How do you identify a new equilibrium?

Identify the new equilibrium and then compare the original equilibrium price and quantity to the new equilibrium price and quantity. Let’s consider one example that involves a shift in supply and one that involves a shift in demand. Then we will consider an example where both supply and demand shift.

Does equilibrium price change if demand or supply curve shifts?

Unless the demand or supply curve shifts, there will be no tendency for price to change. The equilibrium price in any market is the price at which quantity demanded equals quantity supplied. The equilibrium price in the market for coffee is thus $6 per pound. The equilibrium quantity is the quantity demanded and supplied at the equilibrium price.

Can equilibrium price and quantity change in a graph?

Of course, when modeling changes in a graph it is possible to see changes in both equilibrium price and quantity when shifting both demand and supply (depending on how much each curve shifts). In the interactive graph below, move both demand and supply in different directions.
