Abstract
Powszechnie wykorzystywane do pomiaru ryzyka miary, jakimi są odchylenie standardowe oraz Value-at-risk nie zawsze oddają charakter mierzonego ryzyka. Dla uogólnienia problematyki pomiaru ryzyka zaproponowano podejście związane z koherentnymi miarami ryzyka. W pracy omówiono aksjomatykę związaną z proponowanym podejściem oraz przegląd miar związanych z omawianą aksjomatyką. Przedstawiono również dyskusję omawianych wasności oraz możliwości praktycznych zastosowań.

The widely used risk measures as standard deviations and value at risk do not always reflect risk preferences accurately. To overcome this problem we show coherent risk approach. For making the overview of the problem of risk measure we propose a coherent risk measure approach. We started from the definition of risk (market and other) and we took a close look at construction of risk measures. We present a set of axioms according to this approach and a collection of coherent risk measures. In particular, we describe quantile risk measures, distortion risk measures with detailed presentation of the most frequent distortion functions in use. The next propositions are risk measures based on lower partial moments. We show some properties of these measures and also discuss limitations of such measures in practical applications.
