How Important Is the Capacity of Local Governments for Improvements in Welfare? Evidence from Decentralised Uganda

Decentralisation is often claimed to be effective for improvements in welfare and hence the reduction of poverty but empirical evidence is scarce. This paper seeks to gain further insights into the relationship between decentralisation and welfare by investigating the role of local governments' capacity for household consumption and school enrolment in Uganda. Using household survey data, it finds ...

Die Auswirkungen der Geldmenge und des Kreditvolumens auf die Immobilienpreise: ein ARDL-Ansatz für Deutschland

Die aktuellen Finanzmarktturbulenzen wurden durch Entwicklungen im Immobiliensektor ausgelöst. Vor diesem Hintergrund analysiert dieser Beitrag den Zusammenhang zwischen den Immobilienpreisen und der Geldmengen- und Kreditvolumensentwicklung für den Zeitraum 1992 -2006 (westdeutsche Preisdaten) bzw. 1997 bis 2006 (ostdeutsche Preisdaten). Die Untersuchung konzentriert sich erstmals auf die Bundesrepublik ...

A Survey of the Global Economic Costs of Conflict

This paper defines the global economic costs of conflict and suggests two key criteria, namely comprehensiveness and consistency, which are necessary for a valid calculation of such costs. A critical review of the literature reveals that most studies focus on national income losses, using counterfactual regression models, finding a negative impact on growth both for conflict countries themselves and ...

Financial Constraints and Continental Business Groups: Evidence from German Konzerns

Using a unique large panel of German firms, we examine whether participation in business groups (Konzerns) reduces the sensitivity of investment to cash flow. The main finding is that the investment sensitivity is significantly reduced for small firms. On the other hand, we do not find clear evidence that medium-sized and large firms participating in Konzerns have different sensitivity compared to ...

Smart Capital in German Start-ups: An Empirical Analysis

What kind of smart capital relational investors actually supply, especially in a bank-based financial system such as the German one, is still an open question. We divide smart capital into single components and conduct a survey with 85 German suppliers of start-up finance. The results show that the degree of 'smartness' is determined by the financial product used and partly also by the financiers' ...

Locational Conditions, Cooperation, and Innovativeness: Evidence from Research and Company Spin-offs

This paper has two goals. First, it analyzes the extent to which the innovativeness of spin-offs, originating either in a research facility or from another company, is influenced by locational conditions. Second, it provides evidence on how important local cooperation links are in comparison to nonlocal ones. Using a sample of approximately 1,500 East German firms from knowledge-intensive sectors, ...

Empowering Young Scientists

The Vancouver Olympics reveal stark differences between the worlds of sports and science. In both, young people from around the world try to surpass all previous accomplishments in pursuit of world records or scientific discoveries. Selected entirely on merit, athletes receive honor just for participating in the games, spurring the next generation of young people in each nation to excel. And as star ...

A Nonparametric Efficiency Analysis of German Public Transport Companies

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of global and individual constant returns to scale. We find that the average technical efficiency of German bus ...

Investigating M3 Money Demand in the Euro Area

Euro area monetary growth has exceeded its target since 2001. Likewise, recent empirical studies did not find evidence in favour of a stable long-run money demand function. In contrast to the bulk of the literature, we are able to identify a stable long-run money demand relationship. This result is obtained when the analysis is done without the short run homogeneity restriction between money and prices. ...

A Selection Model for Panel Data: The Prospects of Green Party Support

Although sample selection bias is a frequent problem of applied research, there has been no generalization of sample selection models with binary dependent variables of interest to data with temporal error correlations. We suggest a generalized estimating equation approach to panel data selection models, considering binary responses in both equations. We demonstrate the utility of this model by a simulation ...

Does Distance Determine Who Attends a University in Germany

We analyze the role of distance to the nearest university in the demand for higher education in Germany. Distance could matter due to transaction costs or due to neighbourhood effects. We use data from the German Socio-Economic Panel (SOEP) combined with a database on university postal codes to estimate a discrete choice model of the demand for higher education. We show that - controlling for other ...

On the Investment Sensitivity of Debt under Uncertainty

We investigate the impact of debt on a panel of U.S. manufacturing firms' capital investment behavior as the underlying firm-specific and market-level uncertainty changes. Our estimates show that the influence of leverage on capital investment may be stimulating or mitigating depending on the effects of uncertainty.

Armut von Erwerbstätigen im europäischen Vergleich: Erwerbseinkommen und Umverteilung

In Europe, there are significant differences in the extent and in the structure of in-work poverty. Based on a comparison of 20 countries the present study analyses to what extent this is due to the differences in the institutional framework conditions of a given country. The analyses are based on micro data from the EU Statistics on Income and Living Conditions (EU-SILC) of 2006 and macro data from ...

Measurement of Health, Health Inequality, and Reporting Heterogeneity

Using representative survey data of the German Socio-Economic Panel Study (SOEP) for 2006, we show that the magnitude of health inequality measures like the concentration index (CI) depends crucially on the underlying health measure. The highest degree of inequality is found when dichotomized subjective health measures like health satisfaction or self-assessed health (SAH) are employed. With the use ...

A Multi-state Model of State Dependence in Labor Supply: Intertemporal Labor Supply Effects of a Shift from Joint to Individual Taxation

In this paper I develop an intertemporal discrete choice model of female labor supply to analyze the effects of true state dependence and its effect on labor supply behavior over time. The estimation results show that state dependence is significantly positive at the extensive margin and lower but in general still significant at the intensive margin. I apply this model to study the short and long run ...

A Comparison of Electricity Market Designs in Networks

In Europe, two market designs are discussed for electricity trade and transmission. We argue that their performance in the presence of market power can be represented by two models from the literature. In contrast to examples for simple two-node networks, we show that in more complex networks a general ranking of both designs is not possible. Hence, computational models are required to evaluate the ...

Commitments through Financial Options: An Alternative for Delivering Climate Change Obligations

Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO2 allowances. This mechanism gives investors the ...

Seeking Pleasure and Seeking Pain: Differences in Prohedonic and Contra-Hedonic Motivation from Adolescence to Old Age

Using a mobile-phone-based experience-sampling technology in a sample of 378 individuals ranging from 14 to 86 years of age, we investigated age differences in how people want to influence their feelings in their daily lives. Contra-hedonic motivations of wanting either to maintain or enhance negative affect or to dampen positive affect were most prevalent in adolescence, whereas prohedonic motivations ...

Regional Convergence in the Enlarged European Union

There are only a few studies which examine regional convergence in the enlarged European Union. None of these approaches uses a conditional convergence model, which considers different initial conditions of regions. We refer to the Mankiw et al. (1992) model to examine convergence including the New Member States. Note that most researchers use equal values of depreciation rate and rate of technological ...
