Suppose the velocity of money (V) is constant, Money supply (M) is growing at 5% per year, output (Y) is growing at 2% per year and interest rate (r) is 4%. Using the knowledge of the quantity theory of money and the Fischer effect;
a) Solve for i (nominal interest rate)
b) If the Central Bank increases the money supply by 2 percentage point per year, find the change in nominal interest rate
c) Suppose the growth rate of Y falls to 1% per year, what will happen to inflation? What can the Central Bank do if it wishes to keep inflation constant?
Suppose V is constant, M is growing 5% per year, Y is growing 2% per year, and r = 4.
a)
We first find
Therefore,
b)
It is just the same as the increase in the money growth rate.
Hence,
c)
The central bank does nothing . For the central bank to prevent inflation from rising, it must reduce the money growth rate by point per year.
