Arnold Marion, a first-year economics student at Fazer College, was given an
assignment to find an example of price discrimination and present it to his class. When
asked for his example Arnold said "I went to a Milwaukee Brewers baseball game with
my cousin last week. We paid $25 each for our seats in left field. My aunt and uncle
paid $50 each for their tickets; they sat five rows behind the first base dugout. This is an
example of price discrimination since we paid different prices for the same product, and
the differences were not due to differences in costs." How would Arnold's economics
instructor assess Arnold's example?
A) He would agree with Arnold that he had found an example of price discrimination,
but would add that arbitrage would occur if ticket scalpers sold Brewers tickets for
more than the prices Arnold and his uncle paid.
B) He would disagree with Arnold's example because the $25 seats and the $50 seats
were not the same products.
C) He would agree with Arnold that he had found an example of price discrimination
and would explain that the elasticity of demand for Brewers tickets is different for
Arnold and his uncle.
D) He would disagree with Arnold's example because there were differences in
transactions costs for the $50 tickets and the $25 tickets.

peaches, holding all other factors constant.
