Abstract
The development and successful introduction of new products is a fundamental feature of a modern knowledge society. After completion of the retrieving technological renewals in East Germany, businesses in the newly-formed German states have to stand up to the competition for marketable concepts and ideas. In doing so, the structural particularities on the strength of transformation are still in force and besides, the embedding of East Germany between high-tech in the West and catching up countries in the East constitutes an additional challenge. This article outlines the innovation activities of East German companies and pursues in the framework of an multivariate analysis to follow up intra-corporate determining factors for product innovations The empirical analysis, employing the IAB establishment panel, shows an active share of innovation participation of companies belonging to the manufacturing industry in East Germany during the years 2002 and 2003. The proportion of companies with product innovation in the newly-formed German states even lies slightly above the reference value for West Germany. Especially companies with an own Research and Development (R&D) department are introducing new products twice as much as companies without an R&D division. The regression analysis proves that own R&D represents the strongest driving force for product innovations in regard to input factors. Moreover, continuing operational education can also be attested a positive impact on innovation activities and emphasizes concurrently the meaning of long-life learning. In reference to business specific characteristics, it stands out that foreign equity participation imposes a significant negative impact of on product innovations. This result, deserving further analysis, indicates the phenomenon of so-called subcontracting.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
No. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

Effectiveness of Competition Law: A Panel Data Analysis
Franz Kronthaler
IWH Discussion Papers,
No. 7,
2007
Abstract
The paper explores what macroeconomic factors can tell us about the effectiveness of recently enacted national competition laws. Qualitative evidence suggests that numerous countries fall short in implementing competition law. Furthermore, there seems to be significant differences between countries. To examine what factors might contribute to the explanation of effectiveness of competition law panel regression analysis is used. The results indicate that the level of economic development matters, however the institutional learning curve is also relevant. Furthermore, larger countries should be more concerned with competition advocacy activities than smaller countries and it seems to be the case that the problem of capture of competition law is serious in countries with high levels of corruption.

Local Government Control and Efficiency of the Water Industry: An Empirical Analysis of Water Suppliers in East Germany
Peter Haug
IWH Discussion Papers,
No. 3,
2007
Abstract
The paper deals with the effects of local governments’ interference with business affairs of publicly owned utilities. A partial model is presented to illustrate the consequences of “democratic control” for the public managers’ effort and the efficiency of local public production. To check the theoretical results empirically, a two-stage data envelopment analysis (DEA) is carried out for a sample of East German water suppliers. The organisational form is used as a measure for the degree of municipal control. The results of the OLS- and Tobit regression indicate an efficiency-enhancing effect of organisational forms with less distinctive control options for local politicians.

Alterung und technologisches Innovationspotential : Eine Linked-Employer-Employee-Analyse
Lutz Schneider
IWH Discussion Papers,
No. 2,
2007
Abstract
Growth in advanced economies is essentially driven by innovation activities. From a demographic point of view the question rises, whether the trend of an ageing workforce will affect the innovation capacities of these economies. To answer this question, the paper examines on the basis of a German linked-employer-employee-dataset, whether an older workforce lowers a firm’s potential to generate product innovations. The empirical approach is based on an Ordered-logit regression model, relating a firm’s innovation potential to the age composition of its employees. The analysis provides evidence of significant age effects. The estimated age-innovation-profile follows an inverted-ushaped pattern, it peaks at the age of about 40 years. A separate estimation shows, that the technician’s and engineer’s age seems to be particularly relevant.

Mit 55 zum alten Eisen? Eine Analyse des Alterseinflusses auf die Produktivität anhand des LIAB
Lutz Schneider
Zeitschrift für Arbeitsmarktforschung,
No. 1,
2007
Abstract
"Against the background of an aging labor force in Germany and insufficient job opportunities for older people, the paper raises the question as to how age affects the productivity of workers. Due to opposite developments of certain human abilities across the life span, gerontological research supports the hypothesis of an inverted u-shaped age-productivity profile. Middle aged workers are supposed to achieve the highest productivity level, whereas both young and old employees should show lower productivity levels. The analysis is carried out on the basis of a new linked employer-employee dataset of the Institute for Employment Research (LIAB). Within a production function framework it is tested econometrically whether the age composition of a firm's workforce affects its productivity and if so in what way. The regressions are carried out separately for the manufacturing and the service sectors. The cross-section estimations of the year 2003 reveal a positive correlation between firm productivity and the share of middle-aged employees (35-44 years old). Furthermore, in the manufacturing sector, a negative correlation between productivity and the proportion of the youngest age group (15-24 years old) can be seen. Thus the results provide evidence of an inverted u-shaped age-productivity profile in this sector. In the service sector, in contrast, the share of the youngest workers seems to increase productivity compared to the reference group of the 55-64 year-old employees.

Threshold for employment and unemployment. A spatial analysis of German RLM's 1992-2000
Christian Dreger, Reinhold Kosfeld
External Publications,
2006
Abstract
Changes in production and employment are closely related over the course of the business cycle. However, as exemplified by the laws of Verdoorn (1949, 1993) and Okun (1962, 1970), thresholds seem to be present in the relationship. Due to capacity reserves of the firms, output growth must exceed certain levels for the creation of new jobs or a fall in the unemployment rate. While Verdoorn's law focuses on the growth rate of output sufficient for an increase in employment, in Okun's law, the fall in the unemployment rate becomes the focus of attention. In order to assess the future development of employment and unemployment, these thresholds have to be taken into account. They serve as important guidelines for policymakers. In contrast to previous studies, we present joint estimates for both the employment and unemployment threshold. Due to demographic patterns and institutional settings on the labour market, the two thresholds can differ, implying that minimum output growth needed for a rise in employment may not be sufficient for a simultaneous drop in the unemployment rate. Second, regional information is considered to a large extent. In particular, the analysis is carried out using a sample of 180 German regional labour markets, see Eckey (2001). Since the cross-sections are separated by the flows of job commuters, they correspond to travel-to-work areas. Labour mobility is high within a market, but low among the entities. As the sectoral decomposition of economic activities varies across the regions, the thresholds are founded on a heterogeneous experience, leading to more reliable estimates.The contribution to the literature is twofold. First, to the best of our knowledge, no previous paper has investigated a similar broad regional dataset for the German economy as a whole before. By using a panel dataset, information on the regional distributions around the regression lines as well as theirs positional changes is provided for each year. Second, the methods applied are of new type. They involve a mixture of pooled and spatial econometric techniques. Dependencies across the regions may result from common or idiosyncratic (region specific) shocks. In particular, the eigenfunction decomposition approach suggested by Griffith (1996, 2000) is used to identify spatial and non-spatial components in regression analysis. As the spatial pattern may vary over time, inference is conducted on the base of a spatial SUR model. Due to this setting, efficient estimates of the thresholds are obtained. With the aid of a geographic information system (GIS) variation of the spatial components can be made transparent. With Verdoorn’s and Okun’s law the figures show some significant patterns become obvious over time. In respect to Verdoorn’s law, for instance, a stripe of high values in the north-western part from Schleswig-Holstein via Lower Saxony and North Rhine Westfalia to Rhineland Palatinate is striking in all years but 1994 and 1995. In most periods the spatial component is likewise concentrated in Saxony. Clusters of low values can be found in northern Bavaria and, in some periods, in Thüringen and Mecklenburg-Vorpommern. Other parts of Germany appear to be more fragmented consisting of relative small clusters of low, medium and high values of the spatial component. With Okun’s law some changing spatial patterns arise. In all, spatially filtering provides valuable insights into the spatial dimensions of the laws of Verdoorn and Okun.

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.

The Effects of Shared ATM Networks on the Efficiency of Turkish Banks
H. Evren Damar
Applied Economics,
No. 6,
2006
Abstract
This study investigates whether forming shared ATM networks has yielded positive benefits for banks in Turkey by increasing their productive efficiency. Using a Data Envelopment Analysis (DEA) approach, pure technical and scale efficiency scores of Turkish banks are estimated and analysed for the period 2000–2003. The results suggest that although it is possible to realize positive effects through ATM sharing arrangements, there are multiple factors that determine which banks realize such benefits. The geographical distribution of shared ATMs between urban and rural markets and the level of competition between banks within urban areas are shown to be important determinants of differences in bank efficiency. This discrepancy between the gains associated with ATM sharing may have important implications concerning the adoption and sharing of new technology by banks in developing countries.

No. 13,
2006
Abstract
Against the background of an aging labor force in Germany and insufficient job chances of elders the paper rises the question, whether various age groups differ in their productivity levels. The analysis is carried out on the basis of a new linked employer-employee dataset for the years of 2000 and 2003. With respect to the manufacturing sector the cross section regressions provide unambiguous evidence for a higher productivity of mid-age-workers. In contrast the effects regarding the service sector turn out to be of less significance.
