Present value of each student’s income.

Answer to Problem 14.3P
The present value of income is $100,000
Explanation of Solution
Given Information:
It is known that,
Above budget constraint shows Consumption in present period and in future period is equal to total income earned.
Since,
The present value (PV) of D$ is
The Income this year is $50000.
So the present value is given below.
The income next year is $55000. Present value using this income is calculated as follows.
Therefore, the present value of income is $100,000.
Introduction:
Present discounted value means an amount to be paid or invested today to get regular income in future. It is usually done to know the real interest rate in an economy for the investment done.
b)
Condition for maximizing utility.

Answer to Problem 14.3P
He must consume times of consumption this year in next year.
Explanation of Solution
Given Information:
For utility maximization, marginal rate of substitution is equal to the price ratio.
For roommate P,
The price ratio is
In equilibrium,
For utility maximization of roommate P, he must consume times of consumption this year in next year.
Introduction:
Utility is the satisfaction dervied from consumption of good or services. To calculate satisfactifaction, it is given numeric form called utils. Util is the unit to measure utility. More the utils, more is the utility derived.

Answer to Problem 14.3P
saving this (present) year is $25000 and there is a dissaving of $27500 in next year.
Explanation of Solution
Given Information:
Now according to the third condition, put
Similarly,
For roommate P, saving this year is $25000 and there is a dissaving of $27500 in next year.

- Assume that consumption when young and consumption when old are both normal goods. The income effect of an increase in the interest rate will result in Group of answer choices an increase in saving when young. an increase in saving when old. a decrease in saving when young. a decrease in saving when old.arrow_forwardAssuming that the substitution effect is large relative to the income effect, tax reform designed to increase saving a. increases the interest rate and decreases spending on capital goods. b. increases the interest rate and increases spending on capital goods. c. decreases the interest rate and increases spending on capital goods. d. decreases the interest rate and decreases spending on capital goods.arrow_forward2. Utility maximization - Trading off labor and leisure The indifference curves on the following graph show Simone’s preferences for leisure and consumption for increasing levels of utility, such that her utility increases in both consumption and leisure. Assuming that Simone spends 68 hours each week sleeping, she has a maximum of 100 hours available to her for leisure if she does not work at all. Initially, she works 50 hours (and thus has 50 hours of leisure) and earns $400 per week. Use the grey point (star symbol) to indicate Simone’s initial leisure/consumption bundle. Dashed drop lines will automatically extend to both axes. [Please see the image attached] Now, suppose that Simone is laid off, but she is eligible to collect unemployment benefits of $350 per week. Use the black point (cross symbol) to represent Simone’s unemployment point on the previous graph when she consumes $350 per week and has 100 hours of leisure. Suppose that after a month of…arrow_forward
- b. Using Fisher's Intertemporal Choice model, consider the following scenario:i. Suppose Milo earns $1,750 in the first period and $2,500 in the second period. If he consumes $1,200 in the first period and $1,550 in the second period, what is the interest rate? ii. Now if Milo’s consumption changes to $1,800 in the first period and $2,000 in the second period, what is the new interest rate? c. Graphically depict and explain the Consumer’s optimum in the Fisher’s Intertemporal Choice Model.arrow_forwardwe use the Fisher model to discuss a change in the interest rate for a consumer who saves some of his first-period income. Suppose, instead, that the consumer is a borrower. How does that alter the analysis? Discuss the income and substitution effects on consumption in both periods.arrow_forwardA family of four has an income of $15,000 today and will earn $24,000 tomorrow. i). If the family consumes $11,500 in the first period and $15,000 in the second period, whatis the interest rate? ii). If the family consumes $15,000 in the first period and $13,500 in the second period, whatis the interest rate? iii). Explain the income and substitution effects and discuss which effect dominated after theinterest rate change from part (a.) to part (b.).arrow_forward
- Consider a consumer that lives only for two periods. He works in period 1 (and gets income Y1) and moves up the corporate ladder in period 2 (and gets income Y1 < Y2). This consumer has the usual preferences over time: u(C1) + βu(C2) 1. Assume this consumer cannot borrow. What is the consumption in period 1 and period 2? Display graphically. Show the corresponding utility curve. 2. Assume that now the consumer is allowed to save or borrow. Write down the new budget constraint. What is the consumption in period 1 and period 2? Display graphically. Could the consumer be worse off? Could the consumer be better off? Draw budget constraints such that for one of them consumer prefers to borrow and for the other - prefers to save. 3. Assume once again that a consumer cannot borrow, but can borrow and immediately sell some MacGuffins, and in the next period, the consumer must buy back the MacGuffins to return to the lender. Assume that MacGuffin t r a d e s a t P1 > 0 in the first period…arrow_forwardJoanne has just completed high school and is trying to determine whether to go to junior college for two years or go directly to work. Her objective is to maximize the savings she will have in the bank five years from now. If she goes directly to work, she will earn $22,000 per year for each of the next five years. If she goes to junior college, for each of the next two years she will earn nothing—indeed, she will have to borrow $6,000 each year to cover tuition and books. This loan must be repaid in full three years after graduation. If she graduates from junior college, in each of the subsequent three years, her wages will be $41,000 per year. Joanne’s total living expenses and taxes, excluding tuition and books, equal $15,000 per year. Instructions: Enter your responses as whole numbers. a.

- Assume that consumption and leisure are perfect complements, that is, the consumer always desires a consumption bundle where the quantities of consumption and leisure are equal, that is, C=L 1) (Denote the total hours of time available by h, the real wage by w, the real dividend income from firms by pi (π), and the lump-sum tax by T. Write down the consumer’s budget constraint. 2) Determine the consumer’s optimal choice of consumption and leisure. 3) Assume that there is an increase in w . Show how the consumer’s optimal consumption bundle changes. Explain with reference to income and substitution effectsarrow_forwardAssume that someone has inherited 2,000 bottles of wine from a rich uncle. He or she intends to drink these bottles over the next 40 years. Suppose that this person’s utility function for wine is given by u(c(t)) = (c(t))0.5, where c(t) is each instant t consumption of bottles. Assume also this person discounts future consumption at the rate δ = 0.05. Hence this person’s goal is to maximize 0ʃ40 e–0.05tu(c(t))dt = 0ʃ40 e–0.05t(c(t))0.5dt. Let x(t) represent the number of bottle of wine remaining at time t, constrained by x(0) = 2,000, x(40) = 0 and dx(t)/dt = – c(t): the stock of remaining bottles at each instant t is decreased by the consumption of bottles at instant t. The current value Hamiltonian expression yields: H = e–0.05t(c(t))0.5 + λ(– c(t)) + x(t)(dλ/dt). This person’s wine consumption decreases at a continuous rate of ??? percent per year. The number of bottles being consumed in the 30th year is approximately ???arrow_forwardRue operates a food truck on Florida beaches, where she sells paninis and drinks, which she can sell for $8.00 and $4.00, respectively.
