We experimentally investigate information aggregation through majority voting when some voters are biased. In such situations, majority voting can have a "dark side", that is, result in groups making choices inferior to those made by individuals acting alone. In line with theoretical...

We use laboratory experiments to test for one of the foundations of the rational voter paradigm - that voters respond to probabilities of being pivotal. We exploit a setup that entails stark theoretical effects of information concerning the preference distribution (as revealed through polls) on...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

We experimentally study the disincentive effect of taxing work and redistributing tax revenues when redistribution is imposed vs. democratically chosen in a vote. We find a “dividend of democracy” in the sense that the disincentive effect is substantially smaller when redistribution is...

We show theoretical and experimental results that demonstrate the potential of transparency to influence committee decision making and deliberation. We present a model in which committee members have career concerns and unanimity is needed to change the status quo. We study three scenarios -...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic-, joint payoff-maximizing- and cognitively heterogeneous agents. These predict varying degrees...

We theoretically and experimentally study voter behavior in a setting characterized by plurality rule and mandatory voting, where voters choose from three options. We are interested in the occurrence of strategic voting in an environment where Condorcet cycles may occur. In particular, we focus...

We experimentally study behavior in a simple voting game where players have private information about their preferences. With random matching, subjects overwhelmingly follow the dominant strategy to exaggerate their preferences, which leads to inefficiency. We analyze an exogenous linking...
