Perceived Discrimination Among Migrants in Germany: Does Social Capital Moderate Harmful Effects on Mental Health?

Background The harmful mental health effects of perceived discrimination for migrant populations are well established. The potential buffering effect of regional-level social capital, however, has not previously been explored. Methods Using data from the German Socio-Economic Panel (SOEP; 2009–2018) we apply multilevel models to assess the effect of frequent or infrequent perceived discrimination on ...

Inform Me When It Matters: Cost Salience, Energy Consumption, and Efficiency Investments

Using a large-scale natural experiment in staggered billing dates for energy use in Germany and a unique billing dataset for multi-apartment buildings, this paper shows that the month of billing is a significant determinant of heat energy consumption. A large set of residential buildings demand significantly more heat energy annually, when the bill is issued during off-winter months. The paper finds ...

Age and Cognitive Skills: Use It or Lose It

Cross-sectional age-skill profiles suggest that cognitive skills start declining by age 30 if not earlier. If accurate, such age-driven skill losses pose a major threat to the human capital of societies with rapidly aging populations. We estimate actual age-skill profiles from individual changes in literacy and numeracy skills at different ages. We use the unique German longitudinal component of the ...

Does Perceived Social Cohesion Moderate the Effect of Parental Stressors on Depressive Symptoms? A Longitudinal, Multi-Level Analysis Before and During the COVID-19 Pandemic

Background Perceived social cohesion (PSC) is a protective factor for mental health. Yet, evidence on social mechanisms influencing mental health is scarce. Aims We examined the moderating role of PSC between parental stressors and depressive symptoms before and during the COVID-19 pandemic. Methods We performed a multilevel moderated linear regression analysis using German Socio-Economic Panel ...

Integrating Renewable Energy Resources in Electricity Distribution Systems—a Firm-Level Efficiency Analysis for Sweden Controlling for Weather Conditions

Sweden is at the forefront of the transition of its energy sector to low-carbon technologies with profound consequences for both energy generation and its distribution. However, the impact of this transition on the performance of Electricity Distribution System Operators (DSOs) has not been thoroughly studied. The article addresses this gap by using a novel approach and detailed georeferenced firm-level, ...

Is Russian Gas Still Needed in the European Union? Model-Based Analysis of Long-Term Scenarios

Aligned with the war in Ukraine, Russia has significantly withheld natural gas exports to Europe since 2021. As there are no EU-wide sanctions on imports of Russian natural gas, the Ukraine transit as well as imports via Turkey and LNG have remained active during 2022–24. However, the Russian-Ukrainian transit agreement expires at the end of 2024 and discussions about new sanctions on natural gas as ...

Let’s Switch to the Cloud: Cloud Usage and Its Effect on Labor Productivity

The advent of cloud computing promises to improve the way firms use IT solutions. Firms are expected to replace large and inflexible fixed-cost investments in IT with more targeted, variable spending on cloud solutions. This is also expected to increase firms' productivity by allowing them to quickly adapt their IT infrastructure to their specific needs. We assess this claim using firm-level data provided ...

For the period after 1990, we analyse the entire distributionsfrom top ...

Grüne Transformation in Deutschland – nur mit echter Energiewende ein ökologischer und ökonomischer Erfolg

In order to achieve climate targets, a comprehensive energy transition is necessary in which nearly all energy comes from renewable sources. The switch to renewable energies is not only of enormous strategic importance in terms of climate protection. In combination with the technological innovations it triggers, renewable energy also creates the scope for climate-neutral growth.

The Reputation Effect of Repeated Green-Bond Issuance and Its Impact on the Cost of Capital
