The previous discussion, as I recall,  centered around what would
constitute a refutation.  The meaning of repudiation is quite different,
though, from the meaning of refutation.

In the abstract that you posted, Okishio did not repudiate the
Okishio Theorem -- rather, he reaffirmed his belief in it within 
the context of comparative statics.

Yes, this is an issue that could be discussed.  E.g. one could ask
whether a  result from comparative statics that can't be extended to 
dynamic analysis has any meaning, heuristically or otherwise, for the 
study of  capitalism.  That question is related to one's perspective on 
the 'rules' of model-building or abstraction.

Right.  It doesn't have to.  Even if Okishio thought that the Okishio
Theorem was a comparative statics result,  any other author can
attempt (successfully or not) to show that the Theorem holds 
within a non-linear context.  The fate of a  theorem, once developed, 
is no longer necessarily or exclusively in the hands of its originator.
