Quoting Andrew Brown <A.Brown@LUBS.LEEDS.AC.UK>: > The only relevant things you can compare are unitless rates such as profit > rate or income shares. In some models, among them the Sraffa model, the rate of profit appears to be dimensionsless: it is the fraction by which capital increases over a cycle. Because the length of the cycle is set equal to 1, expressions such as (1+r) can appear in the equations. This does not make it dimensionless. It has the dimensions of "one over Time". A rate of profit is the ratio of a flow rate to a stock. Philip Dunn
