of either a centralized system of decision-making, or a decen- 
tralized system. (?) His resulting figures would not be in- 
consistent with the hypothesis which states that an overview 
advantage does exist, and with the more concrete hypothesis 
that states that this advantage can be roughly depicted by 
curve CC of Figure 10. [In Figure 10, curve CC indicates a 
disadvantage (a negative Figure) for any degree of spatial 
centralization less than 100%]. The present author together 
with Tung has developed another example involving the invest- 
ment by a large merchandising firm of $1 million at each of 
several h*” order nodes (?). The resulting figures are also not 
inconsistent with the hypotheses underlving curve CC of Fi- 
gure IO. 
Clearly, neither of these two examples can be said to sup- 
port in any way whatsoever any hypothesis on overview 
advantage. À considerable amount of spade work has yet to 
be done in defining concents and terms before anv empirical
