1. Introduction
The utility, along with the production function represents the key concepts of any microeconomic theory.
The utility always stayed in the center of debates and polemics of economical nature, from the simple
fact that while the rest concepts were more or less clear, it was often a nebulous especially in terms of
actual implementation.
At Physiocrats the concept of utility is confused with value, utility being in fact the difference between
the utility created and consumed, while the value is given by the difference between price and cost of
production (Ioan, 2017).
For Adam Smith, the utility is given by the value of use which is more a matter of individual and
subjective (Ioan, 2017).
In On the Principles of Political Economy and Taxation, David Ricardo says that the utility or use
value is a necessary condition of exchange value, but is not the unit of its (Ioan, 2017).
John Stuart Mill believes that the usefulness of a good is only its ability to satisfy a desire (Stuart, 1848).
A qualitative leap in the approach of the utility is brought by Carl Menger which, in his Principles of
Economics, introduces the concept of marginal utility.
The founder of the School of Lausanne, Leon Walras considers the final degree of utility as last intensity
needs met by a certain amount of goods consumed.
2. What is the Utility?
In most scientific works, utility or satisfaction is achieved by the consumption of a particular good or
unit of preferences for a specific good or basket of goods and services.
