Are Two Heads Better Than One? Team versus Individual Play in Signaling Games
通过信号博弈实验比较个人与两人团队的表现，发现团队在困难博弈中更具策略性并产生正协同效应，尤其在收益变化后表现出更强的学习迁移能力。
We compare individuals with two-person teams in signaling game experiments. Teams consistently play more strategically than individuals and generate positive synergies in more difficult games, beating a demanding “truth-wins” norm. The superior performance of teams is most striking following changes in payoffs that change the equilibrium outcome. Individuals play less strategically following the change in payoffs than inexperienced subjects playing the same game. In contrast, the teams exhibit positive learning transfer, playing more strategically following the change than inexperienced subjects. Dialogues between teammates are used to identify factors promoting strategic play.
