« Social freedom » and the respect of corresponding rights, as well as Pareto efficiency (a priori required by democracy), imply that taxes and subsidies (re)distributing income are based on given « natural resources », the main of which ?'by very far?' consists of individuals?' productive...

Efficient measures are often not implemented because of their potentially damaging effects on distribution, yet these distributional effects are scarcely studied in economics because of the idea that they are case specific. In this paper we show that when we can separate the effect on efficiency...

The last 20 years have seen a significant evolution in the literature on horizontal inequity (HI) and have led to two major and "rival" methodological strands, namely, classical HI and reranking. We propose in this paper a class of ethically flexible tools that integrate these two strands.

In this paper, we show that the third inverse stochastic dominances introduced by Muliere and Scarsini (1989) is nicely connected with the Yaari's dual model. We show especially that the third inverse stochastic dominance is closely linked with the non-negativity of third derivative of the...

The initial goal of this paper was to study how to characterize the behavior of an EU maximiser decision maler according to the sign of u[p], p-th derivative of his utility function. The answer is well-known for u', u'', has been studied for u''' (Menezes, Geiss ant Tressler, Kimball), u''''...

In a seminal paper, Kolm [14] introduces the principle diminishing transfer. This principle requires that a transfert from an individual with income x to one with income x - D(D 0) has a greater impact on social welfare the lower x is. On the other hand Mehran [15] and Kakwani [11] introduced...
