Suppose that permanent income is calculated as the average of income over the past five years – that is YP = (Y + Y-1 + Y-2 + Y-3 + Y-4 Suppose further that consumption is given by C = 0.9YP a. If you have earned $20000 per year for the past 10 years. What is your permanent income? b. Suppose that next year (period t + 1) you earn $30000. What is your new YP? c. What is your consumption this year and next year? d. What is your short run MPC and long run MPC? e. Assuming you continue to earn $30000 starting in period t + 1, graph the value of your permanent income in each period using the initial YP equation provided above.

A2) Economics Assuming that the government intends to adopt a ride-sharing scheme to solve the problem of rush hour traffic congestion, the ride-sharing scheme is therefore evaluated. Known: B0 = 0, Bt = 60, t = 1, 2,… (for a perpetual gain); C0 = 1,000, Ct = 0, t = 1, 2,…. Among them, t represents the year, and Bi and Ci are divided into the benefit and cost of the i-th year. Assuming that inflation and government taxation are not considered, if the discount rate is 5%, try to use the present value criterion, the internal rate of return and the profit-to-price ratio method to evaluate whether this multiplication plan is feasible?

Assume that Andrew Marcus is 25 years old and expects to live until the age of 75. (a) If he wins €20 million in cash (after taxes) in the lottery and retires, how much will he consume each year if he wants to have constant consumption and use up all his wealth by the time he dies? Assume the real interest rate is zero. (75 words max) (b) If his total income in the year he wins the lottery is his lottery winnings, what will his average propensity to consume be for that year? (75 words max) (c) If he has no other earnings in later years but continues his constant consumption, what will his average propensity to consume be for those later years? (75 words max) (d) What is Andrew's "permanent income" in the year he wins the lottery? What is his "transitory income"? (75 words max)

Economy 1. Pamela worked as an auditor earning $60,000 per annum. She decided to open her own consultancy business. For her business, she rents an office where she pays $2,000 per annum. Further, her utility expenses are $300 per annum and she hired a part-time secretary to whom she pays $25,000 per annum. To start her business, she borrowed $40,000 from her savings, where she was earning an interest of $500 per annum. In her first year, her business earned a revenue of $300,000. Based on this information, calculate the following: a. Total implicit costs per annum b.Total explicit costs per annum c.Total accounting costs and accounting profit for that year d.Total economic costs and economic profit for that year

Suppose that you are considering whether to enroll in a summer computer-training program that costs $3,600. If you take the program, you will have to give up $1,800 of earnings from your summer job. You figure that the program will increase your earnings by $600 per year for each of the next 10 years. Beyond that, it is not expected to affect your earnings. Suppose the interest rate is 10% Use the preceding information to calculate the present value of the wage increase resulting from the training program. Then decide whether the investment is worthwhile, given the present value of the cost of the training program. At this interest rate, the present value of the increase in wages is about the training. Thus, from a strictly monetary viewpoint, you than the present value of the total cost of , which is participate in the training program.
