The structure of the product and cost formation of means of production

We consider the cost formation of the means of production from positions of the theory of a duality of labor value. According to the theory of a duality of labor value, the cost of the product acts as the ratio of the value of the result to the value of the costs. It is proved that the value of the means of production as a special case is also dual and is formed as the ratio of labor to save labor costs. The theory of a duality of labor cost is used for interpretation of the theory of limit productivity of J. B. Clark.
