Suppose Dublin Electronics charges regular customers $90 for a Blu-ray player but
allows senior citizens to purchase the same item for $75. Is this likely to be a successful
price discriminating strategy?
A) Yes, firms price discriminate to maximize profits.
B) No, price discrimination will not be effective because the store cannot prevent senior
citizens from buying large quantities of Blu-ray players and reselling them for a profit.
C) Yes, because senior citizens are likely to have a more elastic demand and therefore
will be willing to pay a lower price compared to regular customers.
D) No, because there are many different brands of Blu-ray players and consumers will
shop around.
The Athenian Theatre sells tickets for the same play at different prices: a lower price to
those who opt for the seats at the back of the theatre and a higher price for those who
purchase seats in the front, around the stage. Which of the following statements is true?
A) This is an example of product differentiation but not price discrimination.
B) The theatre practices first-degree price discrimination by setting prices based on
willingness to pay.
C) Since the cost of producing the play does not change with the seating configuration,
this is evidence of price discrimination based on market segmentation.
D) Charging two different prices is an effective way to avoid an excess demand for play
tickets; the higher price lowers quantity demanded to some extent.
