The Challenges of Spatial and Temporal Aggregation: Modelling Issues, Applications, and Policy Implications: Editorial

Does Subsidized Care for Toddlers Increase Maternal Labor Supply?

Expanding public or publicly subsidized childcare has been a top social policy priority in many industrialized countries. It is supposed to increase fertility, promote children’s development and enhance mothers’ labor market attachment. In this paper, we analyze the causal effect of one of the largest expansions of subsidized childcare for children up to three years among industrialized countries on ...

Early Education and Care Quality: Does It Matter for Maternal Working Hours?

This study investigates whether mothers whose children enter early childhood education and care (ECEC) centers of higher quality are more likely to work longer hours. The empirical analysis links the Socio-Economic Panel (SOEP) Study with the K2iD-SOEP extension study, which collected ECEC quality information from childcare centers across Germany. Based on a sample of 556 mothers of 628 children with ...

Family Separation and Refugee Mental Health: a Network Perspective

How do the structure and relational features of family networks affect refugees’ mental health after migration, particularly when refugees are geographically separated from their family? Using the first wave of the IAB-BAMF-SOEP Survey of Refugees, which is representative of the population of refugees who arrived in Germany between 2013 and 2016, this study finds that the size of the nuclear family ...

Labor Market and Distributional Effects of an Increase in the Retirement Age

We evaluate the labor market and distributional effects of an increase in the early retirement age (ERA) from 60 to 63 for women born after 1951. We use a regression discontinuity design which exploits the strong increase in the ERA between women born in 1951 and 1952. The analysis is based on the German microcensus which includes about 370,000 households per year. We focus on heterogeneous labor market ...

The Political Economy of Coal in Poland: Drivers and Barriers for a Shift away from Fossil Fuels

Poland is the largest hard coal and second largest lignite producer in the EU, generating around 80 percent of its electricity from coal. Resistance to a reduction in coal production and consumption comes from various actors, namely, coal corporations, unions, parts of civil society and the government – as well as their coalitions. Their opposition centres around the prospect of losing their business, ...

Dieser Beitrag richtet sich auf die Frage, inwieweit Roboter in der Pflege heute von der erwachsenen Bevölkerung in Deutschland akzeptiert werden. Und inwieweit beeinflussen Geschlecht, Alter und Erfahrung (beruflich, ...

How People Know Their Risk Preference

People differ in their willingness to take risks. Recent work found that revealed preference tasks (e.g., laboratory lotteries)—a dominant class of measures—are outperformed by survey-based stated preferences, which are more stable and predict real-world risk taking across different domains. How can stated preferences, often criticised as inconsequential “cheap talk,” be more valid and predictive ...

Depression, Neuroticism and 2D:4D Ratio: Evidence from a Large, Representative Sample

A body of literature reports higher rates of depression and neuroticism in female samples compared to male samples. Numerous studies have investigated the role of prenatal sex hormone exposure in this sex difference, using the ratio between the second and fourth digit of the hand (“2D:4D”) as a putative marker. However, the sample sizes of those studies were mostly small and results remained inconclusive. ...
