Fairness risk measures

R Williamson, A Menon - International conference on …, 2019‏ - proceedings.mlr.press
Ensuring that classifiers are non-discriminatory or fair with respect to a sensitive feature (eg,
race or gender) is a topical problem. Progress in this task requires fixing a definition of …

Efficiency in pure-exchange economies with risk-averse monetary utilities

M Ghossoub, MB Zhu - arxiv preprint arxiv:2406.02712, 2024‏ - arxiv.org
We study Pareto efficiency in a pure-exchange economy where agents' preferences are
represented by risk-averse monetary utilities. These coincide with law-invariant monetary …

Law-invariant functionals on general spaces of random variables

F Bellini, P Koch-Medina, C Munari… - SIAM Journal on Financial …, 2021‏ - SIAM
We establish general versions of a variety of results for quasiconvex, lower-semicontinuous,
and law-invariant functionals. Our results extend well-known results from the literature to a …

Inverse portfolio problem with mean-deviation model

B Grechuk, M Zabarankin - European Journal of Operational Research, 2014‏ - Elsevier
A Markowitz-type portfolio selection problem is to minimize a deviation measure of portfolio
rate of return subject to constraints on portfolio budget and on desired expected return. In …

Kusuoka representations of coherent risk measures in general probability spaces

N Noyan, G Rudolf - Annals of Operations Research, 2015‏ - Springer
Kusuoka representations provide an important and useful characterization of law invariant
coherent risk measures in atomless probability spaces. However, the applicability of these …

Sensitivity analysis in applications with deviation, risk, regret, and error measures

B Grechuk, M Zabarankin - SIAM Journal on Optimization, 2017‏ - SIAM
The envelope formula is obtained for optimization problems with positively homogeneous
convex functionals defined on a space of random variables. Those problems include linear …

The center of a convex set and capital allocation

B Grechuk - European Journal of Operational Research, 2015‏ - Elsevier
A capital allocation scheme for a company that has a random total profit Y and uses a
coherent risk measure ρ has been suggested. The scheme returns a unique real number Λ …

Benchmark-based deviation and drawdown measures in portfolio optimization

M Zabarankin, B Grechuk, D Hao - Optimization Letters, 2024‏ - Springer
Understanding and modeling of agent's risk/reward preferences is a central problem in
various applications of risk management including investment science and portfolio theory in …

Uniqueness of Kusuoka representations

A Pichler, A Shapiro - arxiv preprint arxiv:1210.7257, 2012‏ - arxiv.org
This paper addresses law invariant coherent risk measures and their Kusuoka
representations. By elaborating the existence of a minimal representation we show that …
