Selectivity, Social Ties and Spatial Mobility – An Analysis of Preferences for Return Migration
Lutz Schneider, Alexander Kubis, D. Wiest
Abstract
In the public debate, the brain drain from East Germany is supposed to be the most critical trend regarding the development and catching-up of the New Länder. Therefore, potential for in- and re-migration has attracted much attention at least in the political context. Our contribution analyses the re-migration potential on the basis of data from a DFG research project focussing on the re-migration intentions of people formerly emigrated from Saxony-Anhalt. The analysis concentrates on the following aspects: the effect of job market success after emigration; the impact of social ties to the origin and the host region and on the selectivity of
re-migration preferences. The econometric results confirm several expected effects: On the one hand an individual’s job market success reduces the intention to return. Likewise, the re-migration preference increases for people whose expectations were disappointed. On the other hand, the relevance of social ties to the origin region for re-migration dispositions is confirmed by the estimations. Yet, regarding selectivity of re-migration preferences in terms of human capital econometric results are somewhat ambiguous.

Urban Growth in Germany – The Impact of Localization and Urbanization Economies
Christoph Hornych, Michael Schwartz, Annette Illy, Martin T. W. Rosenfeld
IWH Discussion Papers,
No. 19,
2009
Abstract
This study examines the impact of localization and urbanization economies as well as the impact of city size on urban growth in German cities from 2003 to 2007. Although, from a theoretical perspective, agglomeration economies are supposed to have positive impacts on regional growth, prior empirical studies do not show consistent results. Especially little is known about agglomeration economies in Germany, where interregional support policy and the characteristics of the federal system are further determinants of urban growth. The results of the econometric analysis show a U-shaped relationship between specialization and urban growth, which particularly holds for manufacturing industries. We do not find evidence for the impact of Jacobs-externalities; however, city size shows a positive (but decreasing) effect on urban growth.

A Panel Data Analysis on China's Intra-Industry Trade in the Capital Goods Sector

IWH Discussion Papers,
No. 18,
2009
Abstract
This paper adopts the Hausman-Taylor 2SLS error components approach in estimating the determinants of China's Intra-Industry Trade (IIT) in the capital goods sector with its 26 partner countries. It disaggregates IIT into horizontal IIT (HIIT) and vertical IIT (VIIT). Capital goods final products and intermediates are separately estimated in order to reveal the differentiated trade patterns. It finds that economic similarity is very significantly negatively correlated with the intermediates IIT, but to a less extent correlated with the final products IIT. Factor endowment is of no significance in determining IIT in the intermediates, although it is significantly positively correlated with the final products IIT. Economic size is significantly negatively correlated with both final products and intermediates IIT. Distance is not yet dead in impacting the level of final products IIT, but of less importance in influencing the intermediates IIT. China is exchanging intermediates in a less intraindustry manner with ASEAN nations. However, because VIIT is dominating TIIT, no significant differences exist between the estimation results of TIIT and VIIT.

Cartel Identification in Spatial Markets: An Analysis of the East German Cement Market
Ulrich Blum
Jahrbuch für Regionalwissenschaft,
2009
Abstract
In 2003, the German cement industry was fined more than six hundred million Euros for, allegedly, having fixed prices and quantities in the four regional German cement markets. When this case was finally resolved by the courts in 2009, the fine was reduced by a large amount as the German Antitrust Commission (GAC) was unable to provide sufficient evidence on the level excessive pricing by the cartelists.
This paper takes up again the case of the East German cement cartel that ended in early 2002 and shows that the quota agreement which was established in the mid 1990s was economically inactive. From the perspective of the individual players, the rationale of preserving the cartel can only be explained by limited knowledge of the true market forces. Based on a spatial approach for the years 1997 to 2002, the regional price-setting behavior and its changes can be analyzed against the situation. Econometric analysis suggests that competition was already rather strong in the cartel years as transport costs and rebate systems were used to fine-tune offers. Strategic imports from post-communist countries into the East German market as well as supply from medium-sized enterprises not included in the cartel exerted pressure on the markets.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
IWH Discussion Papers,
No. 16,
2009
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts
based on a number of forecasting techniques from the literature using a panel of
ten industrialized countries during the period of 1988 to 2007. To capture expected
inflation we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Returning to East Germany: Labour Market Success Reduces Re-migration Potential

2009
Abstract
In the public debate, the brain drain from East Germany is supposed to be the most critical trend regarding the development and catching-up of the New Länder. Therefore, potential for in- and re-migration has attracted much attention at least in the political context. Our contribution analyses the re-migration potential on the basis of data from a DFG research project focusing on the re-migration intentions of people formerly emigrated from Saxony-Anhalt. The analysis concentrates on two aspects: firstly on the effect of job market success after emigration; secondly on the impact of social ties in the origin and the host region on the re-migration potential. The econometric results confirm the expected effects: On the one hand, an individual’s job market success in the target region reduces the re-migration potential. Likewise, the re-migration potential increases for people whose former expectations were disappointed. On the other hand, the analysis shows the relevance of social ties to the region of origin for re-migration potential.

Demographic Change and Labour Markets: Why are Older Employees less Mobile?
Lutz Schneider
Wirtschaft im Wandel,
No. 10,
2008
Abstract
Since older workers are less disposed to change jobs workforce ageing will affect labour mobility in Germany. On the basis of the IAB-Employment Sample (IABS) the contribution analyzes the effect of age on job and occupational mobility. The study focuses on the question whether older workers are less mobile due to the optimal matching quality of their current job which cannot be improved by job switches or whether other factors have to be considered for explaining the age related mobility decline.
Econometric results firstly confirm the significance of expected wage growth for mobility decision across all age groups. Secondly, older workers seem to benefit from wage increase due to a job change less frequently than younger workers. However, this factor explains only a part of the mobility lag. Even after controlling for the wage effect younger workers change jobs more often than older ones.
For this reason the opinion that ageing will impede the labour market adjustments cannot be disabled. If older workers only slightly react on wage signals and do not respond to attractive offers growing firms might face problems to recruit appropriate staff – a trend which could have negative consequences for technological and sectoral changes of the entire economy.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Johannes Stephan, Wolfgang Steffen
Eastern European Economics,
No. 6,
2008
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive market-based economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

A Simple Representation of the Bera-Jarque-Lee Test for Probit Models
Joachim Wilde
IWH Discussion Papers,
No. 13,
2007
Abstract
The inference in probit models relies on the assumption of normality. However, tests of this assumption are not implemented in standard econometric software. Therefore, the paper presents a simple representation of the Bera-Jarque-Lee test, that does not require any matrix algebra. Furthermore, the representation is used to compare the Bera-Jarque- Lee test with the RESET-type test proposed by Papke and Wooldridge (1996).
