With the end of the Cold War, the U.S. government decided to downsize the military. Along with a pink slip, the government offered ex-military personnel their choice of $8,000 a year for 30 years or an immediate lump-sum payment of $50,000. The lump-sum option was chosen by 92% of enlisted personnel and 51% of officers (Warner and Pleeter, 2001). What is the break-even personal discount rate at which someone would be indifferent between the two options? What can you conclude about the personal discount rates of the enlisted personnel and officers?
