Unions, Wages and Hours
利用美国当前人口调查50年数据，发现工会与非工会会员的时薪差异自大衰退以来持续下降，但周薪差异更稳定，源于工会既提高时薪也延长工时，并缓解就业不足。
ABSTRACT We examine union‐non‐union differentials in wages and hours in the United States over the last 50 years using data from the Current Population Survey. The regression‐adjusted difference between union members’ and non‐members’ hourly earnings has been falling since the Great Recession. The union differential in weekly wages has been more stable. Although it fell by around 5 log points during COVID, it remains 15 log points. This weekly earnings differential arises from both a higher hourly wage of around 10 log points and longer working hours (5 log points). The working hours differential partly reflects unions’ ability to tackle under‐employment, such that union workers work closer to the hours they desire than their non‐union counterparts. The traditional focus on hourly wage differentials underplays the important role trade unions play in maintaining members’ weekly earnings by ensuring workers receive the paid hours they desire.
