Duration of maternity leave in Germany: A case study of nonparametric hazard models and penalized spines

The paper investigates maternity leave behavior in West Germany for females being employed between 1995 and 2006 using data from the German Socio Economic Panel. The observational study focuses on the investigation of individual and family-related covariate effects on the duration of maternity leave following first or second childbirth, respectively. Dynamic duration time models are used in which covariate ...

Who leaves and when? Selective outmigration of immigrants from Germany

The paper provides new evidence on the outmigration of foreign-born immigrants. We make use of data from the German Socio-Economic Panel and employ penalised spline smoothing in the context of a Poisson-type Generalised Additive Mixed Model (GAMM), which enables us to incorporate bivariate interaction effects. A unique feature is the use of data from dropout studies to identify outmigration. For Turkish ...

Trends in gender differences in health at working ages among West and East Germans

Before 1990, Germany was divided for more than 40 years. While divided, significant mortality disparities between the populations of East and West Germany emerged. In the years following reunification, East German mortality improved considerably, eventually converging with West German levels. In this study, we explore changes in the gender differences in health at ages 20–59 across the eastern and ...

Policy Effects on Behaviour: Persuasion Effects in Electoral Campaigns – A Comparative Analysis of Household Panel Data

This study looks at the campaign effects of national elections, using household panel surveys from Germany, Great Britain and Switzerland. As household panels collect the party preferences of the same individuals on an annual basis, we are able to study individual dynamics over the electoral cycle. This makes it easier to distinguish between activation and persuasion effects than studying electoral ...

From Strangers to Acquaintances? Interviewer Continuity and Socially Desirable Responses in Panel Surveys

In many panel surveys that rely on face-to-face interviewing, interviewers are repeatedly allocated to the same respondents in each wave. Researchers and fieldwork agencies argue that interviewer continuity can contribute to the quality of the data collected, for instance, by reducing panel attrition. However, there is almost no empirical evidence focusing on the effects of growing familiarity between ...

Sampling in Times of High Immigration: The Survey Process of the IAB-BAMF-SOEP Survey of Refugees

Over the course of 2013 to 2016, over one million asylum seekers arrived in Germany, around 890,000 of them in 2015 alone. The growing refugee population posed a major challenge for Germany’s policy makers, civic administrators, and society at large, in finding new approaches to registration procedures, housing, and social and economic integration. To design policies and programs that meet these needs, ...

Personalized Feedback in Web Surveys: Does it Affect Respondents' Motivation and Data Quality?

Web surveys technically allow providing feedback to the respondents based on their previous responses. This personalized feedback may increase respondents’ motivation and possibly the accuracy of responses. While past studies mainly concentrate on the effects of providing study results on future response rates, thus far survey research lacks theoretical and empirical contributions on the effects of ...

Comparing Self-Reported and Partnership-Inferred Sexual Orientation in Household Surveys

Research comparing heterosexuals with bisexuals and homosexuals in economics and the social sciences typically relies on two strategies to identify sexual orientation in existing survey data of general populations. Probing respondents to self-report their sexual orientation is generally considered the preferred option. Since self-reports are unavailable in most large multidisciplinary surveys, often ...
