Skill-Biased Structural Change
研究发现，发达经济体人均GDP增长会推动高技能劳动密集型产业扩张，即技能偏向的结构性变化，从而增加对高技能劳动力的相对需求。基于美欧11国1977-2005年数据，量化模型显示，行业特定技能中性技术进步通过这一机制解释了美国技能溢价上升的18-24%。
Abstract Using a broad panel of advanced economies, we document that increases in GDP per capita are associated with a systematic shift in the composition of value added to sectors that are intensive in high-skill labour, a process we label as skill-biased structural change. It follows that further development in these economies leads to an increase in the relative demand for skilled labour. We develop a quantitative two-sector model of this process as a laboratory to assess the sources of the rise of the skill premium in the U.S. and a set of ten other advanced economies, over the period 1977 to 2005. For the U.S., we find that the sector-specific skill neutral component of technical change accounts for 18–24% of the overall increase of the skill premium due to technical change, and that the mechanism through which this component of technical change affects the skill premium is via skill-biased structural change.
