Die Wahl der Integrationsräte auf Kommunalebene ist für Nicht-EU-Ausländer*innen faktisch die einzige Möglichkeit elektoraler politischer Interessenartikulation. Gleichzeitig sind die politischen Gestaltungsmöglichkeiten von Integrationsräten begrenzt und die Wahlbeteiligung bei Integrationsratswahlen ist typischerweise deutlich geringer als die Wa...
Article
Communities are responsible for a range of public services and represent critical experiential contexts for social interactions between residents. However, the role of local governance and public service provision for creating social trust has received limited attention so far. This study examines how quality, efficiency and fairness of local publi...

Findings from 162 researchers in 73 teams testing the same hypothesis with the same data reveal a universe of unique analytical possibilities leading to a broad range of results and conclusions. Surprisingly, the outcome variance mostly cannot be explained by variations in researchers’ modeling decisions or prior beliefs. Each of the 1,261 test mod...

Welfare chauvinism in the context of immigration refers to the belief that immigrants are “free-riders” who receive social benefits without having contributed adequately. This chapter reviews personal and contextual foundations of welfare chauvinistic beliefs in immigrant-receiving societies in Western Europe. In doing so, we focus on matters relat...

This study examines citizens' support for state surveillance, contingent upon factors related to policy design and the context of implementation. While most people want to live in a secure environment, we argue in this study that the support of policies to reach this goal depends on their necessity, extensiveness and reliability. Results from surve...
Article
Immigrants’ economic progress, on the one hand, serves as an indicator of successful integration and should serve to mitigate natives’ concerns about potential economic or welfare state–related burdens of immigration. On the other hand, the fact of immigrants improving their social status may also induce perceptions of competition and group-related...

The European Parliament (EP) election 2019 in Germany was exceptional for several reasons. Most notably, Bündnis90/Die Grünen (the Green Party) nearly doubled its support compared with the EP election in 2014, while the CDU/CSU (Christian Union) and SPD (Social Democrats) had their worst results in the history of EP elections. Another characteristi...

This study examines the relationship between residential segregation and social trust of immigrants and natives in the Netherlands. Building on previous studies that have found evidence for a negative segregation-trust link, we present a nuanced narrative by (i) distinguishing between an ethnic minority and majority perspective, (ii) elaborating th...

Communities provide a crucial experiential context for native-immigrant interactions, yet we know little about the impact of local government performance on shaping public responses to immigrants. Building on arguments considering efficient governments as critical factors in facilitating immigrant integration and mitigating denizens’ political depr...

Article
Previous research suggests that individual-level factors such as socio-economic disadvantage and discrimination account for lower levels of generalized social trust of immigrants when compared to natives. This study examines how individual and contextual economic conditions impact such trust gaps. We argue that—beyond objective economic circumstanc...
Article
This study investigates how antidiscrimination policy and related policy knowledge influence citizens’ support for the democratic system and its institutions. The article argues that antidiscrimination measures and knowledge about rights to equal treatment foster perceptions of government responsiveness, which increase political support among targe...
Article

Public policies addressing societal problems typically aim to change citizens’ behaviors and attitudes. While scholars frequently link cross-national differences in specific policies with individuals’ attitudinal or behavioral outcomes, the specific operating mechanisms often remain veiled. The policy feedback literature provides an explanatory fra...

This study investigates how personality relates to citizens’ willingness to extend political, social, and cultural rights for minorities, including voting rights for immigrants, religious rights for Muslims, and affirmative action measures. Moving beyond explanations centred on intergroup relations, we argue that political efficacy (i.e. beliefs ab...
Article
Europe faces the challenge of enormous recent asylum seeker inflows, and the allocation of these immigrants across European countries remains severely skewed, with some countries having a much larger per capita share of asylum applicants than others. Consequently, there is a debate at the EU level on how to allocate asylum seekers in order to tackle...
Article
This study examines whether the values prevalent in one's social environment moderate the link between immigration-related ethnic diversity and social trust. Drawing on arguments related to intergroup relations and anomie, we expect that contexts characterized by a comparatively high degree of openness mitigate a trust-eroding effect of immigration...

In an era of mass migration, social scientists, populist parties and social movements raise concerns over the future of immigration-destination societies. What impacts does this have on policy and social solidarity? Comparative cross-national research, relying mostly on secondary data, has findings in different directions. There is a threat of sele...

Immigrants and ethnic minority members typically hold lower levels of social trust than majority members due to fewer socio-economic resources and a higher risk of discrimination. While institutional factors are a strong predictor for different levels of social trust across countries, we know little about whether and how institutional and political...

In this study, we examine the role of social trust as an individual and a neighborhood-level determinant for radical right-wing populist party preferences. We argue that high social trust decreases radical right-wing populist party preferences and that this relationship is essentially mediated by negative attitudes toward immigrants. Using data fro...

Contrasting “the pure people” with “the corrupt elite” is a prominent rhetorical figure of populist radical right parties and their proponents. However, scholars rarely consider political corruption as an explanatory factor for the electoral success of this party family. This study investigates the role of individual corruption experience in dealin...

Generalized social trust is a central research topic in the social sciences, not least because it is associated with a number of positive societal outcomes. Immigrants and members of ethnic minorities typically hold lower levels of social trust than majority members because they possess fewer socioeconomic resources and have a higher risk of being discriminated against. Previous research on group-related trust differences has largely focused on individual factors as explanatory factors. Questions related to contextual explanatory factors as well as the implications of group-related trust differences for the integration of immigrants have not been systematically addressed so far. The proposed project examines social trust of immigrants in Europe and particularly focuses on group-related trust differences between the majority populations and immigrants, henceforth referred to as interethnic trust asymmetries. The following two research questions guide the investigation: 1. To what extent affect economic conditions and residential ethnic segregation interethnic trust differences? 2. How do interethnic trust asymmetries affect integration outcomes of immigrants as well as intergroup relations? As data sources, the project uses available survey data from the European Social Survey (ESS 2002-2014) and the Netherlands Longitudinal Lifecourse Study (NELLS, 2009 and 2013). The survey data will be combined with local and regional macro data and analyzed employing regression analysis, in particular multilevel analysis. The results highlight causes and consequences of group-related differences in social trust, which, in addition to a contribution to the integration literature, also yields social and political relevance.
