Democracy assistance, including the promotion of electoral security, is often a central component of contemporary peacekeeping operations. Preventing violence during post-conflict elections is critical for the war-to-democracy transition. Yet little is known about the role of peacekeepers in this effort. To fill this gap, this study provides the first comprehensive sub-national study of peacekeeping effectiveness in reducing the risk of electoral violence. It combines geo-referenced data on peacekeeping deployment across all multidimensional peacekeeping missions in Africa over the past two decades with fine-grained data on electoral violence. The analysis finds a negative association between peacekeeping presence and the risk of electoral violence. The relationship is of a similar magnitude in the pre- and post-election periods. However, the association is more strongly negative for violence perpetrated by non-state actors compared to violence perpetrated by government-affiliated actors. Analyses using two-way fixed-effects models and matching mitigate potential selection biases.

By many measures, the public knows little about politics. But just how little people seem to know depends on the questions that are put to them. In particular, knowledge levels seem higher when people are asked closed- rather than open-ended questions. In turn, differences between estimated knowledge levels are sometimes attributed to fundamental differences between these types of questions. Building on this previous research, the present study uses a pre-registered experiment conducted with a representative national sample to shed new light on the relationship between question form and knowledge measurement. The authors find that inferences about political knowledge depend less on fundamental differences between open- and closed-ended questions than on two little-appreciated aspects of survey design: the number and difficulty of the response options that accompany closed-ended questions. These aspects of survey design have large effects. Scholars who use the same questions with different response options may reach substantively different conclusions about the public's levels of knowledge.

How can the growing personalization of power be identified and measured ex ante? Extant measures in the authoritarian literature have traditionally focused on institutional constraints and more recently on individual behaviour – such as purging opposition members from (and packing allies into) government bodies. This article offers a different strategy that examines leaders’ individual rhetoric. It focuses on patterns of pronoun usage for the first person. The author argues that as leaders personalize power, they are less likely to use ‘I’ (a pronoun linked to credit claiming and blame minimizing) and more likely to use ‘we’ (the leader speaks for – or with – the populace). To test this argument, the study focuses on all major, scheduled speeches by all chief executives in the entire Chinese-speaking world – that is, China, Singapore and Taiwan – since independence. It finds a robust pattern between first-person pronouns and political constraints. To ensure the results are not driven by the Chinese sample, the rhetoric of four other political leaders is considered: Albania's Hoxha, North Korea's Kim Il Sung, Hungary's Orbán and Ecuador's Correa. The implications of this project suggest that how leaders talk can provide insights into how they perceive their rule.

How can one assess which countries select more experienced leaders for the highest office? There is wide variation in prior career paths of national leaders within, and even more so between, regime types. It is therefore challenging to obtain a truly comparative measure of political experience; empirical studies have to rely on proxies instead. This article proposes PolEx, a measure of political experience that abstracts away from the details of career paths and generalizes based on the duration, quality and breadth of an individual's experience in politics. The analysis draws on a novel data set of around 2,000 leaders from 1950 to 2017 and uses a Bayesian latent variable model to estimate PolEx. The article illustrates how the new measure can be used comparatively to assess whether democracies select more experienced leaders. The authors find that while on average they do, the difference with non-democracies has declined dramatically since the early 2000s. Future research may leverage PolEx to investigate the role of prior political experience in, for example, policy making and crisis management.

Studies of the causes of social unrest typically focus on structural factors or diffusion. This article demonstrates the importance of considering their interaction and reveals a complex interplay between the two. This interaction is examined in the context of the English Swing riots of 1830–1831, in which it is possible to observe the structural factors relevant to each specific incident; this is often impossible when analyzing more recent cases of unrest. The authors find that the riots were triggered by economic factors and that diffusion more than tripled the direct effect of changes in local factors. Economic factors and the presence of potential riot leaders made an area more susceptible to the incoming diffusion of riots. The ways in which structural factors and diffusion interact is relevant to both historical and recent instances of social unrest.

Vast research on immigration lumps together native citizens' attitudes toward two different groups: the immigrant stock of non-naturalized resident aliens, and the immigrant flow, that is, the future arrival of foreigners seeking to enter and live in the country. Does popular opposition to immigration distinguish between the two, and if so, how? This article analyzes theoretically the reasons the stock and flow might induce different views among natives, and presents experimental evidence from the United States showing that natives are systematically more accepting of the former. The analysis indicates that this ‘stock premium’ partly stems from a sense of moral obligation toward people residing in the country. Replicating two widely cited experiments, the study shows that the stock–flow distinction has important implications for the interpretation of earlier findings on immigration attitudes, and for understanding voter preferences regarding policies designed to curtail immigration.

This article contributes to the recent research on Brexit and public opinion formation by contending that the determinants of the referendum results should be evaluated against the background of wider public security concerns. The British public has long regarded terrorism as a top concern, more so than in any other European country. Terrorist attacks on UK soil raised voters' awareness of security issues and their saliency in the context of the EU referendum. The study finds that locations affected by terrorist violence in their proximity exhibit an increase in the share of pro-Remain votes, particularly those that experienced more sensational attacks. Using individual-level data, the results show that in the aftermath of terrorist attacks, citizens are more likely to reconsider the security risks involved in leaving the EU.

This paper examines the relationship between the coming of the railroads, the expansion of primary education, and the introduction of national school curricula. Using fine-grained data on local education outcomes in Sweden in the nineteenth century, the paper tests the idea that the development of the railroad network enabled national school inspectors to monitor remote schools more effectively. In localities to which school inspectors could travel by rail, a larger share of children attended permanent public schools and took classes in nation-building subjects such as geography and history. By contrast, the parochial interests of local and religious authorities continued to dominate in remote areas school inspectors could not reach by train. The paper argues for a causal interpretation of these findings, which are robust for the share of children in permanent schools and suggestive for the content of the curriculum. The paper therefore concludes that the railroad, the defining innovation of the First Industrial Revolution, mattered directly for the state's ability to implement public policies.

How does globalization affect politics? One of the most controversial aspects of globalization is offshoring, when manufacturing operations and business functions move abroad. Although voters generally dislike offshoring, it remains unclear how moving jobs abroad impacts democratic elections. Using a difference-in-differences estimation strategy, the author finds that incumbent government parties lose more votes in municipalities where a local plant moved production abroad between elections than in municipalities that did not experience such an event. The result holds across various time periods, different incumbent parties and diverse types of elections. In both national and regional elections, voters punish incumbent government parties when a local firm moves production abroad. Incumbent parties' vote shares fall as the number of jobs lost due to offshoring increases. In multiparty governments, voters disproportionately punish the largest coalition party for offshoring. The results of an original survey administered in Spain verify the importance of offshoring for voters' retrospective evaluations of incumbents.

Scholars have examined the role that negative stereotypes play in electoral discrimination against minority candidates. Incorporating literature on in-group favoritism, the author argues here that some degree of this discrimination can be explained instead by voters holding positive stereotypes of majority candidates and discriminating in their favor. Based on the results of an original moderation-of-process survey experiment carried out in Italy, the study provides evidence of electoral discrimination pertaining to immigrant-origin candidates, concentrated among right-wing citizens. It finds that stereotypes have little mediating effect on discrimination against candidates with a migration background; rather, the primary role played by stereotypes is in discrimination in favor of majority candidates, that is, positive bias that reserves electoral benefits to them. The relevance of in-group favoritism is corroborated by the finding that large segments of the Italian voting population hold distinctively positive stereotypes of majority candidates without also negatively stereotyping immigrant-origin candidates.

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.

Does enhanced descriptive representation lead to substantive representation? Legislators who share descriptive features with disadvantaged groups do not necessarily represent their group interests. Instead, Members of Parliament (MPs) strategically choose when to engage with the policy topic of their corresponding groups. MPs represent their respective group at the beginning of their career because it confers credibility when they have no legislative track record and few opportunities to demonstrate expertise. These group-specific efforts are replaced by other legislative activities at later stages of their careers. The authors apply this theoretical expectation across four disadvantaged groups – women, migrants, low social class and the young – and thereby offer a broad perspective on descriptive representation. Their sample consists of a unique data base that combines biographical information on German MPs with topic-coded parliamentary questions for the period 1998 to 2013. The study demonstrates the diminishing value of representing the disadvantaged across different types of MPs.

How do parties decide when to campaign on valence issues given high degrees of uncertainty? Although past studies have provided evidence of transnational emulation of parties' position-taking strategies, these findings do not directly apply to saliency strategies. Moreover, the exact diffusion mechanism remains largely elusive. Based on the issue saliency literature, this study develops novel theoretical propositions and argues that conscious learning enables parties to infer the relative utility of emphasizing consensual issues during an electoral campaign. The proposed theory gives rise to different expectations at the domestic and transnational levels because of the distinct logic of issue competition. By analyzing environmental issue emphasis in party manifestos, the authors find direct transnational dependencies and indirect spillover effects among the parties' saliency strategies. They identify conscious learning, rather than mere imitation or independent decision making, as the diffusion mechanism at work. Yet, in line with saliency-based theories, electoral competition mutes the diffusion of electoral strategies domestically.

There has been a lively debate about the economic and cultural-based drivers of support for populism. This article argues that economic concerns matter, but that they are realized through the relative gains and losses of social groups. Using new survey items in a large representative survey administered in Britain, it shows that citizens' economic assessments of the ethnic minority out-group – in relation to the group's situation 12 months ago and to assessments of the economic conditions of the white British in-group – are a predictor of support for Brexit. The results, which are robust to prior referendum vote, immigration attitudes and cultural sentiment, extend across income groups and national identity strength. Extending the analysis to a comparison of geographic in- and out-groups between local communities and London lends additional support to the argument. The implications of relative group-based economics are important for understanding Brexit and the economic sources of support for populism more broadly.

Given the prevalence of riots throughout human history, the lack of normative theorizing about them compared to other forms of political violence is striking. The author hypothesizes that this is due to riots' extra-institutionality. Riots are extra-public because they involve the participation of crowds, rather than institutionalized groups such as parties or social movements. They are extra-state because they violate the state's monopoly on violence. Riots are extra-legal because they constitute a form of unlawful assembly. They are also extra-parliamentary because they operate outside the normal legislative process. This article considers justifiable reasons to resist each of these foundational institutions, and proposes provisional criteria for a justifiable riot. The author concludes by urging political theorists to further examine the normative dimension of riots.

Holding elected officials accountable for their behavior in office is a foundational task facing citizens. Elected officials attempt to influence this accountability process by explaining their behavior with an eye toward mitigating the blame they might receive for taking controversial actions. This article addresses a critical limitation in the literature on elite explanation giving and accountability: the absence of attention to conflicting information regarding the official's behavior. The study shows across three pre-registered survey experiments that explanations are ineffective when other speakers offer counter-explanations that focus on the official's potential ulterior motives. It further demonstrates that this occurs even when the counter-explanation comes from a partisan source with low credibility. These results imply that elected officials enjoy less leeway for their actions than existing work allows, and highlight important tensions concerning the relationship between elite behavior and accountability processes.

Prior research suggests that partisanship can influence how legislators learn from each other. However, same-party governments are also more likely to share similar issues, ideological preferences and constituency demands. Establishing a causal link between partisanship and policy learning is difficult. In collaboration with a non-profit organization, this study isolates the role of partisanship in a real policy learning context. As part of a campaign promoting a new policy among local representatives in the United States, the study randomized whether the initiative was endorsed by co-partisans, out-partisans or both parties. The results show that representatives are systematically more interested in the same policy when it is endorsed by co-partisans. Bipartisan initiatives also attract less interest than co-partisan policies, and no more interest than out-partisan policies, even in more competitive districts. Together, the results suggest that ideological considerations cannot fully explain partisan-based learning. The study contributes to scholarship on policy diffusion, legislative signaling and interest group access.

Does exposure to cyber terrorism prompt calls for retaliatory military strikes? By what psychological mechanism does it do so? Through a series of controlled, randomized experiments, this study exposed respondents (n = 2,028) to television news reports depicting cyber and conventional terror attacks against critical infrastructures in the United States, United Kingdom and Israel. The findings indicate that only lethal cyber terrorism triggers strong support for retaliation. Findings also confirm that anger bridges exposure to cyber terrorism and retaliation, rather than psychological mechanisms such as threat perception or anxiety as other studies propose. These findings extend to the cyber realm a recent trend that views anger as a primary mechanism linking exposure to terrorism with militant preferences. With cyber terrorism a mounting international concern, this study demonstrates how exposure to this threat can generate strong public support for retaliatory policies, depending on the lethality of the attack.

Scholars have long noted that couples are more likely to vote compared to individuals who live alone, and that partners' turnout behavior is strongly correlated. This study examines a large administrative dataset containing detailed information about validated turnout and the timing of individuals moving in together, and finds evidence of a substantial and robust increase in turnout after cohabitation. The study exploits the fact that two-voter households moving in together right before an election are comparable to those moving in together right after the election. Depending on the model specification, turnout increases by 3.5 to 10.6 percentage points in the months after taking up cohabitation. Voters are mobilized regardless of their own and their cohabitant's turnout behavior in a previous election. The results are robust to several robustness checks, including benchmarking with singles who move to mitigate the cost of moving in the analysis. The results highlight the importance of social norms and the household's essential role as a proximate social network that increases turnout.
