Abstract

Dado un sistema tipo Leontief (o Leontief - Sraffa), se demuestra que puede ser transformado en uno estructuralmente equivalente que denominaremos sistema homogeneizado en el que la matriz tecnológica A así como la inversa de Leontief poseen propiedades matemáticas relevantes relacionadas con el autovalor máximo a de A. Para un sistema homogeneizado es condición necesaria y suficiente para que los precios relativos en el sentido Sraffa permanezcan invariantes al modificar el tipo de beneficio, que los coeficientes de trabajo directo sean iguales. Asimismo para este tipo de sistemas, la razón entre la suma de las mercancías que componen el excedente y la suma de las mercancías utilizadas como medios de producción coincide con el tipo máximo de beneficio. Es lo que Sraffa denomino “razón patrón” (global) en su Sistema Patrón.
