INAL STATEMENT 
At the conclusion of this Study Week, we should like tu 
thank the President, Members and Chancellor of the Pontifical 
Academy of Sciences for their initiative in arranging an inter- 
national discussion of the problems of Econometrics and for 
their generosity and hospitality in putting at our disposal their 
exquisite and unique Casina di Pio IV. 
In the course of this Study Week, we have had the op- 
portunity to review and discuss many recent developments in 
‘he following branches of our subject: macro-economic decision 
models and development planning; optimal growth models; 
the problem of uncertainty in development programming; the 
influence of real capital on the growth of the real national 
income; fiscal policy and economic growth; regional planning; 
cost-benefit analysis; statistical tools useful in econometric 
planning; the foundations of dynamic econometric models in 
probability theory, and estimation procedures for econometric 
models. 
In addition to discussing the prepared papers, we also 
considered the paths that future research might profitably 
follow. Throughout our meetings, many different points of view 
were expressed and opinions varied considerably on a number 
of subjects; but general agreement was reached on the follow- 
ing statement and proposals. 
Although, as an organised science, Econometrics is barely 
a generation old, it has already made substantial progress and 
is attracting more and more attention and interest throughout
