Why was Marxs solution to the transformation problem inadequate?
Marx calculated the rate of profit on inputs evaluated at untransformed labor values. Marx seems to accept that his arithmetic examples are not fully worked out: The development given above also involves a modification in the determination of a commodity’s cost price. It was originally assumed that the cost price of a commodity equalled the value of the commodities consumed in its production. But for the buyer of a commodity, it is the price of production that constitutes its cost price and can thus enter into forming the price of another commodity.
