The problem, as I have explained in an earlier post, is that Sraffian theory (in which all capital is treated as circulating capital, because fixed capital is treated as a “joint product”), all industries must be assumed to have the same turnover period, if the rate of profit that is determined by the system of equations is to be equalized over the same period of time. If, on the other hand, turnover periods were not equal across industries, then the rate of profit determined by the equations would be equalized for different turnover periods, which would mean that the annual rate of profit for different industries would not be equal, contrary to the prevailing tendency. For example, if a given capital in one turnover period has a rate of profit of 5%, and it turns over twice a year, then it will have an annual rate of profit of 10%. If another capital in another industry also has a rate of profit of 5%, but turns over 10 times in a year, then its annual rate of profit would be 50%. I hope this clarifies the problem. Any suggested solutions? Fred ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
