So here we are talking about the quantity theory of money, right? and there are...
00:06
We need to invoke this quantity equation.
00:08
The equation, sometimes called the equation of exchange, is the very famous mv is equal to py, right? so m is equal to money, v is equal to velocity of money, how fast that money moves.
00:25
So the idea here is this is money used, right? it's the amount of money times how often it's used.
00:32
So if you have a dollar bill and it's used three times a year, you can calculate that three dollars gets spent.
00:38
We also have p, which is prices, and y, which is real gdp.
00:45
So this is also money spent, right? this is why this equation is supposed to be true.
00:52
Money used is equal to money spent...
