1. There are several tools that the Fed uses to implement monetary policy. Of the three mentioned here the Fed primarily uses open market operations to conduct nation's monetary policy while central banks in developing countries rely primarily on reserve ratios. I will answer both A and B together in the following.

i. Reserve Requirements: Each commercial bank is required to keep a certain portion of all its demand deposits in form of cash or cash equivalent at the end of business each day. The reserve requirement is a primary determinant of the money multiplier. In the absence of currency drain if the required reserve ratio is R%, that is if banks are required to keep R% of total deposits as reserve then the money multiplier is given by

Money Multiplier = 1/R.

The Fed can alter the reserve requirement and thus change the money multiplier. Suppose initially the reserve ratio is 20% then the money multiplier is 1/20% = 5. If the Fed introduces \$100 in the system then the net change in money supply is \$500. Now if the Fed also reduces the reserve ratio to 10% then the multiplier becomes 10 and an introduction of \$100 in the system increases money supply by \$1000. Thus the Fed can lower the reserve ratio to increase money supply.

ii. Discount Rate: Discount rate is the rate at which the Fed lends money to commercial banks to meet overnight reserve requirements. The discount rate also helps determine the Federal Funds Rate, the rate at which commercial banks lend to other commercial banks to meet overnight reserve requirements, and the Federal Funds Rate is the main short-term rate that the market follows. If the Fed wants to increase money supply it can lower the Discount Rate, which in turn will lower the Federal Funds Rate, and this will propagate down to the ...
