this condition is more restrictive than the condition (131-8)
which is valid in a more general case. It could have been
derived a priori by observing that for invariant values of the
functions (8) and (0) over time the effect of growth of Re
s to reduce © in comparison with ©. It thus follows that ©
seems to be a better indicator of the lengthening of the production

 process than 6.
[t can thus be seen that while the various formulae giving
Res (0) and © are dependent on the hypothesis that the rate
of growth ¢ of primary national income R, is constant, the
sreceding formulae are independent of this assumption.
