In past years the study of the impact of risk attitude among risks has become a major topic, in particular in Decision Sciences. Subsequently the attention was devoted to the more general case of bivariate random variables. The first approach to multivariate risk aversion was proposed by de...

In this note we consider a multicriteria decision problem where the decision maker know the the state of the world but the set of consequences is multidimensional. We suppose that a value function is specified over the attribute of the decision problem and we analyze some classes of non additive...

In this paper non-monotonic measures and their properties are considered and described. Subsequently we study discrete non-monotonic Choquet integral under the viewpoint of aggregation, and its axiomatic characterization. Moreover, we show that for non-monotonic measures the Shapley index can...

The properties of risk measures or insurance premium principles have been extensively studied in actuarial literature. We propose an axiomatic description of a particular class of coherent risk measures defined in Artzner, Delbaen, Eber, and Heath (1999). The considered risk measures are...

In the de Finetti-Arrow-Pratt framework, the utility for wealth is assumed to be not changing with time, i.e. utility is timeless. Given that clearly preferences may change with time, in the context of time varying utility of wealth, this paper defines temporal risk aversion in the case of a...

Purpose – The objective of this paper is to highlight the results of a survey on compliance practices in Italian financial institutions (Italian banks and branches in Italy of foreign banks). Design/methodology/approach – The survey is carried out through a structured questionnaire, arranged...

In this paper we consider the problem of determining approximations for distortion risk measures of sums of non-independent random variables. First, we give an overview of the recent actuarial literature on distortion risk measures and convex bounds for sums of random variables. Then, we examine...

Purpose – The authors' paper aims to examine the organizational issues that come from the recent establishment of the compliance function in Italian banks. Design/methodology/approach – The authors' paper takes as a starting point the Bank of Italy's regulations and the existing literature...
