(i) Define the three types of price discrimination, clearly stating the different
information requires of each type of discrimination.
(ii) Find a real-world example of second-degree price discrimination. Describe the
important aspects of your example in detail and analyze it using economic theory. In
particular, how does the producer discriminate between the types of consumers – that
is, how does the producer get the consumers to reveal their private information (their
type)?
(iii) What are the welfare implications of the discrimination in your example? Is there
a potential role for government to regulate the practice?
