  abstract  = {Emerging evidence has highlighted the important role of local contexts for integration trajectories of asylum seekers and refugees. Germany's policy of randomly allocating asylum seekers across Germany may advantage some and disadvantage others in terms of opportunities for equal participation in society. This study explores the question whether asylum seekers that have been allocated to rural areas experience disadvantages in terms of language acquisition compared to those allocated to urban areas. We derive testable assumptions using a Directed Acyclic Graph (DAG) which are then tested using large-N survey data (IAB-BAMF-SOEP refugee survey). We find that living in a rural area has no negative total effect on language skills. Further the findings suggest that the "null effect" is the result of two processes which offset each other: while asylum seekers in rural areas have slightly lower access for formal, federally organized language courses, they have more regular exposure to German speakers.},

  abstract  = {Permanent income (PI) is an enduring concept in the social sciences and is highly relevant to the study of inequality. Nevertheless, there has been insufficient progress in measuring PI. We calculate a novel measure of PI with the German Socio-Economic Panel (SOEP) and U.S. Panel Study of Income Dynamics (PSID). Advancing beyond prior approaches, we define PI as the logged average of 20+ years of post-tax and post-transfer ("post-fisc") real equivalized household income. We then assess how well various household- and individual-based measures of economic resources proxy PI. In both datasets, post-fisc household income is the best proxy. One random year of post-fisc household income explains about half of the variation in PI, and 2-5 years explain the vast majority of the variation. One year of post-fisc HH income even predicts PI better than 20+ years of individual labor market earnings or long-term net worth. By contrast, earnings, wealth, occupation, and class are weaker and less cross-nationally reliable proxies for PI. We also present strategies for proxying PI when HH post-fisc income data are unavailable, and show how post-fisc HH income proxies PI over the life cycle. In sum, we develop a novel approach to PI, systematically assess proxies for PI, and inform the measurement of economic resources more generally.},

These factors, along with an increased awareness of the pitfalls of the nonequivalent comparison group design for the estimation of causal effects, have moved the attention of applied researchers away from issues of sampling and toward issues of identification. This article discusses the usability of samples with unknown selection probabilities for various research questions. In doing so, we review assumptions necessary for descriptive and causal inference and discuss research strategies developed to overcome sampling limitations.},

  abstract  = {Obwohl Latein eine nicht mehr gesprochene Sprache ist und ihr deswegen kein kommunikativer Nutzen zukommt, ist die Anzahl der Latein als Schulfach w{\"a}hlenden Sch{\"u}ler im Zeitverlauf angestiegen. Mehrere Studien haben zudem gezeigt, dass Lateinkenntnisse weder das logische Denken, noch den Erwerb anderer Sprachen, noch das Gesp{\"u}r f{\"u}r die grammatikalische Struktur der Muttersprache verbessern. Auch wenn sich empirisch keine Vorteile des Erwerbs alter Sprachen nachweisen lassen, k{\"o}nnen Menschen subjektiv an solche Vorteile glauben und ihr Verhalten an ihrer Konstruktion von Wirklichkeit ausrichten. Auf der Basis einer unter Eltern von Gymnasialsch{\"u}lern durchgef{\"u}hrten Befragung zeigen wir, dass Latein umfassende Transfereffekte zugeschrieben und Personen mit Lateinkenntnissen positiver bewertet werden als Personen mit Kenntnissen moderner Sprachen. Weiterhin zeigt sich, dass die „Illusio" der Vorteile von Latein zwar in allen Bildungsgruppen wirksam ist, doch besonders von den Hochgebildeten vertreten wird. Sie arbeiten damit an der Konstruktion einer Realit{\"a}t, von der sie selbst die gr{\"o}ßten Nutznießer sind, indem sie Latein als symbolisches Kapital verwenden.},
