Abstract
The non envy criterium, introduced by Tinbergen and convoqued by some theories of justice, cannot always be used to identify allocations which also satisfy the requirement of Pareto-optimality. This is the reason why it had been neglected for a while. Nevertheless, it is still useful in some contexts we would like to describe. In fact, recent conclusions of normative economy demonstrated that, in some conditions and even in the framework of production, this criterium provide a solution for fair allocations. Precisely, we would like, on the basis of these results, to determine which extent has the implementation of non envy criterium in order to identify fair distributive allocations in a context of exchange and production as well.
