  • Suppose we have the following price and quantity values for the demand of calling minutes in cellular phones:

    P1 = 10 cents, Q1 = 5 million minutes, P2 = 11 cents, and Q2 = 4.5 million minutes.

  • Plugging theses numbers into the formula gives us:

    elasticity=- 0.105 ÷ 0.095=- 1.105

  • While the quick and dirty elasticity indicates exactly unit elastic demand (1 on the nose), the midpoint formula indicates relatively elasticity demand (1.105).
