Comonotone lower probabilities with robust marginal distributions functions

open access: yesRevista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2022
AbstractOne of the usual dependence structures between random variables is comononicity, which refers to random variables that increase or decrease simultaneously. Besides the good mathematical properties, comonotonicity has been applied in choice theory under risk or in finance, among many other fields.

Nearly Comonotone Approximation of Periodic Functions

open access: yesAnalysis in Theory and Applications, 2017
Suppose that a continuous $2\pi$-periodic function $f$ on the real axis changes its monotonicity at points $y_i: -\pi\le y_{2s}< y_{2s-1}< \cdots< ...

Worst portfolios for dynamic monetary utility processes

open access: yes, 2017
We study the worst portfolios for a class of law invariant dynamic monetary utility functions with domain in a class of stochastic processes. The concept of comonotonicity is introduced for these processes in order to prove the existence of worst ...

Optimal risk-sharing rules and equilibria with Choquet-expected-utility. [PDF]

open access: yes
This paper explores risk-sharing and equilibrium in a general equilibrium set-up wherein agents are non-additive expected utility maximizers. We show that when agents have the same convex capacity, the set of Pareto-optima is independent of it and ...

Efficient Allocations under Ambiguity [PDF]

open access: yes, 2013
Important implications of the expected utility hypothesis and risk aversion are that if agents have the same probability belief, then consumption plans in every efficient allocation of resources under uncertainty are comonotone with the aggregate ...

Quasi-Monte Carlo methods for Choquet integrals [PDF]

open access: yes, 2015
We propose numerical integration methods for Choquet integrals where the capacities are given by distortion functions of an underlying probability measure.

Conditions for Choquet integral representation of the comonotonically additive and monotone functional

open access: yesJournal of Mathematical Analysis and Applications, 2003
In the paper a locally compact space \(X\) is considered. Two real functions \(f\), \(g\) are comonotonic \((f\sim g)\) if \(f(x)< f(x')\) implies \(g(x)\leq g(x')\). A functional \(I\) is comonotonically additive, if \(f\sim g\) implies \(I(f+ g)= I(f)+ I(g)\) and \(f\leq g\) implies \(I(f)\leq I(g)\).

Anti-comonotone random variables and anti-monotone risk aversion [PDF]

open access: yes
This paper focuses on the study of decision making under risk. We first recall some model-free definitions of risl aversion and increase in risk. We propose a new form of behavior under risk that we call anti-monotone risk aversion (hererafter referred ...

An easy computable upper bound for the price of an arithmetic Asian option. [PDF]

open access: yes
Using some results from risk theory on stop-loss order and comonotone risks, we show in this paper that the price of an arithmetic Asian option can be bounded from above by the price of a portfolio of European call options.

Diversification, convex preferences and non-empty core in the Choquet expected utility model [PDF]

open access: yes
This paper explores risk-sharing and equilibrium in a general equilibrium set-up wherein agents are non-additive expected utility maximizers. We show that when agents have the same convex capacity, the set of Pareto-optima is independent of it and ...
