What are shifts in supply?
While movements up and down along the supply curve reflect changes in quantity supplied, many other factors can cause shifts in the supply curve.
That is, they can increase supply – a supply curve shift to the right.
Or, decrease supply – a supply curve shift to the left.
Factors that can cause shifts in the supply curve include:
- Changes in the number of producers or sellers
- Changes in technology.
- Changes in the price of inputs.
