a) Are ordinal functions
b) Are cardinal functions
c) Are pointless because utility cannot be measured

Answer
a
Exercise \(\PageIndex{8}\)
Which best summarizes the basic idea of consumer choice theory?
a) Consumers optimize by choosing the healthiest but lowest cost bundle of food items
b) Consumers have preferences that are complete, reflexive, transitive, monotonic, and convex
c) Consumers select the bundle of goods of services they like best from all bundles in their budget set

Answer
c
Exercise \(\PageIndex{9}\)

a) Could be used to value characteristics that are not traded on the market
b) Explain price of a purchased good in terms of characteristics that consumers perceive to be important
c) Have theoretical roots in Lancaster’s characteristics model
d) All of the above
e) Choices a and c only
Answer
c
Exercise \(\PageIndex{10}\)
Consumer sovereignty
a) Means that consumers are vulnerable and so sovereign states need to be especially vigilant when implementing and enforcing consumer protection laws
b) Means that economic activity is ultimately directed by consumers through their purchase decisions
c) Means that economic activity is directed by central planners who are elected by sovereign consumers

Answer
b
Exercise \(\PageIndex{11}\)
An ordinal utility function differs from a cardinal utility function in that
a) Cardinal utility always satisfies the cardinal axioms of preferences (complete, reflexive, etc.) while ordinal utility might not.
b) Ordinal utility is usually used for ordinary products, while cardinal utility is used for the luxury goods
c) With an ordinal utility function we are interested primarily in how the function ranks bundles
d) Ordinal utility is a function of prices. Cardinal utility is a function of quantities
Answer
c
