Time and Location (attention: changed from the originally announced ones)

Time: Monday& Thursday, 4:15-6:05 PM

Location: room 130, the Education building.



Syllabus (this syllabus is evolving and will be modified as the class proceeds. See also the University website)

This is a topics course in game theory. A variety of topics will be covered, but an emphasis is on mechanism/market design, such as matching theory and auction theory.

I will put emphasis on recent advances in the topic and present open questions so that interested students can promptly come to the frontier and begin their own research.

I will assign papers to read for each class, and sometimes ask students to present in front of the class.

Grading

Grading will be based on class participation (discussion, student presentations) and one final paper plus a midterm paper (added 12/29/2009).


* The deadline for the midterm is February 18th. I want you to write up either (1) a rough draft of the final or (2) a substantial literature review (updated 01/14/2010).

(1) I want you to encourage you to use the midterm assignment as opportunity to jump-start the final project.

(2) If you choose to do a literature review, please write not only summaries of papers, but also put in your thoughts/perspective (updated 01/14/2010).



* The deadline for the final paper is March 19th. You are welcome to use a paper that you are working on your own or for another class,

as long as it is on the topic of game theory and is appropriate in terms of relevance and quality.

This means that you can even use your work you submitted for my market design class last quarter as long as you make a substantial progress on the previous version.

This is not because I want to give you easy time, but to encourage you to write a paper that is very serious and potentially publishable.

So if you use a paper used for Econ 285, grading may be a bit more strict.


*There are two presentations. One is tentatively scheduled on February 8th or 11th. Each presentation lasts about 20 minutes (including questions and answers)

You can choose either to (1) present your own research for the midterm paper, or (2) choose a paper written by someone else and present it.

For the papers to present, feel free to choose any paper on the reading list below that is not attached the asterisk (*).

If you want to present something that is not on the list, write to me and we will figure out whether the paper is suitable for the class. (updated 01/14/2010).


The other presentation is a presentation on the final paper, tentatively scheduled either on March 4th or 8th or 11th.

Each presentation lasts about 20 minutes (including questions and answers)

Joint projects are welcome. Let me know.


Prerequisite

Game theory at the 1st year PhD level.

Also it is strongly recommended that you have taken Econ 285, because some of the topics are based on the material covered there.

If not, please familiarize yourself with the topic, by taking a look at slides at
