I think the difference comes down to Ian always using flow
quantities and abstracting from the time duration. Allin and
I are used to processing econometric data in which circumstances
one can not allow oneself such strong abstractions so what
seems all the same to Ian seems a serious problem to us.

In a way this is the point. The simple example responds to your
introduction of a distinction between a "rental charge" and an
"ordinary price". If you understand that this is only a putative
distinction then my point is made.

I did not claim that any economic quantity has dimensions 1/time.
However, I think either Paul or you did, in the context of suggesting
that the price of money-capital was "economic nonsense" and "off the

You now agree that time is in the denominator of both quantities. Your
initial complaint about the price of money-capital was that it was not
quantitifed with respect to time. I explained no price is ever
quantified with respect to time. Nonetheless, a dimensional analysis
of the return to quantities of money-capital supplied is consistent
with the fact that an actual rate of return is received over a period
of time.

I am always willing to admit when I am wrong. In this particular
instance, however, I think the matter is clear. One day, no doubt, the
boot will be on the other foot.
