Buyer Power and the Effect of Vertical Integration on Innovation

Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer(s) and the retailer bargain over nonlinear contracts before selling to consumers. We show that vertical integration always increases the incentives to ...

The Early Bird Gets the Germs? The Impact of Early Daycare Attendance on Children’s Health

In recent decades, the share of very young children in daycare has significantly increased in many OECD countries, including Germany. Despite the critical role of child health in development and later life success, the impact of early daycare attendance on health has received little attention in the economic literature. This study examines the effects of a substantial daycare expansion in Germany on ...

Split Between Accelerationists, Pivoters, and the Unwavering: CEE Energy Policy Responses to Russia’s 2022 Invasion

Dynamic Networks of Social Contact, Social Desire, and Affect Across Time Scales

Social relationships are central to well-being because they fulfill social affiliation needs. To explain how social needs are regulated, theories describe daily-life processes among social desire, social contact, and affect. Still, these processes remain empirically underexplored because of their complexity. In this study, we estimated multivariate associations of social desire and affect with social ...

The Distribution of National Income in Germany, 1992–2019

This paper estimates and analyzes the distribution and composition of pre-tax national income in Germany since reunification, combining personal income tax returns, household survey data, and national accounts. We find that pre-tax national income inequality has increased since the 1990s, though to a lesser extent than suggested by previous studies. Our results draw parallels in top income structure ...

Utilisation of Reactive Ionic Liquids for Energy Storage and Regulation of the Power Grid

Chlorine is an essential feedstock for polymers and pharmaceuticals, with annual production exceeding 100 Mt. Nearly all Cl2 is obtained by chlor–alkali electrolysis, which consumes about 2.58 MWh of electricity per tonne. Renewable energies such as wind and solar would lower CO2 emissions, but electrolysers would then have to adopt to fluctuating, renewable energies while downstream processes still ...

Pre- and Post-Migration Determinants of Self-Rated Health Among Ukrainian Refugees In Germany: A Cross-Sectional Comparative Analysis with Recently Arrived Refugees from Other Countries of Origin

However, little is known about the differences in health determinants for individuals arriving under the EU Temporary ...

Who Is AI Replacing? The Impact of Generative AI on Online Freelancing Platforms

This paper studies the impact of generative artificial intelligence (AI) technologies on the demand for online freelancers using a large data set from a leading global freelancing platform. We identify the types of jobs that are more affected by generative AI and quantify the magnitude of the heterogeneous impact. Our findings indicate a 21% decrease in the number of job posts for automation-prone ...

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 ...

Information sources such as interpersonal sources, traditional print and digital media as well as social media offer information about the risks and benefits of vaccination. During health crises such as the COVID-19 pandemic was, some information sources provide hanging ...
