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...

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, ...

Evidence on how proximity to ethnic outgroups shapes attitudes toward immigration remains inconclusive. We suggest this may be driven, in part, by the fact that studies rarely account for the role of residential segregation. We argue that how the minority-share in an environment affects majority-group attitudes will depend on how segregated groups are from one another. To explore this, we undertake ...

Economic and social scientists are increasingly interested in historical data, but many relevant sources are still available in analog form, limiting accessibility and research potential. This article introduces the WBdigital database, which aims to improve this situation. The database provides digital access to the DIW Wochenbericht (1928–1968), including its economic texts and time series data covering ...

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 study explores the effect of frequent green-bond issuance on a firm's financing costs. Using a sample of listed Swedish real estate companies issuing a total of 1074 bonds over the period from 2011 to 2021, difference-in-differences analyses and instrumental variable estimations are applied to identify the causal impact of frequent green-bond vis-à-vis frequent non-green-bond issuance on a firm's ...

In this special Brownbag Session, we will present the platform SOEP Statistics to receive feedback from the SOEP team before we go into a final pre-launch phase. SOEP Statistics is both a data explorer and a tool to export weighted descriptive statistics of pre-screened longitudinal variables on all SOEP topics. The platform allows users to group data according to a pre-defined selection of...

Despite millions of war widows worldwide, little is known about the economic consequences of being widowed by war. We use life history data from West Germany to show that war widowhood increased women’s employment immediately after World War II but led to lower employment rates later in life. War widows, therefore, carried a double burden of employment and childcare while their children were young...

This study sheds light on the impact of different types of job retention programs such as short-time work (STW). We analyze the causal effect of an episode of STW on labor market outcomes up to five years later and compare this to the effects of sudden unemployment episodes. Using data from German Socio-Economic Panel (1992–2022), we employ an event-study approach to analyze the effect of...
