Bis 
per head and the capital-output ratio y=C/R to be a very 
weak one in different countries over a given time span, and 
‘his is in conformity with observed facts. 
In practise, no statistical interdependence can be found be- 
tween real income per capita and the capital-output ratio y. 
While this coefficient has real influence, it is insignificant by 
comparison with the influence of other factors. 
It can thus be seen that the theory presented leads to the 
expectation of, and provides an explanation for, a weak re- 
lationship between real income per capita and the capital output 
coefficient. 
Such a finding demonstrates only the consistency of the 
model with observed facts. It does not prove that the assump- 
tion of logarithmic linearity of the production function is nec- 
sssarily correct. It is evident that there exists an infinite num- 
ber of production functions which imply a low interdependence 
of real income and the capital-output ratio. 
D) Weak Relationship over Time between Real Income per 
Cabita and the Cabital-Outbhbut Ratio 
319. As the coefficient ©, is assumed to be constant over 
time, the preceding formula leads to the expectation of a low 
relationship over time between real income per capita and the 
capital-output ratio, and again this corresponds to observation. 
But here again, no conclusion can be drawn other than that 
the model is consistent with real” -
