September 2014 New York University Matching Theory Mini Course: Primer and Some Recent Development Yeon-Koo Che Matching theory has taken a center stage in market design specifically and economic theory more generally, with successful practical applications in medical matching and school choice. The current course provides a basic introduction into matching theory, discusses “school choice” as an application, and touches upon some frontier topics in matching theory research. Specifically, we will discuss some basic theories of two-sided matching, studying design objectives such as stability, efficiency, and incentives. We will study how these objectives conflict each other in the finite markets such as in the context of school choice, and then study whether and how the conflicts get resolved in the large markets. • General Information: – Class Hours: Monday: 1:00-3:00PM, Sept 8, 15 and 22 – Location: Room 736. – Contact Information: (E-mail) yeonkooche@gmail.com – Office Hours: via email appointment.
