Let
P
denote a price vector (price system) and let us write
P(P,
X) 
= 
P'X 
....
gross social product; 
(4) 
N(P,
X) 
= 
P'A
X 
.....total
material costs; 
(5) 
Y(P,
X) 
= 
P'Y 
.....national
income;

(6) 
W(P,
X) 
= 
P'CX 
.....total
wage fund;

(7) 
F(P,
X) 
= 
P'BX 
.....total stock
of capital; 
(8) 
M(P,X) 
= 
P'(IAC)X 
.....total profits
or surplus value 
(9) 

We shall examine the following aggregate relationships:
a(P,X) 
= 
N(P,X)/Y(P,X) 
..... material
costsincome ratio;

(10) 
b(P,X) 
= 
F(P,X)/Y(P,X) 
...... capitalincome
ratio;

(11) 
g(P,
X) 
= 
W(P,X)/Y(P,X) 
.... wagesincome
ratio;

(12) 
y(P,
X) 
= 
M(P,X)/W(P,X) 
......the
rate of surplus value

(13) 
f(P,
X) 
= 
M(P,X)/[N(P,X)+W(P,X)] 
......the
profitscost ratio

(14) 
d(P,
X) 
= 
M(P,X)/F(P,X) 
......the
average rate of profit

(15)
