The purpose of this study was to examine interrelationship and causal linkages between socioeconomic and environmental variables in OECD countries. To aid this study, a LISREL modelling tool was implemented. The findings of the study indicated that gross public debt increases with deterioration...

The present project is related in the measurement of the risk and the improvement of the processes of monetary species. The main objective is to offer a methodology in the tickets administration because understanding of history is a situation that becomes in an advantage on the opportunities at...

Business and risk have always been considered complementary concepts. Many companies are successful because of their ability to correctly recognize and to direct successfully all the risks resulting from the activities developed. Thus, we may say without being wrong, that risk represents an...

Scenario Analysis (SA) plays a key role in determination of operational risk capital under Basel II Advanced Measurement Approach. However, operational risk capital based on scenario data may exhibit high sensitivity or wrong-way sensitivity to scenario inputs. In this paper, we first discuss...

The aim of this paper is to simulate profit expectations as an emergent property using an agent based model. The paper builds upon adaptive expectations, interactive expectations and small world networks, combining them into a single adaptive interactive profit expectations model (AIE)....

The class of defensive online portfolio selection algorithms,designed for fi nite investment horizon, is introduced. The Game Constantly Rebalanced Portfolio and the Worst Case Game Constantly Rebalanced Portfolio, are presented and theoretically analyzed. The analysis exploits the rich set of...

The general aim of this article is to present genetic algorithms as a tool, that can be used in de-mand forecasting in internet shops. First part of article identities factors, which have to be taken into consideration during analysing demand in internet shops, e.g. dispersion of demand,...

The optimal stopping problem for the risk process with interests rates and when claims are covered immediately is considered. An insurance company receives premiums and pays out claims which have occured according to a renewal process and which have been recognized by them. The capital of the...

We analyze investments in gas-fired power plants under stochastic electricity and natural gas prices. A simple but realistic two-factor model is used for price processes, enabling analysis of the value of operating flexibility, the opportunity to abandon the capital equipment, as well as finding...

We give short proofs of general theorems about optimal entry and exit problems in Levy models, when payoff streams may have discontinuities and be non-monotone. As applications, we consider exit and entry problems in the theory of real options, and an entry problem with an embedded option to exit.
