16. Suppose a country has a money demand function (M) = kY, where k is constant parameter. The money supply grows by 15 percent per year, and the real income grows by 7 percent per year. a. What is the average inflation rate? (3 points) b. How would inflation be different if real income growth is 10 percent? (3 points) c. How do you interpret the parameter k? What is its relationship to the velocity of money? (6 points) d. Suppose, instead of a constant money demand function, the velocity of money in this economy was growing steadily because of financial innovation which is 2 percent.
