Communication Among Voters Benefits the Majority Party
通过实验室实验，研究选民在投票前进行沟通如何影响投票率，发现沟通能提高多数党的投票率优势，从而增加其获胜概率。
How does communication among voters affect turnout? In a laboratory experiment, subjects, divided into two competing parties, choose between costly voting and abstaining. Pre-play communication treatments, relative to the no communication control, are public communication (subjects exchange public messages through computers) and party communication (messages are public within one's own party). Communication benefits the majority party by increasing its turnout margin, hence its winning probability. Party communication increases turnout; public communication decreases total turnout with a low voting cost. With communication, there is no support for Nash equilibrium and limited consistency with correlated equilibrium.
