Suppose that some years ago your grandfather has created an account which will provide you with a certain amount of cash over a 20 year period. He arranged such that you will receive your first payment one year from now in the amount of 3000. Also suppose that you will receive 6% net increase every year over the next 20 years. That is, your first payment will be 3000, second will be 3000(1.06), third will be 3000(1.06)2 and so on in terms of constant dollars. Suppose that over the next 20 years, the inflation rate will be 5% per year and the inflation-free interest rate will be 3% per year. a)How much will be your last payment (20th year) in terms of constant dollars? b)How much will be your last payment (20th year) in terms of actual dollars? c)Using constant dollar analysis and the geometric gradient formula, find the present worth of your total earnings over 20 years. d)Using actual dollar analysis and the geometric gradient formula, find the present worth of your total earnings over 20 years
