This paper develops a novel methodology to study robust stability properties of Nash equilibrium points in dynamic games. Small-gain techniques in modern mathematical control theory are used for the first time to derive conditions guaranteeing uniqueness and global asymptotic stability of Nash...

In this paper we first recall the concept of w-distance on a metric space. Then, we prove a fixed point theorem for singlevalued operators in terms of a w-distance.

This report shows how to determine in analytic form the security prices implied by the market equilibrium model described by Fama in his book "Foundations of Finance", Chapter 8, Section III. The model assumes that all investors agree on the expected values and covariances of the random final...

Most executives know that overarching paints of plausible futures will profoundly affect the competitiveness and survival of their organisation. Initially from the perspective of Shell, this article discuses oil scenarios and their relevance for upstream investments. Scenarios are then...

It is shown that in the case of a single decision maker who optimizes several possibly conflicting objectives, the amount of information available in preference relations among pairs of possible decisions, when compared with all other possible information, is tending to zero exponentially with...

This document presents several Credit Risk tools which have been developed for the Credit Derivatives Risk Management. The models used in this context are suitable for the pricing, sensitivity/scenario analysis and the derivation of risk measures for plain vanilla credit default swaps (CDS),...

This study has two main contributions summarized as follows: 1. Impact of ICT on the capacities of innovation: The most intensive firms in ICT are also those that tend more frequently to innovate and to combine several innovations types - i.e. they are also “intensive innovator”. However,...

Elements of eventologic axiomatics are offered. Eventology [Vorobyev, 2007], a new direction of probability theory and philosophy, offers the original many-event-based approach to the description of many-agent being and co-being, entering human agents, together with his/her beliefs, directly in...

The present article deals with the theme of efficiency in healthcare and especially technical efficiency in psyaciatric hospital care. We used the method of data envelopment analysis (DEA), which finds increasing application in many spheres of public life, including healthcare. We subdivided the...
