Planned Price and the Labor Theory of Value

The multitude of conceptions of price formation have not yet led us out of a blind alley, although their authors and defenders unite in declaring their allegiance to the labor theory of value. An analysis of the structure of prices set in accordance with these conceptions shows that (with the exception of shadow prices) these prices are totally indifferent to the planned proportions of the national economy. Proportions change, but the prices are not functionally tied to these changes. Is not the labor theory of value, to which all the given conceptions appeal, to blame for all this? Obviously, the instrument is not to blame if people do not know how to use it. In any event, there is insufficient reason to blame the weapon for a badly aimed shot.
