So here we know a lot of things about the current competitive environment.
00:04
The price is 25.
00:06
The quantity is equal to 10 ,000.
00:09
The average total cost is equal to 28.
00:13
The marginal cost is equal to 20.
00:16
The average variable cost is equal to 20.
00:19
What do we know here, right? a, the firm is currently at minimum abc.
00:29
Well, what do we think? well, let's draw the answer, or how you should think about the answer is to draw some cost curves, right? here's abc.
00:42
Abc is u -shaped because of diminishing marginal returns, right? or diminishing marginal returns or something like that.
00:56
Economies of scale, at size, etc., etc.
01:00
So this minimum average variable cost intersects, right, the marginal cost.
01:08
The marginal cost always goes through the minimum of the average variable cost, right? that is the definition of where those two have to intersect.
01:18
The idea here is that average variable cost is being dragged down because mc is below.
01:26
And up here, average cost is increasing because we have mc above...
