Abstract
Growth in advanced economies is essentially driven by innovation activities. The question rises from a demographic point of view as to 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 U-shaped pattern, it peaks at the age of about 40 years. A separate estimation shows that technicians and engineers age seems to be particularly relevant.

Determinants of International Fragmentation of Production in the European Union

IWH Discussion Papers,
No. 15,
2007
Abstract
The last decades were characterized by large increases in world trade, not only in absolute terms, but also in relation to world GDP. This was in large parts caused by increasing exchanges of parts and components between countries as a consequence of international fragmentation of production. Apparently, greater competition especially from the Newly Industrializing and Post-Communist Economies prompted firms in ‘high-wage’ countries to exploit international factor price differences in order to increase their international competitiveness. However, theory predicts that, beside factor price differences, vertical disintegration of production should be driven by a multitude of additional factors. Against this background, the present paper reveals empirical evidence on parts and components trade as an indicator for international fragmentation of production in the European Union. On the basis of a panel data approach, the main explanatory factors for international fragmentation of production are determined. The results show that, although their influence can not be neglected, factor price differences are only one out of many causes for shifting production to or sourcing components from foreign countries.

Threshold for employment and unemployment. A spatial analysis of German RLM's 1992-2000

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.

The unemployment-growth relationship in transition countries
Hubert Gabrisch, Herbert Buscher
IWH Discussion Papers,
No. 5,
2005
Abstract
Does the disappointingly high unemployment in Central and East European countries reflect non-completed adjustment to institutional shocks from transition to a market economy, or is it the result of high labour market rigidities, or rather a syndrome of too weak aggregate demand and output? In the case of transitional causes, unemployment is expected to decline over time. Otherwise, it would pose a challenge to the European Union, particular in case of accession countries, for it jeopardizes the ambitious integration plans of, and may trigger excessive migration to the Union. In order to find out which hypothesis holds 15 years after transition has started, we analyze the unemploymentgrowth dynamics in the eight new member countries from Central-Eastern Europe. The study is based on country and panel regressions with instrument variables (TSLS). The results suggest to declare the transition of labour markets as completed; unemployment responds to output and not to a changing institutional environment for job creation. The regression coefficients report a high trend rate of productivity and a high unemployment intensity of output growth since 1998. The conclusion is that labour market rigidities do not to play an important role in explaining high unemployment rates. Rather, GDP growth is dominated by productivity progress, while the employment relevant component of aggregate demand is too low to reduce substantially the high level of unemployment.

Possible effects of demographic change - An overview
Gunter Steinmann, Olaf Fuchs, Sven Tagge
Wirtschaft im Wandel,
No. 15,
2002
Abstract
One of the more important influences shaping the future economic conditions of the highly industrialized countries is the decline and aging of their population. The article is a comprehensive survey of the impact of this development on key economic variables and the institutions of the welfare state. While the overall consequence of the aging process on productivity growth is more likely to be negative, there are also some offsetting forces like the increase in the capital intensity. The institutions of the welfare state, which are based on intergenerational transfers, will have to be reformed, in order to bring them in line with the demographic process. The prediction of a decrease in the rate of unemployment as a consequence of a declining labor force is according to our analysis not justified.

Germany: Cyclical Improvement not Until the End of the Year
Wirtschaft im Wandel,
No. 12,
2001
Abstract
During the second quarter of 2001 German overall production stagnated. Weak global development muddied the economic prospects of firms and prevented them from rising their output and their investment activities. In 2001 gross national product will only increase by 1%; the number of unemployed will be higher than expected. Nevertheless, we advise against an increase in public expenditure that aims at stimulating the economy. Anyhow, growing public deficits, caused by cyclical movements, should be accepted. In order to increase employment labour market reforms become more urgent.
In East Germany, currently even a decline in gross national product cannot be excluded. After the first period of restructuring, which has been accompanied by structural problems, cyclical movements become more important. In addition, economic stagnation burdens labour markets. Nonetheless trying to stimulate the East German economy by government spending programmes does not seem to be a viable strategy. From the cyclical point of view they are not very efficient and concerning structural problems they are no solution.
