''On the differentiability of the benefit function''
( 2004, Vol. 4 No.5 )
 
 
The benefit function, introduced by Luenberger, provides a tool for well-defined cardinal comparisons of different bundles of goods. It also allows to study in an orignal way optimal consumers and firms choices, Pareto-optimality etc... In this note we prove that the benefit function is differentiable under standard conditions. This property is useful in order to study optimal choices.
