PROBLEMS AND PROJECTS 1. Tammy is a great believer in adaptive expectations. Last year, when the inflation rate was 10 percent she bought a new car with a loan that carried a nominal interest rate of 13 percent. Unfortunately, at least for her, this year's inflation rate is only 4 percent. For Tammy, calculate the following. (Hint: Remember the real interest rate is the nominal interest rate minus the inflation rate.) the rate of inflation she expected b. the real interest rate she expected to pay d. c. the real interest rate she actually paid this year . Has the fall in the inflation rate made her happy or unhappy (at least with respect to the interest rate she is paying on her car)
