2010, Form B, Question 1 · 10 points
Toll bridge pricing under different goals
Use a cost and revenue diagram for a bridge to find the output and toll for a profit-maximizing owner and an allocatively efficient public owner, judge profit and elasticity at break-even, predict what a ferry competitor does, and decide whether a second bridge makes sense.
This exam had three free-response questions with 10 minutes of planning and 50 minutes of writing, and the directions suggested spending about half the time on Question 1 and splitting the rest evenly between Questions 2 and 3. The current exam has 3 free-response questions in 60 minutes. The skills these questions practice still count.
