All right, we're doing problem number 26, which is asking what causes a movement along the demand curve.
00:05
What causes a movement along the supply curve? so let's draw it.
00:11
Here's the demand curve.
00:14
And what's going to cause you to go from here to here? well, shift of the supply curve.
00:22
These are really poorly drawn supply curves.
00:25
A shift of a supply curve from here to here is going to cause a movement along the demand curve.
00:31
Demand itself is not changing.
00:34
Demand this whole curve isn't changing, but the quantity demanded is changing, and that's what a movement along the curve means.
00:42
It's a change in the quantity demand for quantity supplied.
00:45
And the only way that's going to be changing is due to the intersection changing with the supply curve...
