Nevertheless, for non trivial payoff functions, searching for efficient network structures turns out...

We investigate the normative foundations of two empirically implementable dominance criteria for comparing distributions of two attributes, where the first one is cardinal while the second is ordinal. The criteria we consider are Atkinson and Bourguignon\'s (1982) first quasi-ordering and a...

Conditional quantiles are required in various economic, biomedical or industrial problems. Lack of objective basis for ordering multivariate observations is a major problem in extending the notion of quantiles or conditional quantiles (also called regression quantiles) in a multidimensional...

The aim of this paper is to explore the connections between the time dimension of economic phenomena and that of natural ones within the context of global (joint emissions of the energy sector) or local (joint product of waste) pollutions affecting present and future generations. Discounting...
