Using longitudinal data from the IAB-BAMF-SOEP Refugee Survey and the IAB-BiB/FReDA-BAMF-SOEP Ukrainian Refugee Survey, we trace labour-force participation (LFP) and employment rates during the first three ...

Focusing on the resilience of corporate R&D activities, we explore two dimensions: stability and adaptability. Using two large datasets on the world’s leading R&D-investing companies covering the periods 2004–2010 and 2015–2021, thus including both crises, our analysis ...

Ziel ist es daher, das Vorliegen einer depressiven (DS) und Angstsymptomatik (AS) bei geflüchteten Menschen aus der Ukraine zu beschreiben, relevante Einflussfaktoren zu identifizieren und die Prävalenzen psychischer Belastungen mit anderen Herkunftsgruppen zu vergleichen. ...

An influential survey by Joshua Knobe (2003) indicates that the cognitive process ascribing intentionality to an agent is mediated by the perceived moral worth of the action. To assess the external validity of the finding and to obtain more precise estimates of effect sizes, the present study replicates this canonical experiment with a large scale random sample of the German population (N = 2,295). ...

Despite the rise in global refugee migration, probability panels surveying refugees remain rare. The German IAB-BAMF-SOEP Survey of Refugees, conducted annually since 2016, provides valuable panel data for research. In 2023, following Russia’s invasion of Ukraine, a sample of Ukrainian refugees was added, along with a refreshment sample of refugees from other countries. This paper examines household-, ...

Objectives Cumulative advantage is a central concept in life course research. Prior research has primarily focused on one outcome domain, overlooking the possibility that cumulative advantage could extend into other domains–what we refer to as diffusion of cumulative advantage. We build on and extend cumulative inequality theory to conceptualize diffusion and apply it to wealth and health, two domains ...

Deutschlands massiv steigende Verteidigungsausgaben wären effizienter eingesetzt, wenn die Rüstungsgüter innerhalb Europas stärker vereinheitlicht würden. Eine EU-weite Lösung scheint derzeit unrealistisch. Abkommen für einzelne Produkte, wie Kampfflugzeuge, bleiben zwar wichtig, aber punktuell. Eine Zwischenlösung könnte die enge Kooperation einiger Länder sein, um die Beschaffung und Produktion von ...

This paper introduces the Open Data Format (ODF), a non-proprietary, metadata-enriched, and zipcompressed data format for tabular data alongside statistical software packages. It embeds structured, multilingual metadata directly within the data file, using the well-established DDI-Codebook standard (DDI Alliance, 2014), and enables access to both data and documentation within common statistical environments. ...

Angesichts von Arbeitskräfteengpässen wird häufig gefordert, die Erwerbstätigkeit von Frauen weiter zu stärken. Gleichzeitig arbeiten insbesondere Mütter häufig weniger, als sie möchten, was darauf hindeutet, dass Betreuungsverpflichtungen die Realisierung des gewünschten Erwerbsarbeitsumfangs verhindern. Ein Baustein zur Lösung dieses Vereinbarkeitsproblems könnte mehr Flexibilität im Sinne der Beschäftigten ...

The present research examines whether and how well-documented historical changes in resource availability, social embedding, technology, and social norms also manifest in control beliefs—a key psychological marker of individual health and well-being. Drawing on longitudinal data from five waves of the German Socio-Economic Panel (N = 42,158) spanning over 20 years, we analyzed control belief trajectories ...

Germany is tasked with ensuring the safe and final storage of high-level radioactive waste in a deep geological repository. Since 2022, the ambitious target year of 2031 to identify a suitable location for such a site has been deferred by most public actors. The target year was pushed back by several decades to 2046 or even 2068, consequently delaying the completion of all waste management activities ...

This study investigates whether having daughters impacts political preferences and whether this effect varies across European countries. We estimate effect sizes for 39 countries in the European Social Survey (n = 156,236) and aggregate estimates using random-effects meta-analysis, following a preregistered analysis plan. We find significant evidence that having daughters increases the preference for ...

To ensure security of supply in the power sector, many countries are considering capacity mechanisms. Simultaneously, the expansion of variable renewables increases the need for power sector flexibility, with promising options on the demand side. We analyze how a centralized capacity market and an advanced reliability reserve with a moderately high activation price affect demand-side flexibility investments ...

Housing markets are affected by a wide variety of factors. Among them, governmental regulations play an important role. Besides desired effects, all these policies exert a number of side effects, even offsetting the desired effects. In addition, different policies can cancel out each other. Therefore, it is important to be aware of the effects of individual policies and the composite effects resulting ...

We study the role of international financial integration in buffering natural disaster shocks, using a large sample of advanced and emerging economies. Natural disasters are largely unpredictable and unrelated to the state of financial integration. We document that integration improves the absorption of such shocks: Output, consumption, and investment are significantly higher after a natural disaster ...

BACKGROUND Parenting leave policies shape how caregiving and paid work can be reconciled around the time of childbirth. They have important implications for fertility, employment, and gender equality. Still, there are limited quantitative cross-country data capturing longterm policy changes that impact how long parents can temporarily be away from work to care for their children, and how leave can ...

This study examines the payout policies of modern state-owned enterprises (SOEs) using unique official statistics on German SOEs from 2003 to 2014. The findings reveal that agency conflicts significantly influence SOEs’ payout behavior, leading to payout smoothing over time. Vertical agency costs, arising from owner-manager conflicts, and horizontal agency costs, stemming from owner-owner conflicts, ...

The European Carbon Border Adjustment Mechanism (CBAM) has the dual objective of preventing carbon leakage and encouraging adoption of low-carbon tech-nologies abroad. Yet, pursuing both objectives with the same mechanism results in incomplete carbon leakage protection unless global carbon prices converge. As the current geopolitical situation makes rapid convergence seem unlikely, an extension of ...
