Unions decide how to allocate their resources to organise new workers and to benefit existing members. While there is a growing literature studying the aggregate effects of shocks to union power, little is known about how individual unions change their behaviour in response to these shocks. We illustrate the importance of accounting for union equilibrium responses when studying the impact of...
A central assumption for identifying structural shocks in vector autoregressive (VAR) models via heteroskedasticity is the time-invariance of the impact effects of the shocks. It is shown how that assumption can be tested when long-run restrictions based on the cointegration structure of the variables are available for identifying structural shocks. The importance of performing such tests is illustrated ...
Multiple imputation of missing values in survey data analysis is a state-of-the-art technique. Typically, methods like multivariate imputation by chained equations (mice, van Buuren 2018) are employed, replacing missing values on a variable-by-variable basis. Generally, the information used for imputation comes from the survey dataset being analysed. Valid analysis results are achieved when the...
SOEP researcher Cristóbal Moya participated in a large international study on the replicability of social and behavioral science research, which was published in the prestigious journal Nature. As part of the SCORE project, 274 findings from 164 scholarly articles were independently evaluated. Approximately half of the findings could be replicated, although the measured effects were often smaller ...
FAIRness of research data, meaning that data are managed according to the principles of being Findable, Accessible, Interoperable, and Reusable, has become a ubiquitous requirement in research data policies as well as in general guidelines for research data management. Meeting this requirement largely depends on the availability of rich and standardized DDI metadata—based on the Data Documentation ...
Prof. Dr. Franziska Holz, Deputy Head of the Department of Energy, Transport, Environment, and Dr. Wolf-Peter Schill, Head of the Research Department "Transformation of the Energy Industry" in the Department of Energy, Transport, Environment were appointed members of "Energy System of the Future" (ESYS) in December 2025 for the next three years. ESYS is an initiative of the German Academy of Science ...
