Question
The individual's problem is to choose the consumption bundle (cı, C2) optimally.
Specifically,
max {u(с1) + u(с2)}
C1,C2,81
subject to the two budget constraints above. Using the Method of Lagrange, let
d, be the Lagrange multiplier on the period 1 budget constraint and A, be the
Lagrange multiplier attached to the period 2 budget constraint. The Lagrangean
can be written as
L(c1, C2, 81, A1, A2) = u(c1) + u(c2) + d1 [Y – P;c1 – s1] + A2 [(1+r)s1 – Pąc2] .

Consider the problem of an individual that has Y dollars to spend on consuming over
two periods. Let c1 denote the amount of consumption that the individual would like
to purchase in period 1 and c2 denote the amount of consumption that the individual
would like to consume in period 2. The individual begins period 1 with Y dollars and
can purchase c, units of the consumption good at a price P1 and can save any unspent
wealth. Use s, to denote the amount of savings the individual chooses to hold at the end
of period 1.
Any wealth that is saved earns interest at rate r so that the amount of wealth the
individual has at his/her disposal to purchase consumption goods in period 2 is (1+r)s1.
This principal and interest on savings is used to finance period 2 consumption. Again,
for simplicity, we can assume that it costs P, dollars to buy a unit of the consumption
good in period 2.
