Collective Bargaining and Staff Salaries in American Colleges and Universities
研究利用1997-98年调查数据，分析工会覆盖对美国163所高校员工薪资的影响，发现工会带来9-11%的薪资溢价，不同职业和院校类型存在差异。
Previous studies of union wage effects in higher education have examined faculty salaries, but not staff salaries. This study, using data from a 1997–98 survey conducted by the Association of Higher Education Facilities Officers and other sources, investigates how union coverage affected staff salaries at 163 U.S. colleges and universities. The authors estimate a union salary premium of 9–11%, with variation from near zero for some of the 47 occupations in their sample to 13–16% for others, such as the skilled building trades. The union/nonunion differential appears to be larger in 2-year than in 4-year institutions, but does not vary between the public and private sectors. Where faculty members are covered by a collective bargaining agreement, unionized staff members appear to enjoy an additional salary gain of 2–3%.
