6 Effects of changes in 9 on the equilibrium values for cc=0.5, (J=5.0, y=0.75, 8=0.25 14
7 Typical evolution of population averages (approaching the economic equilibrium) where
the parameters satisfy the conditions (12) and (13); a=0.5, p=5.0, y=0.75, 8=0.25,
9=am/n=0.01, e™^ ameo^ .0, no=2O, mb=600, x=0.7, ^=£=0.001 16
8 Influence of the limitation of police enforcement efforts on the short and long run evolu¬
tion of population averages; for x=0.5, P=5.0, y=0.75, 8=0.25, 9=am/n=0.01, emax=0.55,
ama*=1 0, no=2O, mo=6OO, x=0.7, ^=£=0.001 18
9 Influence of the level of minimum income on the short and long run evolution of popula¬
tion averages for a=0.5, p=5.0, y=0.75, 8=0.25, 9=0.01, am^O.35, ema^LO, no=2O,
mb=600, x=0.7, u=t=0.001 19
10 Influence of the level of minimum income on the short and long run evolution of popula¬
tion averages, and visualization of a relapse at f=40; for cc=0.5, p=5.0, y=0.75, 6=0.25,
6=0.01, a,n,n=0.35, emax=1.0, no=2O, mo=6OO, %=0.7, |i=^=0.001 19
11 Long run simulation outcomes and equilibrium values, respectively, for dealers and police
units; for cc=0.5, P=5.0, 9=0.01, am/n=0.1, emiW=0.55, no=2O, mb=600, x=0.7, u=t=0.001. 21
