In this paper, we propose simulation based Bayesian inference procedures in a cost system that includes the cost function and the cost share equations augmented to accommodate technical and allocative inefficiency. Markov Chain Monte Carlo techniques are proposed and implemented for Bayesian...

Seit der Einführung der unter Basel II bekannten bankaufsichtlichen Anforderungen ist der Druck auf Kreditinstitute, verfeinerte Risikomessmethoden zu entwickeln, deutlich angestiegen. Besonders bemerkbar macht sich das bei der Messung und Steuerung von Kreditrisiken. Maria Stefanova untersucht...

The stochastic frontier analysis (Aigner et al., 1977, Meeusen and van de Broeck, 1977) is widely used to estimate individual efficiency scores. The basic idea lies in the introduction of an additive error term consisting of a noise and an inefficiency term. Most often the assumption of a...

In this paper we stress-test credit portfolios of 28 German banks based on a Mertontype multi-factor credit risk model. The ad-hoc stress scenario is an economic downturn in the automobile industry that constitutes an exceptional but plausible event suggested by historical data. Rather than on a...

This article provides an empirical insight on the heterogeneity in the estimates of banking efficiency produced by the stochastic frontier approach. Using data from five countries of Central and Eastern Europe, we study the sensitivity of the efficiency score and the efficiency ranking to a...

Die vorliegende Studie wurde im ifo Arbeitsbereich Branchenforschung erstellt und im Frühjahr 2005 abgeschlossen. Auftraggeber war das Bundesministerium für Wirtschaft und Arbeit. Gegenstand der Studie sind der Stand und die Perspektiven der „New Economy“ in Deutschland sowie ein Vergleich...
