Illustrate the complex cases when both supply

Question

Illustrate the complex cases when both supply and demand shift?

Answer 1

If supply increases and demand decreases, price declines, but new equilibrium quantity depends on relative sizes of shifts in demand and supply. If supply decreases and price rises, a demand increase, but new equilibrium quantity depends again on relative sizes of shifts in demand and supply. If supply and demand change in the same direction (both increase or both decrease), the change in equilibrium quantity will be in the direction of the shift but the change in equilibrium price now depends on the relative shifts in demand or supply.
