What to Focus On

  • Utility is the want-satisfying capacity of a commodity and is purely subjective.
  • Total Utility (TU) is the total satisfaction from consuming all units of a good.
  • Marginal Utility (MU) = TUₙ − TUₙ₋₁ is the extra satisfaction from one additional unit.

  • Cardinal utility analysis assumes utility can be quantified numerically in 'utils'.
  • A rational consumer purchases a good until MU equals the price of the good.
  • Since MU declines, consumers are willing to pay less for additional units — demand curve slopes downward.

  • Ordinal utility analysis ranks preferences without numerically measuring utility.
  • An indifference curve shows all bundles giving equal satisfaction to the consumer.
  • MRS = |ΔY/ΔX| — rate at which consumer substitutes one good for another keeping utility constant.

Common Mistakes to Avoid

Higher utility means higher usefulness or practicality of a commodity

Total Utility always increases as you consume more units of a good

An indifference curve can be upward sloping or horizontal

Memory Tips

Utility — want-satisfying capacity of a commodity

Law of Diminishing Marginal Utility — each additional unit gives less satisfaction

Total Utility vs Marginal Utility relationship

MU formula: MUn = TUn − TUn-1
