Sraffa refutó la interpretación convencional de la historia del pensamiento económico como un camino de una sola dirección y construyó una reformulación de la teoría clásica del valor y la distribución. El propósito de este artículo es despertar el interés en la obra de Sraffa suministrando alguna evidencia de la fecundidad y originalidad de su pensamiento, aunque no es posible dar aquí una discusión completa de sus argumentos. El trabajo disipa algunas opiniones y mitos muy difundidos pero insostenibles acerca de las contribuciones de Sraffa. Quizá es este uno de los aspectos más apreciables del artículo dado que, por primera vez, se presenta la oportunidad de realizar un escrutinio de estas interpretaciones sobre la base de la obra, hasta ahora inédita, de Sraffa. La propensión analítica y crítica de Sraffa no se detenía no sólo cuando discutía la teoría marginalista del valor y la distribución o la teoría de Keynes, sino ni aún cuando sus ideas propias eran sometidas a escrutinio.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The article provides a brief overview of Piero Sraffa's unpublished papers, explains his main contributions to economics and why they represent one of the major challenges to marginalist economics developed in the last century. Sraffa effectively refuted the conventional interpretation of the history of economic thought as a one way avenue and also built a coherent reformulation of the classical approach to the theory of value and distribution. The purpose of the paper is to excite an interest in Sraffa's work by providing some evidence of the fecundity and originality of his thinking, although no thorough discussion of his arguments can be provided here. The article dispels some widespread, but untenable opinions and myths about Sraffa's contributions. Perhaps this is one of the most valuable aspects of this paper since, for the first time, an opportunity to scrutinize the available interpretations on the basis of his hitherto unpublished manuscripts is provided. Sraffa's questioning and critical bent did not come to a halt not only when he discussed the marginalist theory of value and distribution or Keynes's theory, but even when his own ideas were under scrutiny.]]></p></abstract>
