Expected utility operators and coinsurance problem
Irina Georgescu
The expected utility operators introduced in a previous paper, offer a framework for a general risk aversion theory, in which risk is modelled by a fuzzy number . In this paper…
The interest rate for saving as a possibilistic risk
Irina Georgescu, Jani Kinnunen
In the paper there is studied an optimal saving model in which the interest-rate risk for saving is a fuzzy number. The total utility of consumption is defined by using a concept o…
A portfolio choice problem in the framework of expected utility operators
Irina Georgescu, Louis Aimé Fono
Possibilistic risk theory starts from the hypothesis that risk is modelled by fuzzy numbers. In particular, in a possibilistic portfolio choice problem, the return of a risky asset…
How the investor's risk preferences influence the optimal allocation in a credibilistic portfolio problem
Irina Georgescu, Jani Kinnunen
A classical portfolio theory deals with finding the optimal proportion in which an agent invests a wealth in a risk-free asset and a probabilistic risky asset. Formulating and solv…
Possibilistic investment models with background risk
Irina Georgescu
In the study of investment problem, aside from the investment risk the background risk appears. Both the investment risk and the background risk are probabilistically described by…
The effect of prudence on the optimal allocation in possibilistic and mixed models
Irina Georgescu
In this paper two portfolio choice models are studied: a purely possibilistic model, in which the return of a risky asset is a fuzzy number, and a mixed model in which a probabilis…
A Possibilistic and Probabilistic Approach to Precautionary Saving
Irina Georgescu, Adolfo Cristóbal Campoamor, Ana Maria Lucia Casademunt
This paper proposes two mixed models to study a consumer's optimal saving in the presence of two types of risk.
Compatible extensions and consistent closures: a fuzzy approach
Irina Georgescu
In this paper --compatible extensions of fuzzy relations are studied, generalizing some results obtained by Duggan in case of crisp relations. From this general result are ob…
Optimal prevention with possibilistic and mixed background risk
Irina Georgescu, Ana Maria Lucia Casademunt
In this paper the effect of posibilistic or mixed background risk on the level of optimal prevention is studied. In the framework of five purely possibilistic or mixed models, nece…
