Professor FRISCH’s model is also of great interest to the deve- 
loping countries because it takes into consideration, in a very imagin- 
ative way, of problems which have not been discussed or do not 
require consideration in connection with the more advanced countries. 
The point I am making is that model making and a good deal 
of econometrics, a very large part of it, very naturally and very 
properly had started on the basis of the experience of the advanced 
countries where already a good deal of structural stability had been 
reached. It was natural and also proper that such developments 
should have taken place. because these were useful for the advanced 
-ountries. 
On the other hand the approach of Professor Friscx and Dr. Pa- 
SINETTI is likely to prove extremely valuable to underdeveloped 
countries to supplement the tools already fashioned, and likely to 
be fashioned in future, to suit the requirements of advanced 
countries.
