A composition between risk and deviation measures
, 2018 The intuition of risk is based on two main concepts: loss and variability. In this paper, we present a composition of risk and deviation measures, which contemplate these two concepts. Based on the proposed Limitedness axiom, we prove that this resulting

Expected value, to a point: Moral decision‐making under background uncertainty
Noûs, Volume 59, Issue 4, Page 1093-1125, December 2025.Abstract Expected value maximization gives plausible guidance for moral decision‐making under uncertainty in many situations. But it has unappetizing implications in ‘Pascalian’ situations involving tiny probabilities of extreme outcomes. This paper shows, first, that under realistic levels of ‘background uncertainty’ about sources of value independent

Multidimensional Poverty Measures from an Information Theory Perspective [PDF]
This paper proposes to use an information theory approach to the design of multidimensional poverty indices. Traditional monetary approaches to poverty rely on the strong assumption that all relevant attributes of well-being are perfectly substitutable ...

Comonotonic measures of multivariates risks [PDF]
We propose a multivariate extension of a well-known characterization by S. Kusuoka of regular and coherent risk measures as maximal correlation functionals.

An axiomatic characterization of a two-parameter extended relative entropy
, 2010 The uniqueness theorem for a two-parameter extended relative entropy is proven. This result extends our previous one, the uniqueness theorem for a one-parameter extended relative entropy, to a two-parameter case.

, 2017 Masures are generalizations of Bruhat-Tits buildings. They were introduced to study Kac-Moody groups over ultrametric fields, which generalize reductive groups over the same fields.

, 2018 We define a new structure on a space endowed with convexities, and call it a fractoconvex structure (or, a space with fractoconvexity). We introduce two operations on a set of fractoconvexities and in a special case we show that they satisfy the laws for

What's beyond the human developement index? [PDF]
In this note, we firstly discuss Chakravarty (2003) axiomatic foundation of the Generalized Human Development Index (GHDI) then we pro- pose a different set of axioms through which a class of Foster-Shorrocks-like Human Development Measures phases out ...

GENERALIZED EXTERNALITY GAMES [PDF]
Externality games are studied in Grafe et al. (1998). We define a generalization of this class of games and show, using the methodology in Izquierdo and Rafels (1996 and 2001), some properties of the new class of generalized externality games.

Revisiting poverty and welfare dominance [PDF]
The paper reviews the theory of the measurement of poverty. The axiomatic theory is described and the axiomatic properties of poverty indexes are related to assumptions on the functional form of the poverty index function.
