Maximum effort in the minimum-effort game
在哥本哈根进行的标准最小努力博弈实验中，六人组常能协调到帕累托最优均衡，与以往文献结果相反。研究发现，丹麦被试比例越高，最小努力水平越高，表明被试群体效应显著影响协调失败。
Abstract We report results from standard minimum-effort experiments conducted in Copenhagen (Denmark). Our subjects frequently coordinate on the Pareto-efficient equilibrium even in groups of six. This is in stark contrast to the previous literature, as we show in a detailed analysis of experiments which had the same design but were held in different countries. The subject-pool effect is substantiated by the finding that, the higher the share of Danish subjects in a group, the higher the minimum-effort levels. These findings suggest that the prevalent coordination failures previously observed are affected by significant subject-pool effects.
