Effects of a Change in Demand or Supply on the Equilibrium Position

Effects of a Change in Demand or Supply on the Equilibrium Position

  • Within a market, the position of equilibrium could change due to:
    • A change in demand, whereby the demand curve shifts to the right or left
    • A change in supply, whereby the supply curve shifts to the right or left
    • A more or less simultaneous change in demand and supply

 

  • When looking at these effects, it is important to be mindful of the time scale
  • Markets, especially on the supply side, cannot adjust quickly
  • On the demand side, however, epidemics can have a rapid effect on the equilibrium price and quantity
  • The usual assumption made is that all other market factors remain unchanged.
