岡山大学経済学会 Acta Medica Okayama 0386-3069 33 1 2001 労働価値概念の仮想性と現実性 53 65 EN Yutaka Wada The subject of this paper is to reveal the hypothetical character of labour−values of commodities based on the precise determination of the concept of labour−value. Labour−values of commodities are not the actual labour embodied in the commodities but the necessary labour to reproduce them under socially averaged conditions of production. The substance and the following three features of labour−values give the concept hypothetical character which has often been overlooked conventionally. (1) Labour−value of each commodity takes the form of labour commanded by the proportional money to the social necessary labour of the commodity and the command of labour by money stays in potentiality before the money is actually expended. (2) The aggregated amount of labour−value of commodities in an economy for a given period is more than that of labour necessary to reproduce the commodities under socially averaged conditions of production because the labour−values of commodities often constitute the parts of labour−values of other commodities as means of production. (3) The aggregated amount of labour−value of commodities in a department for a given period is not equal to that of labour necessary to reproduce the commodities under individual conditions of production because the compositions of homogeneous means of production are variable in each individual process of production and the variations necessarily cancel out neither in their own department nor in the economy as a whole. The hypothetical character of labour−value, however, does not mean the concept useless or unrealistic. Labour−values of commodities can indicate the unequal exchanges of labour under their equilibrium prices in a pure market economy, which exit behind the market prices of commodities as the centres of their fluctuations.

岡山大学経済学会 Acta Medica Okayama 0386-3069 30 3 1999 欧米における転化問題論争の現局面―1990年代の研究を中心に― 247 270 EN Yutaka Wada This paper makes a brief survey of the debate on the transformation problem in Western countries during the last decade. Many studies on the problem at this period have strong concern for the 'New Approach' proposed by Dumenil, Foley and Lipietz in 1980's and various evaluations of the 'New Approach' exist which are quite far from reaching any consensus. Szumski, Carchedi and Haan, for example, try to solve the problem in their criticisms ofthe 'New Approach'. Such situation reflects different views of the transformation problem. While the advocates of the 'New Approach' want to analyse the income distribution between capital and labour, its critics tend to consider prices of production as a consequence of capitalistic unequal exchanges of labour. According to the author, the second view is more appropriate on the transformation problem. The ultimate origin of incomes can be generally sought to productive labour expenses without introducing prices of production but the levels of incomes can be determined only after investigating prices ofproduction concretely. The author also points out that the debate in 90's has not progressed so rapidly as in and before 80's. No potential conflict of interest relevant to this article was reported.

岡山大学経済学会 Acta Medica Okayama 0386-3069 30 4 1999 転化問題における総計一致諸命題の実在的意義 213 237 EN Yutaka Wada Three aggregate equalities have been discussed in the transformation problem in Marxian economics: total value =total price of production; total surplus value = total profit; total value product = total revenue. Marx thought that all the aggregate equalities hold simultaneously but nowadays the following three views are opposed to each other: (1) One which denies all the aggregate equalities (2) One which holds anyone ofthe aggregate equalities (3) One which holds any two or three ofthe aggregate equalities. The first and the second views do not need any modification of the definition ofvalue and / or price ofproduction whereas the last view does. The author takes the second view to assume total value = total price of production for the analysis of unequal exchange of embodied labour. The other two aggregate equalities do not hold under the assumption. The author insists that it does not mean the failure of the labour theory of value because the inequality between total surplus value and total profit as well as the inequality between total value product and total revenue indicate the possibility of additional unequal exchanges of embodied labour beyond the redistribution of surplus value among capitals.

岡山大学経済学会 Acta Medica Okayama 0386-3069 28 4 1997 貨幣の必然性論の4類型 275 292 EN Yutaka Wada In this paper, Marxian attempts to demonstrate the necessity of money in market economy are classified into the four types of theory as follows : (1) one which focuses on money as the measure of value and does not use the concept of labour-value in the demonstration (2) one which focuses on money as the means of circulation and uses the concept of labour-value in the demonstration (3) one which focuses on money as the means of circulation and does not use the concept of labour-value in the demonstration (4) one which focuses on money as the measure of value and uses the concept of labour-value in the demonstration. The author thinks that the second type of theory should be adopted for two reasons. First, the concept of labour-value makes it possible to find out what set of social relations among individual labours makes money necessary as a means of social reproduction. Second, money as the measure of value can be meaningful only in an economy where money as the means of circulation is necessitated by indirect exchanges of commodities.

岡山大学経済学会 Acta Medica Okayama 0386-3069 28 2 1996 結合生産商品の労働価値規定―不等労働量交換分析の一環として― 127 142 EN Yutaka Wada According to the standard version ofthe labour theory of value, labourvalue of a product is defined as the social average of the amounts of labour embodied in the homogeneous products on the supposition that the scale of the production is appropriate to the social demand for the products. In case of joint products, the amount of labour directly and indirectly necessary for their production needs to be divided among individual joint products before calculating the average. In the labour division, the composition of demands for heterogeneous joint products must be considered because it will be different from the composition of the products which is fundamentally determined by the technical relations of production. The labour division among joint products, therefore; is understandable through two logical phases. First, without any consideration for the gap between demand and production peculiar to joint products, the amount of labour necessary for production is divided equally among categories of homogeneous joint products. Second, the division of necessary labour is modified by the consideration for the gap. The labour divided into unsold products is divided again among other joint products sold in higher proportions to production because the former are the useless by-products of the latter. The amount of labour commanded by each joint product may be further deviated from the average of its embodied labour after the modification. Labour-values of joint products should include the part of deviations which reflects the reduction of the gap at the markets. No potential conflict of interest relevant to this article was reported.
