The KLU faculty, post-docs, and PhD candidates regularly publish the results of their research in scientific journals. You will find a complete overview of all KLU publications below (e.g. articles in peer-reviewed journals, professional journals, books, working papers, and conference proceedings). Search for relevant terms and keywords, or filter the list by name, year of publication or type of publication. The references include DOIs and abstracts where available, and you can download them to your own reference database or platform. We regularly update the database with new publications.

Abstract: I developed a simplified version of a decision support system for Health Net. Health Net needed a system to manage fixed-income portfolios worth $370 million and to analyze 36 different types of fixed-income securities and derivatives for risk and return. I integrated the required mathematical models and database system in the object-oriented paradigm by uniformly implementing mathematical models for interest rate movements and cash flows of securities, database entities, and the interface as interacting objects.

Abstract: Using 1989–1992 individual data of 757 German cooperative banks and applying the intermediation approach we specify a multi-product translog cost function for this part of the German banking industry. For all size classes moderate economies of scale can be identified. There is also evidence of economies of scope which supports the notion of universal banking. As for cost efficiency, we find that the average banks in all size classes deviate considerably from the best practice cost frontier. All banks enjoy growth of total factor productivity, which is higher for the smaller banks in the sample.

Abstract: Im Mittelpunkt dieser Studie steht die Fragestellung, in welchem Ausmaß Gewinnunterschiede und Marktanteilsveränderungen auf Effizienzunterschiede zwischen den Unternehmen zurückzuführen sind. Hierzu wird in einem ersten Schritt mit Hilfe des Fixed-Effects- sowie des Stochastic-Frontier-Ansatzes die unternehmensspezifische Kosteneffizienz bestimmt. In einem zweiten Schritt wird dann der Zusammenhang zwischen Kosteneffizienz einerseits und den Marktergebnisvariablen Profitabilität sowie Marktanteilsveränderung andererseits untersucht. Dieser Zusammenhang ist um so enger, je wettbewerblicher das Unternhemnsverhalten ist. Für den deutschen Bankensektor, repräsentiert durch Paneldaten von 1425 deutschen Universalbanken, deuten die Berechnungen auf sigifikante Unterschiede zwischen den Bankengruppen hin. Während die Gewinne von Genossenschaftsinstituten relativ stark von der Kosteneffizienz beeinflußt werden, ist dies bei Sparkassen sowie Kreditbanken kaum der Fall. Untersucht man dagegen die Beziehung zwischen Marktanteilsentwicklung und Effizienz, dann ist der Erklärungsgehalt für den Sparkassensektor größer als für die beiden anderen Bankengruppen.

Abstract: How can operations research/management science (OR/MS) professionals take advantage of the Internet, a global network of computers? One avenue is communication forums—e-mail list servers and Usenet news groups—for networking with professionals from OR/MS and other areas. The second avenue is accessing and creating repositories that archive information, such as software, technical papers, and conference programs. Online lists cover both repositories and forums. Tools allow users to access these repositories and to share information with research collaborators around the world. The Internet can be useful, but users should not expect too much.

Abstract: Der optimale Entlohnungsplan fuer Verkaufsaussendienstmitarbeiter laesst sich im Rahmen typischer Prinzipal-Agenten-Modelle bestimmen.Empirische Untersuchungen haben jedoch gezeigt, dass die Ergebnisse der theoretischen Analyse nicht mit den in der Praxis zu beobachtenden Entlohungsplaenen uebereinstimmen.
