Here we can see an example of the supply curve being shifted to the right, which is illustrative of the cost of production going down.
00:12
So we move from point a to point b to point c as our respective equilibiums, and during that time, what's happening to the price? well, the price you can see is falling, and the quantity you can see is increasing.
00:26
Okay, so now what about the consumer surplus and the producer surplus? well, at first, the consumer surplus is to the left of the demand curve, to the right of the vertical axis, and it's everything above the price line at point a.
00:41
As we move down, you can see that this consumer surplus continues to grow, and it is now everything above the line from point b, and then finally everything from the line at point c.
00:54
Okay.
00:56
So what about the producer surplus? well, the producer surplus originally is also bounded by a.
01:04
Let's get rid of the consumer surpluses for a second.
01:10
So your producer surplus would be everything below line a to the right of the vertical axis and to the left of the initial supply curve.
01:21
Then what happens? then it grows.
01:24
It grows to be everything below line b.
01:30
And again to the right of the vertical axis and to the left of the second supply curve.
01:36
And then finally, it's everything below line c...
