The German Socio-Economic Panel Study (SOEP) is a multidisciplinary household panel study that covers a wide range of social and behavioral sciences, including economics, sociology, psychology, survey methodology, econometrics, educational science, political science, public health, behavioral genetics, demography, geography, and sport science. SOEP is designed as a research infrastructure for socio-economic researchers and has been continuously developed since its inception in 1984. It has undergone several improvements over the years, including expanding its sample to cover more diverse groups, enhancing data collection methods, and introducing new variables to better capture the complexity of social and economic phenomena. SOEP has been instrumental in providing longitudinal data that is essential for analyzing intergenerational transmissions of behavior and social structures, as well as for evaluating public policy programs. The study has also been at the forefront of incorporating new concepts from medicine and psychology into its research, such as health and “other regarding preferences” like trust, fairness, and reciprocity. This has allowed SOEP to become a more open academic research tool and has contributed to the development of new methodologies for analyzing longitudinal data. The SOEP has also been involved in the development of new data collection methods, including the introduction of new modes of data collection for SOEP. It has also been involved in the development of new data sets that are internationally comparable, such as the Cross-National Equivalent File (CNEF), which provides a common database derived from existing national panels. This has allowed SOEP to contribute to the development of new research questions and methodologies in the social sciences.
