CS and PS with Subsidies



  • Consumer surplus is above the consumer's price ($48) but below the demand which is
    16 * (80 - 48) * 1/2 = $256
  • Producer surplus is below the producer's price ($52) but above the supply which is
    16 * (52 - 20) * 1/2 = $256
  • Cost to government is the subsidy multiplied by the new quantity which is
    $4 * 16 = $64
  • DWL is the triangle between the old equilibrium quantity and the new quantity which is
    (16 - 15) * (52 - 48) * 1/2 = $2
