T.990 =1.08 
J,4958 =0.94 J. 199=0.68 
and the aggregate value 
Je — 0.02 
The price mechanism gives a similar fit in the observation 
range, 
s(v”)=0.58 s(p) 
Here the extrapolatory JaNus quotient (76) gives 
(88) J.495)=0.69 J 19 =0.01 
T1999) = 0.02 
and the aggregate quotient 
Ts =0.66 
Using the three relations of the system (36) to generate fore- 
casts by the chain principle, and applying the JANUS quo- 
tient (75) to the ensuing forecasts for price p,, the material gives 
the following quotients 
89) 
JUD = 36 JU =1.56 JU) =0.04 
and the aggregate 
J=o0.02 
According to (80) and (85) the Janus quotients (89) could be 
expected to be higher than in (88), but the forecast refers to 
only one sample series and here it so happened that the ten- 
dency did not materialize very clearly.
