Which of the following is not true regarding the outcome of a consumer's optimization process ?

Correct answer: E. The consumer is indifferent between any two points on his budget constraint

  • A. The marginal utility per dollar spent on each good is the same
  • B. The marginal rate of substitution between goods is equal to the ratio of the prices between goods
  • C. The consumer's indifference curve is tangent to his budget constraint
  • D. The consumer has reached his highest indifference curve subject to his budget constraint
  • E. The consumer is indifferent between any two points on his budget constraint

Explanation

Points on the same indifference curve provide equal utility, but different points on a budget line generally lie on different indifference curves. The consumer is therefore not indifferent between any two points on the budget constraint.
