Okay, so here we have a monopolist, and we're asked, i think, first to show the equilibrium.
00:14
Profit maximizing output for the monopolist is where marginal revenue equals marginal cost.
00:19
So i think they want to call that q1, p1 maybe.
00:26
And under this situation, the consumer surplus is the area between the price and the demand curve.
00:36
So it's the red hash.
00:38
And now we're asked, what if they can perfectly price discriminate, i .e.
00:44
Charge each person the willingness to pay? pay.
00:46
The monopolist will continue to do that up until the point where that last unit sold is equal to marginal cost.
00:57
So the new equilibrium will be where marginal cost is equal to demand or average revenue...
