Change in Supply Impact on Equilibrium

Table Of Contents




  • Moving along the curve
  • Increase in supply
  • Decrease in supply
  • Equilibrium
  • Equilibrium price
  • Equilibrium quantity


A graph at equilibrium will have quantity supplied equaling quantity demanded. As shown below by the graph:

When there is an Increase in Supply, the supply curve shifts to the right. The result of this shift is an Increase inEquilibrium Quantity and a Decrease in Equilbrium price. As shown by the graph below: By Graph 1

When there is an Decrease in Supply,the supply curve shifts to the left. The result of this shift is a Decrease in Equilibrium Quantity and a Increase in Equilibrium price. as shown by the graph above: Graph 2

Practice


Consider how the following events would change the equilibrium price and quantity in the market specified in the question. To see the answers, highlight the blacked-out text. (Note: you may want to review the Determinants of Supply before taking this quiz)

1. The price of steel significantly decreases. (Automobile market)
Equilibrium price decreases.
Equilibrium supply increases.
