Der Beitrag illustriert Konstruktionsprinzipien, Potenziale und Fallstricke von Vignettenexperimenten anhand eines faktoriellen Surveyexperiments zur Bedeutung soziodemografscher und meritokratischer Merkmale beim Zugang zur Professur. Im Rahmen des Surveyexperiments wurden alle Universitätsprofessor*innen der Germanistik, Soziologie, Politikwissenschaft, Geographie und Chemie in Deutschland eingeladen, Vignettenprofile hypothetischer Wissenschaftler*innen auf ihre Eignung für unbefristete Professuren hin zu beurteilen. Anhand dieser Beispielanwendung veranschaulicht der Beitrag die Möglichkeiten und Grenzen von Vignettenexperimenten mit Blick auf die Validität der erzielten Ergebnisse.

In many Western countries, women are more likely to study abroad than men. At present, there is a lack of theory-guided empirical studies searching explanations for this pattern. We address this research gap by examining gender differences in study abroad intent among first-semester students in Germany. To derive a comprehensive theoretical framework, we draw on social role theory of sex differences, cognitive development theory, new home economics and statistical discrimination theory. Using data from the nationally representative 2010 DZHW School Leavers Survey, we test our hypotheses by estimating logistic regressions and non-linear effect decompositions.

This editorial to the special issue on heterogeneous effects of studying abroad starts with a review of studies on the determinants and individual-level effects of studying abroad. On that basis, it illustrates the necessity to place more emphasis on effect heterogeneity in research on international student mobility. It then develops a typology of heterogeneous effects of studying abroad, which shall function as an agenda for future research in the field. Thereafter, the editorial introduces the contributions to the special issue. It concludes by summarising major findings and directions for future research.

Studying abroad can positively influence students’ personality development, transversal skills, and labour market outcomes. At the same time, students from a high social origin are more likely to study abroad than students from a low social origin. Against this background, recent research has suggested that international student mobility (ISM) may foster the reproduction of social inequality. However, this assumption has hardly been tested empirically. Drawing on social stratification theory, we first demonstrate that a scenario in which ISM increases social inequality (cumulative advantage) is as plausible as a scenario in which it decreases social inequality (compensatory levelling).

In this article, we review quantitative studies that empirically examine whether studying abroad influences graduates’ wages. Our review suggests that studying abroad has a moderate positive effect on graduates’ early-career wages in various national and institutional settings. However, this effect tends to vary across groups of graduates, employment contexts, and types of stays abroad. Employer change, access to large and multinational companies, and access to high-wage labor markets abroad appear to be the most relevant mechanisms mediating the effect of studying abroad on wages. Other mechanisms, such as improved language skills and a greater tendency to pursue further education, turn out to be less relevant.

In einem systematischen Review werten Nicolai Netz, Svenja Hampel und Valeria Aman 96 empirische Studien zum Einfluss internationaler Mobilität auf wissenschaftliche Karrieren aus. Die Analyse dieses noch jungen, aber in den letzten Jahren sehr dynamischen Forschungsfeldes zeigt, dass internationale Mobilität zum Ausbau wissenschaftlicher Netzwerke beiträgt. Zudem gibt es Hinweise, dass internationale Mobilität die wissenschaftliche Produktivität und Rezeption, das heißt die Anzahl der Publikationen und Zitationen, erhöhen kann. Auch den beruflichen Aufstieg kann internationale Mobilität begünstigen. Sie scheint jedoch ebenso mit durchschnittlich längeren befristeten Beschäftigungsverhältnissen einherzugehen.

Using theories of social inequality and migration, we combine the research strands dealing with study-related international mobility and with migration-related inequalities in higher education. Based on data from the 20th German Social Survey, we examine mechanisms through which a migration background may influence whether students in Germany intend to study abroad. Logistic regressions show that students with a migration background tend to be disadvantaged regarding their social background, which reduces their likelihood of intending to study in a different country.

The internationalization and specialization of science confront scientists with opportunities and sometimes even a need to become internationally mobile during their careers. Against this background, we systematically reviewed empirical studies on the effects that mobility across national borders has on the careers of scientists. Using several search channels, we identified 96 studies – published between 1994 and 2019 – that examine how international mobility influences eight dimensions of scientists’ careers.

In recent years, the body of evidence suggesting that studying abroad during higher education can positively influence students’ personality development, academic knowledge and skills, intercultural competences, and employment prospects has increased. Policy makers and scholars alike want to understand who reaps these benefits and who does not. Hence, we review studies examining how key socio-demographic variables (gender, age, socio-economic background, and ethnicity) influence the likelihood of studying abroad.

Im Rahmen des Projekts wurde untersucht, welche Faktoren beeinflussen, ob Wissenschaftler*innen international mobil werden, und welche Effekte internationale Mobilität auf die Karrieren von Wissenschaftler*innen hat. Es wurde ebenfalls thematisiert, inwiefern mögliche berufliche Effekte internationaler Mobilität spezifisch für physische grenzüberschreitende Mobilität bzw. durch Formen virtueller Mobilität substituierbar sind.

Die Studie untersucht auf Basis des Promoviertenpanels des Deutschen Zentrums für Hochschul- und Wissenschaftsforschung (DZHW), inwiefern sich die Wahrscheinlichkeit von Auslandsaufenthalten nach Promotionskontexten unterscheidet. Promovierende in strukturierten Programmen (33%) und Stipendienprogrammen (30%) gehen deutlich häufiger ins Ausland als Promovierende auf Haushalts- (18%) und Drittmittelstellen (14%) sowie frei Promovierende (6%). Logistischen Regressionen zufolge erklärt sich dies teils durch individuelle Selektion in Promotionskontexte, insbesondere in Abhängigkeit der studienbezogenen Auslandserfahrung und des Promotionsfachs.
