This paper analyzes the effects of the 1994 genocide in Rwanda on fertility outcomes. We study the effects ofviolence on both the timing of the first birth after the genocide and the total number of post-genocide births. Weanalyze individual-level data from several Demographic and Health Surveys, using event history and count datamodels. The paper contributes to the literature on the demographic effects ...
We live in a time of increasing publication rates and specialization of scientific disciplines. More and more, the research community is facing the challenge of assuring the quality of research and maintaining trust in the scientific enterprise. Replication studies are necessary to detect erroneous research. Thus, the replicability of research is considered a hallmark of good scientific practice and ...
In the New England Journal of Medicine, Longo and Drazen critically assessed the concept of data sharing. Their main concern is that a "new class of research person will emerge" that uses data, which were gathered by other researchers, for their own original research questions. The authors referred to this class of researcher as "research parasites". Longo and Drazen are right when they note that scientific ...
We analyze the link between R&D, innovation, and productivity in MSMEs with a special focus on micro firms with fewer than 10 employees; usually constituting the majority of firms in industrialized economies. Using the German KfW SME panel, we examine to what extent micro firms are different from other firms in terms of innovativeness. We find that while firms engage in innovative activities with smaller ...

A puzzle of the modern welfare state is that a large fraction of social benefits is not takenup. Using a laboratory experiment, we present evidence that stigmatization through publicexposure causally reduces the take-up of a redistributive transfer by 30 percentage points.We build a theoretical model that interprets welfare stigma as unfavorable inferencesabout the claimant's type. Our design exogenously ...
This paper aims to verify results of the innovative study on gender identity for the USA by Bertrand et al. (2015) for Germany. They found that women who would earn more than their husbands distort their labor market outcome in order not to violate traditional gender identity norms. Using data from the German Socio-economic Panel Study we also find that the distribution of the share of income earned ...
Job search requirements constrain the effort choice of unemployment insurance recipients by enforcing a minimum number of monthly applications. This paper is the first to assess how individual search effort, job finding and job stability react to this constraint. Standard job search theory predicts that requirements affect each job seeker relative to her unconstrained effort choice. Therefore, the ...
