Unequal Uncertainties and Uncertain Inequalities: An Axiomatic Approach
Gajdos, Thibault; Maurin, Eric - HAL - 2004
In this paper, we provide an axiomatic characterization of social welfare functions for uncertain incomes. Our most general result is that a small number of reasonable assumptions regarding welfare orderings under uncertainty rule out pure ex ante as well as pure ex post evaluations. Any social...
