00:01
So for this question, basically the answer should be correct.
00:05
So the student is stating correctly.
00:07
So the start was last, firstly, draw the original graph.
00:13
So we have quantity, we have price, we have demand curve, and supply curve.
00:19
So basically, originally we have the equivalent price, t star, and the equivalent quantity q star.
00:27
So now let's look at the change.
00:29
So the first change is the demand for smart watch increase rapidly.
00:34
So the first thing we know that is there is a right ship of demand curve.
00:39
Basically means the increase of demand.
00:45
And at the same time, there are six more firms beginning producing smartwatches.
00:51
So this part is basically saying that the supply is also increased.
00:56
And supply increase basically we mean that.
00:59
The supply curve also shift to the left, or shift to the right, sorry.
01:03
So you'll see a right shift of supply curve at the same time.
01:08
So this is a supply increase.
01:11
So let's look at this equilibrium in this case.
01:15
So we need to find a new equilibrium by finding the crosspoint of the new supply curve and the new demand curve.
01:22
So it is this point here...
