Vigorous upswing continues
Wirtschaft im Wandel,
No. 3,
2011
Abstract
The worldwide upswing has gained momentum since last autumn. The main cause for the high growth dynamics is a monetary policy that is very expansive not only in advanced economies, where the utilization rates for production capacities are mostly still low, but also in emerging market economies that in general have already recovered from the Great Recession.
The German economy participates in the worldwide upswing. Here the recovery is ahead of those in most other advanced economies. Both exports and domestic demand are strongly expanding. One reason for the high growth dynamics is that key interest rates are particularly low for Germany, as the ECB has to take into account that many euro area economies are much more fragile. In addition, Germany still benefits from the wage moderation and the labour market reforms in the past decade: employment is expanding strongly, and firms find many profitable investment projects.
Major risks for this forecast are structural problems of some advanced economies that had become visible during the Great Recession and are still unresolved (concerning the US housing market and the crisis of confidence in the fiscal sustainability of some euro area countries in particular). A further risk is the possibility of further oil price hikes due to political instability in North Africa and the Middle East.

On the Economic Architecture of the Workplace: Repercussions of Social Comparisons among Heterogeneous Workers
Oded Stark, Walter Hyll
Journal of Labor Economics,
No. 2,
2011
Abstract
We analyze the impact on a firm’s profits and optimal wage rates, and on the distribution of workers’ earnings, when workers compare their earnings with those of co-workers. We consider a low-productivity worker who receives lower wage earnings than a high-productivity worker. When the low-productivity worker derives (dis)utility not only from his own effort but also from comparing his earnings with those of the high-productivity worker, his response to the sensing of relative deprivation is to increase the optimal level of effort. Consequently, the firm’s profits are higher, its wage rates remain unchanged, and the distribution of earnings is compressed.

The Diffusion of Microgeneration Technologies. Assessing the Influence of Perceived Product Characteristics on Home Owners' Willingness to Pay

No. 3,

Abstract
This study presents empirical insight into willingness to pay (WTP) for microgeneration technologies and the relative influence of subjective consumer perceptions. First, we apply a double-bounded-contingent valuation method to elicit Irish home owners’ willingness to pay for micro wind turbines, wood pellet boilers, solar panels and solar water heaters. Utilizing findings from the adoption of innovation literature, in a second step, we assess the influence of different antecedents on WTP for each of the four technologies, including (1) home owners’ perception of product characteristics, (2) normative influences, and (3) socio demographic characteristics. Our results show that WTP varies significantly between the four technologies. More importantly, however, home owners’ hold different beliefs about the respective technologies, which significantly influence their WTP. The results provide valuable information for marketers and policy makers, aiming to promote microgeneration technologies more effectively in consumer markets.

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.

The Identification of Regional Industrial Clusters Using Qualitative Input-Output Analysis (QIOA)
Mirko Titze, Matthias Brachert, Alexander Kubis
Regional Studies,
No. 1,
2011
Abstract
The 'cluster theory' has become one of the main concepts promoting regional competitiveness, innovation, and growth. As most empirical applications focus on measures of concentration of one industrial branch in order to identify regional clusters, the appropriate analysis of specific vertical relations is developing in this discussion. This paper tries to identify interrelated sectors via national input-output tables with the help of minimal flow analysis (MFA). The regionalization of these national industry templates is carried out with the allocation of branch-specific production values on regional employment. As a result, the paper shows concentrations of vertical clusters in only 27 of 439 German Nomenclature des Unite´s Territoriales Statistiques (NUTS)-3 regions.

Human Capital Investment, New Firm Creation and Venture Capital
Merih Sevilir
Journal of Financial Intermediation,
No. 4,
2010
Abstract
This paper studies the relation between firm investment in general human capital, new firm creation and financial development for new firm financing, such as the existence of a venture capital industry. On one hand, firm investment in general human capital leads employees to generate new innovative ideas for starting their own firm. Since employees need a venture capitalist to start their new firm, firm investment in general human capital encourages the creation of venture capitalists by increasing the need for their services, such as providing advice and monitoring. On the other hand, as new firm financing becomes available, firms' willingness to invest in general human capital increases, and as a by-product, the creation of employee-founded and venture capital-backed new firms increases in the economy. Hence, our model provides a rational explanation for the emergence of new firms created by employees of established firms, which represents one of the most common type of new firms in many industries.

Arbeitskosteneffekte des Vorleistungsbezugs der Industrie an Dienstleistungen in Deutschland im Vergleich mit Frankreich und den Niederlanden – Eine Untersuchung mit der Input-Output-Methode. Gutachten im Auftrag des Instituts für Makroökonomie und Konjunkturforschung (IMK)

Abstract
As part of the outsourcing, industrial enterprises receive services in the production of their products which they used to provide on their own. As a result of the wage differentials between industry and service sector there is a shift in the burden labour costs have on industrial products. The study addresses the question of how significant this effect is. For this purpose the open static input-output model is used to analyse the degree of integration of the industry with its suppliers, the employment intensity of production and the labour cost differentials between the areas of production in Germany and in comparison with France and the Netherlands. The result of the labour cost analysis of industrial production shows - from a macroeconomic point of view - that the industry products have a smaller burden due to labour costs in Germany, France and the Netherlands, than the sectoral levels in the industry indicate. The difference in Germany is quantitative particularly strong pronounced. This saving in wage costs has increased somewhat after 2000. Crucial is that this discharge effect is achieved on the immediate wholesale inputs, that means in the first integration stage of industrial production.

Langfristige Wirkungen des Konjunkturpakets II am Beispiel der sächsischen Kommunen
Peter Haug
List Forum für Wirtschafts- und Finanzpolitik,
2010
Abstract
The article discusses primarily the potential long-term (supply-side) effects of the public investments subsidized by the German „Economic Stimulus Package II“. Considering the allocative aspects, especially the productivity and financing effects of publicly provided capital as well as the factor price effects of investment grants (municipalities are „lured to the concrete“) have to be taken into account. The theoretical problems are supported empirically by the subsidy practice in Saxony and its focus on local consumer goods (sports and leisure facilities) and on not directly economy-related educational facilities (kindergartens, primary schools). From a distributive point of view no interdependence between the financial strength (or weakness) of the municipalities and the amount of their ESPII-grants received could be confirmed empirically. Finally, with respect to the economic short-term stabilization effects of the program a significant increase of the municipal investments – although with a time lag - was found for Saxony.
