In this paper we consider the problem of studying the gap between bounds of risk measures for sums of non-independent random variables. Owing to the choice of the context where to set the problem, namely that of distortion risk measures, we first deduce an explicit formula for the risk measure...

In this paper we focused our attention to the study of an excess of loss reinsurance with reinstatements, a problem previously studied by Sundt [5] and, more recently, by Mata [4] and HÄurlimann [3]. As it is well-known, the evaluation of pure premiums requires the knowledge of the claim size...

This paper studies excess of loss reinsurance with reinstatements in the case in which the aggregate claims are generated by a discrete distribution, in the framework of risk adjusted premium principle. By regarding to comonotonic exchangeability, a generalized definition of initial premium is...

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...

Recently in actuarial literature several authors have derived lower and upper bounds in the sense of convex order for sums of random variables with given marginal distributions and unknown dependency structure. In this paper, we derive convex bounds for sums of non-independent and identically...

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...

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...

The main goal of this research is to analyze Italian tourists' behaviors on the basis of statistical surveys on households, life conditions, incomes, consumptions, travels and vacation. Rough Sets Theory, a Data Mining technique that can easily manage also categorical variables, is suitable for...

This paper defines temporal risk aversion in the context of a simple choice framework: that of time varying utility of wealth. The attention is focused on a decision maker who acts as a buyer: temporal risk premium, instantaneous risk premium and time preference premium are defined.
