There is a continuing debate over the political importance and durability of partisan attachments in European multi-party systems. Drawing on a nationally representative five-wave panel, we provide a longitudinal test of the power of partisanship in Italy over the course of the tumultuous 2013 national elections. We find that a strong partisan affiliation measured as a social identity two years prior to the election promoted system stability by increasing support for the in-party and inhibiting electoral support for the insurgent Five Star Movement (M5S). In contrast, non-partisans, especially highly educated ones, were more likely than partisans to vote for M5S. Our results illustrate the role of partisanship in stabilizing multi-party systems amid crisis.

Research has shown that presidents tend to benefit local level copartisans when distributing resources, which can improve the provision of public goods, such as security. Considering that fear of crime is among the main concerns of citizens worldwide, we examine whether alignment affects criminality. Drawing on rich administrative data from Chile and a regression discontinuity design in close electoral races, we study the impact of alignment on a broad set of crimes against the person and property-related. We show that aligned municipalities experience a significant reduction in crimes that both affect property and occur in public. As a potential mechanism, we find that aligned municipalities receive more projects to improve urban infrastructure, thus making public spaces less vulnerable to crime.

Violent hostility between ordinary partisans is undermining American democracy. Social media is blamed for rhetoric threatening violence against political opponents and implicated in offline political violence. Focusing on Twitter, I propose a method to identify such rhetoric and investigate substantive patterns associated with it. Using a data set surrounding the 2020 Presidential Election, I demonstrate that violent tweets closely track contentious politics offline, peaking in the days preceding the Capitol Riot. Women and Republican politicians are targeted with such tweets more frequently than men and non-Republican politicians. Violent tweets, while rare, spread widely through communication networks, reaching those without direct ties to violent users on the fringe of the networks. This paper is the first to make sense of violent partisan hostility expressed online, contributing to the fields of partisanship, contentious politics, and political communication.

Diversity's effect on violence is ambiguous. Some studies find that diverse areas experience more violence; others find the opposite. Yet conflict displaces and intimidates people, creating measurement challenges. We propose a novel indicator of diversity that circumvents these problems: the location of physical structures at disaggregated geographical levels. We introduce this solution in the context of the Troubles in Northern Ireland. Our data reveal a curvilinear relationship between diversity and conflict-related deaths, with the steepest increase at low diversity, driven by an increase in violence when our proxy for the Catholic proportion of the population rises from 0 to 20 percent. These patterns are consistent with a theory of group threat through exposure.

Most authoritarian countries censor the press. As a response, many opposition and independent news outlets have found refuge on the Internet. Despite the global character of the Internet, news outlets are vulnerable to censorship in cyberspace. This study investigates Denial-of-Service (DoS) attacks on news websites in Venezuela and details how news reporting is related to DoS attacks in an attempt to censor content. For this empirical test, I monitored 19 Venezuelan news websites from November 2017 until June 2018 and continuously retrieved their content and status codes to infer DoS attacks. Statistical analyses show that news content correlates to DoS attacks. In the Venezuelan context, these news topics appear to be not only on protest and repression but also on opposition actors or other topics that question the legitimacy of the regime. By establishing these relationships, this study deepens our understanding of how modern technologies are used as censorship tools.

Does increasing executive power necessarily decrease accountability? To answer this question, I develop a two-period signaling model comparing voter welfare in two separation-of-powers settings. In one, the executive works with a median legislator to change policy; in the other, the executive chooses between legislation or unilateral action. Both politicians may have preferences that diverge from the voter's, yet I find that increasing executive power may increase accountability and welfare, even in some cases when the legislator is more likely to share the voter's preferences than the executive. Unilateral power allows a congruent executive to overcome gridlock, implement the voter's preferred policy, and reveal information about the politicians’ types—which can outweigh the risks of a divergent executive wielding power for partisan ends.

How do politicians distribute government resources in regimes with no electoral considerations? We propose that new politicians minimize political risks by favoring politically important actors: state-owned enterprises (SOEs), but they adjust their behavior as they establish personal ties with private businesses. Using firm-level subsidies data after the 2008 stimulus in China, we find that new provincial governors, immediately after taking office, distribute a significantly larger proportion of subsidies to SOEs relative to private firms. The effect attenuates as new governors learn about local conditions and establish connections with private firms. We find suggestive evidence that governors who adopt such a strategy are more likely to be promoted. Contrary to conventional wisdom that the state always favors state-owned firms, we show that SOEs benefit from the stimulus package only in the short-run.

How do rebels choose among available tactics during civil war? How do they substitute one tactic for another? Although previous studies address these questions, they narrowly focus on the presence or absence of substitution. Differentiating the varieties of substitution, however, is critical. How rebels respond to their tactical environment—including weather conditions—depends on the type of substitution. I formally derive three types of substitution and test them by exploiting weather-induced exogenous variation in rebels' tactical costs for ground and marine violent activities. The analysis of daily panel data in 31 coastal conflict countries indicates that rebels substitute violent ground activities for maritime piracy but not vice versa. This asymmetry cannot be explained without differentiating substitution types.

How well do citizens understand the associations between social groups and political divisions in their societies? Previous research has indicated systematic biases in how the demographic composition of party supporters are perceived, but this need not imply that citizens misperceive the likely voting behavior of specific individuals. We report results from two experiments where subjects were provided with randomly selected demographic profiles of respondents to the 2017 British Election Study (BES) and then asked to assess either (1) which party that individual was likely to have voted for in the 2017 UK election or (2) whether that individual was likely to have voted Leave or Remain in the 2016 UK referendum on EU membership. We find that, despite substantial overconfidence in individual responses, on average citizens’ guesses broadly reflect the actual distribution of groups supporting the parties and referendum positions.

Even though social investment is highly popular, welfare state recalibration remains an uphill battle. When resources are scarce in times of austerity, welfare recalibration involves multidimensional trade-offs. Existing research primarily studied preferences toward individual policies or trade-offs in specific policy fields, failing to capture citizens’ overall social policy priorities. Using two novel survey experiments in three European countries, we show that citizens have clear social policy priorities: pensions and education enjoy a high, family policies a medium, and labor market policies a low priority. However, policy constituencies differ in their relative priorities. Our findings suggest that welfare state recalibration is difficult because trade-offs are unpopular, and distributive conflicts in mature welfare states are mainly about distributing resources to specific social groups.

What is the effect of external economic intervention on political support and economic evaluations? We argue that economic interventions systematically worsen support for governing institutions and much of this is mediated through updating economic perceptions, at least during the Eurozone crisis. We evidence this with two analyses. First, we provide the first quasi-experimental evidence to show that intervention worsened both political support and economic evaluations. Second, we conduct a mediation analysis using Eurobarometer data to quantify how much of the effect of intervention is mediated by economic evaluations. This has broader implications for understanding how citizens react to international integration, international cues, and the process of forming judgements of political support.

Democracy relies on citizens who are politically knowledgeable and engaged. However, when a voter gains political knowledge regarding important issues, through television, town halls, or social media, she also learns that there are many other politically knowledgeable voters, highlighting the importance of social knowledge in political participation. Will a voter with concrete—as opposed to hypothetical—knowledge about other voters’ political knowledge have an increased incentive to participate? Or instead, will concrete social knowledge about other voters actually inhibit participation? In this article, we develop a novel experimental design that focuses on whether concrete knowledge about other voters’ political knowledge influences political participation. Our main result shows that concrete social knowledge decreases individual voters’ willingness to vote, and thereby reduces the probability democracy chooses the majority preferred alternative, i.e. the quality of democratic choice.

Growing attitudinal and affective differences across party lines and increasing social polarization are often attributed to the strengthening of partisanship as a social identity. Scholars have paid less attention to personal preferences as a contributor to these phenomena. Our focus is on how citizens’ policy beliefs—their operational ideologies—are associated with their views of partisan groups. We examine our perspective with two studies. In the first, we find that the attribution of ideologically extreme political views to an individual's peer significantly reduces interest in interpersonal interaction but find limited evidence that partisan group membership alone induces social polarization. In the second, we show that citizens’ policy views are strongly associated with their perceptions of their own partisan group as well as their counterpartisans. Together, our results have important implications for understanding the consequences of increased polarization and partisan antipathy in contemporary politics.

This paper introduces a new approach to the quantitative study of democratization. Building on the comparative case-study and large-N literature, it outlines an episode approach that identifies the discrete beginning of a period of political liberalization, traces its progression, and classifies episodes as successful versus different types of failing outcomes, thus avoiding potentially fallacious assumptions of unit homogeneity. We provide a description and analysis of all 383 liberalization episodes from 1900 to 2019, offering new insights on democratic “waves”. We also demonstrate the value of this approach by showing that while several established covariates are valuable for predicting the ultimate outcomes, none explain the onset of a period of liberalization.

Does exposure to a mass migration event cause citizens to vote against incumbents? I offer an answer to this question by studying one of the largest acute periods of migration in the US, the case of the 1980 Mariel Boatlift during which roughly 125,000 Cubans fled to South Florida. I estimate the change in support for Republican presidential candidates in Miami using the synthetic control method and fixed effects regressions with a panel of county-level and archival precinct-level election results. I find that, while Miami voters dramatically increased their support of the Republican candidate in 1980, this shift was not a local consequence of the Boatlift. Instead, the evidence suggests that Cuban support for Reagan was not a local Miami response to the Boatlift—it happened in Cuban communities throughout the US—but it was most noticeable in Miami because Miami had the largest Cuban population in the US even before the Boatlift. I also present evidence that this change in Cuban voting may have been specific to Reagan and not a broader shift against incumbents or toward Republicans. These findings suggest that, in this case, direct exposure to migration did not lead citizens to dramatically change their voting behavior.

Security forces are one of the main targets of political violence. This paper examines the effect of their casualties on electoral outcomes. Between two general elections in 2015, Turkey experienced a series of attacks that killed 153 members of its security forces. Based on the as-if random assignment of their funerals across the country, I estimate that government vote share increases in the funeral places of security force terror victims. However, in the localities with recurring funerals, it decreases by a similar percentage. These non-linear changes provide strong evidence for the rally theory.

This study explores the consequences of legislative turnover for the hiring of lobbyists and influence of interest groups. We argue that lobbyists develop durable relationships with lawmakers in assemblies with low turnover. Such relationships allow lobbyists to attract clients. We use a new, state-level measure of multi-client lobbying to show that legislative turnover and multi-client lobbying are inversely related: decreases in turnover are correlated with more multi-client lobbying. In a second set of analyses, we find that legislative term limits are associated with less multi-client lobbying. Since multi-client lobbying poses risks to the representation of individual interests and magnifies the effects of resource differences between interests, our results suggest that turnover may help more diverse interests to achieve political influence.

Does a universal basic income (UBI) affect voter turnout? This article argues that the introduction of an unconditional cash payment—where citizens receive money independent of employment status, age, or indigence—can have a turnout-enhancing effect. I evaluate the argument using the introduction of the Permanent Fund Dividend in Alaska. Differences-in-differences estimates covering November general elections from 1978 to 2000 provide compelling evidence that the Alaskan UBI has a significant positive effect on turnout. The results further suggest that the turnout increase was not a one-off effect but persists over a period of almost 20 years. Thus, a UBI has the potential to positively affect turnout among an entire electorate, adding to the discussion around potential welfare reforms in western democracies.

Respondent inattentiveness threatens to undermine causal inferences in survey-based experiments. Unfortunately, existing attention checks may induce bias while diagnosing potential problems. As an alternative, we propose “mock vignette checks” (MVCs), which are objective questions that follow short policy-related passages. Importantly, all subjects view the same vignette before the focal experiment, resulting in a common set of pre-treatment attentiveness measures. Thus, interacting MVCs with treatment indicators permits unbiased hypothesis tests despite substantial inattentiveness. In replications of several experiments with national samples, we find that MVC performance is significantly predictive of stronger treatment effects, and slightly outperforms rival measures of attentiveness, without significantly altering treatment effects. Finally, the MVCs tested here are reliable, interchangeable, and largely uncorrelated with political and socio-demographic variables.

China after Mao is typically characterized as a country where economic opportunities are based on merit instead of ideological conformity. However, the salience of ideology has grown under the rule of Xi Jinping. Using a large-scale resume audit experiment and a conjoint survey experiment of hiring managers in China, we find that firms in China do not reward job candidates for expressing conformity to the ideology of the regime, but job candidates who express support for Western democracy are less employable. Results suggest that firms in innovative industries designated as strategically important by the Chinese regime (e.g., artificial intelligence) penalize support for Western democracy by the largest magnitude while the remaining firms in innovative industries do not penalize political non-conformity.
