Answer:

(a) Money supply decreases by $15 million; economy's reserves decreases by $3 million

(b) False

(c) False

Explanation:

(a) Required reserve ratio = 20 percent

Government bonds sold by Fed = $3 million

Money multiplier = 1 ÷ Required reserve ratio

= 1 ÷ 0.20

= 5

Money supply decreases by:

= Money multiplier × Decline in reserves

= 5 × $3 million

= $15 million

Therefore, the economy's reserve decreases by:

= Change in money supply × Required reserve ratio

= $15 million × 0.20

= $3 million.

(b) FALSE.

Now, if central bank reduces the reserve ratio but banks maintain excess reserves,

then the money multiplier:

= 1 ÷ (r+e)

= 1 ÷ (0.15 + 0.05)

= 5

Because money multiplier remains the same.

(c) False.

Since money multiplier remains constant, the overall change in money supply will not increase.
