International rankings of the competitiveness of economies: low diagnostic and prognostic significance
Harald Lehmann
Wirtschaft im Wandel,
No. 10,
2006
Abstract
Im Rahmen eines Gutachtens für das Bundesfinanzministerium wurde durch das IWH und Prof. Dr. U. Heilemann (Universität Leipzig) untersucht, welchen diagnostischen und prognostischen Aussagegehalt internationale Rankings zur Wettbewerbsfähigkeit von Volkswirtschaften besitzen und welche Bedeutung ihnen damit als Instrument der Politikberatung zukommt. In den vergangenen Jahren sind eine Reihe dieser Länderranglisten veröffentlicht worden, die laufend aktualisiert, aber auch modifiziert werden. Auf der Grundlage umfangreicher Kennzahlensysteme werden hierbei Ranking-Indizes berechnet, die Aussagen über die aktuelle und künftige wirtschaftliche Leistungsfähigkeit der betrachteten Länder liefern sollen. Dies entspringt dem Bedürfnis nach Reduktion hoch dimensionaler, komplexer Zusammenhänge auf einfache Positionsangaben. Angesichts der zunehmenden Beachtung, die solche Berechnungen in der interessierten Öffentlichkeit und Politik erfahren, stellt sich die Frage nach der Bewertung dieser Ergebnisse, zumal sie gerade für Deutschland seit Jahren eine relative Verschlechterung anzeigen. Am Beispiel der drei in Deutschland bekanntesten Rankings – des „Global Competitiveness Report“ des Weltwirtschaftsforums (WEF), Genf, des „World Competitiveness Yearbook“ des International Institute for Management Development (IMD), Lausanne, und des „Internationalen Standort-Ranking 2004“ der Bertelsmann Stiftung, Gütersloh, – zeigt sich, daß solche Rankings in der konkreten Umsetzung aber auch in der Grundkonzeption erhebliche Defizite aufweisen. Sie beruhen allenfalls auf partiell plausiblen wirtschaftstheoretischen Überlegungen, was angesichts der diffusen Theorielage nicht überraschend ist, aber der beanspruchten Wissenschaftlichkeit entgegen steht. Zudem haben „ungeprüfte“ subjektive Einschätzungen – die im Rahmen von Befragungen ermittelt werden – in einigen Rankings großen Einfluß auf die Ergebnisse. Das Vorgehen bei der Kennzahlenaggregation wird nur unzureichend begründet und trägt neben der fehlenden Vergleichbarkeit vieler Angaben zu den Unterschieden in der Bewertung der Länder bei, wenn man die konkurrierenden Ansätze gegenüberstellt. Die größten Einwände aus der Beratungs- bzw. Handlungsperspektive ergeben sich aber aus zwei simplen Befunden der vorliegenden Untersuchung: die nur schwer überzeugend zu rechtfertigende ordinale Bewertung der Länder und die geringe prognostische Leistungsfähigkeit der untersuchten Rankings. Zwar ist ihnen eine gewisse Aufmerksamkeitsfunktion nicht abzusprechen, aus wirtschaftspolitischer Sicht ist ihr diagnostischer und therapeutischer Gehalt aber gering.

Unternehmensbewertung, Rating und Risikobewältigung
Ulrich Blum, Werner Gleißner
Wissenschaftliche Zeitschrift der Technischen Universität Dresden,
2006
Abstract
We inquire into the possibilities to improve the stability of the firms by better managing risk. We propose to directly link risk management to rating, i.e. the ability to meet future financial obligations. Principal elements of rating methodology are discussed against the background of risk management. Next to the rating mark the risk-related requirements for equity become the central measure for risk. Firms must balance the costs of improving their rating against the gains of an improved rating. Risk management is a major driver to improve shareholder value. Risk aggregation is the dominant method that uses information from risk management and synthesizes unique measure of value.

Management von Mitarbeiterrisiken in Unternehmen
Henry Dannenberg
Risikomanagement im Unternehmen Praxisratgeber für die Einführung und Umsetzung, Kapitel 12-7,
2006
Abstract
The paper shows how to quantify the risk of loosing employees. Firstly, reasons will be determined that explain the loss of an employee. Dependent on these reasons, it is shown how to quantify the probability of losing an employee and possible losses that follow an employee loss. Based on these components of risks, a simulation based model is developed which aggregates the risk of all employees of a company to the distribution of the employees risk for the whole company. Finally, a tool for an easy calculating of this risk is presented.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
No. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

Die Bedeutung interner Kapitalmärkte für die Organisationsform von Unternehmen
Diemo Dietrich
WiSt - Wirtschaftswissenschaftliches Studium,
2006
Abstract
Contemporary financial economics has broken new grounds when considering that firms typically have not only a single investment opportunity available conducted by a single manager. A Firm has in fact several projects where headquarters delegates the undertaking to project managers. From this perspective, what conclusions can be drawn regarding the functioning of capital markets? What role do internal capital markets play? What consequences does it have for the borders of a firm?

The Potentials for Technology Transfer via Foreign Direct Investement in Central and East Europe - Results of a Field Study
Judit Hamar, Johannes Stephan
East-West Journal of Economics and Business,
1 & 2
2005
Abstract
Foreign direct investment plays a particularly crucial role for the processes of technological catch-up in Central East Europe. Whilst most countries of this region have received considerable direct investments, the composition of kinds of subsidiaries is different between countries and hence will the prospects for intense technology transfer also differ between countries. This contribution aims to compare the potentials for internal and external technology transfer across countries of Central East Europe by analysing the management-relationship between subsidiaries and their parents and the market-relationships between subsidiaries and their host economy. For this, a firm-level database of some 458 subsidiaries in Estonia, Poland, the Slovak Republic, Hungary, and Slovenia is analysed empirically.

No. 10,
2005
Abstract
At the 7th July 2005, the IWH under the auspices of the department of urban economics hosted a conference on the perspectives of municipal business activity in the range of water supply and disposal. Primary concern of the event was to determine the future role of municipalities. The colloquium was directed towards scientists, practitioners and politicians acting in the range of water management. The contributions addressed a wide range of topics, with the following emphases: benchmarking of municipal economic activity, empirical analyses on the efficiency and the propensity to invest, the problem of spatial disparities within the supply of infrastructure, reform suggestions for the framework of rules of the German water management. The lectures were followed by a panel discussion, attended by representatives from politics, organizations and science.

No. 9,
2005
Abstract
In the public discussion there are controversial argumentations how works worker’s participation in form of work council in questions of office politics and economic interests. Theoretical publications of this topic show mainly positive effects for staff and management. Therefore we analyse the effects of work council for chances in employment. In establishments with a positive result situation at the status quo and a work council we found a positive trend on employment and the future result. Compared to primarily prosperous establishments without staff association downgrade their result situation. In case of negative result situation establishments with a work council have no greater problems to reduce the employment than establishments without a work council.

Non-market Allocation in Transport: A Reassessment of its Justification and the Challenge of Institutional Transition
Ulrich Blum
50 Years of Transport Research: Experiences Gained and Major Challenges Ahead,
2005
Abstract
Economic theory knows two systems of coordination: through public choice or through the market principle. If the market is chosen, then it may either be regulated, or it may be fully competitive (or be in between these two extremes). This paper first inquires into the reasons for regulation, it analyses the reasons for the important role of government in the transportation sector, especially in the procurement of infrastructure. Historical reasons are seen as important reasons for bureaucratic objections to deregulation. Fundamental economic concepts are forwarded that suggest market failure and justify a regulatory environment. The reasons for regulation cited above, however, may be challenged; we forward theoretical concepts from industrial organization theory and from institutional economics which suggest that competition is even possible on the level of infrastructure. The transition from a strongly regulated to a competitive environment poses problems that have given lieu to numerous failures in privatization and deregulation. Structural inertia plays an important role, and the incentive-compatible management of infrastructure is seen as the key element of any liberal transportation policy. It requires that the setting of rules on the meta level satisfies both local and global efficiency ends. We conclude that, in market economies, competition and regulation should not be substitutes but complements. General rules, an "ethic of competition" have to be set that guarantee a level playing field to agents; it is complimented by institutions that provide arbitration in case of misconduct.
