Hi Diego Is not R in Sraffa's theory the maximun rate of profit? If so, it is a ratio > or quotient between two "things" that must have some (physical) dimension. > For instance, in Marxian theory, the rates of profit and surplus value are > also quotients. They have no dimension but are the ratios of quantities of > labour or money (measured in hours or euros). So, the rate of profit is an > (maximum) eigenvalue as well, but this pure number is the quotient of two > units that are in fact the same "thing". But again: which is the physical > unit of the standard commodity? It must have one and I cannot conceive of > nothing different from labour. The R is a scaling, so I think of it as the same percentage increase applied to the different units of commodity types. The physical unit of the standard commodity is a vector, as it is a bundle of goods. I don't see a problem here, unless I've missing something. -Ian.
