The Effect of Increasing Retirement Age on Households’ Savings and Consumption Expenditure

This paper examines how households adjust their savings and consumption expenditure in response to an anticipated increase in the early retirement age (ERA). We examine the 1999 pension reform in Germany, which increased the ERA for women born after 1951 by at least three years. First, we present suggestive evidence that women update their retirement planning in response to the reform. Using the German ...

Information Provision and Postgraduate Studies

This is the first paper to examine experimentally effects of information provision on beliefs about pecuniary and non-pecuniary returns of postgraduate education, enrolment intentions and realized enrolment. We find that our treatment causally affects beliefs measured six months after treatment. The effects on beliefs differ by gender and academic background, and we find that stated enrolment intentions ...

Observing Many Researchers Using the Same Data and Hypothesis Reveals a Hidden Universe of Uncertainty

This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions ...

Attitudes Toward Mandatory COVID-19 Vaccination in Germany: A Representative Analysis of Data from the Socio-economic Panel for the Year 2021

Adequate immunity to COVID-19 apparently cannot be attained in Germany by voluntary vaccination alone, and therefore the introduction of mandatory COVID-19 vaccination is still under consideration. We present findings on the potential acceptance of such a requirement by the German population, and we report on the reasons given for accepting or rejecting it and how these reasons vary according to population ...

Mentoring as a Grassroots Effort for Integrating Refugees – Evidence from a Randomised Field Experiment

About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to support refugee integration in hosting communities. This study examines a network intervention for refugees in collaboration with a social start-up whose mission is to match refugees and local volunteers to form friendships. We apply ...

Impact of the COVID‑19 Pandemic on Depression, Anxiety, Loneliness, and Satisfaction in the German General Population: a Longitudinal Analysis

Purpose Cross-sectional studies found high levels of depression and anxiety symptoms, and loneliness during the first wave of the COVID-19 pandemic. Reported increases were lower in longitudinal population-based findings. Studies including positive outcomes are rare. This study analyzed changes in mental health symptoms, loneliness, and satisfaction. Methods Respondents of the German Socio-Economic ...

Fact Boxes that Inform Individual Decisions May Contribute to a More Positive Evaluation of COVID-19 Vaccinations at the Population Level

ObjectiveFor an effective control of the SARS-CoV-2 pandemic with vaccines, most people in a population need to be vaccinated. It is thus important to know how to inform the public with reference to individual preferences–while also acknowledging the societal preference to encourage vaccinations. According to the health care standard of informed decision-making, a comparison of the benefits and harms ...

Carbon Contracts-for-difference: How to De-risk Innovative Investments for a Low-carbon Industry?

The shift to climate neutrality requires new process technologies for energy-intensive industries, such as steel, chemicals, or cement. A variety of technology options exist – but they face the challenges of (i) first-of-kind costs, (ii) higher operation and investment costs, and (iii) insufficient and uncertain carbon prices, which partly stem from political uncertainty. Existing innovation policy ...

The Expansion of Natural Gas Infrastructure Puts Energy Transitions at Risk

Whether additional natural gas infrastructure is needed or would be detrimental to achieving climate protection goals is currently highly controversial. Here we combine five perspectives to argue why expansion of the natural gas infrastructure hinders a renewable energy future and is no bridge technology. We highlight that natural gas is a fossil fuel with a significantly underestimated climate impact ...
