Abstract
The current contribution presents poverty indicators for West and East Germany for the years 1995 and 2009. The analysis is based on the two corresponding waves of the GSOEP. We only consider households with at least one senior citizen aged 65 or above. Furthermore, we distinguish between male and female pensioners. In the first part the weighted equivalized household income is calculated as well as various statistical measures such as the 20%- and 80%-percentile, the 80/20-ratio and the 90/10-ratio of the income distribution of senior citizen households. In an additional step we also present and discuss the main sources of income such households have. In the second part of the contribution we focus on social indicators with respect to the satisfaction with income and the current living conditions as well as the expected situation in five years. As the results show, old age poverty has increased in both parts in Germany with East German women being an exception. With respect to the future, most elder people look optimistically into the future.

The Revealed Competitiveness of U.S. Exports

Federal Reserve Discussion Paper,
No. 1026,
2011
Abstract
The U.S. share of world merchandise exports has declined sharply over the last decade. Using data at the level of detailed industries, this paper analyzes the decline in U.S. share against the backdrop of alternative measures of the competitiveness of the U.S. economy. We document the following facts: (i) only a few industries contributed to the decline in any meaningful way, (ii) a large part of the drop was driven by the changing size of U.S. export industries and not the size of U.S. sales within those industries, (iii) in a gravity framework, the majority of the decline in the U.S. export share within industries was due to the declining U.S. share of world income, and (iv) in a computed structural measure of firm productivity, average U.S. export productivity has generally maintained its high level versus other countries over time. Overall, our analysis suggests that the dismal performance of the U.S. market share is not a sufficient statistic for competitiveness.

Betriebsräte und betriebliche Produktivität

Abstract
Employee participation via works councils is at the heart of the industrial relations in Germany. Despite considerable research, there is still no consensus on the effect works councils exert on establishment productivity. I estimate the statistical relationship between works council existence and establishment productivity using the most recent information from the IAB establishment panel and find that works council existence is related with a nine percent higher productivity. Based on the results of earlier studies, it is argued that the productivity effect of works councils exceeds the estimated statistical relationship.

Analyse der Patentaktivitäten in den öffentlichen Wissenschaftseinrichtungen des Freistaates Sachsen im Auftrag des Sächsischen Staatsministeriums für Wissenschaft und Kunst (SMWK)

Abstract
This study analyses patenting activities by public research organizations (PROs) in the Free State of Saxony in the period 2002-2007 in order to shed some light on the strategies of PROs for industrial exploitation of scientific research results as well as on PROs-industry interaction. The analysis is based on published patent applications at the German Patent and Trademark Office (DPMA) in the period 2002-2007. The study shows that in the period of analysis (2002-2007) the number of patent applications by PROs in Saxony has risen almost continuously. Institutes of the Fraunhofer-Gesellschaft and the Technical University of Dresden have played a major role in this development. The results for PROs in Saxony are compared with patenting by PROs located in the states of Thuringia, Lower Saxony and North Rhine-Westphalia. Overall, the comparative analysis shows positive results for the industrial exploitation of scientific research results by PROs in Saxony. In what concerns the networking of PROs with private companies through co-patenting, there are no significant differences between the PROs of the four states considered. The results suggest that PROs in Saxony could further improve their performance in PROs-industry interaction. These results should however be interpreted with caution since the underlying patent statistics (co-patenting) do not capture all forms of PROs-industry interaction for the industrial exploitation of research results.

Distance Functions for Matching in Small Samples

Computational Statistics & Data Analysis,
No. 5,
2011
Abstract
The development of ‘standards’ for the application of matching algorithms in empirical evaluation studies is still an outstanding goal. The first step of the matching procedure is the choice of an appropriate distance function. In empirical evaluation situations often the sample sizes are small. Moreover, they consist of variables with different scale levels which have to be considered explicitly in the matching process. A simulation is performed which is directed towards these empirical challenges and supplements former studies in this respect. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, two balancing scores (the propensity score and the index score) and the Mahalanobis distance are considered. Additionally, aggregated statistical distance functions not yet used for empirical evaluation are included. The matching outcomes are compared using non-parametric scale-specific tests for identical distributions of the characteristics in the treatment and the control groups. The simulation results show that, in small samples, aggregated statistical distance functions are the better choice for summarising similarities in differently scaled variables compared to the commonly used measures.

The Russian System of Cities from the Perspective of New Economic Geography
Albrecht Kauffmann
Potsdamer Schriften zur Raumwirtschaft, Bd. 2,
2010
Abstract
The rise in energy prices may result in long-lasting rise in costs of freight transports. Which effects do rising freight transport costs have for the development of urban systems? Such rise of transport costs in real terms has happened in Russia after price liberalisation in 1992. At the same time, the Russian official demographic statistics provides data that can be used to test hypotheses concerning the development of urban systems affected by rising transport costs. In the present study, these data are comprehensively evaluated. The theoretical background is provided by modelling of a linear shaped urban system in the framework of New Economic Geography. By means of this tool, analysis can be applied to spacious urban systems with large transport distances. For the first time, the underlying theoretical approach is explained in detail. The empirical results provide evidence for the outcomes of the theoretical model: In spacious countries or regions, respectively, whose urban systems are drawn-out on long lines, rising costs of freight transport are conducive to tendencies of concentration of population in large cities in the centre of the system, while peripheral regions are increasingly disconnected.

Incubation Time, Incubator Age, and Firm Survival after Graduation
Michael Schwartz
International Journal of Entrepreneurship and Innovation Management,
2012
Abstract
On the basis of a sample of 149 graduate firms from five German business incubators, this article contributes to incubator/incubation literature by investigating the effects of the age of the incubators and the firms´ incubation time in securing long-term survival of the firms after leaving the incubator facilities. The empirical findings from Cox proportional hazards regression and parametric accelerated failure time models reveal a statistically significant negative impact for both variables incubator age and incubation time on post-graduation firm survival. One important implication that follows from the empirical results for policy makers and managers of those initiatives is that, when incubator managers become increasingly involved in various regional development activities, this may reduce the effectiveness of incubator support. Also, our finding speaks in favour of a strict limitation of incubation times and reinforces arguments of the supporters of maximum tenancy.

A Control Group Study of Incubators’ Impact to Promote Firm Survival
Michael Schwartz
Wirtschaft im Wandel,
No. 7,
2010
Abstract
For more than half a century, publicly funded business incubators (BIs) are at the heart of urban and regional technology and innovation policies. However, it is widely unclear as to whether start-up firms supported by publicly-initiated incubator initiatives have higher survival rates than comparable start-up firms that have not received support by such initiatives. The present article contributes to the underlying discussion by performing an empirical analysis of the long-term survival of 371 incubator firms (after their graduation) from five German BIs and contrasting these results with the long-term survival of a control group of 371 comparable non-incubated firms. The analysis covers a 10-year time span. For neither of the five incubator locations, we find statistically significant higher survival probabilities for firms located in incubators compared to firms located outside those incubator organizations. For three incubator locations the analysis even reveals statistically significant lower chances of survival for those start-ups receiving support by an incubator. We therefore arrive at the conclusion that being located in an incubator does not increase the chances of long-term business survival.

Journal of Financial Services Research,
No. 2,
2010
Abstract
This paper provides evidence on the relationship between finance and growth in a fast growing country, such as China. Employing data of 27 Chinese provinces over the period 1995–2003, we study whether the financial development of two different types of financial institutions — banks and non-banks — have a (significantly different) impact on local economic growth. Our findings indicate that banking development shows a statistically significant and economically more pronounced impact on local economic growth.
