bution of industrial production, population, investment, consumption
 and other economic magnitudes? The latter question
suggests the need to develop a more adequate general interregional
 theory which encompasses the spatial distributions of
both economic activities and political-administrative-planning
functions and decision-making authority; and that these spatial
 distributions be simultaneously determined (1).
In what follows, I can only make a small beginning at the
formidable task which confronts us. I shall suggest hypotheses
which relate to:
I) the advantage (positive or negative) of increased participation
 potential with increase in the degree of spatial decentralization
 of decision-making authority (utilizing concepts
based upon the gravity model as developed in the field of
regional science):

2) the advantage (positive or negative) of increase in the degree
of spatial decentralization with respect to:
a) cost of collecting information
b) cost of processing information
c) cost of transmitting information
d) time-cost of executives, representatives and officials spent
in reaching a decision based upon the processed information
 made available;
3) the overview advantage (positive or negative) of increase in
the degree of spatial decentralization (where overview
advantage is defined in terms of the wisdom-full informationcoordination
 factor in decision making as reflected in the
writings of Professor J. MARSCHAK and his associates).
