Evolution of fairness on social networks
MICA Auditorium at the Department of Biology (1st floor), 12h - 13h quinta-feira, 12-10-2017
Experiments on the Ultimatum Game (UG) have shown time and again that people’s behavior is a far cry from what a rational person would do. Several theoretical works have proposed that these results may arise evolutionarily when subjects act in both roles and there is a structure in the population specifying who plays with whom. In this seminar, Boyu Zhang introduces two networked UG experiments to test the above ideas. In experiment in which subjects play a single role, social networks promote the emergence of communities and diversity but do not affect the average fairness level. In experiment in which subjects play simultaneously both roles, acceptance levels of responders approach rationality, while proposers accommodate their offers to their environment.

Furthermore, he will show that proposers follow a best-response-like approach to choose their offers, but subjects keep their acceptance levels all the time.

Dr. Boyu Zhang is an associate professor at School of Mathematical Sciences, Beijing Normal University. His research interests mainly focus on evolutionary game and behavior economics.

His work has been published in journals including Proceedings of the National Academy of Sciences, Games and Economic Behavior and Experimental Economics.

All interested are welcome and we are counting on your presence.
