Q

Four assumptions about consumer preferences

A
  1. completeness and rankability
    - consumers compare and rank bundles of goods
  2. For most goods, more is better than less
  3. Transitivity
    - imposes consistency on rankings
  4. diminishing marginal utility

Q

Characteristics of indifference curves (4)

A
  1. They can be drawn (completeness and rankability)
  2. curves farther from the origin represent higher utility (more is better than less)
  3. Curves never cross (transitivity)
  4. convex to the origin (diminshing marginal utility)`
