Consider an OLG model in which N0 = 100, and the gross population growth rate is equal to n. Each
individual only receives y = 100 coconuts when he is young, and nothing when old. The monetary authority
introduces either M = 1000 or M = 2000 units of gold in the first period, and distribute them equally among
the old generation in that period. Gold can be used either as the medium of exchange or consumed like a
regular commodity, and it yields a utility equal to 5 units of the endowment (~v = 5). Finally, suppose the
individual preference is such that everybody wants to save, in real terms, y
1+ vt
vt+1
.
a. (4pts) Suppose gold can only be used as money, what is the value of v
g
t
for n = 1, M = 1000 or 2000,
and t = 1 or 2.
b. (3pts) What is the rate of inflation pt+1
pt
in each case, and what is the current (c1) and future (c2)
consumption, respectively?
c. (3pts) Which case is not stable and why? What is going to happen then? After the new equilibrium
is restored, what is the amount of monetary gold and non-monetary gold, respectively?
