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.

Interregional equalization policy in focus: Donor regions and beneficiary regions and their economic performance
Gerhard Heimpold, Peter Franz
Wirtschaft im Wandel,
No. 11,
2006
Abstract
The future of the interregional equalization policy in Germany is discussed intensively at present. While in the past the interest of equalization policy was focussed primarily on the regions which benefit from interregional equalization policy (beneficiary regions) and the effects obtained there, recently the view is directed also toward the regions which bear the fiscal burden of the equalisation policy (donor regions). Concerning the donor regions, a fear of growth-absorbing withdrawal effects exists, which gives reason in view of declining economic growth rates on the national level to think about the future of interregional equalization policy. The IWH contributed to this debate together with two project partners by an investigation, which was accomplished on behalf of the Federal Office for Building and Regional Planning. The following findings will show the economic performance of the donor regions (exclusively West German regions) and of the beneficiary regions (all East German regions and a few West German regions) and their changing economic growth patterns. Concerning the level of economic performance, measured by means of the gross domestic product (GDP) per capita, as expected, the donor regions, consisting of West German regions, in the period 1992-2003 altogether show an above average GDP per capita. In contrast, the beneficiary regions, both the East German and (less strongly) the West German show a GDP per capita below average. Concerning the development of the economic performance, which was measured on the basis of the relative GDP per capita (GDP per capita of the region concerned in relation to the national average), the East German beneficiary regions could catch up in the first period (1992-1998) strongly. This catching up process, however, clearly slowed down in the second period 1998-2003. Like a mirror-image the lead of the donor regions regarding GDP per capita in relation to the national average became smaller. But after 1998 many West German donor regions regained their growth dynamics. Additionally the contributions of the regions to the absolute increase of the GDP in the period 1998-2003 were investigated: 30 of 271 regions have a share of around 50% in the overall GDP increase, 28 of them located in West Germany, and 21 of them donor regions. This in mind, the policy should further provide and secure favourable development conditions for those regions, which contribute at most to the increase of the overall economic performance and thus create the economic base for the interregional equalization policy.

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.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan
East-West Journal of Economics and Business,
2006
Abstract
This research assesses the firm-specific reasons for lower producitivity levels between West and East German firms. The study is based on a unique data-base generated by field-work in the two particularly important sectors of machinery manufacturers and furniture manufacturers. Our results suggest that the quality of human capital plays an important role in explaining lower productivity levels, as well as particularly networking activities, and the use of modern technologies for communication. Classifying those as management-functions beyond the organisation of the production process itself, we identify management deficits as the main specific determinants of productivity gaps between West and East German firms.

The relationship between unemployment and output in post-communist countries
Hubert Gabrisch, Herbert Buscher
Post-Communist Economies,
2006
Abstract
Unemployment is still disappointingly high in most Central and East European countries, and might be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or it may be caused by high labour market rigidity, or aggregate demand that is too weak. In this paper we have investigated the dynamics of unemployment and output in those eight post-communist countries, which entered the EU in 2004. We used a model related to Okun’s Law; i.e. the first differences in unemployment rates were regressed on GDP growth rates. We estimated country and panel regressions with instrument variables (TSLS) and applied a few tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regarded as completed since unemployment responds to output changes and not to a changing institutional environment that destroys jobs in the state sector. The regression coefficients have demonstrated that a high trend rate of productivity and a high unemployment intensity of output growth have been occurring since 1998. Therefore, we conclude that labour market rigidities do not play an important role in explaining high unemployment rates. However, GDP growth is dominated by productivity progress and the employment-relevant component of aggregate demand is too low to reduce the high level of unemployment substantially.

Productivity and employment effects of staff participation
Ulrich Blum
Wirtschaft im Wandel,
No. 9,
2006
Abstract
Die Beteiligung der Mitarbeiter am Kapital und der den Erträgen der Unternehmen fand in den vergangenen Monaten eine erhöhte Aufmerksamkeit in der Wirtschaftspresse. Hierfür gibt es eine Reihe von Ursachen: der positive Beitrag zu Produktivität und Beschäftigung, die verbesserte Entlohnung und die erhöhte Motivation der Arbeitnehmer und schließlich die Stabilisierung der Finanzierung vor allem bei mittelständischen Unternehmen vor dem Hintergrund von Basel II, also den Eigenkapitalrichtlinien für Banken, die damit ihre Ausleihungen risikoadäquat bepreisen werden. Unter dem Begriff der Mitarbeiterbeteiligung findet sich eine Fülle alternativer Gestaltungen, die davon abhängen, welche Rechtsform das Unternehmen besitzt, ob nur Erträge ausgeschüttet werden sollen oder ob eine Beteiligung am Kapital – und hier entweder beim Eigen- oder beim Fremdkapital erfolgen soll. Die damit auftretende Fülle von Ausprägungen macht es statistisch enorm schwierig, klare Nachweise für Vorteile zu führen, vor allem aber nachzuweisen, wie die vermuteten Wirkungsmechanismen ablaufen. In diesem Beitrag wird die Relevanz von Mitarbeiterbeteiligungen für den Unternehmenserfolg aus Sicht der Literatur und zwei eigenen Forschungsbeiträgen dargestellt, um Aussagen über deren wirtschaftliche Wirkungen zu gewinnen und abzuleiten, ob sie grundsätzlich geeignet sind, Arbeitnehmer an Erträge aus Wissen und Kapital heranzuführen. Tatsächlich läßt sich zeigen, daß die Strukturen von Unternehmen mit Mitarbeiterbeteiligungen, vor allem im Mittelstand, erheblich von denen ohne derartige Angebote abweicht. Bei gegebenem Wirtschaftszweig sind sie in erfolgreicheren Märkten tätig als der Durchschnitt der Unternehmen. Die Erfolgsbeiträge bei den Unternehmern sind schwer zu messen, weil sie verteilt werden, und nicht allein als erhöhte Gewinne erscheinen. Vielmehr fließen diese Produktivitätsgewinne auch den Kunden durch verbesserte Qualität zu, was wiederum risikosenkend wirkt, oder sie erhöhen den Wert des Unternehmens.
