HI Allin > Ian, you are definitely off the rails here. Any magnitude with > dimension $/$ has to have a value of 1.0 in any sane system. Not at all. A capitalist invests $100 over a year and receives $10 return. The rate of profit is: 10/100 = 0.1$ per $ invested. On what grounds could you think that a ratio of values in the same units should necessarily equal 1.0? > The interest rate (or rate of profit) necessarily has a time > dimension, although "per annum" is generally implicit (and > also generally legally enforceable). Yes of course. But the period of production is *undefined*. In Sraffa's interpretation it is generally considered to be a "year". But there is no need to explicitly represent the length of the production period. > I offer you 50% on your money. You snap up the offer, but are > disappointed by the interest checks you receive.

Choose any length of time you wish in order to interpret the period of production represented by linear production theory. The rate of profit occurs over that time period. It does not have dimensions "1/time" as Paul suggested. That sounds like "waiting". Best wishes, -Ian.
