1. W. Parys proved that value price deviations (measured by price value
ratio pi/vi) can be predicted by organic composition of capital vertically
integrated in price terms. pi/vi > pj/vj means that price of industry i
is far way form value than price of industry j.

2. He used an counterexample to prove that organic composition of capital in
labor values fails to predict value price deviations: Acording to
Parys Marx is wrong on this.

3. With such counterexample, I found that if apropiation of surplues is
used insted pi/vi as a criteria of distance, the conclusion will be
reversed: Parys is wrong and Marx is right.

My proposed criteria is:
If si/gi > sj/gj then price in industry i is far way than industry j

where

si is the share of industry i in total surplus
gi is the share of industry i in total profit.

Hence, both criteria may be contradictory is some circumstances.
I wrote a paper on this (it is in refering process), I cand send it by
request.

My preliminar conclusion is:

Andrew and Duncan pointed out the importance of redistribution of surplus
value among sectors. I agree with them. The correspondence between values
and prices can be analyzed with redistribution of surplues value with
amazing results.
