##### Exercise $$\PageIndex{4}$$
1. In Lancaster’s model of the consumer, utility is a function of

a) Leisure time

b) Household produced goods and services

c) Product characteristics

d) Purchased goods

c

##### Exercise $$\PageIndex{5}$$
1. In the Neoclassical model of the consumer, utility is a function of

b) Household produced goods and services

c) Product characteristics

d) Purchased goods

d

##### Exercise $$\PageIndex{6}$$
1. Which best describes a hedonic pricing model?

a) The full time income constraint from Becker’s model

b) Product price is a function of product characteristics

c) Product price is a function of quantity placed on the market

d) All of the above

b

##### Exercise $$\PageIndex{7}$$
1. In consumer theory, the direct utility functions we examined in class

a) Are ordinal functions

b) Are cardinal functions

c) Are pointless because utility cannot be measured

d) Are applicable in Becker’s model but are not applicable in Lancaster’s model

a

##### Exercise $$\PageIndex{8}$$
1. 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

d) Consumers minimize spending subject to meeting their minimum daily caloric needs

c

##### Exercise $$\PageIndex{9}$$
1. Hedonic pricing models

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

c

##### Exercise $$\PageIndex{10}$$
1. 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

d) Was first introduced by the Magna Carta, which placed limits on the power of the reigning sovereign

b

##### Exercise $$\PageIndex{11}$$
1. 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

c
