Title: Is the information cascade phase transition?

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)

Content:
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.
