notes and slides for October 23, 2008 through November 20, 2008
- Homework assignments 3 and 5
- The survey articles by Resnick et al. mentioned in homework assignment 5a
- Sections 26.1, 26.2, 26.5, 27.1, 27.2, 27.3, 28.1, 28.2, and 28.3 of AGT
- Practice Questions for Information Markets [Solutions]
These questions about information markets should be useful in studying for Exam 2. This is just a study aid, not an assignment; you need not hand it in and won’t be graded on it.
