No, the concept of regulating capital appears mainly in the theories of
ground rent. In the discussion of the TP and also competiton (chs 8-10)
are at high level of abstraction and there is the assumption that
average conditions=to regulating conditions.

The answer is no, again I refer to my reply to AC but also see Mason's
comments.
