Date:January 27, 2011 (Thursday) 10:00~12:00

Location: Hokkaido University, Faculty of Letters, room E204

Participants: Taiki Takahashi, Nobuyuki Takahashi, Syunya Matsushima, Satomi Higuchi, and others (total 24 participants)

We examined whether voting behavior is analog or desital, and the information cascade is phase transition or not, by a voting experiment. Results show that voting behavior depended on the reference number of past voting results.
