Question 11.
00:03
Assume that the reserve requirement is 20%.
00:07
And the bank does not hold any excess reserves and the public does not hold any cash.
00:15
So the fed decides that it wants to expand the money supply by $40 million.
00:22
So if the fed is using open market operations, will it buy or sell bonds? so it will buy bonds because by buying bonds, it inject money into the economy.
00:40
So buy bonds here.
00:43
Okay, b, what quantity of bonds does the fed need to buy or sell to accomplish this goal? explain your reasoning.
00:55
So we know that the reserve ratio is 20%, right? so we can see, so we can calculate the money multiplier, which is 1 divided by 20%, that is 5.
01:08
So the money multiplier is 5.
01:12
So we can calculate that it needs to buy a certain amount of bonds, which means it needs to inject this certain number of money into the economy to make this multiplier worse.
01:30
And then in the end it will have $40 million of money supply...
