Question
**Challenge Problem:** The chapter mentions that an open market operation by the Fed can increase or decrease the quantity of deposits in banks and therefore the money supply.

The change in the money supply from a Fed open market operation is given by the following equation:

\[ \text{Change in money supply} = \text{Change in reserves} \times \frac{1}{(RR + ER)} \]

where:

- **RR** = the percentage of deposits that banks are required to keep as reserves
- **ER** = the percentage of deposits that banks voluntarily hold as excess reserves
- \(\frac{1}{(RR + ER)}\) = the "money multiplier"

Suppose the Fed decides to sell $16 billion in Treasury bonds. Assume that the reserve requirement is 10 percent, banks hold 3 percent in excess reserves, and the public holds no cash.

This action by the Fed causes the money supply to ▼ by $--- billion. *(Round your response to two decimal places.)*

Expert Solution
Step 1

The formulae for the money multiplier(m) is:

M=R×1RR+ER

Where  is the change in the supply of money(M)

is the change in the reserve(R)

RR is the required-reserve and ER is the excess-reserve.
