Abstract
Regional economic projections are fundamental for political decision-making in several fields, including land use. Residential as well as commercial land use is affected by regional economic growth. This article describes the methodology and problems of regional economic projections using the example of a medium and long-term projection model for the economic development in Germany and the German states. The model utilizes the production function approach and updates the factors of production, labor and capital, as well as productivity via time series econometric methods. The results for Germany as a whole show that gross domestic product will continue increasing during the time period of 2011 to 2025 despite the demographically caused decline of hours worked. However, the varying forms of demographic change in the German states will lead to regional growth differentials. This is exemplified by a comparison between Saxony and Baden-Württemberg.

A Federal Long-run Projection Model for Germany
Oliver Holtemöller, Maike Irrek, Birgit Schultz
IWH Discussion Papers,
No. 11,
2012
Abstract
Many economic decisions implicitly or explicitly rely on a projection of the medium- or long-term economic development of a country or region. In this paper, we provide a federal long-run projection model for Germany and the German states. The model fea-tures a top-down approach and, as major contribution, uses error correction models to estimate the regional economic development dependent on the national projection. For the medium- and long-term projection of economic activity, we apply a production function approach. We provide a detailed robustness analysis by systematically varying assumptions of the model. Additionally, we explore the effects of different demographic trends on economic development.

Sweden’s Policy for Guaranteeing Service Provision Based on the Example of Jämtland
Franziska Jungermann
Europa Regional,
No. -1,
2012
Abstract
The northern Swedish Jämtland county is among the most sparsely populated regions in Europe. Due to its rural/peripheral character and a dispersive settlement structure, it is particularly called upon to maintain adequate service provision. An empirical study analysed the provisions of services of general interest for children and elderly persons and adult education in the Country of Jämtland to discover how the various types of services of general interest are organised in this area, what effect the demographic change has on the provision of these services and whether any adjustment processes can be observed. It became apparent that the local players have a clear awareness of the problems related to the demographic change, although to date one cannot speak of explicit adjustment processes.

Municipality Size and Efficiency of Local Public Services: Does Size Matter?

No. 18,

published in: FinanzArchiv
Abstract
Similarly to western Germany in the 1960s and 1970s, the eastern part of Germany has experienced a still ongoing process of numerous amalgamations among counties, towns and municipalities since the mid-1990s. The evidence in the economic literature is mixed with regard to the claimed expenditure reductions and efficiency gains from municipal mergers. We therefore analyze the global efficiency of the municipalities in Saxony-Anhalt, for the first time in this context, using a double-bootstrap procedure combining DEA and truncated regression. This allows including environmental variables to control for exogenous determinants of municipal efficiency. Our focus thereby is on institutional and fiscal variables. Moreover, the scale efficiency is estimated to find out whether large units are necessary to benefit from scale economies. In contrast to previous studies, we chose the aggregate budget of municipal associations (“Verwaltungsgemeinschaften”) as the object of our analysis since important competences of the member municipalities are settled on a joint administrative level. Furthermore, we use a data set that has been carefully adjusted for bookkeeping items and transfers within the communal level. On the “eve” of a mayor municipal reform the majority of the municipalities were found to have an approximately scale-efficient size and centralized organizational forms (“Einheitsgemeinden”) showed no efficiency advantage over municipal associations.

Abstract
The article is part of a booklet edited by the Centre for Science Saxony-Anhalt - the Expert Platform “Demographic Change”. The booklet provides an overview on 15 research projects funded by the ministry of education of Saxony Anhalt. The IWH project analyzes aspects of demographic change in peripheral regions by means of Saxony Anhalt. In particular, the IWH research focus is on how citizens in peripheral regions will behave if the provision with social services of public interest is reduced. The article provides findings on the impact of primary schools closures on demographic change.

Size is not everything – The efficiency of municipal service provision in Saxony-Anhalt
Peter Haug, Annette Illy
Wirtschaft im Wandel,
No. 10,
2011
Abstract
The proponents of municipal area reforms – e.g. the recently completed reform in Saxony-Anhalt – expect that municipal amalgamations or centralized organizational forms save costs or increase the efficiency of local public service provision. This article examines the potential efficiency deficits of Saxony-Anhalt´s fragmented municipal structures on the eve of the crucial phase of the municipal reform. The results of a two-step DEA bootstrap procedure show that decentralized municipalities (“Verwaltungsgemeinschaften”) do not have to be significantly less efficient than centralized municipalities (“Einheitsgemeinden”). Furthermore, the results of the scale efficiency analysis suggest that the majority of Saxony-Anhalt´s communities already had an approximately efficient “firm size” – if the aggregated level of the municipal associations is examined. The relationship between scale efficiency and population is U-shaped. On the one hand, the results do not support the preservation of micro-municipalities or the formation of municipal associations with more than ten members. On the other hand, the results provide also no evidence for the necessity to reduce the number of towns and municipalities in Saxony-Anhalt from 1118 in 2004 to currently 219 – even if the looming population decline is taken into account.

School Closures and Population Decline in Saxony-Anhalt
Walter Hyll, Lutz Schneider
Wirtschaft im Wandel,
No. 6,
2011
Abstract
In rural areas school closures are often linked to a decline in population. Do school closures stimulate enhanced emigration? This paper analyses whether family migration is affected by the existence of primary schools. We conduct an empirical study for the East German province Saxony-Anhalt for the period 1991 to 2008. We find that primary schools significantly affect migration behaviour. After school closure municipalities experience a decrease in in-migration. Unexpectedly, controlling for cohort size, unobserved heterogeneity as well as for neighbourhood effects yields higher out-migration prior to school closure. Because the in-migration and the out-migration are of the same magnitude, in sum school closures have no observable impact on net-migration.

Retirement Income Systems in Middle and Eastern Europe: Between Change and Continuity
Martina Kämpfe, Ingmar Kumpmann
Wirtschaft im Wandel,
No. 5,
2011
Abstract
During the process of transition the Middle and Eastern European Countries introduced pension insurance plans on a Pay-as-you-go-basis following the Western European pattern. Rising financing problems caused by increasing unemployment as well as the demographic change led to the awareness of the need of reform. Hence in most of these countries mandatory funded pension schemes were established. This way proved to be costly since the actual active generation has to simultaneously finance both the new capital stock and the pensions of today’s retirees. The financial crisis revealed the vulnerability of funded pension plans. On this background especially Poland and Hungary partly roll back their reforms. In the Czech Republic whose pension plans were not harmed by the financial crisis the government plans to support private pension schemes increasingly. Bearing in mind the recent experiences it is recommendable to build up funded pension schemes very carefully and slowly. A further weakening of pension plans on a Pay-as-you-go basis is not advisable.

Ageing and Labour Markets: An Analysis on the effect of worker’s age on productivity, innovation and mobility
Lutz Schneider
Technische Universität Dresden. Dissertation,
2011
Abstract
The present study analyses the labour market effect of workers’ ageing. Explicitly, the impact of age on productivity and wages, on innovation as well as on mobility is explored empirically. The econometric analyses are based on firm and employment data from the Institute for Employment Research (IAB) and, thus, refer to the labour market of Germany. Regarding the productivity and wage effects of age the econometric results confirm a positive correlation between firm productivity and the share of middle-aged employees (41-50 years old) within the manufacturing sector. Hence, the results provide evidence of an inverted u-shaped age-productivity profile in this sector also found for other countries. Furthermore, age-wage and age-productivity profiles seem to follow unequal patterns. Compared to the group of the 15-30 and the 51 and above years old workers the group of middle-aged employees earn less than a productivity based wage scheme would require. In terms of age effects on innovativeness the micro-econometric analysis again reveals an inverted u-shaped profile. Workers aged around 40 years seem to act as key driver for innovation activities within firms. An additional finding concerns the impact of age diversity on innovation. The expected positive effect of a heterogeneous age structure is not confirmed by the data. With respect to labour market mobility results are in favour of a negative correlation between age and job mobility either in terms of changing professions or firms. The estimation of a multi equation model verifies that expected wages of older workers do not or only marginally increase due to job mobility, so, financial incentives to change jobs are very low. Yet, even after controlling the absent wage incentive older employees still remain more immobile than younger workers. Altogether, these results should not only be of academic interest but also informative for actors on the firm and the governmental level. Both sides are asked to cope with the challenges of demographic change. Only by maintaining productivity and innovativeness until old ages the necessary resources can be generated to preserve an economy’s prosperity even if the share of non-active population is increasing by demographic developments. Secondly, enhancing productivity is essential to ensure employability of older persons and to sustain the size of workforce even in the circumstances of an ageing economy.

Can Korea Learn from German Unification?
Ulrich Blum
IWH Discussion Papers,
No. 3,
2011
Abstract
We first analyze pre-unification similarities and differences between the two Germanys and the two Koreas in terms of demographic, social, political and economic status. An important issue is the degree of international openness. “Stone-age” type communism of North Korea and the seclusion of the population prevented inner-Korean contacts and contacts with rest of the world. This may create enormous adjustment costs if institutions, especially informal institutions, change. We go on by showing how transition and integration interact in a potential unification process based on the World Bank Revised Minimum Standard Model (RMSM) and on the Salter-Swan-Meade model. In doing so, we relate the macro and external impacts on an open economy to its macro-sectoral structural dynamics. The findings suggest that it is of utmost importance to relate microeconomic policies to the macroeconomic ties and side conditions for both parts of the country. Evidence from Germany suggests that the biggest general error in unification was neglecting these limits, especially limitations to policy instruments. Econometric analysis supports these findings. In the empirical part, we consider unification as an “investment” and track down the (by-and-large immediate to medium-term) costs and the (by-and-large long-term) benefits of retooling a retarded communist economy. We conclude that, from a South-Korean
perspective, the Korean unification will become relatively much more expensive than the German unification and, thus, not only economic, but to a much larger degree political considerations must include the tying of neighboring countries into the convergence process. We finally provide, 62 years after Germany’s division and 20 years after unification, an outlook on the strength of economic inertia in order to show that it may take much more than a generation to compensate the damage inflicted by the communist system.
