Pay Equality and Industrial Politics
探讨薪酬压缩（即缩小工资差距）对员工合作行为的影响，发现当员工收入基于相对比较时，适度的薪酬压缩能减少不合作行为，提高企业效率。
Personnel managers often argue that equitable pay treatment manifested as wage compression is useful because it reduces disharmony among workers. But it is far from obvious that a compressed salary structure is morale improving since better workers may feel disenchanted by this scheme. However, when workers' rewards are based on relative comparisons, salary compression reduces uncooperative behavior that is detrimental to the firm. Relative comparisons imply that some reference group must be selected. The major result is that, within the relevant groups, some wage compression is efficient.
