Why are East Germans not More Mobile? Analyzing the Impact of Social Ties on Regional Migration
Peter Bönisch, Lutz Schneider
Abstract
Individuals’ preferences in transition regions are still shaped by the former communist system. We test this ‘Communism legacy’ hypothesis by examining the impact of acculturation in a communist regime on social network participation and, as a consequence, on preferences for spatial mobility. We focus on the paradigmatic case of East Germany where mobility intentions seem to be substantially weaker than in the western part. Applying an IV ordered probit approach we firstly find that East German people acculturated in a Communist system are more invested in locally bounded informal social capital than West Germans. Secondly, we confirm that membership in such locally bounded social networks reduces the intention to move away. Thirdly, after controlling for the social network effect the mobility gap between East and West substantially reduces. Low spatial mobility of the eastern population, we conclude, is to an important part attributable to a social capital endowment characteristic to post-communist economies.

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-model of Interregional Migration Flows in Germany
Lutz Schneider, Alexander Kubis
Schmollers Jahrbuch,
2010
Abstract
The article analyses the question of whether women and men differ in their tastes for location factors. The question is answered by quantifying the impact of location characteristics on interregional migration flows across Germany. The analysis is based on a grouped conditional logit approach. We augment the framework by controlling for violation of the independence of irrelevant alternatives assumption and for overdispersion. As a result we find no differences in terms of direction of impact; however, the regressions confirm gender differences, mostly in terms of intensity, regarding regional wage levels and the availability of educational institutions. Moreover, even after controlling for place attributes women seem to be more migratory than men.

International Climate Policy after Kyoto – Economic Challenges Ahead
Wilfried Ehrenfeld
Wirtschaft im Wandel,
No. 12,
2009
Abstract
The signs are increasing that the gain in greenhouse gas emissions since the beginning of the 20th century causes the average global temperature to rise. Limiting the temperature rise to 2°C should at least avoid the worst consequences of global warming. This would require the greenhouse gas emissions to reach their maximum value by no later than 2015 and to be dramatically reduced worldwide from that time until 2050. From the economic perspective, there are a number of important questions: In the first place, how can the initial situation be described in economic categories? Therefore, the emissions should first of all be identified by region and sector and thereupon, the adjustment possibilities are to be outlined. Which costs and which revenues are associated with climate policy? The bandwidth of the estimated damage is between 5% and 20% of global gross domestic product (GDP) annually in the case of unmitigated climate change. These estimates are compared to around 1% of global GDP, which would be spent to stabilize the concentration of greenhouse gases in the atmosphere. How are the global targets to be distributed regionally and sectorally, and which economic instruments are recommended for this purpose? Obviously, tradable permits are preferred. Here, the initial assignment and the nature of the allocation on the one hand and the tradability on the other play a prominent role. What politico-economic conflicts arise and what recommendations can economists give to solve these conflicts goal-oriented? Finally, what is to recommend in terms of political economy in order to remain credible in particular in the sense of an international climate agreement?

Russia: A Victim to Transition or to the Financial Crisis?

Wirtschaft im Wandel,
No. 8,
2009
Abstract
The global financial crisis has revealed deficiencies of the Russian economic system which are caused by the path of the transformation from central planning to the market economy, and not only attributable to the downfall of crude oil prices. While the worldwide liquidity crunch impaired the availability of loans to enterprises, the situation in Russia has deteriorated especially by the large exposure of the private sector to short-term foreign liabilities and by the one-sided orientation of the economy relying on the natural resources industry. Until the mid-2008, the foreign debt of the private banks and non-banks had increased strongly and had strengthened the dependence of the Russian economy on the developments on the international financial markets. The Ruble devaluation at the end of January 2009 aggravated the situation. The high short-term foreign debt of the private sector and the dependence on exports of natural resources are typical outcomes of the Russian transformation path. Therefore, on the one hand, the banking sector has not being able to satisfy financing demand of the private sector beyond the natural resources industries, enterprises became forced to borrow short-term money abroad. On the other hand, the economic strategy of the past seventeen years has strengthened the influence of the state on the natural resources sector – with the strong priority to develop it further. Hence, the one-sided economic development negatively affects the adaptability of the real-economic sector to change during the crisis period. In essence, the present political preferences of the government are aimed at providing direct financial assistance and at protectionist measures. In the long run, these actions could lead to stronger intervention of the state in the economy. Due to these recent developments, the crisis is likely to continue in Russia longer than in the other transformation countries.

Possible Ways for Developing a Media City: Chances for Newcomer Cities are rather Limited!
Christoph Hornych, Martin T. W. Rosenfeld, Michael Schwartz
Wirtschaft im Wandel,
No. 5,
2009
Abstract
Numerous cities try to set up themselves as centres of creative businesses, especially for media industry. Behind such strategies for supporting the local media economy stands the aim to profit from the high share of supra-regional sales in the media economy, from possible image effects as well as – especially in Germany – from the backflow of taxes for public broadcasting. Against this background, the article examines the efficiency of possible instruments for local decision makers to improve the location conditions for the media industry. An analysis of the location preferences of the media industry shows that localization economies as well as urbanization economies have a high importance. Economic measures to generate or strengthen these effects are the attraction of public broadcasting stations, the assignment of subsidies for local film and media producers, the endowment with science facilities and educational institutions which are relevant for media, the establishment of business incubators specialized on media industry, and the development of inter-firm networks and special city districts for the local media industry. Our analysis shows that most of these instruments have only limited impacts. In particular, cities without public broadcasting stations and without educational institutions relevant for the branch probably will not have the chance to become media cities.

Effects of Heterogeneity on Bank Efficiency Scores
J. W. B. Bos, Michael Koetter, James W. Kolari, Clemens J. M. Kool
European Journal of Operational Research,
No. 1,
2009
Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Changing patterns of employment
Cornelia Lang
Wirtschaft im Wandel,
No. 4,
2009
Abstract
In Germany, the typical pattern of employment is still an employee with open-ended full time contract (standard employment relationship). Nearly three out of four employed persons work in that type of employment. However, during the last years, a number of other employment models expanded in the labour market: part-time, temporary, short-term and marginal workers. Main reasons for that development are the effects of globalization, the structural change in modern economies (the increasing importance of the services sector), and changing preferences on the part of employees to achieve a better work-life-balance. The article deals with the rise of atypical employment relationships. We find that atypical work is a domain of female and young people. During the last years, atypical employment relationship in West and East Germany increased similarly due to globalization. Differences in employment patterns between East and West could be linked to employment behaviour and structural determinants.

A Novel Approach to Incubator Evaluations: The PROMETHEE Outranking Procedures
Michael Schwartz, Maximilian Göthner
IWH Discussion Papers,
No. 1,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that has focused on the outcomes or effectiveness of incubator initiatives and how to measure incubator performance, there is still little understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, this paper applies the multi-criteria outranking technique PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and compares the long-term effectiveness of five technology-oriented BIs in Germany. This is the first time that outranking procedures are used in incubator evaluations. In particular, we investigate whether PROMETHEE is a well-suited methodological approach for the evaluation and comparisons in the specific context of business incubation.
