So here we have a monopoly, right? and we've got a very interesting diagram, quantity and price.
00:06
It's a market, right? we have two curves, right? several curves.
00:10
Oh, we don't know the curves.
00:12
So my first curve is this is a.
00:14
And this is demand, right? the second curve here is marginal revenue, right? this is curve b.
00:21
And we can tell it's the marginal revenue because it has the same intercept, but two times the slope.
00:30
That's what the definition of what marginal revenue looks like.
00:35
We have a marginal cost curve, which is curve c, right? and then it looks like we have an average total cost curve that looks something like this.
00:47
Average total cost, which is curve d.
00:50
And the idea is that average total cost is always going to be u -shaped, right? so the goal is to equate these two, right? the monopolist wants to maximize profit.
01:03
And the monopolist maximizes profit by setting marginal revenue equals to marginal cost.
01:11
So the monopolist quantity here would be, looks like q3, right? it's hard to tell, but i'm pretty sure it's q3.
01:27
Yes, definitely q3...
