Power illusion in coalitional bargaining: An experimental analysis
实验检验了Baron-Ferejohn模型,发现名义权力差异的初始影响随经验减小或消失,环境复杂性会减缓这一转变,而暂停休息能加速学习。
One feature of legislative bargaining in naturally occurring settings is that the distribution of seats or voting weights often does not accurately reflect bargaining power. Game-theoretic predictions about payoffs and coalition formation are insensitive to nominal differences in vote distributions and instead only depend on pivotality. We conduct an experimental test of the classical Baron-Ferejohn model with five-player groups. Holding real power constant, we compare treatments with differences in nominal power. We find that initial effects of nominal differences become small or disappear with experience. Our results also point to the complexity of the environment as having a negative impact on the speed at which this transition takes place. Finally, and of particular importance as a methodological observation, giving subjects a pause accelerates learning.
