The Athenian Theatre sells play 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.
