Consider an agent who lives for three periods but consumes only in periods two and three where the consumptions are denoted by Cz and cz respectively. Her utility is given by u (c2, c3) = log(c2)+ 3 log(ca), where 0 < 3 < 1 is the discount factor reflecting her time preference. She invests an amount e in education in the first period which she borrows from the market at a given interest rate r > 0. Her income in the second period is w - h(e) where w is a fixed wage rate per unit of human capital and h(e) is the amount of human capital that results from investment in education (e) in the first period. Assume that h(e) is an increasing and concave function of e. The agent repays her education loan in the second period. She has no income in the third period. But she can save (s) in the second period from her income on which she receives the return s (1+r) in the third period to meet her consumption ernenditure

Question

Based on the model in the image answer the following questions:

a. Write down agent period 2 and period 3 budget constraint separately. 

b. Set up the agent's utility maximization problem showing her choice of variables clearly. Write down the first order conditions for agent's utility maximization.

c. Derive the ratio of consumption in period 2 and period 3 i.e. c2/c3 in terms of the parameter of the model.

d. Explain how investment on the parameter,e, depends on value of B

Consider an agent who lives for three periods but consumes only
in periods two and three where the consumptions are denoted by
Cz and cz respectively. Her utility is given by u (c2, c3) = log(c2)+
3 log(ca), where 0 < 3 < 1 is the discount factor reflecting her
time preference. She invests an amount e in education in the first
period which she borrows from the market at a given interest rate
r > 0. Her income in the second period is w - h(e) where w is a
fixed wage rate per unit of human capital and h(e) is the amount
of human capital that results from investment in education (e) in
the first period. Assume that h(e) is an increasing and concave
function of e. The agent repays her education loan in the second
period. She has no income in the third period. But she can save
(s) in the second period from her income on which she receives
the return s (1+r) in the third period to meet her consumption
expenditure.
