Abstract
In this paper we show that given a utility threshold Luenberger�s benefit function
correctly represents individual preferences as long as specific reference commodity
bundles are considered. We further show a condition which is sufficient for reaching
Pareto optimality that generalizes the zero-maximum principle proposed by Luenberger.
Under our hypothesis, the social benefit could be positive, negative or zero, and not
necessarily always zero
