So here we're using the quantity theory of money, which, as you probably know, says that mb is equal to py.
00:06
We know that m is equal to 50 billion.
00:09
We know that nominal gdp, right, be very careful, is one trillion or a thousand billion, right? billion, billion, right? this is nominal gdp, right? y is equal to real gdp.
00:26
So we know that y itself is equal to 500 billion.
00:32
So pretty straightforwardly we conclude here that p is equal to two.
00:36
That's the price level.
00:38
Once we know that p equals to two, we can plug in, right? so we plug in 50 billion times v is equal to a thousand billion.
00:48
This implies that v is equal to 20.
00:51
Right, we just use the equation that we've been given.
00:55
And then what will happen to nominal gdp in the price level next year? if the bank keeps the money supply constant, well, again, let's go back to mv is equal to p y.
01:06
So if the bank of canada is kept keeping this side constant, and we know that this is going to go up by plus 5%, right? why? then price must decline by 5%.
01:22
We should expect 5 % deflation because this equation...
