Kumulation von Mikrodaten – Konzeptionelle Grundlagen und ein Vorschlag zur Realisierung

Zusammenfassung: In dieser Studie wird ein Konzept zur Kumulation von laufenden Haushaltsbudgetbefragungen im Rahmen des Projektes Amtliche Statistik und sozioökonomische Fragestellungen entwickelt und zur Diskussion gestellt. Dafür werden die theoretischen Grundlagen und Bausteine gelegt und die zentrale Aufgabe einer strukturellen demographischen Gewichtung mit einem Hochrechnungs–/Kalibrierungsansatz auf informationstheoretischer Basis gelöst.Vor dem Hintergrund der Wirtschaftsrechnungen des Statistischen Bundesamtes (Lfd. Wirtschaftsrechnungen und EVS) wird darauf aufbauend ein konkretes Konzept für die Kumulation von jährlichen Haushaltsbudgetbefragungen vorgeschlagen. Damit kann das Ziel einer Kumulation von Querschnitten mit einer umfassenderen Kumulationsstichprobe für tief gegliederte Analysen erreicht werden. Folgen sollen die Simulationsrechnungen zur Evaluation des Konzepts.

Summary: In this study a concept for cumulating periodic household surveys within the frame of the project Official Statistics and Socio–Economic Questions is developed and asks for discussion. We develop the theoretical background and solve the central task of a structural demographic weighting/calibration based on an information theoretical approach.Based on the household budget surveys of the Federal Statistical Office (Periodic Household Budget Surveys and Income and Consumption Sample (EVS)) a practical concept is proposed to cumulate yearly household surveys. This allows a cumulation of cross–sections by a comprehensive cumulated sample for deeply structured analyses. In a following study this concept shall be evaluated.

     

Did the escalation of the financial crisis of 2008 affect the perception of immigration-related threats? A natural experiment

In this paper, we apply a natural experiment approach, comparing specific data from the European Values Study prior to and after the escalation of the financial crisis in 2008. The aim is to disentangle the short-term effect of the crisis on the relationship between social vulnerability and immigrant-related threat perceptions for the residents of Luxembourg (natives and foreign nationals). Propensity score matching is used to ensure the balanced composition of the control group and treated group with regard to the observed covariates. The results reveal that vulnerable foreign nationals demonstrated lower perceptions of immigration-related threats after the escalation of the crisis than their pre-crisis counterparts. No significant effect of the escalation of the crisis was found among Luxembourg nationals.     

Attitudes toward immigrants in Luxembourg. Do contacts matter?

The number of immigrants in Luxembourg is approaching the number of native-born population. This demographic change raises questions concerning social inclusion, social cohesion, and intergroup conflicts. The present paper contributes to this discussion by analyzing attitudes toward immigrants and their determinants. Controlling for key individual characteristics, we examine how the intensity of core contacts between nationals and inhabitants with migratory background affects attitudes toward immigrants among three groups of Luxembourg residents: natives, first-generation immigrants, and second-generation immigrants. The results indicate that attitudes toward immigrants depend significantly on the origins of the residents of Luxembourg. Natives adopt the most negative stance toward immigrants; they are followed by second-generation and first-generation immigrants. Attitudes of second-generation immigrants are closer to those of the native population than to those of first-generation immigrants. Core contacts appear to play the most important role in the case of first-generation immigrants. The more connected the first-generation migrant to the native population, the more negative his/her opinion of immigrants.
