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.

Knowledge Sharing Through Informal Networking: An Overview and Agenda
Michael Schwartz, Christoph Hornych
International Journal of Knowledge-Based Development,
Nr. 3,
2011
Abstract
Informal inter-organizational networks provide manifold opportunities to organize the transfer of information, knowledge and technology between actors. The importance of informal networks as a channel of knowledge transfer is widely acknowledged by academics and practitioners. However, there is a significant lack of discussion on their theoretical foundations and systematic empirical research on the origins, dynamics and effects of informal networking. The objective of this paper is threefold. First, we review the fragmented academic discussion of the notion of informal networking, thereby focusing on how these relationships emerge initially and what conditions (presumably) are required to make them a mutually fruitful and sustainable channel of the transfer of information and knowledge. Second, we give an up-to-date overview over most important and recent studies trying to disentangle the mechanisms of inter-organizational informal networking. Finally, we outline an agenda of future research directions which we encourage researchers to pursue in future empirical studies. Overall, six important research gaps are identified.

Identifying Industrial Clusters from a Multidimensional Perspective: Methodical Aspects with an Application to Germany
Matthias Brachert, Mirko Titze, Alexander Kubis
Papers in Regional Science,
Nr. 2,
2011
Abstract
If regional development agencies assume the cluster concept to be an adequate framework to promote regional growth and competitiveness, it is necessary to identify industrial clusters in a comprehensive manner. Previous studies used a diversity of methods to identify the predominant concentrations of economic activity in one industrial sector in a region. This paper is based on a multidimensional approach developed by Titze et al. With the help of the combination of concentration measures and input–output methods they were able to identify horizontal and vertical dimensions of industrial clusters. This paper aims to refine this approach by using a superior measure of spatial concentration and by integrating information about spatial interdependence of industrial cluster structures to contribute to a more adequate framework for industrial cluster identification.

Abstract
deutscher Titel: Makroökonomische Herausforderungen für die Eurozone und die Beitrittskandidaten
Abstract: The conduct of effective economic policy faces a multiplicity of macroeconomic challenges, which requires a wide scope of theoretical and empirical analyses. With a focus on the European Union, this doctoral dissertation consists of two parts which make empirical and methodological contributions to the literature on forecasting real economic activity and on the analysis of business cycles in a boom-bust framework in the light of the EMU enlargement. In the first part, we tackle the problem of publication lags and analyse the role of the information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A huge dataset of monthly indicators is used to estimate simple bridge equations. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We find that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. In the second part, we focus on the potential accession of the new EU Member States in Central and Eastern Europe to the euro area. In contrast to the discussion of Optimum Currency Areas, we follow a non-standard approach for the discussion on abandonment of national currencies the boom-bust theory. We analyse whether evidence for boom-bust cycles is given and draw conclusions whether these countries should join the EMU in the near future. Using a broad range of data sets and empirical methods we document credit market imperfections, comprising asymmetric financing opportunities across sectors, excess foreign currency liabilities and contract enforceability problems both at macro and micro level. Furthermore, we depart from the standard analysis of comovements of business cycles among countries and rather consider long-run and short-run comovements across sectors. While the results differ across countries, we find evidence for credit market imperfections in Central and Eastern Europe and different sectoral reactions to shocks. This gives favour for the assessment of the potential euro accession using this supplementary, non-standard approach.

Vermögenspreisblasen: Erklärungsansätze und wirtschaftspolitische Überlegungen
Oliver Holtemöller
Wirtschaft im Wandel,
Nr. 12,
2010
Abstract
Auf Vermögensmärkten ist es in der Wirtschaftsgeschichte immer wieder zu Preisblasen gekommen, also Situationen, in denen auf eine Phase stark steigender Preise ein abrupter Preissturz folgt. Wie lässt sich dieses Phänomen erklären? In diesem Beitrag wird erörtert, wie sich in einer Gesellschaft die Vorstellung durchsetzen kann, dass hohe zukünftige Gewinne stark steigende Vermögenspreise rechtfertigen. Meist basiert diese Vorstellung auf einer plausiblen Geschichte, die an aktuellen Gegebenheiten anknüpft. Während der Internetblase um die Jahrtausendwende wurde zum Beispiel davon
ausgegangen, dass neue Kommunikations- und Informationstechnologien dauerhaft ein höheres Wirtschaftswachstum als zuvor ermöglichen würden.
Zur Verbreitung einer solchen Geschichte tragen auch psychologische Phänomene wie Konformität und übermäßiges Selbstvertrauen bei. Diese Phänomene können erklären, warum viele Investoren bereit sind, Vermögensgüter zu Preisen
zu kaufen, die dann im Nachhinein ungerechtfertigt hoch erscheinen. Diese psychologischen Phänomene lassen sich nicht ohne Weiteres durch wirtschaftspolitische Maßnahmen ausschalten – zumal auch die wirtschaftspolitischen Entscheidungsträger von ihnen betroffen sein dürften. Weil die Ursachen für Vermögenspreisblasen somit schwer zu bekämpfen sind, sollte die Wirtschaft Rahmenbedingungen haben, die Häufigkeit, Ausmaß und
negative Folgen dieser Blasen zu reduzieren helfen. Dazu zählen insbesondere Regulierungs- und Überwachungsmechanismen für diejenigen Akteure, die den Kauf von Vermögensgütern mit Fremdkapital finanzieren.

Analyzing Innovation Drivers in the German Laser Industry: the Role of Positioning in the Social and Geographical Space
Muhamed Kudic, Peter Bönisch, Iciar Dominguez Lacasa
Abstract
Empirical and theoretical contributions provide strong evidence that firm-level performance outcomes in terms of innovativeness can either be determined by the firm’s position in the social space (network effects) or by the firm’s position in the geographical space (co-location effects). Even though we can observe quite recently first attempts in bringing together these traditionally distinct research streams (Whittington et al. 2009), research on interdependent network and geographical co-location effects is still rare. Consequently, we seek to answer the following research question: considering that the effects of social and geographic proximity on firm’s innovativeness can be interdependent, what are the distinct and combined effects of firm’s network and geographic position on firm-level innovation output? We analyze the innovative performance of German laser source manufacturers between 1995 and 2007. We use an official database on publicly funded R&D collaboration projects in order to construct yearly networks and analyze firm’s network positions. Based on information on population entries and exits we calculate various types of geographical proximity measures between private sector and public research organizations (PRO). We use patent grants as dependent variable in order to measure firm-level innovation output. Empirical results provide evidence for distinct effect of network degree centrality. Distinct effect of firm’s geographical co-location to laser-related public research organization promotes patenting activity. Results on combined network and co-location effects confirms partially the existence of in-terdependent proximity effects, even though a closer look at these effects reveals some ambiguous but quite interesting findings.

Informal Networking - An Overview of the Literature and an Agenda for Future Research
Michael Schwartz, Christoph Hornych
Abstract
Informelle Netzwerkstrukturen bieten vielfältige Möglichkeiten, den Transfer von Informationen, Wissen und Technologie zwischen Akteuren zu organisieren. In Anbetracht des Potentials sowie der Bedeutung informeller Netzwerke ist der bestehende Mangel an theoretischen Diskussionen wie auch empirischer Forschung überraschend. Hier setzt der Beitrag an, indem eine Bündelung der bislang lediglich in Fragmenten vorliegenden Auseinandersetzung mit dem Konzept informeller Netzwerke vorgenommen wird. Der Fokus wird dabei auf Fragen der Entstehung solcher Netzwerkstrukturen sowie auf diejenigen Faktoren gelegt, die notwendig sind, informelle Netzwerke als effektiven und beständigen Kanal des Wissens- und Technologietransfers nutzbar zu machen. In einem zweiten Teil des Beitrags wird ein Überblick über die wichtigsten, zum gegenwärtigen Zeitpunkt existierenden, Studien gegeben, die sich empirisch mit dem Konzept informeller Netzwerkstrukturen auseinandersetzen. Basierend auf dieser Aufarbeitung werden anschließend fünf wichtige Forschungsfragen formuliert, die im Fokus zukünftiger Forschungsbestrebungen stehen sollten.

Currency Crisis Prediction Using ADR Market Data: An Options-based Approach
Stefan Eichler, Dominik Maltritz
International Journal of Forecasting,
Nr. 4,
2010
Abstract
During capital control episodes, large price deviations between American Depositary Receipts (ADR) and their underlying stocks signal that a currency crisis is about to occur. We interpret this price spread as the price of a call option. Using option pricing theory we derive detailed information about both the probability of a currency crisis and the expected magnitude of devaluation. Analyzing daily ADR market data preceding the Venezuelan crisis (1996), our approach predicts crisis probabilities of almost 100% and forecasts the exchange rate after floating quite accurately. During the Argentine crisis (2002), the estimated exchange rates are similar to the actual ones.
