Key Topics to Revise

1

1. Utility and Cardinal Utility Analysis

  • Utility is the want-satisfying capacity of a commodity - it's subjective and varies between individuals
  • Total Utility (TU) is the total satisfaction from consuming a given quantity of a commodity
  • Marginal Utility (MU) is the change in total utility from consuming one additional unit
2

2. Ordinal Utility Analysis and Indifference Curves

  • Ordinal utility analysis ranks preferences without measuring utility in numbers
  • Indifference curve shows combinations of goods giving equal satisfaction
  • Marginal Rate of Substitution (MRS) is the rate at which a consumer substitutes one good for another
3

3. Budget Set and Budget Line

  • Budget set contains all bundles a consumer can afford with given income and prices
  • Budget line shows bundles that cost exactly equal to consumer's income
  • Budget constraint: p₁x₁ + p₂x₂ ≤ M (where M = income, p₁, p₂ = prices, x₁, x₂ = quantities)
4

4. Consumer's Optimal Choice

  • Rational consumer chooses the bundle that gives maximum satisfaction within budget
  • Optimal choice occurs where budget line is tangent to highest possible indifference curve
  • At optimum: MRS = price ratio (p₁/p₂)
