Question

How are the equilibrium price and quantity affected when both demand and supply curves shift in the same direction?

Answer 1

 both demand and supply curves shift in the same direction

Cases	Equilibrium Price	Equilibrium Quantity	Figure
1) Increase in Dd = Increase in supply	Unchanged	Increases
2) Increase in Dd more than increase SS	Increases	Increases
3) Increase in Dd less than increase in SS	Falls	Increases
4) Decrease in Dd = decrease in SS	Unchanged	Falls
5) Decrease in Dd more than decrease in SS	Falls	Falls
6) Decrease in Dd less than decrease in SS	Increases	Falls
