Solution:In India, we define money multiplier as the ratio of the stock of money or Broad Money (M3) to the stock of high powered money or Reserve Money (Mo or Rm). So if money multiplier is K, then K = M3/Mo or M3/Rm.The money multiplier refers to the ratio of the total amount of money that can be created in the economy to the amount of new reserves injected into the banking system. It represents the potential increase in the money supply resulting from an initial injection of funds into the system.
The money multiplier is based on the fractional reserve banking system, in which banks are required to hold only a fraction of their deposits as reserves and can lend out the remaining amount. As loans are repaid, new deposits are created, and the process continues, leading to an expansion of the money supply. The money multiplier is an important concept for understanding the relationship between the monetary base and the money supply in an economy.
When banks receive deposits, they are required to hold a certain percentage of those deposits as reserves (known as the reserve ratio). The remaining amount can be lent out to borrowers in the form of loans, which increases the money supply in the economy.
The amount by which the money supply increases for every unit increase in the monetary base is known as the money multiplier. It is determined by the reserve ratio, as well as other factors such as the willingness of banks to lend and the demand for credit from borrowers.
