Los aportes de Jevons, Menger y Walras al concepto de marginalidad.

Abstract

This work aims to describe the evolution of the marginality concept through the works of Jevons, Menger and Walras that constitute the consolidation of the pure economy. Through the review of its theoretical foundations supported by the law of diminishing utility, it is explained how the marginal relations of the subjective theory of value allowed the achievement of the producer's balance of the side and the justification of the maximization approach. By equating economics with an exact science, Jevons develops the scientific method in economics through its principle of equi marginality, Menger doesn’t solve a formal theory of the principle of diminishing utility but introduces the concept of opportunity cost to marginalism, Walras through general equilibrium, it lays the foundations for the further development of the marginal maximization approach. Differential calculation definitions are used based on the concept of partial derivatives to solve a case of profit maximization.
