This paper analyzes the formation of a general rate of profit and the subsequent prices of production in the context of Marx’s two-sector scheme of expanded reproduction. We show that a consistent solution of the transformation problem can be derived by incorporating the original transformation procedure into the inter-temporal equilibrium framework provided by the scheme of accumulation. Previous solutions for the special case of simple reproduction are also examined, and it is shown that all these solutions rest on the restrictive assumption of constant wage rates.
