SEMAINE D'ÉTUDE SUR LE ROLE DE L’ANALYSE ECONOMETRIQUE ETC. 865 
About one-half of industrial production consists of durable 
goods (1), and it can be taken that about 4 of the output of 
aon-durables is reinvested. Thus, it can be considered that 
18.59% of the labor produces primary inputs for durable goods. 
[t may also be considered that the construction sector’s activity 
results for the greatest part in the production of durable goods, 
while the corresponding figure for mining may be of the order 
of 50%, so that the corresponding percentage of the labor force 
for the two sectors is about 5%. The contribution of inputs 
from the trade sector to the production of durable goods can 
be estimated at some 209%, of its output, accounting for a 
further 4 4 % of the labor force. In total, the share of primary 
inputs in durables production arising in the industry, mines, 
construction and trade sectors adds up to a total of some 28% 
of primary income. 
It may not be unreasonable to assume that activity in the 
transport and governmental sectors (19.39) is distributed be- 
tween durables and non-durables in line with the average for 
other sectors, so that the total contribution to production of 
non-durables of sectors other than transport and government is 
“30 — 
[t follows from this set of estimates taken as a whole that 
the share of primary income going to non durables and invest- 
ment may be respectively of the order of
