Frequent-flier games: The problem of employee abuse
研究了企业员工滥用常旅客计划（如绕道或高价购票以积累里程）的问题，发现滥用并不像假设的那么普遍，建议将里程奖励作为对员工差旅辛苦的补偿，同时要求员工不滥用并遵守道德。
Executive Overview Since American Airlines introduced frequent-flier programs in 1981, an estimated twenty-four million people have joined approximately forty programs, earning about 875 billion miles of credit. Most frequent fliers are businesspeople collecting mileage credits while traveling on corporate expense. Employers and other observers assume that many of them pad this perk by arranging unnecessary or circuitous travel on premium fares at less than convenient times. Some corporations have taken steps to minimize or curtail abuse by putting restrictions on employee travel arrangements, or by recapturing the awards for future business trips, the latter resulting in an estimated three to five percent saving on corporate airline travel expenses. However, the corporate confiscation of travel awards often creates employee hostility, especially when some of the mileage credits are earned on non-business trips and activities. U.S. airlines do not allow separate corporate accounts, so neither employer nor employee can easily separate business and non-business mileage accrual. Our investigation indicates that the problem of employee abuse of frequent-flier benefits is not as widespread as assumed. We recommend a policy that some corporations already use: frequent-flier awards accrue to the travel-weary employee as partial compensation for what has become a less than glamorous way to travel. The only conditions are that employees must not abuse this privilege and should conduct themselves in an ethical manner consistent with the best interest of the corporation, when making travel plans. We also predict that corporations eventually will be allowed to join frequent-flier programs directly, earning bonus awards on corporate travel accounts.
