Two former Northwestern University students worked in an
investment bank at a salary of $60,000 each for 2 years after
they graduated. Together they saved $50,000. After 2 years,
they decided to quit their jobs and start a business designing
Web sites. They used the $50,000 to buy computer equipment,
desks, and chairs. For the next 2 years, they took in $40,000 in
revenue each year, paid themselves $10,000 annually each,
and rented an office for $18,000 per year. Prior to the investment,
their $50,000 was in bonds earning interest at a rate of
10 percent. Are they now earning economic profits? Explain
your answer.
