Związki miar awersji do ryzyka z funkcjami zależnymi od parametrów rozkładu

The expected utility model (EU) and the mean-variance model (M-V) are the most common approaches to analyzing choices under uncertainty. These two models produce the preference relations which are only consistent under additional restrictions. Although the mean-variance preferences has been important in financial economics, such a concept of risk is not consistent with others. However, the decision makers select alternatives by comparing their risk, and various risk measures are employed. The main aim of the paper is to compare various concepts of measure of risk aversion and present some conditions providing consistency in the two approaches.
