No, because the two definitions of Ln are not the same. The Sraffian interpretation of Marxfs definition of Ln is the labor-time required to produce the means of subsistence (Lms). My interpretation of Marxfs definition of Ln is the labor-time required to produce a money equivalent to the variable capital, i.e. equal to the money wages paid to workers (Lw = V / m). These two definitions of Ln will in general not be equal because the variable capital (or the money wages) is equal to the price of the means of subsistence, which in general is not proportional to the labor-time required to produce the means of subsistence; i.e. V = Pms mLms. Therefore, I do not simply multiply a Sraffian equation by m. I have a different equation, because the two definitions of Ln are different. Plus, my equation for the rate of profit (equation (2)) is not the same as the Sraffian determination of the rate of profit, both for the reason given above, and also because Sraffian theory determines the rate of profit simultaneously with prices of production, not prior to prices of production. And, similarly, my equation for prices of production (equation (3)) is also not the same as the Sraffian determination of prices of production, for the same two reasons. > You also must have noticed that in your latest > "sequencial" determination, you did not start with a > given M. Implicitly, M was taken as given, because C and V were explicitly taken as given, and M = C + V, as I have said many times. I was trying to present a gvery brief summaryh of Marxfs logic of sequential determination, without having to repeat all the steps every time. > When logical consistency was called for, you > had no option than to fall back on the "Sraffians". Consistency does not require Sraffian theory. Marxfs theory, properly understood, also provides logical consistency. The argument for consistency in my last message was not based on any Sraffian equation; it was based on the same equations which express Marxfs theory which I have presented many times, this time in abbreviated form.
