No. 6,

Abstract
While the long-run relation between money and inflation as predicted by the quantity theory is well established, empirical studies of the short-run adjustment process have been inconclusive at best. The literature regarding the validity of the quantity theory within a given economy is mixed. Previous research has found support for quantity theory within a given economy by combining the P-Star, the structural VAR and the monetary aggregation literature. However, these models lack precise modelling of the short-run dynamics by ignoring interest rates as the main policy instrument. Contrarily, most New Keynesian approaches, while excellently modeling the short-run dynamics transmitted through interest rates, ignore the role of money and thus the potential mid-and long-run effects of monetary policy. We propose a parsimonious and fairly unrestrictive econometric model that allows a detailed look into the dynamics of a monetary policy shock by accounting for changes in economic equilibria, such as potential output and money demand, in a framework that allows for both monetarist and New Keynesian transmission mechanisms, while also considering the Barnett critique. While we confirm most New Keynesian findings concerning the short-run dynamics, we also find strong evidence for a substantial role of the quantity of money for price movements.

Climate Innovation - The Case of the Central German Chemical Industry
Wilfried Ehrenfeld
IWH Discussion Papers,
No. 2,
2012
Abstract
In this article, we describe the results of a multiple case study on the indirect
corporate innovation impact of climate change in the Central German chemical
industry. We investigate the demands imposed on enterprises in this context as well as the sources, outcomes and determining factors in the innovative process at the corporate level. We argue that climate change drives corporate innovations through various channels. A main finding is that rising energy prices were a key driver for incremental energy efficiency innovations in the enterprises’ production processes. For product innovation, customer requests were a main driver, though often these requests are not directly related to climate issues. The introduction or extension of environmental and energy management systems as well as the certification of these are the most common forms of organizational innovations. For marketing purposes, the topic of climate change was hardly utilized so far. As the most important determinants for corporate climate innovations, corporate structure and flexibility of the product portfolio, political asymmetry regarding environmental regulation and governmental funding were identified.

Industrielle Güterstrukturen Ostdeutschlands im Wandel
Udo Ludwig, Brigitte Loose
Wirtschaft im Wandel,
No. 2,
2012
Abstract
In der Phase des marktwirtschaftlichen Umbaus standen die ostdeutschen Industriebetriebe auch vor der Wahl einer marktgerechten Produktstrategie. Sollten sie auf Spezialisierung oder Vielfalt des Angebots setzen? Der Beitrag analysiert die Ergebnisse in den Jahren 1997 und 2005 auf der Branchenebene im Ost-West-Vergleich und blickt auf die Situation am Ende der DDR zurück. Anhand von Mikrodaten der amtlichen Statistik werden die Branchenherkunft der erzeugten Produkte für die Jahre 1997 und 2005 ermittelt, auf Basis dieser Angaben Spezialisierungsgrade für Branchen und Gütergruppen berechnet und ausgewertet. Die Autoren kommen zu dem Schluss, dass sich in weniger als zwei Jahrzehnten die Grobstruktur der in Ostdeutschland hergestellten Industriegüter deutlich an die Verhältnisse in Westdeutschland angenähert hat. So bilden inzwischen in Ost- wie in Westdeutschland dieselben Gütergruppen die Top Fünf. Unterschiede bestehen allerdings weiterhin in der Rangfolge der Gütergruppen und in den Abständen innerhalb der Rangfolge.

Size is not everything – The efficiency of municipal service provision in Saxony-Anhalt
Peter Haug, Annette Illy
Wirtschaft im Wandel,
No. 10,
2011
Abstract
The proponents of municipal area reforms – e.g. the recently completed reform in Saxony-Anhalt – expect that municipal amalgamations or centralized organizational forms save costs or increase the efficiency of local public service provision. This article examines the potential efficiency deficits of Saxony-Anhalt´s fragmented municipal structures on the eve of the crucial phase of the municipal reform. The results of a two-step DEA bootstrap procedure show that decentralized municipalities (“Verwaltungsgemeinschaften”) do not have to be significantly less efficient than centralized municipalities (“Einheitsgemeinden”). Furthermore, the results of the scale efficiency analysis suggest that the majority of Saxony-Anhalt´s communities already had an approximately efficient “firm size” – if the aggregated level of the municipal associations is examined. The relationship between scale efficiency and population is U-shaped. On the one hand, the results do not support the preservation of micro-municipalities or the formation of municipal associations with more than ten members. On the other hand, the results provide also no evidence for the necessity to reduce the number of towns and municipalities in Saxony-Anhalt from 1118 in 2004 to currently 219 – even if the looming population decline is taken into account.

Labor Demand During the Crisis: What Happened in Germany?
Claudia M. Buch
IZA. Discussion Paper No. 6074,
2011
Abstract
In Germany, the employment response to the post-2007 crisis has been muted compared to other industrialized countries. Despite a large drop in output, employment has hardly changed. In this paper, we analyze the determinants of German firms’ labor demand during the crisis using a firm-level panel dataset. Our analysis proceeds in two steps. First, we estimate a dynamic labor demand function for the years 2000-2009 accounting for the degree of working time flexibility and the presence of works councils. Second, on the basis of these
estimates, we use the difference between predicted and actual employment as a measure of labor hoarding as the dependent variable in a cross-sectional regression for 2009. Apart from total labor hoarding, we also look at the determinants of subsidized labor hoarding through short-time work. The structural characteristics of firms using these channels of adjustment differ. Product market competition has a negative impact on total labor hoarding but a positive effect on the use of short-time work. Firm covered by collective agreements hoard less labor overall; firms without financial frictions use short-time work less intensively.

Effects of Local Public Investment into Infrastructure for Tourism: The Example of Saxony
Albrecht Kauffmann
Jahrbuch für Regionalwissenschaft,
No. 1,
2011
Abstract
The mass of investments into infrastructure for tourism in the so-called “New States” (Neue Länder) of the Federal Republic of Germany after 1990 was huge. They were aimed to the maintenance and recovery, respectively of competitiveness of traditional destinations, as well as to promote service-oriented structural change in industrial wastelands. A big part of these investments was supported by funds of the so called “Joint Task for Improving the Regional Economic Structure”. We analyse the effects of local public investment into infrastructure for tourism supported by investment grants on the local employment in accommodation and food service activities in the state of Saxony. The results provide evidence for correlations between special types of investment in the time period 2000–2007 and the development of employment in hospitality industry. However, this is subject to some requirements, such as the existence of complementary factors, or an existing regional touristic tradition as well.

Entrepreneurial Opportunity and the Formation of Photovoltaic Clusters in Eastern Germany
Matthias Brachert, Christoph Hornych
R. Wüstenhagen, R. Wuebker (Hrsg.), Handbook of Research on Energy Entrepreneurship,
2011
Abstract
The aim of this paper is to explain the evolution of the spatial structures of one particular type of renewable energy in Germany – the photovoltaic (PV) industry. We first demonstrate how environmental movements have contributed to institutional change and government action, leading to changes in the legal and regulative structure in Germany. We describe how these changes opened up a window of locational opportunity (WLO), thus combining the WLO concept with the entrepreneurial opportunity concept. As market entries occurred mainly in Eastern Germany, the paper also explores the factors leading to a concentration of economic activity related to the new PV industry in this part of the country. Based on the WLO concept, we combine this framework with the industrial dynamics literature by Klepper (2007) and illustrate the spatial evolution of the PV industry.

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.
