Thus, we find for the percentage of the primary income
which is embodied in investment a figure which is of the same
order of magnitude as the figure which is given by the preceding
 analysis.

b) From Tables 8 and 9, some 5% and 20% of primary
income emerge in consumed income during the following quarter
 and year. These estimates seem also perfectly compatible
with the figures for the composition of the labor force given
above.
But it should be stressed that analyses based on considera-Hon
 of the breakdown of the labour force, given the present
state of the analysis must be considered as very rough, and
of indicative value only.

Determination of the Function «(0)

335. It does not appear to be absolutely impossible to determine
 the function (6) from an analysis of the composition of
‘he working population and available data on the structure
of production, at least on an approximative basis.
Unfortunately, this calculation involves a great deal of
work, and up to now I have not been able to find the time to
do it, even though the results of such an analvsis would clearly

It may well be, and in the author’s view it is quite likely,
that over the useful range of variation of 8 i.e. from o to 100
years, the exponential form
