So before i answer the questions, let's just draw a monopolist.
00:05
The monopoly picture that hopefully you're familiar with looks like this.
00:10
Demand, marginal cost, marginal revenue.
00:16
You set marginal revenue equals to marginal cost.
00:20
That defines your price and your quantity, right? and that leaves you a monopolist's profit, a difference between price and marginal cost.
00:29
Great.
00:30
So a marginal revenue is, marginal revenue is lower is located lower than demand.
00:47
And the reason it's lower than demand is because when you sell another unit, you get the price, which is the demand curve, but you lose on the units you've previously sold.
00:56
Because each time you sell more, you move down the demand curve.
01:00
And as you move down the demand curve, and as you move down the demand curve selling more, you're getting more sales, but you're lowering the price.
01:05
Marginal revenue captures those mixed effects.
01:08
Compared to a competitive outcome, which would be here, right, b, monopolist sells lower quantity than competitive at higher price.
01:27
The whole point of a monopolist is to create scarcity.
01:30
I want to make profits.
01:31
I make profits by making my good expensive...
