Studies have widely documented that women's descriptive representation in parliaments enhances their substantive representation. We probe this relationship under varying levels of women's collective and individual marginality based on an original dataset documenting the parliamentary behaviour of Israeli legislators over eleven parliamentary terms (1977–2015). Using several measures of individual-level marginality we show that marginalized female legislators are more prone to engage in gender-related parliamentary activity than their less marginal counterparts, albeit only under a certain threshold of women's marginality as a group. The article elucidates the dynamic nature of the relationship between descriptive and substantive representation of disadvantaged groups by demonstrating that it is contingent on their collective standing in parliament and on the marginality of individual legislators as manifested in their strategic choices.

Members of some legislatures enjoy long political careers, whereas elsewhere turnover is rampant. This variation is consequential since high-incumbency assemblies may facilitate legislative expertise at the expense of social representation. We explore cross-national differences in re-election (incumbency) rates by identifying ‘supply’ conditions such as legislative resources that benefit incumbents as well as ‘demand’ conditions such as political corruption that affect voters' willingness to re-elect incumbents. We hypothesize that legislative perquisites help incumbents win re-election, but only if there is relatively high public confidence in politics, as reflected in low corruption levels. We tested our argument using OLS and instrumental variable regression and new global data on sixty-eight democracies (2000–18) covering 288 elections and over 55,000 legislators. We found that legislative resources help incumbents get re-elected only under relatively low levels of political corruption. In contrast, under severe corruption, such resources can depress re-election rates.

How does candidate ideology affect donors' contribution decisions in U.S. House elections? Studies of donor motivations have struggled with confounding of candidate, donor, and district characteristics in observational data and the difficulty of assessing trade-offs in surveys. We investigate how these factors affect contribution decisions using experimental vignettes administered to 7,000 verified midterm donors. While ideological congruence influences donors' likelihood of contributing to a candidate, district competitiveness and opponent extremity are equally important. Moreover, the response to ideology is asymmetric and heterogeneous: donors penalize more moderate candidates five times more heavily than more extreme candidates, with the most extreme donors exhibiting the greatest preference for candidates even more extreme than themselves. Republicans also exhibit a greater relative preference for extremism than Democrats, although partisan differences are smaller than differences by donor extremism. Our findings suggest that strategic considerations matter, and donors incentivize candidate extremism even more than previously thought.

The implications of rising parliamentary representation of populist parties have been thoroughly studied but little is known about the impact of populist state leaders on party positions. In this article, we study mainstream parties' strategic responses when a populist takes over as the leader of a nation. We use content-analytical data and large language modelling to measure positions expressed in manifestos from parties from 51 democracies between 1989 and 2018. Employing methods for causal inference from observational data, we find that right-wing populist state leaders induce mainstream parties to differentiate their positions on multiculturalism, possibly leading to polarization of the party system. Under left-wing populist leaders, mainstream parties adopt more homogenous or differentiated positions, depending on the policy category and other contextual factors. Parties are generally more responsive in emerging than advanced countries and in presidential than parliamentary systems.

Terrorism elicits strong public reactions immediately after the attack, with important implications for democratic institutions and individual well-being. Are these effects short-lived? We answer this question using a natural experiment design and combining data on terrorist attacks in the United Kingdom with a Continuous Monitoring Survey. We find that heightened risk perceptions and emotional reactions in the wake of deadly attacks do not dissipate in the very short run but are sustained over time and up to 120 days after the attacks. Whereas large-scale attacks cause a long-lasting shift in risk assessments and emotions, the corresponding effect of smaller-scale terrorism incidents appears to subside within one month. Overall, the impact of terrorism does not fade away easily.

Political scientists have long been concerned that a popularly elected presidency may destabilize competitive party systems. We develop and test a new theory holding that the impact is more immediate and severe than previously assumed. Coexisting legislative and presidential coalitions first and foremost impede the evolution of predictable party interactions at the executive level, which is the domain of the cabinet. This quality has become accessible for comparative research thanks to the concept of party system closure. Using a new dataset for all European democracies since 1848, we show that presidential elections undermine party system closure in two ways: (1) by confounding patterns of government formation (notably under powerful presidencies) and (2) by disturbing electoral/legislative politics, which in turn affect executive politics. The former, direct effect emerges as dominant from a series of panel analyses and case illustrations. These findings have important implications for current problems of constitutional design and institutional reform.

We study a new driving factor of women's inclusion in politics: the economic empowerment of their mothers. We evaluate Swedish microdata on politicians and their parents over fifty years. The results demonstrate a strong intergenerational dynamic from mothers to daughters. Female politicians come from households where their mother is more likely to be employed, earns more in the labour market, and earns a larger share of household earnings. This pattern was strong among parliamentarians in the 1970s and 1980s when female numerical representation increased rapidly in Sweden but is not present in national politics after the introduction of gender quotas in the early 1990s or in local politics.

The literature on populism is divided on whether economic factors are significant and robust causes of populism. To clarify this, we performed the first systematic review and meta-analysis of the evidence of a causal association between economic insecurity and populism. We combined database searches with searching the citations of eligible studies and recently published reviews. We identified and reviewed thirty-six studies and presented a concise narrative summary and numerical synthesis of the key findings. Although we found significant heterogeneity in several dimensions, all studies reported a significant causal association. A recurrent magnitude was that economic insecurity explained around one-third of recent surges in populism. We tested for publication bias by conducting a funnel-plot asymmetry test and a density discontinuity test of the distribution of t-statistics. We found significant evidence of publication bias; however, the causal association between economic insecurity and populism remains significant after controlling for it.

What is the relationship between feminism and political participation? How does partisanship moderate this relationship? Prior research shows that gender attitudes, particularly sexism, rather than gender identity per se, increasingly shape vote choice and participation in US elections. However, the role played by feminism in voter behaviour remains scarcely understood. As feminist identification crosses partisanship, we argue that its impact on engagement with campaigns and turnout depends on party ID. Therefore, we expect feminist identity and how it intersects with either aligned or conflicting partisan identity to impact partisans' participation asymmetrically. Using data from the 2016 and 2020 American National Election Studies, our results support these expectations. Holding the mutually reinforcing identities of Democrat and feminist has a significant mobilizing impact, while holding the cross-cutting identities of Republican and feminist tends to lead to a decline in political participation.

A history of local inclusive institutions is correlated with higher levels of democracy today. However, it is unclear whether this reflects the effect of historical institutions on democracy or a prior common cause. Using a geographic natural experiment, this letter demonstrates that historical experience with inclusive institutions is related to less support for autocratic parties in nineteenth- and twentieth-century Germany. This suggests that electoral support for political parties that seek to subvert democracy can be influenced by pre-modern institutions even when they were destroyed prior to the introduction of democracy.

Understanding which political candidates are elected for office is fundamental to democracy and political science. Whereas there is much agreement that party affiliation is one of the most important candidate characteristics to voters, evidence regarding the gender and race of the candidate is mixed. We suggest voters have lexicographic preferences, meaning they rank their preferences and focus primarily on the candidate's party affiliation. Second-order preferences such as gender and race are mostly necessary when there is a tie in first-order preferences when voters choose between two same-party candidates or have no party information. We show how conjoint experiments can be used to test for lexicographic preferences and use data from a US-representative sample and a pre-registered replication to confirm that in the United States, gender and race are second-order preferences. Lexicographic preferences provide a theoretical lens explaining some of the mixed results of gender and race in the candidate literature.

Do negative economic shocks heighten public opposition to immigration, and through what mechanisms? Extant research suggests that economic circumstances and levels of labour market competition have little bearing on citizens' immigration attitudes. Yet personal economic shocks have the potential to trigger the threatened, anti-immigration responses – possibly through channels other than labour market competition – that prior cross-sectional research has been unable to detect. To examine these propositions, we used a unique panel study which tracked a large, population-based sample of Americans between 2007 and 2020. We found that adverse economic shocks, especially job losses, spurred opposition to unauthorized immigration. However, such effects are not concentrated among those most likely to face labour market competition from unauthorized immigrants. Instead, they are concentrated among white male Americans. This evidence suggests that the respondents' anti-immigration turn does not stem from economic concerns alone. Instead, personal experiences with the economy are refracted through salient socio-political lenses.

Through an innovative analysis of audio recordings of plenary speeches, Dietrich, Hayes, and O'Brien (2019) find that women in the U.S. House of Representatives speak with greater emotional intensity about women than other issues. With vocal pitch as a new measure of personal issue commitment, the finding suggests that women legislators' efforts to work on behalf of women result from intrinsic motivation. I ask whether the same is true in an alternative parliamentary setting, the German Bundestag, where personal preferences play a very different role due to strict party discipline. The answer is yes. Analyzing audio and text data from more than 30,000 speeches in the Bundestag between 2011 and 2020, I find that women in the Bundestag address women more frequently and with greater emotional intensity than men. The results suggest that women legislators are more emotionally invested in women-related issues than men.

Do the rich become more or less supportive of redistribution when exposed to poor people in their local surroundings? Most existing observational studies find that exposure to poor individuals is positively associated with support for redistribution among the well-off, but one prominent field experiment found a negative link. We seek to resolve these divergent findings by employing a design closer to the studies that have found a positive link, but with more causal leverage than these; specifically, a three-wave panel survey linked with fine-grained registry data on local income composition in Denmark. In within-individual models, increased exposure to poor individuals is associated with lower support for redistribution among wealthy individuals. By contrast, between-individual models yield a positive relationship, thus indicating that self-selection based on stable individual characteristics likely explains the predominant finding in previous work.

Bølstad and Dinas (2017) propose a model of spatial voting, based on social identity theory, that suggests supporting a candidate/policy on the other side of the ideological spectrum has a disutility that is not accounted for by common spatial models. Unfortunately, the data they use cannot speak directly to whether the disutility arises because individuals perceive their ideology as a social identity. We present the results of an experimental study that measures the norm against crossing the ideological spectrum; tests the cost of doing so, controlling for spatial effects; and demonstrates that this cost increases with the salience and strength of identity norms. By demonstrating the norm mechanism for the disutility of crossing the ideological spectrum, we provide strong support for B&D's model.

Racial and ethnic minorities are underrepresented in most Western democracies. This article investigates one potential root cause behind this pattern: minority and majority citizens might expect to feel discriminated against if they enter politics. Using data from three large-scale surveys, we find that minorities in both the United States and Sweden are less likely to expect to feel welcome than the majority population. These discrepancies in expected discrimination persist, even after controlling for other factors. Moreover, expected discrimination is not without political consequences: those who expect to feel less welcome are less likely to indicate an interest in running for political office. Finally, these results do not differ for politically engaged citizens who constitute a more realistic pool of potential candidates. We conclude by discussing what expectations of discrimination can tell us about the fairness of the political system and how these attitudes shape political ambition among minorities.

Government competence in delivering outcomes is often regarded as foundational to political trust. However, in this article, a different competence dynamic is proposed; specifically, whether political trust is related to government efficiency in achieving promised policy objectives. This article argues that when policy objectives are polarizing, the effect of efficiency on political trust is conditional on whether individuals support or oppose the objective. Using the case of Brexit, where the promised policy objective of leaving the European Union was polarizing, it is hypothesized that Leave voters relative to Remain voters became more trusting in cases of efficiency and less trusting in cases of inefficiency. The predictions are supported through a difference-in-differences analysis of unique real-world data over time from the British Election Study. The findings have important implications for our understanding of Brexit and also inform how political trust relates to government competence in the case of polarizing political issues.
