Abstract 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 dissemination to cabinet members within a window of a few days. We find that exposure to public opinion research leads politicians to markedly change their speech. First, we show that linguistic similarity between political speech and public opinion research increases significantly after reports are passed on to the cabinet, suggesting that politicians change the topics they address. Second, we demonstrate that exposure to public opinion research alters politicians' substantive positions in the direction of majority opinion.
Does State Repression Spark Protests? Evidence from Secret Police Surveillance in Communist Poland
2021American Political Science Review · 63 Zitationen · DOI
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 ensure that the relationship is causal, we use an instrumental variable strategy, which exploits the exogenous assignment of Catholic “spy priests” to local communities. To trace the underlying mechanisms, we draw on qualitative interviews and archival sources. We document that Poland’s comprehensive use of surveillance created widespread anger as well as an incentive for citizens to reveal their true loyalties, thus facilitating antiregime collective action. Once on the streets, protesters refrained from sabotage to signal their political motivation to bystanders and authorities alike.

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 behavior. Our causal identification strategy exploits variation in the distance of neighborhoods to armored military vehicles, which were instrumental in orchestrating the riot. We find that victimized neighborhoods show substantially lower levels of prosocial behavior. Importantly, we demonstrate that the reduction is similarly stark both within and across groups. Using qualitative interviews, we parse out two mechanisms that help explain the surprising reduction in ingroup prosociality: Victimized Uzbeks felt abandoned by their coethnics, and variation in victimization created a feeling of suspicion.

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–counterprotest interactions in Germany. Supporters were exposed to low or high official estimates about their own and the opposing group’s turnout. We find that the size of the opposing group has no effect on supporters’ protest intentions. However, as the own protest gets larger, supporters of the right-leaning movement become less while supporters of the left-leaning movement become more willing to protest. We argue that the difference is best explained by stronger social motives on the political left.

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-value = 0.155). We also estimate a negative effect of the campaign on the vote share of the party’s main competitors of 1.4 percentage points (p-value = 0.094). Turning to the mechanism of persuasion, we find that the factual ads, if anything, fared slightly better than the emotional ads. Our evidence thus provides tentative support that online ads positively affect vote choice.

Abstract 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 support. Gender plays a negligible role. Importantly, we also document that economic and—to a lesser extent—religious threat considerations only matter when respondents evaluate economic refugees. By contrast, political refugees are welcomed nearly unconditionally. Our paper thus replicates key findings from Bansak, Hainmueller, and Hangartner (2016) and Czymara and Schmidt-Catran (2016) using a representative sample and points to an important interaction effect in public opinion formation toward asylum seekers: economic threat only gets activated when refugees’ deservingness is in doubt.

Abstract 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 pronounced local‐level variation in inheritance customs—and find that municipalities that historically equally apportioned wealth, to this day, elect more women into political councils and have fewer aristocrats in the social elite. Using historic data, we point to two mechanisms: wealth equality and pro‐egalitarian preferences. In a final step, we also show that, counterintuitively, equitable inheritance customs positively predict income inequality. We interpret this finding to mean that equitable inheritances level the playing field by rewarding talent, not status.

Does the return of large carnivores affect voting behavior? We study this question through the lens of wolf attacks on livestock. Sustained environmental conservation has allowed the wolf (<i>Canis lupus)</i> to make an impressive and unforeseen comeback across Central Europe in recent years. While lauded by conservationists, local residents often see the wolf as a threat to economic livelihoods, particularly those of farmers. As populists appear to exploit such sentiments, the wolf's reemergence is a plausible source for far-right voting behavior. To test this hypothesis, we collect fine-grained spatial data on wolf attacks and construct a municipality-level panel in Germany. Using difference-in-differences models, we find that wolf attacks are accompanied by a significant rise in far-right voting behavior, while the Green party, if anything, suffers electoral losses. We buttress this finding using local-level survey data, which confirms a link between wolf attacks and negative sentiment toward environmental protection. To explore potential mechanisms, we analyze Twitter posts, election manifestos, and Facebook ads to show that far-right politicians frame the wolf as a threat to economic livelihoods.

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 recommended that the refugee migrate to the European Union. The vignette randomly primed five prominent causes of migration, including push factors (political instability and poverty) and pull factors (open borders, employment opportunities, and cultural openness). We find that pull factors outweighed push factors, suggesting that migrants carefully weigh their chances in Europe. Still, all five primes yielded positive effect sizes, which underlines that prominent theories of migration are complements, not substitutes. Taken together, the evidence suggests that empirical models of migration can be improved if they take into consideration both pull and push factors, rather than prioritizing one over the other.

Abstract 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 significantly reduce both their canvassing intentions and behaviour. An additional survey among party supporters underscores the importance of free-riding motives and reveals that there is strong heterogeneity in motives underlying supporters’ behavioural responses.

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 correlated with cotton production, but negatively with Reconstruction-era progress of blacks. Counties that elected more slave owners also displayed worse educational outcomes for blacks in the early twentieth century.

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 seemingly unrelated party survey, we randomly assigned 1,417 party supporters to true information that the canvassing activity of the main competitor party was exceptionally high. Using unobtrusive, real-time data on party supporters’ canvassing behavior, we find that respondents exposed to the high-competition treatment are 30% less likely to go canvassing. To investigate the causal mechanism, we leverage additional survey evidence collected two months after the campaign. Consistent with affective accounts of political activism, we show that increased competition lowered party supporters’ political self-efficacy, which plausibly led them to remain inactive.
Can religious norms reduce violent attitudes? Experimental evidence from a Muslim–Christian conflict
2022Conflict Management and Peace Science · 7 Zitationen · DOI
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’ religious source increases their effectiveness. Rather, we show that subjects apply the norms in a literal manner, suggesting that it is the norms’ content that make them effective.

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 policy also had a positive effect on natives’ attitudes toward migration. Voters exposed to more refugees in the labor market were two percentage points more likely to vote for pro-migration parties across both state and federal elections. Additional survey analyses suggest that our results are driven by positive native–refugee interactions in the workplace.

Does online fundraising increase charitable giving? Using the Facebook advertising tool, we implemented a natural field experiment across Germany, randomly assigning almost 8,000 postal codes to Save the Children fundraising videos or to a pure control. We studied changes in the donation revenue and frequency for Save the Children and other charities by postal code. Our geo-randomized design circumvented many difficulties inherent in studies based on click-through data, especially substitution and measurement issues. We found that (i) video fundraising increased donation revenue and frequency to Save the Children during the campaign and in the subsequent five weeks, that (ii) the campaign was profitable for the fundraiser, and that (iii) the effects were similar independent of video content and impression assignment strategy. However, we also found some crowding out of donations to other similar charities or projects. Finally, we demonstrated that click data may be an inappropriate proxy for donations and recommend that managers use careful experimental designs that can plausibly evaluate the effects of advertising on relevant outcomes. This paper was accepted by Yan Chen, behavioral economics and decision analysis. Funding: M.

Abstract 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 party’s smartphone application. Survey data reveals that giving voice also increases other margins of campaign effort as well as perceived voice. Our evidence highlights the importance of voice for increasing political engagement.

Peter Schlechtriem is one of the leading scholars in the fields of uniform law, comparative law and the law of obligations. It is therefore not surprising that a large number of authors contributed to this Festschrift on his 70th birthday. On comparative law in particular, prominent experts from twelve countries, among which are the U.S.A, New Zealand, Japan and parts of Europe, deal with fundamental legal issues which will have to be addressed in the 21st century.

Affordable housing is a key challenge of the 21st century. A pivotal driver of growing housing prices is residents' opposition to construction, a phenomenon known as NIMBYism ("Not In My Backyard"). To make housing more affordable, city governments are increasingly implementing rent control policies. Does rent control---by making tenants more likely to stay in their apartments---spark NIMBYism and thus exacerbate the housing crisis? We study the case of Berlin, which recently passed a sweeping rent control law. Leveraging two discontinuities in the policy, we show that rent control made tenants less NIMBY. Specifically, tenants in rent controlled apartments became more likely to approve of local-level construction and immigration, compared to tenants in non-rent-controlled apartments. We argue that the decline in NIMBYism is likely due to an economic channel. Tenants in urban centers associate construction and immigration with displacement pressures and gentrification. Rent control alleviates these concerns by providing financial and residential security.

Abstract 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 separate. The effect of Protestant missionaries on community cohesion is thus unclear. To make headway on these conflicting theoretical predictions, we study variation in missionary activity in southeastern Peru. We document that villages with Protestant missions show lower levels of community cohesion compared to non-missionized, Catholic villages. We point to weakened networks as the most likely causal channel and show that effect sizes are particularly large among Pentecostal missionaries.

abstract: 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, which created exogenous variation in government spending. A discontinuity in the 2011 German census meant that some municipalities saw an unforeseen increase in budgets. Using a regression discontinuity design, the authors show that the increase in budgets and subsequent spending on public goods benefited left-leaning parties but had no detectable effect on incumbent support. To parse out the causal channel, the authors rely on panel evidence and demonstrate that treated residents viewed their economic situation more favorably than did untreated residents, which led the former to espouse progressive parties.
