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.

技能偏向的结构变化

通过使用广泛的发达经济体，我们记录了人均 GDP 的增长与高技能劳动力密集型部门的附加值构成的系统性转变有关，我们将这一过程称为技能偏向的结构性变化。因此，这些经济体的进一步发展导致对熟练劳动力的相对需求增加。我们开发了这一过程的定量两部门模型，作为实验室来评估 1977 年至 2005 年期间美国和其他十个发达经济体的技能溢价上升的来源。对于美国，我们发现技术变革中特定行业的技能中性成分占技术变革导致的技能溢价总体增长的 18-24%，
