Under Solvency II the computation of capital requirements is based on value at risk (V@R). V@R is a quantile-based risk measure and neglects extreme risks in the tail. V@R belongs to the family of distortion risk measures. A serious deficiency of V@R is that firms can hide their total downside risk in corporate groups. They can largely reduce their total capital requirements via appropriate tra...

in recent decade, several methodologies and tools have been developed to undertake a risk analysis in order to prevent accidents in the process industries. attempts have been made to study and compare these methods. however, yet no method has been proposed to aid managers in a scientific selection of a proper risk analysis method. in this paper, we have presented a multi criteria decision makin...

risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. the conventional approaches tend to be less effective in dealing with the impreciseness of risk response pl...

Recently, Support Vector Regression (SVR) has been introduced to solve regression and prediction problems. In this paper, we apply SVR to financial prediction tasks. In particular, the financial data are usually noisy and the associated risk is time-varying. Therefore, our SVR model is an extension of the standard SVR which incorporates margins adaptation. By varying the margins of the SVR, we ...

Most of the existing multiple criteria decision-making methods handle one kind of the information imperfections at the same time. Stochastic methods and fuzzy methods constitute typical examples of these methods. However, several multiple criteria modelizations include simultaneously many kinds of the information imperfections. In this work, we propose a multiple criteria aggregation procedure ...

Grund für dieses Urteil war die fehlende Umsetzung des Prinzips der Öffentlichkeit der Wahl.

This paper studies the relationship between multinationality and performance under a real options lens. Based on a cross-sectional panel of multinational corporations (MNCs) that are likely to use real options reasoning for the management of their operations, we test the impact of operating and strategic options on firms’ risk-returns parameters. Our evidence reveals that both multinationality ...
