Hi. Solow criticized the assumption of equal rates of SV, on the ground that there is no mechanism that can bring about that equalization. He contrasted that case with the equalization of profit rates, which, in the absence of impediments to the movement of capital, is brought about by intersectoral capital flows.

	Thanks Jerry! It sounds more like a critique of Marx
	rather than Sraffa. Are you sure he criticised the
	assumption of equal rate of surplus value and not
	equal rate of profits? cheers, ajit sinha
