How do measures to increase turnout affect election outcomes? I use a novel approach to analyze how these measures influence both voter turnout and the candidates' political positions. In general, lowering the net expense of voting reduces political polarization. If the net expense of voting is made very low, then candidates no longer have an incentive to take partisan positions to motivate turnout and will converge at the median voter's ideal point. For small changes in the net expense of voting, however, decreasing the cost of voting and penalties for not voting (two common measures) can result in drastically different political outcomes. Counter intuitively, measures that make voting cheaper might not increase turnout: since these measures decrease the difference between the candidates' political positions, they also decrease the benefit of voting.

AbstractThis article explores information aggregation and strategic communication in settings where committee members are held accountable, formally or informally, for their individual voting decisions. We show that if decisions are made via majority voting, expressive payoffs introduce a free‐rider problem that prevents the committee from communicating truthfully and taking optimal decisions. In contrast, if decisions are made by unanimity, free‐riding is mitigated because all agents are responsible for the committee's decision. In a controlled laboratory experiment, we find that under unanimity subjects are more truthful and are ultimately more likely to take the optimal decision.

Despite numerous studies on the social and political impact of refugees in Europe, we have very little systematic evidence on the impact of refugee settlement on social cohesion in the developing world. Using data gathered in Northern Lebanon, we show that increased salience of the "refugee crisis" decreases natives' trust and prosocial preferences toward refugees, suggesting a negative impact of mass refugee settlement. However, this negative impact is driven exclusively by respondents with no individual exposure to refugees. In fact, despite concerns that refugee settlements may result in local conflict, we find that individual proximity to refugees is positively correlated with trust towards refugees, and that proximity has a positive spillover effect on social capital towards other migrants. This implies that, while the refugee crisis may have had a negative impact on social cohesion, this negative impact is mitigated in areas where natives are in contact with refugees.

While scholars and pundits alike have expressed concern regarding the increasingly "tribal" nature of political identities, there has been little analysis of how this social polarization impacts political selection. In this paper, we incorporate social identity into a principal-agent model of political representation and characterize the impact of social polarization on voting behavior. We show that identity has an instrumental impact on voting, as voters anticipate that political representatives' ex post policy decisions have an in-group bias. We also conduct a laboratory experiment to test the main predictions of the theory. In contrast to existing work that suggests social polarization may have a positive impact by increasing participation, we show that social polarization causes political representatives to take policy decisions that diverge from the social optimum, and voters to select candidates with lower average quality.
