While movements up and down along the demand curve reflect changes in quantity demanded, many other factors can cause shifts in the demand curve.
That is, they can increase demand – a demand curve shift to the right.
Or, decrease demand – a demand curve shift to the left.
Factors that can cause shifts in the demand curve include:
- Changes in income.
- Changes in technology.
- Changes in preferences.
- Changes in population.
- Changes in the price of substitutes and compliments.
