Question
In the U.S., currency in circulation (C) is $1.2 trillion and the monetary base (B) is $3.7 trillion. Assume the reserve-deposit ratio (rr) and the currency-deposit ratio (cr) are both 0.25.
- What is the size of bank reserves (R)? What is the money multiplier? What is the money supply? What is the velocity of money if nominal GDP is $17 trillion?
- If the FOMC increases bank reserves (R) by $0.5 trillion and banks choose to hold all the additional reserves rather than loan them out, what is the new money supply? What is the new money supply if instead banks loan out 50% of the additional new reserves and households deposit all the additional loans?
- Assume that the velocity of money is constant and real GDP is growing at 1%. Use the numbers in part (a) to answer the next question. If the Fed wishes to keep the price level constant, how much (in dollars) do they need to increase the money supply?
