    Examining Voting Spillover Effects of Text Message Reminders

    by Karl-Oskar Lindgren, Pär Nyman, Sven Oskarsson

    We present results from a pre-registered, well-powered $(N \gt 3,000,000)$ text message get-out-the-vote (GOTV) experiment, conducted during the 2019 European Parliament election in Sweden. Our findings suggest that a simple text message increases the likelihood of voting by 0.3 percentage points. Half of this effect spills over to untreated household members while workplace spillovers are near zero. Subsequent analysis reveals that the direct treatment effect is noticeably stronger among individuals with below-average voting propensities. Interestingly, within this same group, the household spillovers are significantly negative. We speculate and provide some indirect evidence, that these negative spillover effects may stem from the text message reminder influencing the behaviour of voters already motivated to vote. Above all, we propose that an increase in early voting, as opposed to voting on Election Day, among treated individuals may weaken the mechanisms thought to explain spillover effects since voters are less likely to bring their family members with them when voting early.

    Granting Immigrants the Right to Vote in National Elections: Empirical Evidence from Swedish Administrative Data

    by Linuz Aggeborn, Henrik Andersson, Sirus H. Dehdari, Karl-Oskar Lindgren

    Faced with rising levels of cross-border migration, many countries have extended local voting rights to non-citizen residents. However, empirical evidence indicates that voter turnout among non-naturalized immigrants is lower when compared to citizens. This raises the question of how to explain this difference. A common answer is that the low turnout rates of non-citizen residents are primarily due to the socio-economic composition of this group and the challenges involved in adapting to a new political system. An alternative but less discussed possibility is that the low turnout concerns the nature of the elections. Hence, we examine whether the turnout of non-citizens is hampered because they are only allowed to partake in local elections. Based on a regression discontinuity design (RDD) using Swedish administrative data, we find that turnout could increase by 10–20 percentage points if the voting rights of non-citizens were extended to the national level.

    The Perpetuity of the Past: Transmission of Political Inequality across Multiple Generations

    by Karl-Oskar Lindgren, Sven Oskarsson

    It is a well-established fact, from decades of research on political socialization, that the children of politically active parents are more likely to become politically active themselves. This poses a challenge for democracy, as it means that inequalities in political influence are reproduced across generations. The present study argues that this problem may be more severe than has hitherto been acknowledged. The reason for this is that previous research on the topic has focused almost exclusively on political transmission between parents and their children, whereas the role played by more distant forebears, such as grandparents, has been largely neglected. In this study, we use Swedish register data to analyze multigenerational associations in electoral participation. The empirical results clearly indicate that the traditional two-generation approach to the study of political transmission tends to underestimate intergenerational persistence in voting behavior and that this excess persistence has both genetic and social roots.

    Opening a door to politics? Labour market entrance and political candidacy among refugees

    by Karl-Oskar Lindgren, Marcus Österman

    In this study, we explore whether the economic integration of immigrants may function as a stepping stone to their political integration. We show that there are strong theoretical reasons to expect entrance into the labour market to be pivotal for the political socialisation of immigrants in the new host country and in extension for their opportunities to stand for office. Empirically, we make use of Swedish register data and study whether labour market entrance among refugees affects their chances of being nominated for political office in Swedish municipal councils. We focus on refugees that arrived in Sweden between 1985 and 1994 and explore whether they became political nominees in seven consecutive elections between 1994 and 2014. Our results indicate that getting an early foothold in the labour market has a significant positive effect on the likelihood of running for office. These results hold even when we make use of more exogenous variation in the labour market conditions that refugees encountered when they arrived in Sweden, which provides some support that labour market entrance may have a causal effect on political candidacy among refugees.

    The Ex-Factor: Examining the Gendered Effect of Divorce on Voter Turnout

    by Sirus H. Dehdari, Karl-Oskar Lindgren, Sven Oskarsson, Kåre Vernby

    The absence of a gendered analysis of the effect of marriage on voting is surprising given researchers’ cognizance of the heterogeneous effects of marriage on a range of other social outcomes. In this paper, we shed new light on spousal dependency by studying the gendered effect of marital disruption, in the form of divorce, on voter turnout. First, drawing on Swedish populationwide data, we use the differential timing of divorces in relation to general elections to generate more credible estimates of the causal effect of divorce on turnout. Second, although we find that both sexes are adversely affected by divorce, we show that the effect is much more pronounced for men. Specifically, the long-term effect is almost twice as large for men. Finally, we use these data to show that the gendered effect of divorce is mainly driven by asymmetrical spousal mobilization due to higher levels of turnout among women.

    Immigrant Political Representation and Local Ethnic Concentration: Evidence from a Swedish Refugee Placement Program

    by Karl-Oskar Lindgren, Michael D. Nicholson, Sven Oskarsson

    This study leverages population registry data from Sweden to examine whether immigrants who live in areas with a high concentration of ethnic minorities are more or less likely to be nominated for political office. It exploits a refugee placement program in place in Sweden during the late 1980s and early 1990s that restricted refugees' opportunities to freely choose their place of residence. The article presents evidence that immigrants who live in areas with a high ethnic density are less likely to be nominated for political office. The findings have important implications for local integration policies as well as refugee placement policies, as many countries consider local context when resettling refugees.

    Candidate Supply Is Not a Barrier to Immigrant Representation: A Case–Control Study

    by Rafaela Dancygier, Karl‐Oskar Lindgren, Pär Nyman, Kåre Vernby

    Immigrants are underrepresented in most democratic parliaments. To explain the immigrant–native representation gap, existing research emphasizes party gatekeepers and structural conditions. But a more complete account must consider the possibility that the representation gap begins at the supply stage. Are immigrants simply less interested in elected office? To test this explanation, we carried out an innovative case–control survey in Sweden. We surveyed elected politicians, candidates for local office, and residents who have not run; stratified these samples by immigrant status; and linked all respondents to local political opportunity structures. We find that differences in political ambition, interest, and efficacy do not help explain immigrants' underrepresentation. Instead, the major hurdles lie in securing a candidate nomination and being placed on an electable list position. We conclude that there is a sufficient supply of potential immigrant candidates, but immigrants' ambition is thwarted by political elites.

    Birth Order and Voter Turnout

    by Bernt Bratsberg, Christopher T. Dawes, Andreas Kotsadam, Karl-Oskar Lindgren, Richard Öhrvall, Sven Oskarsson, Oddbjørn Raaum

    Previous studies have stressed the role of a child's family environment for future political participation. This field of research has, however, overlooked that children within the same family have different experiences depending on their birth order. First-borns spend their first years of life without having to compete over their parents' attention and resources, while their younger siblings are born into potential rivalry. We examine differences in turnout depending on birth order, using unique population-wide individual level register data from Sweden and Norway that enables precise within-family estimates. We consistently find that higher birth order entails lower turnout, and that the turnout differential with respect to birth order is stronger when turnout is lower. The link between birth order and turnout holds when we use data from four other, non-Nordic countries. This birth order effect appears to be partly mediated by socio-economic position and attitudinal predispositions.
