How does out‐migration of skilled workers affect unskilled workers' wage in the source country? When skilled workers emigrate, unskilled wages tend to go down in some countries. If the sector that uses both skilled and unskilled workers shows a lower degree of capital intensity as compared to sectors that use only skilled workers in production, it is a common outcome. We use 19 years of cross‐country data from the International Labor Organization (ILO) spanning Asia and Latin America to show that skill emigration reduces unskilled wage unambiguously for panel fixed effects and difference generalized method of moments (DGMM) estimates. The structure is also subjected to system GMM with endogenous covariates and allied robustness checks. Importantly, we find a critical level of tertiary education, such that countries generating more skill shall face weaker negative impact on unskilled wages.

技术移民是否会伤害非技术工人？理论和跨国证据

技术工人的外移如何影响来源国非技术工人的工资？当熟练工人移居国外时，一些国家的非熟练工人工资往往会下降。如果与在生产中仅使用熟练工人的部门相比，同时使用熟练工人和非熟练工人的部门表现出较低程度的资本密集度，那么这是一个常见的结果。我们使用国际劳工组织 (ILO) 跨越亚洲和拉丁美洲 19 年的跨国数据表明，对于面板固定效应和差分广义矩法 (DGMM) 估计，技能移民明确降低了非技能工资。该结构还受到具有内生协变量和相关稳健性检查的系统 GMM 的影响。重要的是，我们发现高等教育达到了临界水平，因此产生更多技能的国家对非技能工资的负面影响将较小。
