A Novel Approach to Incubator Evaluations: The PROMETHEE Outranking Procedures

IWH Discussion Papers,
No. 1,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that has focused on the outcomes or effectiveness of incubator initiatives and how to measure incubator performance, there is still little understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, this paper applies the multi-criteria outranking technique PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and compares the long-term effectiveness of five technology-oriented BIs in Germany. This is the first time that outranking procedures are used in incubator evaluations. In particular, we investigate whether PROMETHEE is a well-suited methodological approach for the evaluation and comparisons in the specific context of business incubation.

Broadband Investment and the Threat of Regulation: Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
Review of Network Economics,
2007
Abstract
Recently, investments in new generation networks in Germany have been curtailed, since potential investors required this new network be unregulated. To develop a regulator's strategy that allows investments to occur but prevents monopolistic prices, we model an investor's decision problem under a threat of regulation. We show that the mere threat of a regulator's intervention may prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both the investment decision and the investor's price via her signals on regulation probability and price.

Risikomanagement als Werttreiber: volks- und betriebswirtschaftliche Perspektive
Ulrich Blum, Werner Gleißner
Wertorientiertes Management,
2005
Abstract
Worin unterscheiden sich erfolgreiche von weniger erfolgreichen "Bewältigern des Risikos", und welche Techniken sind verfügbar, die den Umgang mit Risiko erleichtern. Zunächst wird der Frage nachgegangen, was sich institutionell geändert hat, weshalb (ökonomische) Risiken möglicherweise stärker als zu früheren Zeiten auf das Individuum bzw. das Unternehmen (insbesondere das KMU) durchschlagen. Die Antwort findet sich vor allem in Prozessen, die mit den Begriffen "Globalisierung" und "Netzwerkökonomie" verbunden sind. Sodann werden ökonomische Aspekte des Risikos vertieft, dabei auch der Frage nachgegangen, wodurch eigentlich Wohlstand entsteht, um schließlich zu prüfen, welche Wirkungsbeziehungen in Richtung auf den Unternehmenswert bestehen. Dabei wird zwischen vollkommenen und unvollkommenen Märkten unterschieden. Darauf aufbauend wird schließlich eine Systematik des Risikomanagements vorgestellt und daran aufgezeigt, wie dieser "Wertreiber" zur Unternehmensentwicklung beitragen kann. Darauf baut eine Darstellung der Organisation des Risikomanagements im Unternehmen auf. Ein Ausblick zeigt auf, wie volkswirtschaftliche Institutionen weiterentwickelt werden können, um die Risikoallokation zu optimieren.

Outperforming IMF Forecasts by the Use of Leading Indicators
Katja Drechsel, Sebastian Giesen, Axel Lindner
IWH Discussion Papers,
No. 4,
2014
Abstract
This study analyzes the performance of the IMF World Economic Outlook forecasts for world output and the aggregates of both the advanced economies and the emerging and developing economies. With a focus on the forecast for the current and the next year, we examine whether IMF forecasts can be improved by using leading indicators with monthly updates. Using a real-time dataset for GDP and for the indicators we find that some simple single-indicator forecasts on the basis of data that are available at higher frequency can significantly outperform the IMF forecasts if the publication of the Outlook is only a few months old.

Africa and the Global Financial Crisis - Impact on Economic Reform Processes
R. Adelou Alabi, J. Alemazung, Achim Gutowski, Robert Kappel, Tobias Knedlik, O. Osnachi Uzor, Karl Wohlmuth, Hans H. Bass
African Development Perspectives Yearbook, Vol. 15,
2011
Abstract
In volume XV of the African Development Perspectives Yearbook, the Research Group on African Development Perspectives investigates the impact of the GFC on economic reform processes in Africa. The analysis is structured in such a way so as to reflect the opportunities and dangers of policy reversals in the face of the GFC. The impact of the crisis on different types and forms of governance in the region is considered. The first question is therefore which macro-economic policy instruments have to be applied in order to overcome the crisis and to continue with sustainable development. The second question is how the GFC has affected Africa's external economic relations and if the path of opening up to the world markets is continued. The third question raised is how the crisis has affected social cohesion, impacted on poverty alleviation strategies and the achievement of Millennium Development Goals (MDGs). All these questions are discussed in the various contributions which comprise general studies and country case studies. The authors also looked into the role of international financial institutions during and after the crisis. The volume XV of the African Development Perspectives Yearbook is structured into three Units. Unit 1 addresses general issues regarding the impact of the GFC on reform processes in Africa. Unit 2 presents case studies from countries and sub-regions. Unit 3 presents reviews and book notes of current literature focusing on issues of African development perspectives.
