So here we have a monopoly, right? and i'm going to reproduce this diagram between quantity and price.
00:07
We have a downward sloping demand curve.
00:10
We have a downward sloping marginal revenue curve.
00:14
We have an upward sloping marginal cost curve.
00:17
And i have to draw this very, very carefully.
00:20
A average total cost curve that looks something like this.
00:24
I think i did okay there.
00:26
So part a, right? what is part a? what is fair price? fair price for a monopoly is often defined as price is equal to average total cost, right? you can think of this as sort of a no excess profit condition.
00:43
That the regulator understands that the monopoly is a unique industry and says, look, you're in a unique industry, but we're only going to let you cover the cost of capital.
00:52
We're not going to let you make any profit.
00:54
You're going to have the exact same margins as a competitive firm...
