The effects on inequality from (A) network structure, (B, C) network fluidity, (D) reputation tracking, and (E) punishment institutions.
The figure shows boxplots for each experimental condition and results from the Mann-Whitney tests comparing each treatment condition to the control condition within each experiment (Mann-Whitney U on top and p-value on bottom, with asterisk if p < 0.05). For each experiment, the first bar shown in the figure is the control condition and each test result compares this control condition to the treatment conditions represented by each next bar in order. Explanation of the experimental conditions can be found in Table 1. In addition, for GRUJ10, “fixed*” refers to a second fixed condition played by the same group and for WANG12, “strategic a/b” means that participants can make up to a partner updates in each of b partner-update periods of the game.
