In its simplified form, the quantity theory of money says that there is a direct and proportional relationship between the quantity of money in the economy and the price level. The equation is

M*V = P*Q

where M is the total amount of money in circulation, V is the velocity of the money -- how often it passes from one person to another, P is the price level and Q is the value of final expenditures.

An increase in money supply would have no effect on nominal GDP when money velocity (V in the equation) declines. Keynesians argue that this can happen, while classical economists operate on the assumption that money velocity can be taken as a constant.

I wondering for the same that what is the quantity theory of money. I was searching for it on Google and I found your post..It was really helpful.high-density shelves

Explain how changes in the money supply can affect real GDP and the price level. Under what circumstances could an increase in the money supply have no effect on nominal GDP?
