Example 4.11; the oligopoly model with intertemporal demand interaction and adaptive
adjustment in the discrete time case. The phase space for the N-firm symmetric model with iso-
elastic price function and linear cost functions.

is empty if L>A=.4c/. In this case the capacity
constraint is ineffective since it is larger than the maximum value attained by
z
(see also Fig. 1.9). In Fig. 4.12 these regions are shown for the case L<A=.4c/.
This kind of subdivision is important for the computation of the equilibrium
points. In fact, the map in the different regions is given by the expressions
