Poor Glucose Regulation is Associated with Declines in Well-Being among Older Men, but not Women

Glucose regulation is a key aspect of healthy aging and has been linked to brainfunctioning and cognition. Here, we examined the role of glucose regulation for withinpersonlongitudinal trajectories of well-being. We applied growth models to data fromthe Berlin Aging Study II (N = 1,437), using insulin resistance as an index of glucoregulatorycapacity. We found that poor glucose regulation (higher insulin ...

Can Happiness Apps Generate Nationally Representative Datasets? - a Case Study Collecting Data on People’s Happiness Using the German Socio-Economic Panel

In the last few years, apps have become an important tool to collect data. Especially in the case of data on people’s happiness, two projects have received substantial attention from both the media and the scientific world: “Track your happiness” from Killingsworth and Gilbert (Science, 330, 932-932, 2010), and “Mappiness,” from MacKerron (2012). Both happiness apps used the experience sampling method ...

Comparing Administrative and Survey Data: Is Information on Education from Administrative Records of the German Institute for Employment Research Consistent with Survey Self-Reports?

In research on stratification and inequality, administrative data are popular for their wide coverage and assumed high quality. Yet, the quality of the data depends crucially on the aim of data collection. In this paper, we investigate the quality of information on education in administrative data from social security records provided by the German Federal Institute for Employment Research where education ...

Argumente für Rückkehr zur Meisterpflicht sind wenig überzeugend

Das Bundeskabinett hat die Wiedereinführung der Meisterpflicht für insgesamt zwölf Handwerke beschlossen. Dazu eine Einschätzung von Karl Brenke, Arbeitsmarktexperte des Deutschen Instituts für Wirtschaftsforschung (DIW Berlin):

Yemen's Solar Revolution: Developments, Challenges, Opportunities; Report with Policy Recommendations Based on Results from Research Projects Financed by the Federal Ministry of Education and Research ("FoReSee", 01LA1811B) and the Energy Access and Development Program ("The Future of Yemen's Energy Sector“)

Yemen has been involved in a civil war with foreign military intervention since 2014. Throughout the conflict, the majority of the population have been cut off from the public electricity grid. However, as alternatives have been unavailable, the country has turned to decentralised solar energy, giving rise to an unprecedented deployment of solar (home) systems. This report uses own calculations, new ...

Parental Leave Policies and Socio-Economic Gaps in Child Development: Evidence from a Substantial Benefit Reform Using Administrative Data

This paper examines the effects of substantial changes in paid parental leave on child development and socio-economic development gaps. We analyse a German reform that replaced a means-tested with an earnings-related benefit scheme. Higher-income households benefited relatively more from the reform than low-income households. The reform expanded paid leave in the first year, while it removed paid leave ...

Closing Routes to Retirement for Women: How Do They Respond?

We study the employment effects of a large increase in the early retirement age (ERA) of women. Raising the ERA has the potential to extend contribution periods and to reduce the number of pensioners at the same time. However, workers may not be able to work longer or may choose other social support programs as exit routes from employment. Results suggest that the reform increases employment, unemployment ...

The Fayherriot Command for Estimating Small-Area Indicators

We introduce a command, fayherriot, that implements the Fay–Herriot model (Fay and Herriot, 1979, Journal of the American Statistical Association 74: 269–277), which is a small-area estimation technique (Rao and Molina, 2015, Small Area Estimation), in Stata. The Fay–Herriot model improves the precision of area-level direct estimates using area-level covariates. It belongs to the class of linear mixed ...

European banking landscape between diversity, competition and concentration

The new issue of the Vierteljahrshefte zur Wirtschaftsforschung 4/2018 (Quarterly Journal of Economic Research) on European banking landscape between diversity, competition and concentration is now available. Causes and consequences of institutional diversity are a largely neglected issue in economics. Only in finance, institutional variety has been at times acknowledged, though not in its ‘institution-free’ ...
