So here we are talking about monopoly, right? and the goal of the monopoly is to maximize profit.
00:07
And profit is equal to revenue minus costs, right? so here i would construct profit directly.
00:19
But we have a very special condition here, right? we can price discriminate.
00:33
So when the monopolist can price discriminate, we're in a very different world than the normal monopoly situation.
00:41
In the normal monopoly situation, you don't want to produce too much because you drive the price down.
00:46
But here we don't drive the price down.
00:49
So let's think about this table.
00:51
We have quantity of 0, 1, 2, 3, 4, 5.
00:55
We have total cost of 250, 260, 290, 350, 480, and 700.
01:11
I'm going to construct marginal cost.
01:14
So the marginal cost for the first unit is 10, then 30, then 60, then 130, then 220...
