吉原直毅氏による「マルクスの基本定理」批判

抄録

This paper critically deals with an Analytical Marxian Professor Yoshihara's two critiques against the Fundamental Marxian Theorem. One is the possibility of positive profit without positive exploitation, under the condition of joint production and laborer's consumption choice. The other is so-called Generalized Commodity Exploitation Theorem, which claims value and exploitaion concept can be defined for all commodities not only for labor and thus positive profit is identical with exploitation of any commodity not only of labor. I shall show the former demonstration is wrong because it needs negative net production. If we limit net production to be non-negative and permit disposal, then the exploitation of his case turns to be positive. To answer the latter critique, we shall examine the dual system of the value equations and their corresponding optimization problem or utility function. Then we can confirm that if we define net production as the commodities disposable for human being or if we define utility function as that of human being, then the value concept consistent with the presupposition must be labor value and exploitaion concept must be that of labor.
