5. Consider a two-period consumption model in which an individual's life time- utility is u(c1,c2) =ce. The individual earns I1 = 1000 in period 1 and re- ceives a government pension I2 = 800 in period 2. Suppose the individual can save or borrow at the net interest rate 10% (r 0.1). Assume that the price levels in both periods are one (p1 = P2 = 1). (a) Find the individual's optimal consumption level in each period. How much does she save or borrow in period 1?. (b) Suppose the interest rate goes up to 40%. Find the total, substitution, and income effects on period 2 consumption. Based on your answer, would you classify period 2 consumption as normal or inferior? Is it Giffen? (c) Suppose the government wants to adjust the pension to I, so that the individual is equally well off as before the interest rate change. Find I. Is I, larger or smaller than I2? Give a brief, intuitive explanation of this result.

U(C1, C2) = c₁0.8 20.4 where c₁ is the quantity of current consumption goods and c₂ is the quantity of future consumption goods. Consider a consumer whose income is y₁ = 100 in the current period and y₂ = 140 in the future period. The consumer pays lump-sum taxes t₁ and t₂ == = 20 in the current period 10 in the future period. The real interest rate is r = 0.1, or 10%, per period. (a) Write down the consumer's budget constraint for each period and derive the consumer's lifetime budget constraint. What is the value of the consumer's lifetime wealth? [Note: Lifetime wealth is the present value of the consumer's lifetime disposable income] (b) Draw the lifetime budget line on the (C1, C2) plane with c₁ on the horizontal axis and C₂ on the vertical axis. Include the values of the intercepts and the endowment point in your graph. What is the slope of the budget line? (c) What are the two conditions that the consumer's optimal choice of (C1, C2) must satisfy? Find the consumer's optimal…
Consider an economy that is composed of identical individuals who live for two periods. These individuals have preferences over consumption in periods 1 and 2 given by U = /(C,) + (C2). They receive an income of 45 in period 1 and an income of 20 in period 2. They can save as much of their income as they like in bank accounts, earning an interest rate of 10% per period. They do not care about their children, so they spend all their money before the end of period 2. Each individual's lifetime budget constraint is given by C1 + C2/(1 + r) = Y1 + Y2/(1 + r). Individuals choose consumption in each period by maximizing lifetime utility subject to this lifetime budget constraint. (a) What is the individual's optimal consumption in each period? How much saving does he or she do in the first period? (b) The government has decided to set up a social security system. This system will take $10 from each individual in the first period, put it in the bank, and transfer it to each person with…
Consider the household model that you have seen in class but now assume that the goal of the household is to consume twice as much in period 2 as in period 1. She earns $100 in the first period and $150 in the second period. The interest rate is 5%. What is her optimal saving in the first period? Note: Type in your answer approximated to two decimal points, i.e., your answer must be of the form "999.99". I will not be able to fix correct answers that were entered incorrectly, such as "999.999" or "999,99" or "999". In case the last digit in the correct answer is zero, e.g., "999.90" or "999.00", Blackboard will automatically delete it and you should not do anything about it.
Suppose that a consumer/investor has an initial endowment only for the current period, which is Eo =450. She may consume today or in the next period only (two-period model). The interest rate for borrowing and lending in the capital market is 5% (a)Depict the budget constraint for the investor in an inter-temporal consumption diagram! What is the maximum amount the consumer is able to consume in the next period? (b)The consumption preferences of the consumer/investor are best described by a square root function, defined over current and future consumption. What is his optimal consumption plan? Show your calculations! Depict the results in appropriate diagram. Which amount is invested in the capital market?
APPLIED ECONOMICS Topic: Intertemporal Choice Levinn’s utility function is expressed as the following: U= C1 C2 0.3 where C1 is his first periodconsumption and C2 is his second period consumption. His income in the first period is$2500 and interest rate is at 10%. If at equilibrium, Levinn is neither a borrower nor a lender,then what is his expected income in the second period? Show the graph if possible
How does savings change with changes in y2? Provide some intuition behind this result.
Mary has income of $2000 today and $1000 tomorrow. She can lend and borrow at an interest rate of 20%. There is 10% inflation. Her preferences for intertemporal consumption are represented by the following utility function u(c, c) = min{c1, 2c2} (a) What is her optimal consumption bundle?
In an intertemporal optimizing model consumption, a consumer living from time zero (0) to time t has a longer utility: U (C)= ln C. The market interest rate is r and the consumer is assuming no inheritance. Derive the consumption relationship and the marginal utilities between two adjacent periods. Using a diagram, explain the time profiles of paths based on (i) above. Show that consumption is proportional to the present value of future income at time zero (0) at a given interest rate.
1) Helena earns $2000 this year and will earn $1500 the next year. The interest rate between each year is 10%. She wants to consume the same quantity each year. She wants to have spent all her money by the end of year 2. Warning: each question does build on each other a) How much would she save? How much would she consume? b) If she wins the lottery during the first year, raising her earnings to $10000 this year, how much would she save, how much would she consume? c) If she now wants to consume twice as much in year 1 as she does in year 2, how much would she save, how much would she consume? d) If she now has no preferences about her consumption, but she wants to save $5000 in year 1 (to buy a new car in year 2), how much would she consume in year 1 and year2?
If mpc = 0.8 and the additional income is P12,000, how much is the additional consumption? How much is the additional savings? show the computations
If you draw the cash flows from any investment, you would have negative cash flows at the beginning, and then you would receive a stream of positive cash flows thereafter. So why do we need the separate concept of a J-curve? In other words, what is the difference between a J-curve and the cash profile of any other investment?
Suppose as a hypothetical scenario that you deposit $400 today into a savings account with a variable interest rate and will collect a payment in one year. True or False: If over the course of the year the interest rate falls, this increases the future value of your investment. True False
