Leader of the pack? German monetary dominance in Europe prior to EMU

In this paper, the monetary policy independence of European nations in the years before European Economic and Monetary Union (EMU) is investigated using cointegration techniques. Daily data is used to assess pairwise relationships between individual EMU nations and ‘lead’ nation Germany, to assess the hypothesis that Germany was the dominant European nation prior to EMU. By and large our econometric investigations support this hypothesis, and lead us to conclude that the only European nation to lose monetary policy independence in the light of monetary union was Germany. Our results have important policy implications. Given that the loss of monetary policy independence is generally viewed as the main cost of monetary unification, our findings suggest a reconsideration of the costs and benefits of monetary integration. A country can only lose what it has, and in Europe the countries that joined EMU — spare Germany — apparently did not have much to lose, at least not in terms of monetary independence. Instead, they actually gained monetary policy influence by getting a seat in the ECB's governing council which is responsible for setting interest policy in the euro area.     

Does the dispersion of unit labor cost dynamics in the EMU imply long-run divergence?

Using unit labor cost (ULC) data from Euro area countries as well as US States and German Länder we investigate inflation convergence using different approaches, namely panel unit root tests, cointegration tests and error-correction models. All in all we cannot reject convergence of ULC growth in EMU. However, country-specific deviations from the rest of the currency union are much more pronounced and much more persistent in Europe than in the US or Germany. This holds before and after the introduction of the common currency. Hence, asymmetric shocks in the future might take a long time to dissipate.     

The Collaboration of Innovation Intermediaries and Manufacturing Firms in the Markets for Technology

Many manufacturing firms have opened up their product innovation processes and actively transfer knowledge with external partners in the markets for technology. However, the markets for technological knowledge have remained inefficient in comparison with the markets for most products. To reduce some of the market inefficiencies, manufacturing firms may collaborate with innovation intermediaries, which are defined as organizations that act as agents or brokers in the innovation process between two or more parties. These innovation intermediaries comprise different service providers ranging from consulting companies to Internet marketplaces for technology. In light of an increasing importance of intermediary services in the context of open innovation, this paper specifically focuses on the collaboration of manufacturing firms and innovation intermediaries, which may be critical for the success of intermediary services. Based on new interview data from 30 innovation intermediaries and 30 European manufacturing firms, this paper examines the question of how innovation intermediaries and manufacturing firms collaborate concerning the following issues, which emerged as the key themes from the interviews: potential of intermediation, roles of intermediaries, types of intermediation, drivers of intermediation, complementarity of intermediation, compensation of intermediation, and the importance of repeated collaborations. The findings indicate how manufacturing firms may reduce their transaction costs in technology markets by collaborating with intermediaries. However, intermediary services can only be regarded as a complement rather than a substitute of manufacturing firms' internal activities of managing technology transfer. Thus, manufacturing firms need sufficient internal capabilities for managing technology transfer, such as absorptive capacity and desorptive capacity.     

Techno-ökonomische Bewertung von Energie-Autarkie für die Energieversorgung von Einfamilienhäusern

Many consumers currently follow the idea of energy self-sufficiency and try to contribute to meet their energy needs in order to become independent and self-sufficient from the central power supply system. In order to achieve load-oriented energy self-sufficiency the provision of energy must cover the full energy demand at any time. Against this background, in this paper the costs and potentials of a load-oriented energy self-sufficiency of single-family homes are analysed. Thereby it is differentiated between electricity-, heat- and energy self-sufficiency. The modelling is carried out with the simulation environment ?Polysun Designer“ which allows a high temporal dynamic simulation of the annual energy demand and supply.The results show that, within the investigated supply variations, the highest levels of energy self-sufficiency can be achieved by an energy supply system completely based on electricity using a combination of PV; heat pump and battery storage. Depending on the building standard, a maximum of 45 (existing buildings) and 71?% (new buildings) of the building’s energy demand can be covered with renewable energy. The economic evaluation however has shown that under present conditions, none of the investigated supply variants can compete with conventional energy supply (public grid connection + gas condensing boiler).
