The effects of the decentralization of collective bargaining on wages and wage dispersion: Evidence from the Finnish forest and IT industries
利用芬兰森林和IT行业从行业级转向企业级集体谈判的自然实验，研究发现谈判分散化对工资水平和离散度总体影响微弱，仅造纸业蓝领工人工资和内部离散度显著上升。
Abstract Recently, Finnish forest industries shifted from sectoral collective bargaining to firm‐level bargaining, and the IT services industry shifted to a hybrid of sector‐ and firm‐level bargaining. Using administrative data on monthly wages and the synthetic difference‐in‐differences method, I study the causal effects of collective bargaining decentralization on the level and dispersion of wages. Despite the substantial change in the level of collective bargaining, I generally find muted effects on the level and dispersion of wages. I find positive and economically and statistically significant effects on wage levels and within‐firm wage dispersion only for blue‐collar workers in the paper industry.
