This is a response to Ajit's (3833). I am sorry that I am falling further
behind in responding to others. I hope to have more time next week.
Ajit, to begin with, I really do not appreciate your condescending
personal insults. I am trying to engage in serious debate and consider
your points and criticisms seriously, and respond to them at some
length. But you respond with insults. I have been trying to ignore the
insults and carry on the debate, but unfortunately the ratio of insults to
serious debate increased sharply in your last post. So, I ask you to
please dispense with the insults and continue with the debate.

Ajit, I am afraid that you haven't explained it even once yet. I have
argued that Marx's theory concludes that the magnitude of surplus-value is
proportional to surplus labor-time, with m as the factor of
proportionality (i.e. S = m Ls). Why isn't this determination up to a
factor of proportionality? Please be specific. What more is needed to
make this equation determination up to a factor of proportionality? If m
were determined, then the absolute magnitude of S would be
determined. But if m is not determined, then the magnitude of S is
determined up to a factor of proportionality. Why not?
I would really appreciate some comments by other listmembers on this key
specific point. How else are we going to resolve this dispute? Am I
missing something or is Ajit? If Marx's theory concludes that S = m Ls,
doesn't this determine S up to a factor of proportionality? If not, why

I have already answered your criticisms of "inconsistency" in previous
posts. That is not what this post is about. This post is about Marx's
failure to explain the determination of m. I acknowledge that the lack of
determination of m is a weakness of Marx's theory. But all theories have
weaknesses (elements of indetermination, etc.). So the question of
weakness inevitably becomes a question of RELATIVE or COMPARATIVE
weaknesses. If the weaknesses of other theories are even greater than
Marx's lack of determination of m, then this lack is not a reason to
reject Marx's theory.
Readers, please note that Ajit has not answered my argument that Marx's
theory is superior to Sraffa's theory in the sense that Marx's theory
explains the necessity of money and Sraffa's theory does not.

I am talking about Marx's derivation of the necessity of money in Section
3 of Chapter 1. What is wrong with Marx's argument in this section? If
there is nothing wrong, then this is a clear element of superiority of

I have read Sraffa many times (although I gladly acknowledge that I do not
understand Sraffa's theory as well as Ajit and others), and I have known
for a long time that Sraffa's system only determines relative numeraire
prices. What occurred to me recently is the similarity between Sraffa's
determination of relative prices and Marx's determination of surplus-value
- in the sense that both are types of determination up to a factor of
proportionality. In other words, the very weakness that you criticize
Marx's theory for, Sraffa's theory also has. Therefore, this weakness is
no reason to choose Sraffa's theory over Marx's theory.
Instead of responding to this argument, Ajit insults my scholarly
integrity by asserting that I have been writing about Sraffa without

Marx's prices are indeed in terms of gold, but they are in terms of an
absolute quantity of gold (or of money representing gold); e.g. 30
shillings, 600 pounds, etc. in Marx's many examples). In this sense,
Marx's money prices are absolute prices; they are not ratios of absolute
Sraffa's relative prices, on the other hand, are ratios of absolute
prices. The absolute prices are never determined, only the ratios between
Ajit, what exactly are these absolute prices that appear in Sraffa's
system of equations, prior to the selection of a numeraire and the
determination of relative prices. How exactly are these absolute prices
defined? In terms of gold or what? Could you please give me some
references where Sraffa or others have discussed the definition of these
absolute prices? Thanks.

Readers, please note that my serious criticism of Sraffa's theory - that
its numeraire prices, especially with the standard commodity as the
numeraire, have nothing to do with real world prices - is met, not with a
response to this criticism, but with another personal insult. The insult
is not appreciated and the criticism remains unanswered.

This is similar to what I am saying about the role of m in Marx's
theory. If m changes, all the absolute monetary magnitudes change
proportionality, so the ratios among these monetary magnitudes remain the

Again, a serious criticism - that it is better to have a partial
explanation of real world prices than a partial explanation of
hypothetical numeraire prices - is met with an insult. Again, the
criticism remains unanswered.

I look forward to further discussion (without the insults, please).
