Adina, age 32, is a married architect with one child. Her salary has reached a plateau at $85,000 a year. She believes that if she pursues an MBA degree full-time, she would move into a managerial position and her salary would rise by $60,000 a year. Adina wants to maintain her current lifestyle, which already generates substantial yearly cash savings and accumulate the capital to leave to her son. Her MBA course would take two years to complete and cost $52,000 a year. Because she plans to pay for the MBA out of existing savings and would be spending the money to qualify for a new position, she would not be eligible for any tax benefits. Assume that Adina pays one-third of her salary in taxes and her tax bracket will remain unchanged after the raise, that she can earn 6 percent after taxes on investments with a similar risk to her job, and that she plans to retire at age 65. Furthermore, assume that all salary and schooling payments are made in a lump sum at the beginning of each year. What is her rate of return on this investment? Should she pursue an MBA? If so, what will be the value of her human capital, assuming a calculation that incorporates salary forgone and her extra salary from obtaining her MBA upon graduation?
