The overhaul of the German system of old-age provision raises concerns about the future distribution of pension rights. Therefore, it is critical to gain a thorough understanding of the role pension wealth plays in the individual's total wealth holdings, but also what individual-level and institutional factors facilitate or impede successful pension building that allow individuals to retire with a ...

This paper analyses monthly hours worked in the US over the sample period 1939m1 - 2011m10 using a cyclical long memory model; this is based on Gegenbauer processes and characterised by autocorrelations decaying to zero cyclically and at a hyperbolic rate along with a spectral density that is unbounded at a non-zero frequency. The reason for choosing this specification is that the periodogram of the ...

We empirically demonstrate a practical approach of efficiency evaluation with limited data availability in some regulated industries. We apply PCA-DEA for radial efficiency measurement to U.S. natural gas transmission companies in 2007. PCA-DEA reduces dimensions of the optimization problem while maintaining most of the variation in the original data. Our results suggest that the methodology reduces ...

The amendment to the German Trade and Crafts Code in 2004 offers a natural experiment to asses the causal effects of this reform on the probabilities of being self-employed and transition into and out of self-employment, using cross-sections (2002-2006) of German microcensus data. This study applies the difference-in-differences technique in logit models for four occupational groups. Easing the educational ...

Population surveys around the world face the problem of declining cooperation and participation rates of respondents. Not only can item nonresponse and unit nonresponse impair important outcome measures for inequality research such as total household disposable income; there is also a further case of missingness confronting household panel surveys that potentially biases results. The approach commonly ...

Im Rahmen des europäischen Binnenmarktes stellt sich die Frage, wie sich die deutsche Industrie im Vergleich zu der anderer großer EU-Länder entwickelt. Welche Indikatoren sind zur Messung der relativen Position der Industrie und ihrer Zweige unter konjunkturellen und strukturellen Aspekten im europäischen Rahmen geeignet? In diesem Bericht werden Indikatoren wie der Produktionsindex und die reale ...

This paper shows that there are severe measurement errors regarding the occupational affiliations in the German Socio-Economic Panel. These errors are traced back to the survey structure: in years where occupational information is gathered from the entire employed population instead of only from those declaring job or labor market status changes, average occupational mobility is around five times higher. ...

We show that the choice of the welfare measure has a substantial impact on the degree of welfare-related health inequality. Combining various income and wealth measures with different health measures, we calculate 80 health concentration indices. The influence of the welfare measure is more pronounced when using subjective health measures than when using objective health measures.

In recent decades, many firms offered more discretion to their employees, often increasing the productivity of effort but also leaving more opportunities for shirking. These "high-performance work systems" are difficult to understand in terms of standard moral hazard models. We show experimentally that complementarities between high effort discretion, rent-sharing, screening opportunities, and competition ...
