A small private university normally charges the same price -$200-per credit-hour for all
courses and for all students. While the university is pretty near capacity in the fall and
spring, it finds that its classrooms are only about 60 percent occupied during the
summer session. A student of operations management (who has recently read this
chapter) wonders if yield management might be useful to both the university and its
students alike. This student, with help from some economics majors, estimates a
demand curve for summer course enrollment. Points on this demand curve include 9000
credit-hours at the current rate of $200, 12,000 credit hours at $180, 15,000 credit-hours
at $160, and 18,000 credit-hours at $140. Based on this demand curve, what price point
would best serve the university, if its objective is the greatest revenue for the summer
session?
