A revised theory of contestable markets : applied on the German telecommunication sector
Christian Growitsch, Thomas Wein
Externe Publikationen,
No. 275,
2002
Abstract
Despite the scepticism raised by the German Monopoly Commission our analysis shows that the revised theory of contestable markets can be applied to the telecommunications market better than expected. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit is possible without any costs, and the price adjustment lag exceeds the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions are satisfied for potential competition to exist. We applied the ‘revised’ contestable market theory to the German telecommunication market and have been able to clearly identify the value added stages in which regulation is required. Under the present conditions local loops - which can be determined as natural monopolies - are not contestable due to sunk costs, high entry lags expected and a probable short price adjustment lag. Local loops can be identified as monopolistic bottlenecks therefore. Regional and local connection networks should also be regulated because a high entry lag and a low price adjustment lag have to be expected as well as current competition does not exist today. The national connection network shows current competition between several network providers; hence regulation can be abolished in this field. Assumed that network access is regulated, services can be supplied by several competing firms.

The significance of FDI for innovation activities within domestic firms - The case of Central East European transition economies

2002
Abstract
Ausländischen Direktinvestitionen wird in den mittelosteuropäischen Ländern eine wesentliche Rolle als Multiplikator modernen Produktions- und Management-Knowhows zugeschrieben. Die sogenannten Technologie-Spillovers werden in der Theorie auf Externalitäten bzw. Extra-market-linkages erklärt. In der Praxis kommen sie über Demonstrationseffekte, Arbeitskräftemobilität, Zuliefererkontakte, Kundenkontakte oder Netzwerkaktivitäten zustande. Die empirische Untersuchung am Beispiel der ungarischen Industrie zeigt jedoch, dass ausländische und einheimische Unternehmen vor allem aufgrund der hohen technologischen Entwicklungsunterschiede weitgehend getrennte Sphären innerhalb des Industriesektors bilden. Daher kommen Technologie- Spillover als innovationsförderndes Instrument einheimischer Unternehmen kaum zustande.

Bank-Firm Relationships and International Banking Markets
Hans Degryse, Steven Ongena
International Journal of the Economics of Business,
No. 3,
2002
Abstract
This paper reviews how long-term relationships between firms and banks shape the structure and integration of banking markets worldwide. Bank relationships arise to span informational asymmetries that are endemic in financial markets. Firm-bank relationships not only entail specific benefits and costs for both the engaged firms and banks, but also directly affect the structure of banking markets. In particular, the sunk cost of screening and monitoring activities and the 'informational capital' collected by the incumbent banks may act as a barrier to entry. The intensity of the existing firm-bank relationships will determine the height of this barrier and shape the structure of international banking markets. For example, in Scandinavia where firms maintain few and strong relationships, foreign banks may only be able to enter successfully through mergers and acquisitions. On the other hand, Southern European firms maintain many bank relationships. Therefore, banks may consider entering Southern European banking markets through direct investment.

Wage indemnity rule is no sufficient criterion for positive work incentives in low-wage sector
Hilmar Schneider, Wolfram Kempe
Wirtschaft im Wandel,
No. 4,
2002
Abstract
Mit einem mikroökonomischen Arbeitsangebotsmodell wird gezeigt, dass das Lohnabstandsangebot zwischen Sozialhilfe und Erwerbseinkommen zwar ein notwendiges Kriterium ist, um einen positiven Anreiz zur Erwerbsaufnahme potentieller Niedriglohnbezieher auszuüben, jedoch kein hinreichendes. Der Abstand Ende 2001 wird für einige Branchen ermittelt. Der Umstand, dass dieser Abstand in einigen Fällen sogar negativ ist, wirkt um so schwerwiegender, als das erzielbare Erwerbseinkommen relativ deutlich über dem Lohnersatzeinkommen in Form der Sozialhilfe liegen müsste. Eine Beschäftigung lohnt sich in finanzieller Hinsicht am ehesten für alleinlebende Sozialhilfeempfänger, während für Familien mit mehreren Kindern nicht einmal das notwendige Kriterium des positiven Lohnabstandes immer erfüllt ist.

Macroeconomic Modelling of the German Economy in the Framework of Euroland
Rüdiger Pohl, Heinz P. Galler
Schriften des IWH,
No. 11,
2002
Abstract
An attempt to develop a new macroeconometric model for Germany is confronted with several questions that range from the general rationality of such an approach to specific problems of an appropriate model structure. One important aspect of this discussion is the introduction of the Euro as a common currency of the European monetary union. This institutional change may result in structural breaks due to changing behavior of economic agents. In addition, the definition of the spatial unit that is appropriate for modelling becomes a problem. Additional problems come from the introduction of the European Single Market and the increasing international economic integration not only within the European union but also beyond its borders. And in the case of Germany, the unification of the West and the East demand special attention. Last but not least, the harmonization of national accounting for the member states of the European Union has to be dealt with. Thus, the introduction of the Euro as a common currency is just one problem besides others that must be addressed.

Are the Central and Eastern European Transition Countries still vullnerable to an Financial Crisis? Results from the Signals Approach
Axel Brüggemann, Thomas Linne
IWH Discussion Papers,
No. 157,
2002
Abstract
The aim of the paper is to analyse the vulnerability of the Central and Eastern European accession countries to the EU as well as that of Turkey and Russia to a financial crisis. Our methodology is an extension of the signals approach. We develop a composite indicator to measure the evolution of the risk potential in each country. Our findings show that crises in Central and Eastern Europe are caused by much the usual suspects as in others emerging markets. In particular an overvalued exchange rate, weak exports and dwindling currency reserves have good predictive power for assessing crisis vulnerabilities.

Bank Concentration and Retail Interest Rates
S. Corvoisier, Reint E. Gropp
Journal of Banking and Finance,
No. 11,
2002
Abstract
The recent wave of mergers in the euro area raises the question whether the increase in concentration has offset the increase in competition in European banking through deregulation. We test this question by estimating a simple Cournot model of bank pricing. We construct country and product specific measures of bank concentration and find that for loans and demand deposits increasing concentration may have resulted in less competitive pricing by banks, whereas for savings and time deposits, the model is rejected, suggesting increases in contestability and/or efficiency in these markets. Finally, the paper discusses some implications for tests of the effect of concentration on monetary policy transmission.
