This article investigates the causal effect of import shocks on the wage distribution using individual-level data from the UK in the period 1997–2010. The analysis exploits regional variation in initial industrial structure and concentration for identification, and applies a group IV quantile approach to estimate the effect of import shocks on workers at different parts of the wage distribution. The study finds that the effect of import shocks generated by increased import competition is concentrated on the middle of the wage distribution: while the import shocks negatively and significantly affect workers at the bottom-middle of the wage distribution, its effect on the very bottom and upper parts of the wage groups is insignificant. Moreover, the study finds that this labour market adjustment takes place through a reduction in the hourly wage rather than a decline in total hours worked.

进口冲击对英国当地劳动力市场的分配效应

本文使用 1997 年至 2010 年期间英国的个人数据调查了进口冲击对工资分布的因果影响。该分析利用初始产业结构和集中度的区域差异进行识别，并应用第 IV 组分位数方法来估计进口冲击对工资分布不同部分工人的影响。研究发现，进口竞争加剧所产生的进口冲击的影响集中在工资分布的中部：虽然进口冲击对工资分布中底端的工人产生了负面和显着的影响，但它对最底层和最底层的工人的影响上层的工资群体是微不足道的。而且，
