Voice and Political Engagement: Evidence From a Field Experiment
We conduct a natural field experiment with a major European party to test whether giving party supporters more voice increases their engagement in the party’s electoral campaign. In the experiment, the party asked a random subset of supporters for their opinions on the importance of different policy areas. Giving supporters opportunities to voice their opinions increases their engagement in the campaign as measured using behavioral data from the …
Does Rent Control Turn Tenants Into Nimbys
Political Activists are Not Driven by Instrumental Motives: Evidence from Two Natural Field Experiments
Are political activists driven by instrumental motives such as making a career in politics or mobilizing voters? We implement two natural field experiments in which party activists are randomly informed that canvassing is i) effective at mobilizing voters, or ii) effective for enhancing activists’ political careers. We find no effect of the treatments on activists’ intended and actual canvassing behaviour. The null finding holds despite a success…
Government Spending and Voting Behavior
Does government spending on public goods affect the vote choice of citizens? On one hand, prior research has characterized voters as fiscal conservatives who may turn toward conservative parties when government spending goes up. On the other hand, increased spending may signal that the economy is doing well, which makes progressive parties a more viable option. To adjudicate between both hypotheses, this article draws on a natural experiment, whi…
Refugee Labor Market Access Increases Support for Immigration
Does the economic integration of refugees affect public attitudes toward migration? We assess this pertinent question by examining a policy change in Germany, where the government significantly eased labor market access for refugees in the majority of the country. Using administrative employment data, we show that the policy led to a substantial increase in refugee employment, while natives’ wages and employment rates remained unaffected. The pol…
Political Activists as Free Riders: Evidence from a Natural Field Experiment
How does a citizen’s decision to participate in political activism depend on the participation of others? We conduct a nationwide natural field experiment in collaboration with a major European party during a recent national election. In a party survey, we randomly provide canvassers with true information about the canvassing intentions of their peers. When learning that more peers participate in canvassing than previously believed, canvassers si…
Can religious norms reduce violent attitudes? Experimental evidence from a Muslim–Christian conflict
We study whether religious anti-violence norms can reduce violent attitudes in settings of deep religious divisions. Our study context is a neighborhood in Nairobi with a history of religious violence. We randomly expose 576 Christian and Muslim respondents to anti-violence norms drawn from religious sources and find that the primes reduce violent attitudes by 0.2 standard deviations. We find no evidence, however, that highlighting the norms’ rel…
The Long Shadow of Slavery: The Persistence of Slave Owners in Southern Lawmaking
This paper documents the persistence of Southern slave owners in political power after the American Civil War. Using data from Texas, we show that former slave owners made up more than half of all state legislators until the late 1890s. Legislators with slave-owning backgrounds were more likely to be Democrats and voted more conservatively even conditional on party membership. A county's propensity to elect former slave owners was positively corr…
Group Size and Protest Mobilization across Movements and Countermovements
Many social movements face fierce resistance in the form of a countermovement. Therefore, when deciding to become politically active, a movement supporter has to consider both her own movement's activity and that of the opponent. This paper studies the decision of a movement supporter to attend a protest when faced with a counterprotest. We implement two field experiments among supporters of a right- and left-leaning movement ahead of two protest…
Does State Repression Spark Protests? Evidence from Secret Police Surveillance in Communist Poland
Does physical surveillance hinder or foster antiregime resistance? A common view holds that surveillance prevents resistance by providing regimes with high-quality intelligence on dissident networks and by instilling fear in citizens. We contrast this view using formerly classified data from Communist Poland. We find that communities exposed to secret police officers were more likely to organize protests but also engaged in less sabotage. To ensu…
Protestant Missionaries Are Associated With Reduced Community Cohesion
Do Protestant missionaries affect community cohesion? This study puts forth two mechanisms that link missionaries to trusting, cooperative community life: pro-social preferences and social networks. On the one hand, Protestant missionaries espouse charity, and they establish regular venues of social interaction. On the other hand, Protestant missionaries propagate an individualist faith, and they provide an identity along which communities may se…
What Drives Migration to Europe? Survey Experimental Evidence from Lebanon
What drives people to migrate? Amid a stark increase in international migration at the global scale, we lack individual-level evidence that causally adjudicates between migration’s many drivers. We implement a survey experiment in Northern Lebanon—a hotbed of international migration—to a random sample of 1,000 Syrian refugees and 1,000 Lebanese residents. Respondents were shown the profile of a hypothetical Syrian refugee and asked whether they r…
Does Party Competition Affect Political Activism
Does party competition affect political activism? This paper studies the decision of party supporters to join political campaigns. We present a framework that incorporates supporters’ instrumental and expressive motives and illustrates that party competition can either increase or decrease party activism. To distinguish between these competing predictions, we implemented a field experiment with a European party during a national election. In a se…
Does Public Opinion Affect Political Speech
Does public opinion affect political speech? Of particular interest is whether public opinion affects (i) what topics politicians address and (ii) what positions they endorse. We present evidence from Germany where the government was recently forced to declassify its public opinion research, allowing us to link the content of the research to subsequent speeches. Our causal identification strategy exploits the exogenous timing of the research's di…
Attitudes Toward Asylum Seekers: Evidence from Germany
What theories explain variation in public opinion toward asylum seekers? We implement a survey experiment in which a representative sample of German residents evaluates vignettes of asylum seekers, which randomly vary attributes that speak to deservingness, economic and religious threat, and gender considerations of attitude formation. We find strong support for deservingness theories. Economic and religious threat theories also receive empirical…
Do Online Ads Influence Vote Choice
Do online ads influence vote choice? We partner with a German party to evaluate the effectiveness of online ads using a cluster-randomized experiment. During the 2016 Berlin state election, 189 postal districts were randomly assigned to (a) emotional ads; (b) factual ads; or (c) no ads. Analyzing electoral results at the postal district level, we find that the overall campaign weakly increased the party’s vote share by 0.7 percentage points (p-va…
Do Inheritance Customs Affect Political and Social Inequality
Why are some societies more unequal than others? The French revolutionaries believed unequal inheritances among siblings to be responsible for the strict hierarchies of the ancien régime. To achieve equality, the revolutionaries therefore enforced equal inheritance rights. Their goal was to empower women and to disenfranchise the noble class. But do equal inheritances succeed in leveling the societal playing field? We study Germany—a country with…
Ethnic Riots and Prosocial Behavior: Evidence from Kyrgyzstan
Do ethnic riots affect prosocial behavior? A common view among scholars of ethnic violence is that riots increase cooperation within the warring groups, while cooperation across groups is reduced. We revisit this hypothesis by studying the aftermath of the 2010 Osh riot in Kyrgyzstan, which saw Kyrgyz from outside the city kill over 400 Uzbeks. We implement a representative survey, which includes unobtrusive experimental measures of prosocial beh…
