Online panel surveys are often criticized for their inability to cover the offline population, potentially resulting in coverage error. Previous research has demonstrated that non-internet users in fact differ from online individuals on several sociodemographic characteristics. In attempts to reduce coverage error due to missing the offline population, several probability-based online panels equip ...

Investigating wellbeing development and its predictors is crucial to understand how individuals adapt to chronic illnesses. This study (i) analyzed the impact of a chronic disease on wellbeing development, and (ii) explored spatial healthcare access as potential moderating factor. ...
In this study, we argue that parents’ class position may influence the type and timing of their offspring's investments in financial assets. These investments may facilitate net worth accumulation beyond direct transfers, contributing to the intergenerational reproduction of social positions. We test these expectations using retrospective life history and prospective panel data for 14 countries from ...
The number of women serving on the executive boards of large companies in Germany once again increased in 2023: Around 18 percent (153 of 875) of executive board members at the 200 largest companies were women as of late fall 2023, two percentage points higher than in 2022. Thus, growth has slightly picked up again. In some of the groups of companies analyzed, the figure was even higher. Around 23 ...
We analyse variation in firm performance as a function of the international diversification of ICT imports by firms. Drawing on administrative data from 2010 and 2014 on nearly 4000 German manufacturing firms, we find that firms with ICT sourcing that is diversified across multiple countries perform better than similar, less-diversified firms. This finding holds true for two performance metrics (value ...

While inequality of opportunity (IOp) in earnings is well studied, the literature on IOp in individual net wealth is scarce to non-existent. This is problematic because both theoretical and empirical evidence show that the position in the wealth and income distribution can significantly diverge. We measure ex-ante IOp in net wealth for Germany using data from the Socio-Economic Panel (SOEP). Ex-ante ...
