As the chinese clothing industry expands and increases exports and begins lowering the world price, it's going to have very similar but slightly different effects for an importing or an exporting country.
00:15
So for an importing country, like say the united states, let's see what happens to consumer surplus, producer surplus, and total surplus.
00:24
Well, if you imagine that the world price was at the dotted green line, you would have consumer.
00:32
Surplus being everything above that dotted line below the demand curve, including this triangle in here, right? and then producer surplus would be everything below the dotted line and to the left of the supply curve.
00:52
Okay.
00:52
Now, once we actually move down to the solid green line, the new world price, the consumer surplus has now expanded to include everything above the solid green line and below to the left of, that is, the demand curve.
01:13
The producer surplus, meanwhile, has shrunk.
01:19
So most of what happened there was what was previously producer surplus just became consumer surplus, right? but there's also been an addition of a new area.
01:31
What is that? well, it's essentially this right here, that trapezoid, if you will, right? that is the addition to total surplus.
01:43
So what's happened to consumer surplus? well, that's gone up.
01:46
Producer surplus has gone down, but total surplus has increased.
01:51
In other words, consumer surplus increased more than producer surplus decreased.
01:57
All right.
01:58
Now, what about an exporting country? all right.
02:01
So here, let's say, again, the world price was formerly at the dotted green line, and it's going to fall to the solid green line.
02:10
So let's look at the before and after.
02:13
For the before, if it's at the dotted green line, you're looking at a consumer surplus in this small triangle...
