Optimal investment under behavioural criteria - a dual approach
We consider a discrete-time, generically incomplete market model and a behavioural investor with power-like utility and distortion functions. The existence of optimal strategies in this setting has been shown in Carassus-Rásonyi (2015) under certain conditions on the parameters of these power functions. In the present paper we prove the existence of optimal strategies under a different set of conditions on the parameters, identical to the ones in Rásonyi-Rodrigues (2013), which...

Premium evaluation for different loss distributions using utility theory
For any insurance contract to be mutually advantageous to the insurer and the insured, premium setting is an important task for an actuary. The maximum premium ( that an insured is willing to pay can be determined using utility theory. The main focus of this paper is to determine by considering different forms of the utility function. The loss random variable is assumed to follow different Statistical distributions viz Gamma, Beta, Exponential, Pareto, Weibull, Lognormal and Burr. The theoretical...

Rationality principles for preferences on belief functions
A generalized notion of lottery is considered, where the uncertainty is expressed by a belief function. Given a partial preference relation on an arbitrary set of generalized lotteries all on the same finite totally ordered set of prizes, conditions for the representability, either by a linear utility or a Choquet expected utility are provided. Both the cases of a finite and an infinite set of generalized lotteries are investigated.

Una aplicación de la teoría de la utilidad de Von Neumann a la probabilidad subjetiva.
En este artículo se da una condición necesaria y suficiente para la existencia y unicidad de una probabilidad subjetiva, finitamente aditiva, que concuerda con una probabilidad comparativa definida en una cierta clase de sucesos asociada al espacio paramétrico objeto de la inferencia.Nuestra constribución no evita tener que postular la relación de probabilidad comparativa en una clase mayor que la que es objeto de nuestro estudio pues exige la introducción de un espacio auxiliar que es el intervalo...

Utilidad de Von Neumann como función de conjunto.
En este artículo nos proponemos dar la caracterización axiomática de un criterio de decisión en ambiente de riesgo, entendiendo como tal una regla que selecciona un subconjunto de un conjunto dado. Este método de caracterizar un criterio de decisión parece más natural que el de suponer a-priori, es decir, como axioma, un preorden completo en el espacio de distribuciones de probabilidad. Adoptando este punto de vista se da una serie de axiomas de racionalidad que caracterizan el criterio de la utilidad...

Weighted entropies
We present an axiomatic characterization of entropies with properties of branching, continuity, and weighted additivity. We deliberately do not assume that the entropies are symmetric. The resulting entropies are generalizations of the entropies of degree α, including the Shannon entropy as the case α = 1. Such “weighted” entropies have potential applications to the “utility of gambling” problem.
