Kinked Demand Curve

  • Kinked Demand - When the demand curve changes angles.
  • If firm A raises their price, the other firms will not follow so consumers will all switch to the competitors. So if firm A raises their price, the demand is
    elastic
    . In the diagram below this would be any price
    higher
    than $25.
  • If firm A cuts their price, other firms will also cut price so they will not gain a lot of extra customers. When they cut the price, the demand is
    inelastic
    . In the diagram below this would be any price
    lower
    than $25.




Practice: Kinked Demand Curve

With a kinked demand curve, if the price is currently at the point of the angle change, then the elasticity is higher:
