This paper outlines two studies on education bias in German probability-based surveys. Study 1 reviews data from 67 surveys across 19 survey programs conducted in Germany from 2000 to 2023. We found a consistent underrepresentation of individuals with a low level of formal education. We also found that the transition to self-administered modes due to rising survey costs may exacerbate this bias in ...

Background Populations experiencing precarity face heightened mental health inequities, especially during crises. In this regard, it is established that socio-economic status (SES) and social isolation are critical factors influencing mental health outcomes, which interact syndemically. Understanding their interrelated mechanisms is crucial for developing effective public health strategies to support ...

The current work relies on G-SOEP to study the effects of import competition on fertility choices. This phenomenon has been addressed by using a single-observation dataset following the seminal paper of Autor et al. (2014). The results show a negative and significant effect on the choice of childbearing.Moreover, the trade exposure measure has been computed by aggregating the Lander and, in a second ...

This article compares the promotion prospects of East Germans in leadership and elite positions. It starts from the observation that East Germans have lower chances of reaching leadership positions, although these have converged with those of West Germans in younger birth cohorts. Theoretical considerations on the distinction between leadership and elite positions, along with empirical findings based ...

Social science research gives rise to what we call the ?refugee mobility puzzle?: While restrictions on the freedom of residence limit refugees? socio-economic integration, those who do not face such restrictions often move to areas with high unemployment that similarly hinder their labor market prospects. This study addresses a central element of this puzzle: What draws refugees to high unemployment ...

Data quality is known to be compromised when respondents cognitively shortcut the survey response process. This satisficing behavior leads to inaccurate and unreliable responses that are hard to compensate after data collection. Thus, detecting and understanding surrvey satisficing is crucial for developing and implementing effective preventive measures in longitudinal data collection contexts. We ...

The integration chances of refugees in their host country are critically shaped by the contextual conditions of the location to which they are assigned upon arrival. Several research groups have developed algorithmic tools to optimize refugee-location matching, with the overall aim of improving refugees’ integration outcomes. These tools are used in a highly sensitive context and thus their design, ...

The new German federal government coalition is planning a significant tax break for workers of retirement age: the active pension (Aktivrente). With the active pension, workers who have reached the statutory retirement age may earn up to 2,000 euros a month tax-free, a move that the government is hoping will motivate more pensioners to work longer to counteract the skilled worker shortage. Microsimulation ...

Motivated by research on gender identity norms and the distribution of the woman’s share in a couple’s total labor income, we consider additive regression models for densities as responses with scalar covariates. To preserve nonnegativity and integration to one under vector space operations, we formulate the model for densities in a Bayes Hilbert space, which allows to not only consider continuous ...

Objective: This study aimed to examine the curvilinear relationship between screen time and mental health in childhood and adolescence—thereby testing the digital Goldilocks hypothesis (Przybylski & Weinstein, 2017). Methods: Multiple data sweeps were utilised from the Millennium Cohort Study, a nationally representative longitudinal study of children born in the UK in 2000-2002. Mental health ...
