Reliable information on small- and medium-sized enterprises (SMEs) is rare and costly for financial intermediaries. Therefore relationship banking is often considered as the appropriate lending technique. In this paper we offer a theoretical model to analyze relationship banking and the pricing behavior of banks in a Bertrand competition framework with monitoring costs. We show that the lack of reliable information leads to comparable high interest rates even if a long-term relationship between borrower and bank exists. The paper offers a theoretical explanation why SMEs often are faced with borrowing constraints.

A casual look at regional unemployment rates reveals that there are vast differences, which cannot be explained by different institutional settings. Our paper attempts to trace these differences in the labor market performance back to the regions' specialization in products that are more or less advanced in their product cycle. The model we develop shows how individual profit and utility maximization endogenously yields higher employment levels in the beginning. In later phases, however, employment decreases in the presence of process innovation. Our model suggests that the only way to escape from this vicious circle is to specialize in products that are at the beginning of their "economic life". The model is based on an interaction of demand and supply side forces.
Die Anwendung eines Mikrosimulationsmodells als Instrument der wirtschaftswissenschaftlichen Forschung erfreut sich großer Beliebtheit. Die Verwendung dieses Modelltyps hat vor allem zwei Gründe. Zum einen sind die in den letzten Jahren extrem gesunkenen Kosten der Informationsverarbeitung ursächlich für die mittlerweile häufige Verwendung. Zum anderen besitzt diese Analyseform Eigenschaften, die kein anderes Instrument aufweist. Insbesondere für die Abschätzung der Verteilungswirkungen von Steuer- und Transferreformen ist die Mikrosimulation eine nahezu ideale Methode. Durch die Einbindung eines Nachfragesystems kann sowohl das Anwendungsgebiet eines Mikrosimulationsmodells erweitert als auch dessen potentielle Leistungsfähigkeit gesteigert werden. Die Arbeit hat im Wesentlichen die Beantwortung der Fragestellungen aus den folgenden zwei Fragenkomplexen zum Ziel: - Wann ist die Einbindung eines Nachfragesystems in Mikrosimulationsmodelle sinnvoll und wie kann ein solches System in das eigentliche Mikrosimulationsmodell integriert werden? - Welche Nachfragesysteme können aus den in Deutschland in Querschnittsform vorhandenen Mikrodatensätzen geschätzt werden und welche theoretischen Eigenschaften besitzen diese Systeme bzw. deren in einem zweistufigen Budgetierungsprozess einsetzbare Kombinationen?
China, as being the largest foreign direct investment (FDI) host country in the world and the leading developing country in terms of volume of FDI inflows, has been increasingly attracting international attention from companies and policy makers. As more and more German manufacturing companies move into China, the investment is becoming larger in size and of higher quality. In the meantime, issues of the motives and nature of German FDI in China and related technological activities are developed to a more important topic for both Chinese and overseas researchers. This paper aims at the analysis and explanation of FDI movement driven by German companies in China and the role of technology hereby. Our research includes a literature review, a database analysis and a mail survey on German firms investing in China. Different indicators suggest that the motives for German FDI are long-term based and are deeply market-oriented, which can be characterised through seeking new markets and enlarging market shares. Technology transfer is therefore mainly dedicated to production and managerial facilities.
