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 equal amounts in both periods; that is, he or she would like to set c=c', if possible. However, this consumer is faced with a credit market imperfection in that he or she cannot borrow at all; that is, saving s20. (a) Show the consumer's lifetime budget constraint and indifference curves in a diagram. (b) Calculate his or her optimal current-period and future-period consumption and optimal saving and show this in your diagram. (c) Suppose that everything remains unchanged, except that now t=20 and t'=71. Calculate the effects on current and future consumption and optimal saving and show this in your diagram. (d) Now, suppose alternatively that y=100. Repeat parts (a) to (c) and explain any differences.

Suppose that an oil well is expected to produce 100,000 barrels of oil during its first year of production. However, its subsequent production (yield) is expected to decrease by 10% over the previous years' production. the oil well has a proven reserves of 1,000,000 barrels. a) Suppose that the price of oil is expected to be $60 per barrel for the next several years. What would be the present worth of the anticipated revenue stream at an interest rate of 12% compounded annually over the next seven years? b) Suppose that the price of oil is expected to start at $60 per barrel during the first year, but to increase at the rate of 5% over the previous year's price. What would be the present worth of the anticipated revenue stream at an interest rate of 12% compounded annually over the next seven years? c) Consider part (b) again. After three year's production, you decide to sell the oil well. what would be a fair price? Note:- Do not provide handwritten solution. Maintain accuracy and…
Consider a EITC program that offers a guaranteed income level. Assume a person can receive a maximum EITC benefit of $5,000 when earned income is $0; however, the maximum benefit is reduced at a 40% phase-out rate for each dollar earned beyond $0. What is the break-even point?

A bank agrees a repurchase agreement (Repo) with its prime broker using £30 million of Mortgage Backed Securities as collateral for a period of 50 days. The prime broker levies a haircut of 10 per cent and charges an annual Repo rate of 4.5 per cent. What is the price at which the bank will repurchase the £30 million MBS at the end of 50 days when the Repo rate interest applies only on the sum of money being lent by the prime broker ? Use a 360 day-count.
Consider a two-period living consumer with a utility function, u(c)=sqrt(c). Suppose the real interest rate, R=10% and the utility discount factor, beta=0.95. If the consumer wants to maximize lifetime utility, what will be the growth rate of her consumption from the current to the future period?

the answer to this question is Q3.14=$94.13 but we just need to find how we get that answer for these questions, please help 3.14 (LG 3.4) It is May 1. You have just bought $2000 worth of furniture. You will pay for it in 24 equal monthly payments, starting at the end of May next year. Interest is 6 percent nominal per year, compounded monthly. How much will your payments be?
Suppose that there is a credit market imperfection due to asymmetric information. In the economy, a fraction b of consumers consists of lenders, who each receive an endowment of y units of the consumption good in the current period and 0 units in the future period. A fraction (1-b)a of consumers are good borrowers who each receive an endowment of 0 units in the current period and y units in the future period. Finally, a fraction (1-b)(1-a) of consumers are bad borrowers who receive 0 units of endowment in the current and future periods. Banks cannot distinguish between good and bad borrowers. The government sets G=G' = 0, and each consumer is asked to pay a lump-sum tax of t in the current period and t' in the future period. The government also cannot distinguish between good and bad borrowers but can observe endowments. a. Write down the government's budget constraint, making sure to take account of who is able to pay their taxes and who does not. The government's budget constraint in…
Assume that a consumer's utility over two years is a function of consumption during the two years. Let the consumer's utility function be U(C1, C2) = In C + 3 In C2, where Ci is consumption during the 1st year, and C2 is the consumption during the 2nd year. The consumer's income is Y, during the Ist year and Y, during the 2nd year. Let R denote the annual interest rate (0
Suppose you are moving into a new apartment that you expect to rent for five years. The owner of the apartment offers to provide you with a used refrigerator for free and promises to maintain and repair the refrigerator during the next five years. You also have the option of buying a new energy- efficient refrigerator (with a five-year free maintenance agreement) for $600. The new refrigerator will reduce your electric bill by $150 per year and will have a market value of $50 after five years. The interest rate is 12%. Use the preceding information to calculate the present value of the cost saving and resale value of the refrigerator. Then decide if the investment is worthwhile, given the present value of the cost of the refrigerator. At this interest rate, the present value of cost saving and resale value of the new refrigerator is about present value of the cost of the refrigerator. Thus, you should choose the refrigerator. which is than the
The Philippine debt as of today amounts to 12 trillion. This balloons with an interest rate of 0.16% yearly. Suppose the government requires every earning individual to pay the debt by 2030, how much each of us would need to pay monthly (annual payment amortized in 12 equal payments), assuming that inflation is 3%, the interest rate is 5.6%compounded daily, and we will start the payment by the end of 2022? The Philippines is estimated to have 110million people, with the work force of around 20%.
