An adequate treatment of extended reproduction requires 
that we consider two stages separately: 
1. Outlay ( disposition of resources ): 
I II 
W, 
Gross investment 
capitalist's 
consumption 
Wage Bill 
This consists of constant capital which is equivalent 
to gross investment (if we consider an integrated department 
in which the item raw material concels out ), of capitalist 
consumption and of wages paid out ( which, as in Marx, are 
assumed to be fully spent on consumption ). 
2. The second stage is realisation. 
The demand for the output of each of the departments 
can be derived from the first stage: 
°1 + C 2 * °1 
W 1 + W 2 * °1 + =2 = °2 
The division of the whole into wages and gross profits P 
(gross surplus ) results as follows: 
0n " W 2 = P 2 W 1 +C 1 + c 2’

- W 1 ■ P 1 = C 1 + C 2 - W 1 •

+ C 1 * °2 = P 1 + P 2 
P 1 - 
by the sum of investment outlay and capitalist's 
cpnsumption ( Kalecki ).
