Discussion and Fairness in a Laboratory Voting Experiment

We conduct a laboratory experiment to investigate whether public discussion before a majority vote increases the saliency of minority interests and results in more egalitarian outcomes or whether voters use discussion to form majorities that benefit at the expense of minorities. When there are two alternatives, we find that public discussion increases the likelihood that individuals vote for equal allocations, but has little to no impact on the group outcomes. When participants choose among one equal and several unequal options, the multitude of unequal options creates a coordination problem, and we find that discussion decreases the frequency of egalitarian decisions. Our findings suggest that the effect of public communication on the fairness of majority voting outcomes depends on the strategic environment.
