5. Considering the following supply and demand equations (20 Points):
ππ = 3π β 1
ππ = β2π + 9
ππ/ππ‘ = 0.5(ππ β ππ )
a) Find the expressions. π(π‘), ππ (π‘), and ππ(π‘). When π(0) = 1, is the system stable or unstable?
b) If the constant for the change of excess of demand changes to 0.6, this is:
ππ/ππ‘ = 0.6(ππ β ππ )
do π(π‘), ππ (π‘), and ππ(π‘) remain the same when π(0) = 1?
