A model of wage and employment effects of service offshoring
本文构建了一个两部门模型，分析技能充裕的高生产率国家如何离岸外包更多非技能任务，并发现随着任务可贸易性下降，离岸外包对工资和就业的影响由负转正，且技能任务在更高可贸易性水平上发生转变。
Abstract This paper develops a two‐sector model of trade in goods and intermediate tasks that differ in tradability and skill intensity. A skill‐abundant country with high productivity is shown to offshore more unskilled tasks than skilled tasks, without relying on a particular correlation structure between tradability and skill intensity. With putty‐clay technology that allows retraining in the long run, transition from the non‐offshoring to the offshoring equilibrium generates wage and employment effects that switch from negative to positive as tradability declines, with the switches occurring at a higher degree of tradability for skilled tasks. This is consistent with the empirical literature.
