Okay, so this question basically asks about consumer surplus.
00:05
And for consumer surplus, let's draw a graph here.
00:10
The demand curve of consumer should be downward sloping.
00:15
This is the demand curve.
00:16
And we have a specific market price p star here.
00:20
So the consumer surplus basically matters the price.
00:24
The consumer is willing to accept and the price the consumer actually pays.
00:29
So basically is this upper triangle here.
00:35
So the first thing you need to know is there will never be negative consumer surplus.
00:41
Consumer surplus can never be negative.
00:43
You think about what if the consumer surplus is negative.
00:47
It means that the price the consumer actually pays is much higher compared with the price the consumer is willing to pay.
00:58
So if the consumer doesn't want to make that high payment, why there's need for him to buy the good.
01:06
So there will be never negative consumer surplus...
