Consider a single type of agent three-period
model of consumption/saving decisions, with
house- hold lifetime utility given by
U = In(c1) + Bln(c2) + B2ln(c3),
where B = 0.98. The household earns
exogenous income y1 = 10 in the first period, y2
= 11 in the second period and y3 = 13 in the
third period, and can borrow and save at the
real interest rate r1 between the first and second
periods and r2 between the second and third
periods. Assume that there are no taxes.
(a) Define an equilibrium.
(b) Compute the interest rates of equilibrium.
(c) Assume B = 0.99, compute the interest rates
of equilibrium. (d) Assume y2 = 12, compute the
interest rates of equilibrium.
