i just uploaded another screenshot as a correction for below question

【 4 】 Consider an individual who lives for two periods. The individual has no initial wealth and earns (exogenous) labor incomes of amounts Y1 and Y2 in the two periods. The individual can borrow and lend at a fixed interest rate r. The individual’s lifetime utility function is given by U = ln C1 +   1   ln C2, where ρ is the rate of time preference.

Also consider the government that “lives” for two periods.   The government finances     its spending tt1 either by imposing lump-sum tax T1 or by issuing bond B1 in the first period. In the second period, the government needs to redeem the debt (and cannot issue bond B2 = 0). The first and second period government budget constraints are therefore tt1 = T1 + B1 and tt2 + (1 + r)B1 = T2 respectively.

What is the individual’s lifetime budget constraint?

What is the government’s “lifetime” budget constraint?

Find the first-order condition (Euler equation) for the consumer?

Assume ρ = 0.1, r = 0.1, Y1 = 120 and Y2 = 330. Find the optimal consumption path (C1, C2) when tt1  = tt2  = T1  = T2  = 0.

Now suppose that the government spending in the first period becomes tt1 = 21, which is all financed by tax in the same period. Find the optimal consumption path in this case.

Suppose instead the government spending in the first period tt1 = 21 is all financed    by issuing bond. Find the optimal consumption path in this case.

Now consider a situation in which the individual faces a liquidity constraint. That is, he cannot borrow at all (but can lend). Repeat (4)-(6).

His consumption in the first period is !C1 and his consumption in the second period is C2. He can lend and borrow at zero real interest (!r = 0 ).

(Intertemporal Choice )Consider a consumer whose preferences over consumption today and consumption tomorrow are represented by the utility function U(c1,c2)=lnc1 +?lnc2, where c1 and c2 and consumption today and tomorrow, respectively, and ? is the discounting factor. The consumer earns income y1 in the first period, and y2 in the second period. The interest rate in this economy is r, and both borrowers and savers face the same interest rate. (a) (1 point) Write down the intertemporal budget constraint of...

Question 2: Consumption Decisions Suppose a person's life is divided into two main blocks, periods 1 and 2. The consumer does not desire to perfectly smooth consumption over the two periods. In particular, preferences are such that c2 = 0:5 c1. Income in the two periods is equal to y1 = 500 and y2 = 1000, and income taxes are proportional 1 = 50% and 2 = 50%. The real interest rate is r = 0%. (a) What is the...

Tom has preferences over consumption and leisure of the following form: U = ln(c1)+ 2 ln(l)+βln(c2), where ct denotes the stream of consumption in period t and l, hours of leisure. He can choose to work only when he is young. If he works an hour, he can earn 10 dollars (he can work up to 100 hours). He can also use savings to smooth consumption over time, and if he saves, he will earn an interest rate of 10%...

Assume the representative consumer lives in two periods and his preferences can be described by the utility function U(c,c′)=c1/3 +β(c′)1/3, where c is the current consumption, c′ is next period consumption, and β = 0.95. Let’s assume that the consumer can borrow or lend at the interest rate r = 10%. The consumer receives an income y = 100 in the current period and y′ = 110 in the next period. The government wants to spend G = 30 in...
