where A(t + 1) = (1+ g) A(t), with A (0) > 0 and g > 0.
(a) Define a competitive equilibrium and the steady-state equilibrium.
(b) Characterize the steady-state equilibrium, and show that it is globally stable.
(c) What is the effect of an increase in g on the equilibrium?
(d) What is the effect of an increase in β on the equilibrium? Provide an intuition for this result.
