So here we know a couple things, right? we know that y is an input into z.
00:09
And we know that z is a substitute, right, for x.
00:19
And now we know that the price of y is going to go up.
00:23
So the price of y goes up.
00:26
Well, what's going to happen in the market for z and the market for x.
00:34
Let me draw the market for z, right? this is z, the price of z.
00:39
We have the market for x, and we're going to have the price of x, demand and supply, oh, sorry, a supply, supply, and demand.
00:52
And now the input shock, right? so the price of y is going up.
00:56
That increases the cost of producing z, right? so the supply of z is going to go up, right? y is needed for z.
01:07
And so when y gets more expensive, producing z gets more expensive, which means that firms need a higher price to produce same z...
