Okay, so we're trying to figure out what the effect of each of the following scenarios will be on the demand of small cars.
00:09
We'll start off with our supply and demand curve.
00:13
We have price per car and quantity of cars.
00:18
So we'll only write down the demand curve because that's what this question will focus on.
00:23
When there's an increase for demand, there will be a right -word shift of the curve.
00:34
When there is a decrease in demand, there will be a leftward shift.
00:54
So when we're trying to figure out which way the curve will, the demand curve will shift, we're looking at things like income increasing or decreasing.
01:04
Is it a normal good or an inferior good? we're also looking at the price of substitute and complementary goods, taste and preferences, future expectations, number of buyers.
01:16
And various other things too.
01:19
So in scenario a, we have small cars becoming more fashionable.
01:27
So in this case, demand will increase because since small cars are being more fashionable, that means that they're more preferred.
01:34
And if they're more preferred, then that means demand for them will increase, and this will lead to a shift of the curve to the right.
01:42
So we have an increase in demand.
01:51
And in scenario b, we have the price of large cars increasing.
01:58
So large cars are a substitute for small cars.
02:03
And this will lead to an increase in demand for small cars.
02:08
Because when the price of one substitute increases, the demand for the other substitute will increase.
02:17
So again, the price of a substitute good if it increases, and the demand, for the other substitute good will increase...
