What is the total amount of increased money supply? What is the total amount of increased monetary base? What is the ratio between increased money supply and increased monetary base? (5 marks) 1+C c. Use the formula m = to calculate the money multiplier. Does it have the same rterd value as the ratio calculated in sub-question b? If not, how would you like to make adjustment so that those two can be matched? (15 marks) 5. Central Bank and Money Supply (30 marks). a. The Central Bank makes open market purchase of 100 million.
