We study the wage and employment effects of a German place-based policy using a research design that exploits conditionally exogenous EU-wide rules governing the program parameters at the regional level. The place-based program subsidizes investments to create jobs with a subsidy rate that varies across labor market regions. The analysis uses matched data on the universe of establishments and...

The German Socio-Economic Panel Study is a representative panel study for the German population, collecting data on a broad variety of topics of everyday life, including general well-being, household composition, educational aspirations and educational status, income and occupational biographies, leisure time activities, housing, health, political orientation and more. With its long running panel...

A consistent finding in research on the success of right-wing populist parties is that they gain support in regions that are peripheralized. In such regions, the decline of manufacturing jobs, public services, and infrastructure is thought to lead to growing frustration with democratic institutions and mainstream political parties, providing opportunities for right-wing populist parties to...

The replicability crisis highlights the need for more transparent and robust research practices. Lab² (Lab-Square) is a collaborative initiative using meta-scientific approaches to improve research credibility. Through large-scale projects like Many-Labs, Many-Designs, and Many-Analysts, we assess the generalizability of findings across populations, methods, and analytical approaches. Lab² also...

Report
We are happy to announce the launch of the #ManyDaughters Study, an international research initiative exploring how having daughters influences behavior, preferences, and attitudes. Researchers from all fields of social sciences are invited to participate in this collaborative project, which will use data from the German Socio-Economic Panel (SOEP) to test four key hypotheses on the impact of daughters ...

Item nonresponse is a common issue in surveys. We implement an experiment to reduce nonresponse to income questions in an international household survey, looking at four different countries. Survey respondents are asked to report their exact household income. We randomize those who refuse to answer into two groups. In a follow-up question, the control group is asked to choose their income from a...

Fast online surveys without sampling frames are becoming increasingly important in survey research. Their recruitment methods result in non-probability samples. As the mechanism of data generation is always unknown in such samples, the problem of non-ignorability arises making vgeneralisation of calculated statistics to the population of interest highly questionable. Sensitivity analyses provide a ...

This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from an original study of policy preferences and immigration. Reproduction teams were randomly grouped into a ‘transparent group’ receiving original study and code or ‘opaque group’ receiving only a method ...

Data quality is known to be compromised when respondents cognitively shortcut the survey response process. This satisficing behavior leads to inaccurate and unreliable responses that are hard to compensate after data collection. Thus, detecting and understanding survey satisficing is crucial for developing and implementing effective preventive measures in longitudinal data collection contexts. We use ...
