Comparison between dual-role UG experiments and single-role UG experiments. We analyze the data of the last 35 rounds in the treatment and control groups of the dual-role UG experiments and the last 30 rounds in the treatment and control groups of the single-role UG experiments. For each role, there are 318 samples in the dual-role UG experiments and 100 samples in the single-role UG experiments. (a) Mean values of p and q in the dual-role UG treatment groups and single-role UG treatment groups which include 50 proposers and 50 responders. (b) Mean values of p and q in the dual-role UG control groups and single-role UG control groups which include 50 proposers and 50 responders. (c) Proportions of rational behaviours of proposers and responders in the dual-role UG treatment groups and single-role UG treatment groups. (d) Proportions of rational behaviours of proposers and responders in the dual-role UG control groups and single-role UG control groups. Error bars indicate ±1 s.e.m.
