Collective bargaining and power: Wage premium of collective agreements in Europe 2002–2018
利用欧洲收入结构调查数据，研究了2002-2018年欧洲集体谈判覆盖率的变化及其对工资溢价的影响，发现覆盖率下降与工资差异缩小相关，而工会力量减弱导致溢价降低。
Abstract This article uses the European Structure of Earnings Survey to describe the evolution of collective bargaining coverage in European countries during 2002–2018 and how this affected the pay premium associated with being covered. Pay premia are an outcome of negotiations, reflecting the bargaining power on behalf of employees as well as the system of coverage, separately for the public and private sector. Descriptively, we show a decline in collective bargaining coverage linked to a general reduction in the pay differences. This hides much variation though. In a multivariate analysis of changes over time, we show that centrally bargained agreements are associated with larger pay premia if more people are covered and in countries and sectors with stronger trade unions. As this power declines over time, so do wage premia. At higher rates of coverage, there can be a spillover effect where wages for all workers increase, thereby reducing the premia.
