Aspectos de la economía de Sraffa y extensiones a partir de su libro producción de mercancías por medio de mercancías

Abstract

This work attend on the book “Production commodities by means commodities” of one of the most important economists and less known than they have existed. Its work involves the greater revolution on the economic analysis and it is not limited the mentioned work. “Production commodities by means commodities” he is the best one and more justified attack than it has received the neoclassical and marginal theory of the “capital” and the consequence and supposed payment of the factors by with his marginal productivity. For the Sraffa economics the goods of “capital” are not different from the rest, but commodities -today we would say to goods and services- that are consumed directly or used to produce other commodities. In economy the significant one is what it is produced and how it is produced and not how it is consumed. From its discovery of the standard ratio, the Sraffa model relates prices, wages and profits in economies with surplus or without , “the capital” as dated work reduced, with constant returns to scale or not, joint production or not, fixed capital or not, and without displacements of production methods. Unlike the neoclassic and marginalistic economy that make supposed optimizers, marginal valuations and unique equilibrium that determine solutions without margin for the social confrontation, the economy of Sraffa are not deterministic, do not say to us how many and with what prices we must produce, like distributing and like to consume, but it establishes relations, conditions and limits between variables that gather aspects of the economic reality.
