15. Suppose that the relationship between inflation rate (π) and unemployment rate (u) is described by the following equation:
πt – πte = (m + z) – αut
where m = 0.05, z = 0.04, and α = 2. In this economy, the authorities keep unemployment rate at 4% forever.
a. If the modified Philips curve describes the relationship between π and u correctly, how should “πte” be specified? Rewrite the equation using this specification. Assume that πt–1 = 1%. Compute πt, πt+1, and πt+2.
b. Do you believe the answer in part (a)? Why or why not?
c. Derive the natural rate of unemployment.

3) Suppose that on January 1, 2019 a bank lends $20,000 to a person. The bank and the individual both agree that the real interest rate charged on the loan should be 10% and the loan is going to be totally paid ($20,000 plus interest), in a one-time payment, on December 31, 2020. Suppose the two parties to this transaction can perfectly foresee what the inflation rate for this period is going to be. Given this information, what is the nominal rate the Bank has to charge on this loan? Assume that the CPI is computed at the beginning of each year.
According to US inflation data:
The historical average CPI for 2019 is - 255.657
The historical average CPI for 2019 is - 258.811
The inflation rate during the period is: (258.811/255.657 -1) *100 = 1.233%
Real Interest Rate = Nominal Interest Rate – Expected Inflation
Nominal Interest Rate = Real Interest Rate+ Expected Inflation
Nominal Interest Rate = 10% + 1.23%
Nominal Interest Rate…
Assume the expected after-tax real interest rate is 1% and that the nominal interest rate is 4% .Suppose that the actual inflation rate turns out to be 4% as well. What is the realized after -tax real interest.?

Suppose the two parties to this transaction can perfectly foresee what the inflation rate for this period is going to be. Given this information, what is the nominal rate the Bank has to charge on this loan? Assume that the CPI is computed at the beginning of each year. Nominal interest rate refers to the interest rate before taking inflation into account. Nominal can also refer to the advertised or stated interest rate on a loan, without taking into account any fees or compounding of interest. Therefore the interest charged by the bank is 10% only with no adjustments of inflation rate over the year. The amount of money charged by the bank as interest in one year equals to ; 20000$× 10/100= 2000$.…arrow_forward3) Suppose that on January 1, 2019 a bank lends $20,000 to a person.

- Your company has been trying to grow since its creation in the year 2000, and the board of directors is dissatisfied that your department’s advertising budget has increased 40% since the year 2000 but that little growth has occurred as a result. What argument might you make in your defense? Select one: a. While the nominal value of the budget has grown 40%, the real value (adjusted for inflation) has dropped sharply, so we have been lucky to even stay in business over these years. b. While the real value of the budget has grown 40%, the output of the national economy (as indicated by the mild growth of the GDP deflator) has been stagnant, so our lack of company growth is no surprise. c. While the nominal value of the budget has increased 40%, the real value has increased even greater than that, so the lack of growth has to be attributable to another department of the company. d.
