we hypothesize that average productivity increases with in 
creases in P (and presumably increase in spatial decentraliza 
tion)? Would this increase of average productivity in the early 
stage be at an increasing rate (curve BB) or decreasing rate 
(curve AA)? If it is at an increasing rate, can it be presumed 
to reach a point where it is at a constant rate (point X, 
curve BB) and then a decreasing rate with still greater values 
for P (and presumably still higher degrees of spatial decentral- 
ization)? Further, at some later point, at a relatively high 
value for P (and presumably a relatively high degree of spatial 
decentralization), can average productivity be posited to fall off 
fas in curve * °° ™
