The term on the right hand side can be regarded as 
(11) 
am index of the growth of capital, if capacity is assumed 
to grow in proportion to capital ( Harrod's neutrality ). 
The implicit multiplier is the distribution parameter 
( 1 - ) which is the ratio of profit to price 
ft 
the profit margin - in the various lines of production; 
this is (multiplied by the utilisation rate/and)weighted

Equation (11) says nothing about how the growth rate 
I + C 
Y* 
is determined. To start with it is assumed to 
be given by the rate of innovations and by a kind of 
self-perpetuating force of the long run growth in the past. 
The equation (11) should serve to illustrate the role 
of the distribution parameters. 
If some of the gross profit margins ( mark-ups ) increase, 
given the growth rate of the capital, then some of the 
utilisation rates will have to decrease in relation to 
the break-even point u q . But the break-even point will 
itself also have to decrease, as can be seen from 
gross 
equations (4) and (8) unless the increase in profit margins 
is compensated by a rise in f ixled cost as a ratio of 'JUyUtA.
