Services offshoring and wages: evidence from micro data
利用英国个体层面数据，研究发现服务离岸外包降低了低技能和中技能工人的实际工资，但提高了高技能工人的工资，从而扩大了技能工资差距。
This paper investigates the effects of services offshoring on wages using individual-level data combined with industry information on offshoring for the United Kingdom. Our results show that services offshoring affects the real wage of low- and medium-skilled individuals negatively. By contrast, skilled workers may benefit from services offshoring in terms of higher real wages. Hence, offshoring has contributed to a widening of the wage gap between skilled and less skilled workers. This result is obtained while controlling for individual and sectoral observed and unobserved heterogeneity. In particular, our empirical model also controls for the impact of technological change and offshoring of materials.
