Making Work Pay: Increasing Labour Supply of Secondary Earners in Low Income Families with Children

In-work support through the tax-benefit system has proved to be an effective way of increasing thelabor supply of lone mothers and first earners in couples in a number of OECD countries. At the sametime, these instruments usually create negative employment incentives for secondary earners. This inturn reduces the potential of in-work support to address the joint objectives of higher employmentand lower ...

Do Entrepreneurs Really Earn Less?

Based on large representative German household survey data, we compare incomes of the self-employed with those of paid employees. We find that the entrepreneurial income gap is largest for those holding a tertiary degree, but in two directions: positive for employers (self-employed with further employees) and negative for solo entrepreneurs. Entrepreneurs holding a tertiary degree also face the greatest ...

Civil Liberties vs. Security: Why Citizens Accept or Reject Digital Security Measures

Fundamental changes to security policy in European democracies raise the question of the acceptance of new security measures. This paper aims to explain why new measures are accepted (or not). It combines three core elements that are typically analysed separately in the literature: individual attitudes (especially trust), social context and cost/benefit balancing. Comparing Germany and the UK, the ...

The Impact of Extreme Weather Events on Education

This paper provides new evidence on the long- and medium-term impact of extreme weather events on education. Our focus is on Mongolia, where two extremely severe winters caused mass livestock mortality. We use household panel data with information on households' pre-shock location, combined with historic district-level livestock census data and climate data. Our econometric strategy exploits exogenous ...

Immigrant Occupational Composition and the Earnings of Immigrants and Natives in Germany: Sorting or Devaluation?

In this article, the influence of immigrant occupational composition on the earnings of immigrants and natives in Germany is examined. Using data from the German Socio-Economic Panel Study and the German Microcensus, several relevant concepts are tested. The notion of quality sorting states that the differences in wages that are associated with the immigrant share within occupations are due only to ...

Replikationen, Reputation und gute wissenschaftliche Praxis

In Zeiten wachsender Publikationszahlen und zunehmend datenintensiver Forschung stoßen die klassischen Qualitätssicherungsmaßnahmen, wie die Peer-Review, an ihre Grenzen. Vor diesem Hintergrund werden Replikationsstudien verstärkt als gute wissenschaftliche Praxis und Lösungsansatz diskutiert, um dem Problem methodisch unzureichender und oftmals fehlerbehafteter Analysen zu begegnen. Denn schlechte ...

Euro Area Government Bonds: Fragmentation and Contagion during the Sovereign Debt Crisis

The paper analyzes the integration of euro area sovereign bond markets during the European sovereign debt crisis. It tests for contagion (i.e., an intensification in the transmission of shocks across countries), fragmentation (a reduction in spillovers) and flight-to-quality patterns, exploiting the heteroskedasticity of intraday changes in bond yields for identification. The paper finds that euro ...

Structural Vector Autoregressions with Smooth Transition in Variances

In structural vector autoregressive analysis identifying the shocks of interest via heteroskedasticity has become a standard tool. Unfortunately, the approaches currently used for modeling heteroskedasticity all have drawbacks. For instance, assuming known dates for variance changes is often unrealistic while more flexible models based on GARCH or Markov switching residuals are difficult to handle ...

Terminal Decline in Well-Being Differs between Residents in East Germany and West Germany

Lifespan research has long been interested in how contexts shape individual development. Using the separation and later reunification of Germany as a kind of natural experiment we examine whether and how living and dying in the former East or West German context has differentially shaped late-life development of well-being. We apply multi-level growth models to annual reports of life satisfaction collected ...
