Question 3) In a two-period world, a consumer's utility function is given by u(c1, c2) = ln(c1) + In(c2) where c1 and c2 are his consumption in the two periods. Denote his income in the two periods by m1 and m2 and the prevailing interest rate by r. (a) Derive the period-1 consumption function c1(r, m1, m2). (b) How much will this individual save in the first period if m1 = m2 = 220 and r = 25%? (c) Suppose the individual has an income of £220 in each period, and that the current prevailing interest rate is 20%. If there is an increase in the prevailing interest rate, we cannot predict how his behaviour will change because we do not know the relative strengths of the income and the substitution effects. True or false? Provide a graphical explanation that supports your claim.

Suppose interest rate is 10 % and consumer's utility function is given by U(C1,C2)=C1C2. Income in the first period is 100 and income in the second period is 121. a) Find optimal consumption is each period. b) Does the consumer borrow? In which period? How much? c) Show the answers on a diagram.
John has the following utility function U(C₁, C2) = min{c₁ + ac2, C2}, where C₁ and c₂ are his consumption in periods 1 and 2, respectively and a is some positive constant. Suppose John has $100 income in period 1 and $105 income in period 2. Prices in both periods are $1. Question 2 Part al Suppose a = 2. If John can freely borrow and lend at 5% interest rate what would be his optimal consumption in both periods? 1 Question 2 Part a2 Suppose a = 2. Now, John can lend at 5% interest rate, but can't borrow at all. What would be his optimal consumption in both periods? Question 2 Part bl Suppose a 0.5. If John can freely borrow and lend at 5% interest rate what would be his optimal consumption in both periods? Question 2 Part b2 Suppose a 0.5. Now, John can lend at 5% interest rate, but can't borrow. What would be his optimal consumption in both periods?
Assume a consumer has current-period income y = 200, future-period income y′ = 150, current and future taxes t = 40 and t′ = 50, respectively, and faces a market real interest rate of r = 0.05, or 5% per period. The consumer would like to consume according to the following utility function: U (c, c′ ) = ln(c) + ln(c′ ). Show mathematically the lifetime budget constraint for this consumer. Find the optimal consumption in the current and future periods and optimal saving. Suppose that instead of r = 0.05 the interest rate is r = 0.1. Repeat parts (a) and (b). Does the substitution effect or the income effect dominate?
Exercise 2 (The Saving Schedule). Consider a two-period economy populated by identical households with preferences defined over consumption in period 1, C1, and consumption in period 2, C,, and described by the utility function Assume that households are endowed with Y, kilos of apples in period 1 and with Y, kilos of apples in period 2. Let P, and P, denote the price of apples in periods 1 and 2. Households can save (or borrow) at the nominal interest rate i. Let r denote the real interest rate, so that the gross real interest rate is 1 +r = P, P, (1 + i). Let St denote saving in kilos of apples. 1. State the household's budget constraints in periods 1 and 2. 2. Derive the household's intertemporal budget constraint in terms of C1, C2, Y1, Y,, and r. 3.

Consumer's utility function for consumption in two periods is c1+30ln(c2). The interest rate is r, the income in the first period is 10, the income in the second period is 50. What is the formula for the demand for second-period consumption?

5. Suppose interest rates are zero and the consumer's utility is u(c_{1}, c_{2}) = (c_{1}, c_{2}) while the two incomes are (y_{1}, y_{2}) = (75, 125) . Find the optimal consumption in each period , and also indicate what financial transactions the consumer makes . Show the answers on a diagram .
When analyzing how borrowing and lending affect the consumer's budget constraint, we measure spending in the current time period on the horizontal axis and spending in the future time period on the vertical axis. Assume that the interest rate at which the consumer can lend and borrow is 10%, income in period 1 is $1000 and income in period 2 is $1200. The point of maximum current consumption can be expressed as 1000+ 1200/1.1. 1000(1.1) + 1200. 1000+ 1200 + .1 1000/1.1 + 1200/1.1 + 1.
