Quoting Ian Wright <wrighti@ACM.ORG>: > > von Neumann does track growth of capital stocks in a similar model of ** > > proportionate ** growth using non-unitary matrices, so I infer that the > same thing could > > be done with Sraffa's. > > Yes it can. But the non-unitary matrix employed in proportionate > growth models (e.g., Pasinetti in his Lectures on the Theory of > Production) is merely the result of the representational choice of an > open model. One can just as easily model proportionate growth in terms > of a closed model with a unitary matrix. In this case, as before, a > surplus is produced, its scale grows exponentially over time, but its > distribution to households is specified. Per-capital consumption is > constant. > I dont see how you get a unitary matrix since if we multiply the net output vector by the technology matrix we get a net input vector that is a scalar multiple less than one of the output vector.
