Explanation of Solution

Quantity theory of money is called theory of inflation. The equation can be rewritten as

  %ΔM+%ΔV=%ΔP+%ΔY

Inflation is %ΔM+%ΔV%ΔY=%ΔP=π ,

As velocity is zero or constant, then,

  %ΔM%ΔY=%ΔP=π

In short-run, there is no correlation between output and money growth, as increase in money growth rate takes time (time lag) to increase the productivity of an economy.

In long-run, there is a strong correlation between output and money growth. As money supply increases, productivity of output in long-run increases. It has been noted that, countries with high money growth usually have high-inflation rates.

So, inflation is always and everywhere a monetary phenomenon is accurate in long-run but not accurate in short-run.
