There's no increase in productivity. The same hours of labour are performed each "period", producing the same physical outputs. (The actual quantities of the outputs are immaterial.) If we can't work this out on the simplifying assumption of no tecnical change, there's little hope of working it out with ongoing technical change superimposed. > >There's a problem though.

This line won't help you. Here was my last table: round: 46 c v profit price pvratio I 243.00 81.00 96.00 420.00 1.1200 II 108.00 108.00 64.00 280.00 0.9333 III 54.00 81.00 40.00 175.00 0.8750 Tot. 405.00 270.00 200.00 875.00 1.0000 On the interpretation you're proposing, how are you going to write the next table? You'll have to put 420.00 at the foot of the "c" column and 280.00 at the foot of the "v" column as these "greater quantities" of output are put to use. If you write 200 for aggregate profit, you've then got an aggregate price of 900, not equal to total value. > So far you have not responded to me at all.

Rakesh, I thought we'd agreed that the transformation as such, in Marx, is an atemporal comparison of hypothetical states: here, with prices equal to values; there, with prices such as to yield a common rate of profit. The "same economy" with different sets of prices. So why are you talking about changes in labour productivity? Allin.
