Central versus Local Education Finance: A Political Economy Approach

This paper models voters' preferences over central versus local education policies when there are private alternatives. Education is financed by income taxes and individuals are mobile between communities. Public education levels are chosen by majority vote. Contrary to conventional wisdom, centralisation may benefit the rich and poor, while the middle class prefer decentralised education. The model ...

Measuring Ethnic Identity and Its Impact on Economic Behavior

This article advocates for a new measure of the ethnic identity of migrants, models its determinants, and explores its explanatory power for economic performance. The ethnosizer, a measure of the intensity of a person's ethnic identity, is constructed from information on the following elements: language, media, ethnic self-identification, ethnic networks, and residency plans. The two-dimensional concept ...

Life Satisfaction Shows Terminal Decline in Old Age: Longitudinal Evidence from the German Socio-Economic Panel Study (SOEP)

Longitudinal data spanning 22 years, obtained from deceased participants of the German Socio-Economic Panel Study (SOEP; N = 1,637; 70- to 100-year-olds), were used to examine if and how life satisfaction exhibits terminal decline at the end of life. Changes in life satisfaction were more strongly associated with distance to death than with distance from birth (chronological age). Multiphase growth ...

Carbon Capture and Storage: Settling the German Coal vs. Climate Change Dispute?

Technological Change and Transition: Relative Contributions to Worldwide Growth during the 1990s

In this paper we use the Kumar and Russell [American Economic Review (2002) Vol. 92, pp. 527-548] growth-accounting procedure to examine cross-country growth during the 1990s. Using a data set comprising developed, newly industrialized, developing and transitional economies, we decompose the growth of output per worker into components attributable to technological catch-up, technological change and ...

Overtime Work as a Signaling Device

This paper provides an explanation for the empirically proven relationship between overtime and future benefits. We suggest an internal signaling model, in which a worker signals his value to the employer by supplying unpaid overtime. In our empirical analysis, we examine whether overtime has in fact a signaling component. Variations in collectively bargained hours between industries are exploited, ...

Leistungs- oder Bedarfsgerechtigkeit? Über einen normativen Zielkonflikt des Wohlfahrtsstaats und seiner Bedeutung für die Bewertung des eigenen Erwerbseinkommens

Der Beitrag analysiert den Zielkonflikt zwischen Leistungs- und Bedarfsgerechtigkeit in modernen Wohlfahrtsstaaten und das fundamentale Problem, weshalb die Abgabenund Steuerlast von den Bürgern akzeptiert wird. Es wird die Frage beantwortet, inwieweit ein auf der Makroebene der Gesellschaft bestehendes Steuerungsproblem moderner Wohlfahrtsstaaten auch in der individuellen Wahrnehmung Gerechtigkeitsprobleme ...

Using survey data from the German Socioeconomic Panel, it examines the link between city size and different measures of consumption, social interaction and social capital. There is strong evidence of agglomeration effects in consumption, while positive effects of city size on social interaction and social capital variables seem to some extent ...

Data for the empirical investigation originates from a sample of 7302 European enterprises. The empirical results show that Internet-based technologies were an important enabler of innovation in the year 2003. It was found that all studied types ...

Publications: German Economic Research Institutes on Track

About a decade ago the German Science Council requested a strengthening of academic research at the German economic research institutes to improve the academic foundation of policy advice - the traditional task of the institutes. Based on publications in SSCI journals, research output has since then improved remarkably in scope and quality and has involved an ever rising number of scholars within the ...

O Brother, Where Art Thou? The Effects of Having a Sibling on Geographic Mobility and Labour Market Outcomes

This paper formulates a model to explain how parental care responsibilities and family structure interact in affecting children's mobility characteristics. Our main result is that the mobility of young adults crucially depends on the presence of a sibling. Siblings compete in location and employment decisions to direct parental care decisions towards their preferred outcome. Only children are not exposed ...

Subjective Income and Employment Expectations and Preferences for Redistribution

Using probabilistic expectations data from the German Socio-Economic Panel, we establish a link between self-reported expectations of occupational mobility and preferences for redistribution. Our results provide new evidence on the validity of the "prospect of upward mobility" hypothesis. (

Isometrische Greifkraft und sozialgerontologische Forschung: Ergebnisse und Analysepotentiale des SHARE und SOEP

Dieser Aufsatz zeigt, dass die Messung der Handgreifkraft ein auch in sozialwissenschaftlichen Bevölkerungsumfragen einfach zu ermittelndes, nicht-invasives und verlässliches objektives Gesundheitsmaß ist. Die Greifkraftmessung stellt nicht nur eine sinnvolle Ergänzung zu selbst berichteten Indikatoren des Gesundheitszustandes dar, sondern besitzt darüber hinaus hinsichtlich einer Vielzahl insbesondere ...

Is Entrepreneurial Success Predictable? An Ex-Ante Analysis of the Character-Based Approach

This paper empirically analyzes whether the character-based approach, which focuses on the personality structure and the human capital of business founders, allows prediction of entrepreneurial success. A unique data set is used consisting of 414 persons whose personal characteristics were analyzed by different methods, namely an one-day assessment center (AC) and a standardized questionnaire, before ...

Downsizing in the German Chemical Manufacturing Industry during the 1990s

The German chemical manufacturing industry experienced major downsizing between 1992 and 2004, with the average size of firms shrinking by nearly half during this period. This study uses modern frontier efficiency analysis to investigate the determinants of this downsizing. Based on reliable census data, the results of this analysis suggest that firms were not primarily concerned with improving technical ...

The Impact of Income Taxation on the Ratio between Reservation and Market Wages and the Incentives for Labour Supply

This article extends previous research about the determinants of reservation wages by analysing the effect of progressive income taxation on the ratio between reservation and net market wages. Based on micro data for Germany Socio-Economic-Panel (SOEP) we show that joint income taxation in Germany which discriminates by marital status, has a strong and highly significant impact on the reservation/market ...

Risk Attitudes of Nascent Entrepreneurs

The influence of risk aversion on the decision to become self-employed is a much discussed topic in the entrepreneurial literature. Conventional wisdom asserts that being an entrepreneur means making risky decisions; hence more risk-averse individuals are less likely to become entrepreneurs. In contrast to previous research, we are able to examine empirically whether the decision of starting a business ...

Income Taxes and Entrepreneurial Choice: Empirical Evidence from Germany

Does tax policy affect entrepreneurial choice? We use two tax reforms in Germany as "natural experiments". These reforms reduced the marginal income tax rate for entrepreneurs with income above a certain threshold, with the exception of freelance professionals. The two conditions for belonging to the treatment group allow us to apply a "difference-in-difference-in-difference" identification strategy ...

Evaluating the German Mini-Job Reform Using a Natural Experiment

Increasing work incentives for people with low income is a common topic in the policy debate across European countries. The 'Mini-Job' reform in Germany had a similar motivation. We carry out an ex-post evaluation to identify the short-run effects of this reform. Our identification strategy uses an exogenous variation in the interview months in the Socio-Economic Panel Study (SOEP), which allows us ...
