We investigate how worries in Germany change across time and age, drawing on both closed-ended questions (which typically list a number of worry items) and open-ended questions answered in text format. We find that relevant world events influence worries. For example, worries about peace peaked in 2003, the year of the Iraq War, with a considerable number of respondents also referring to the Iraq war ...

This paper addresses the behavioral puzzle of women’s preference for competition when competitors are also women. Using a framed field experiment with 883 non-standard subjects, we show that none of the determinants of competitive behavior in general, including ability, self-confidence and risk aversion, provide a satisfying explanation for women’s substantive gender-related selection into competition. ...

Changing employment conditions lead to new chances, but also new risks for employees. In the literature, increasing permeability between occupational and private life is discussed as one special outcome of this development that employees must face, especially those in highly qualified positions. Drawing on existing research, we investigate in how far women and men in those positions differ in their ...

Social norms and attitudes towards gender roles have been shown to have a large effect on economic outcomes of men and women. Many countries have introduced policies that aim at changing gender stereotypes, for example fathers’ quota in parental leave schemes. In this paper, we analyze whether the introduction of the fathers’ quota in Germany in 2007, that caused a sharp increase in the take-up of ...

There is evidence that estimates of long-run impulse responses of structural vector autoregressive (VAR) models based on long-run identifying restrictions may not be very accurate. This finding suggests that using short-run identifying restrictions may be preferable. We compare structural VAR impulse response estimates based on long-run and short-run identifying restrictions and find that long-run ...

Replication studies are considered a hallmark of good scientific practice. Yet they are treated among researchers as an ideal to be professed but not practiced. To provide incentives and favorable boundary conditions for replication practice, the main stakeholders need to be aware of what drives replication. Here we investigate how often replication studies are published in empirical economics and ...

Identification through heteroskedasticity in heteroskedastic simultaneous equations models (HSEMs) is considered. The possibility that heteroskedasticity identifies the structural parameters only partially is explicitly allowed for. The asymptoticproperties of the identified parameters are derived. Moreover, tests for identification through heteroskedasticity are developed and their asymptotic distributions ...

Die Debatte um Arbeitszeiten und deren Regulierung wird in der deutschen Öffentlichkeiterneut geführt. Empirische Grundlage sind dabei häufig Studien auf Basis des Mikrozensusoder des Sozio-oekonomischen Panels (SOEP), die teilweise erhebliche Unterschiede in ihrenErgebnissen aufweisen (Rengers 2015, Holst/Wieber 2014). In dem vorliegenden Beitragwird den Ursachen für diese Unterschiede nachgegangen. ...

We use a lab-in-the-field experiment to investigate intra-couple labor supply decisions and the division of housework under individual and joint income taxation systems. In order to eliminate problems of endogenous intra-couple time use decisions, we exogenously varied not only the taxation system but also the intra-couple roles of primary and secondary earners. Using work effort as a proxy for labor ...

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 ...
