The design and analysis of efficient approximation schemes is of fundamental importance in stochastic programming research. Bounding approximations are particularly popular for providing strict error bounds that can be made small by using partitioning techniques. In this article we develop a powerful bounding method for linear multistage stochastic programs with a generalized...

We examine how bank funding and securitization activity affect the currency denomination of business loans. We analyze a unique dataset that for more than hundred thousand loans granted by one Bulgarian bank to over sixty thousand different firms in the period 2003-2007 includes information on the requested and granted currency of the loans. Our findings confirm the conjecture that...

This paper investigates, how the 2007-08 financial crisis has affected the risk perceptions of institutional bond investors. Using a methodology novel to the empirical finance literature, we quantify the impact that changes in risk perception have had on bond spreads over the course of the crisis. The relative contribution of the change in risk perceptions can be measured by...

In this paper, we investigate the relation between firm-level corporate governance and firm value based on a large and previously unused dataset from Governance Metrics International (GMI) comprising 6,663 firm-year observations from 22 developed countries over the period from 2003 to 2007. Based on a set of 64 individual governance attributes we construct two alternative additive...

High Responsibility Teams (HRTs) tragen mit ihrem Handeln und dessen Konsequenzen eine hohe Verantwortung für das Leben und die Gesundheit von Menschen und für den Schutz der Umwelt. Ungeachtet dessen existieren für viele dieser HRTs, wie z.B. in der Polizei, der Feuerwehr oder der Anästhesie, keine wissenschaftlich fundierten Konzepte für eine nicht-technische Kompetenzentwicklung...

In dieser Sonderausgabe berichten wir Ihnen von unserer neusten Errungenschaft SteelSim.
Seit April diesen Jahres produzieren wir in unseren Laborräumen in einem Hochofen 1400° heisses Roheisen. Selbstverständlich nur im Modell.
Wie bereits in vorangegangenen Ausgaben erwähnt und angekündigt, wurde im April (endlich) unser neues Forschungs-werkzeug, der Simulator SteelSim...
