The 3rd US-Japan Joint Conference on Mathematical Sociology
Supported by COE21 "Center for the Study of Cultural and Ecological Foundations of the Mind"

Date: June 24 (Friday) - June 26 (Sunday), 2005
Location: Hokkaido University Conference Hall

In the 3rd US-Japan joint conference of Association for Mathematical Sociology (supported by COE21"Center for the Study of Cultural and Ecological Foundations of the Mind"), some principal investigators and graduate students of our team made a presentation of their studies. Rie Mashima and Nobuyuki Takahashi reported a series of studies regarding the mechanism supporting "generalized exchange" in the Session 2. In the poster session, Mizuho Shinada and Toshio Yamagishi reported the effect of the sanction system on the maintenance of cooperation among people.
