Rating-Software Welche Produkte nutzen wem?,
2007
Abstract
The Turbo-Rater was developed to give small and medium sized firm the ability to generate an fast and easy rating approximation themselves. During a 30 month research project a selection of firms in the german state of saxony were rated. All rating were evaluated in the project to develop a basis rating approach. The application is based on the Microsoft Excel plattform and aims to prepare firm, which did not participate in the research project, to prepaire themselves for the Changes following the Basel II accord.

Aid and Economic Freedom: An Empirical Investigation Using the Heritage Index
Tobias Knedlik, Franz Kronthaler
Journal of Development Perspectives,
No. 3,
2007
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature, the paper develops a simple panel regression model to evaluate the relationships. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that development aid is not contributing to economic freedom. It could not be shown that countries can be pushed towards economic freedom by aid conditions. The paper discusses explanations of the empirical findings.

Das Programm „Stadtumbau Ost“ und seine wirtschaftlichen Effekte für die beteiligten Städte
Claus Michelsen, Martin T. W. Rosenfeld
Wirtschaft im Wandel,
No. 6,
2007
Abstract
Political measures in the field of urban development have relevant impacts on the local and regional economy, for example on private investment, the value of real estate or the image of a city. An evaluation of national (federal) programs for the support of urban development would not be complete without considering these impacts. For the measures, which are supported by the federal program for support on “Urban Redevelopment in East Germany” (“Stadtumbau Ost”), the economic conditions of the supported cities have played, so far, only a minor role. One expression for this is that the measures for demolishing (“Rückbau”) were concentrated on quarters with prefabricated buildings. From the perspective of local and regional economic development, there have also been failures in the allocation of money for increasing the value of real estate (“Aufwertung”), as the article shows for the example of the state of Saxony.

Demographic development and its economic consequences

Wirtschaft im Wandel,
No. 6,
2007
Abstract
Within the next decades, East Germany will continue to face strong demographic challenges. In addition to shrinking, the ageing of population and labour force will more and more affect the economic development of the new Länder. Against this background, the question rises whether the shift of workforce age structure will influence growth and innovation potential as well as structural change. The IWH recently has focused on this topic widely ignored by the research literature so far. On the basis of selected methods and data, the economic impact of workforce ageing was empirically evaluated. The first issue concerns the impact of age on productivity. Based on two separate empirical investigations, the conclusion can be drawn that above a certain stage, age diminishes productivity. But higher levels of experience might partly compensate for this reduction. Secondly, the innovation effects of ageing have been analyzed. Again, significant age effects arise. Employees at the age of about 40 years turn out to be the most innovative part of the workforce. Furthermore, the analysis shows that engineers are particularly subject to age effects. A third study sheds light on the challenging consequences of ageing on entrepreneurship potential. Hence, independently of the increasing problem of skill shortages, ageing itself will unfavourably affect growth, innovation and structural change. Though political options are limited due to the more or less fixed demographic trends, appropriate instruments regarding economic, family and education policy might lower the identified age effects.

The role of banking portfolios in the transmission from the currency crises to banking crises - potential effects of Basel II
Tobias Knedlik, Johannes Ströbel
IWH Discussion Papers,
No. 21,
2006
Abstract
This paper evaluates the potential effects of the Basel II accord on preventing the transmission from currency crises to financial crises. By analyzing the case study of South Korea, it shows how mismatches on banks’ balance sheets were the primary cause for such a transmission, and models how Basel II would have affected those balance sheets. The paper shows that due to South Korea’s positive credit rating in the months leading up to the crisis, the regulatory capital reserves under Basel II would have been even lower than those under Basel I, and that therefore Basel II would have had adverse effects on the development of the crisis. In the second part, the article analyses whether the behavior of rating agencies has changed since their failure to predict the Asian crisis. The paper finds no robust econometric evidence that rating agencies have started to take micromismatches into account when assigning sovereign ratings. Thus, given the current approach of credit rating agencies, we have reservations concerning the effectiveness of Basel II to prevent the transmission from currency crises to banking crises, both for the case of South Korea and for potential future crises.

Too old to work? The impact of age on productivity
Lutz Schneider
Wirtschaft im Wandel,
No. 11,
2006
Abstract
Due to the public debate on the raising legal re-tirement age in Germany labor market research has recently focused on an explanation of the low labor market participation rate of elders. In the economic discussion the low participation is pri-marily explained by a supposed imbalance of la-bor costs and returns for old workers. Whereas wages rise with increasing age, the individual productivity seems to fall beyond a certain age. Gerontological research supports this view, since it documents an age-driven decline of physical and certain mental abilities. The study empirically evaluates the thesis of a diminishing individual productivity at higher ages. The analysis is done on the basis of a new dataset for German firms of the manufacturing sector. Using these data the effect of the employee’s age on a firm’s productiv-ity is estimated and conclusions on the job per-formance of workers at different ages are drawn. The performed cross-section-regressions of the years 2003 and 2000 indicate an inverted u-shaped age-productivity-profile. The 25-44 year olds turn out to be the most productive, the share of the over 44 year old workers seems to dampen productivity. However the 15-24 age group makes the lowest productivity contribution. Moreover a positive effect of firm-related experience can be found. Due to elders’ higher stock of firm specific human capital this might at least partly compen-sate the unfavorable effects of aging.
From a political perspective these findings sup-port the view, that an increasing legal retirement age will not automatically lead to a remarkable extension of the labor demand for older people. In addition to legal aspects the wage schemes and the actual productivity profiles in higher age have to be linked more closely together.

Mikroökonometrische Evaluation der ökonomischen Wirkungen betrieblicher Mitbestimmung - Möglichkeiten und Grenzen des Matching-Ansatzes
Birgit Schultz
Jahrbücher für Nationalökonomie und Statistik,
No. 5,
2006
Abstract
The evaluation of economic effects of workers participation is not simple from the methodical point of view because of specific characteristics of establishments with works councils. Especially recent studies show contradictory results. In this study problems are pointed out, discussed, and options for solution are presented on the example of workers participation in East German establishments of industry and construction by the IAB-Establishment Panel.
An optimal matching-algorithm which supplies good matching-results for small samples to assign 'statistical establishment-twins' is applied. But by reason of very short primarily spells it can only calculate short time effects. Therefore, the matching method is additionally used to construct longer observation periods. By this new application establishments with recently founded works councils are matched with so called 'proxy establishments' with existing works councils. As a result short observation periods are prolonged and information about long-term effects can be given.
The effects on productivity, profitability and qualification level of employees show neither in short-term nor in long-term a significant impact on workers' participation.

Microeconometric Evaluation and the Selection Bias – A practical Survey of Nonparametrical Solution Methods
Eva Reinowski
Zeitschrift für Evaluation 2,
No. 2,
2006
Abstract
The application of evaluation strategies becomes more important in various fields of study. The problem of self-selection associated with microeconomic evaluation can be solved in different ways, but nonparametrical solutions are most popular. The study gives an overview of nonparametrical solution methods for this problem. The aim is to close the gap between introductory and the more sophisticated literature and to give some practical guidance for the choice of the appropriate method for empirical application. The assumptions as well as advantages and drawbacks for empirical application and the requirements to the data base are described for every approach. It becomes clear that there is no ‘magic bullet’. For an unbiased estimation the assumptions have to be fulfilled and the data at hand must be compatible with the respective method.

Vielfältigkeit eines Hybridberufes: Mechatronikfacharbeiter nach der Ausbildung
Simone Scharfe, K. Tautenhahn
External Publications,
No. 8,
2006
Abstract
In the period from 2002 to 2004, 302 skilled workers successfully concluded their education as a mechatroniker, microtechnologist, chemical laboratory assistant, physics laboratory assistant or varnish laboratory assistant within the scope of the model project "compound education in new professions of high technology" which was initiated by the Saxonian State Ministry of Economy and Labor. The model project and the scientific monitoring were promoted from means of the European Social Fund and complementary state means of the Free State of Saxony.
Some months after the completion of their education, the graduates were questioned by the scientific monitoring about different aspects concerning the model project and its evaluation, points of interests have for example been:
§ the retrospective assessment of the education and the model project,
§ the estimation of their chances in the job market,
§ the professional whereabouts as well as
§ the evaluation of their knowledge in terms of its suitability for daily use.
In this article, the results of the last both points in the view of the mechatroniker, which are the biggest group in the model project with 180 graduates, are picked out as a central theme. Because the mechatronikers should combine the branches of the mechanics and the electronics in the second part of the result representation the actual operational areas of the former trainee are examined.
ich hätte evtl. einiges anders formuliert: (der Satzbau klingt sonst so eingedeutscht)
The article mainly refers to the last two points. Also, the view is limited to the results of the mechatroniker. Covering 180 graduates, it has been the largest group within the model project.
The intention of the new occupational image of the mechatroniker was a bridging of mechanics and electronics. Therefore, it is examined in the second part of this article, to which extend this bridging is reflected in the actual operational areas of the former trainees.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.
