I think the following correction to ope-l 5152 is needed:
The following topics, which were listed under "Sraffa's Non-Proof," concern
the self-contradiction in Ajit's price theory, not Sraffa's non-proof:
"Abstract prices or absurd, self-contradictory prices"
"Can Ajit's price theory fly?"
"censoring Ajit?"
"Used cars"
The last of these has also incorporated unrelated topics.
