The axioms used to characterize the generalized Gini social evaluation orderings for one-dimensional distributions are extended to the multidimensional attributes case. A social evaluation ordering is shown to have a two-stage aggregation representation if these axioms and a separability...

One of the main research areas in Bayesian Nonparametrics is the proposal and study of priors which generalize the Dirichlet process. Here we exploit theoretical properties of Poisson random measures in order to provide a comprehensive Bayesian analysis of random probabilities which are obtained...

Concavity and supermodularity are in general independent properties. A class of functionals defined on a lattice cone of a Riesz space has the Choquet property when it is the case that its members are concave whenever they are supermodular. We show that for some important Riesz spaces both the...

Due to sub-Saharan Africa’s recurrent food-crises and enhanced difficulties to feed its growing population, calls for a Green Revolution – a substantially raised agricultural productivity by means of scientific modernization and supportive institutional reforms – are often aired. However,...

In economics, there is currently an important discussion on the role of "legal origins" or "legal families". Some economists claim that legal origins play a crucial role until today. Usually, they distinguish between Common Law, French, Scandinavian and German legal origin. When these legal...
