The Supply of Skilled Labour and Skill‐biased Technological Progress
构建了一个技术选择内生的模型，发现技能劳动力增加会先降低技能溢价，随后因技术调整使技能与非技能工人工资差距扩大，并导致转型期产出增长放缓。
This paper presents a model in which the adoption of skill‐biased or 'unskilled‐biased' technologies is endogenous. In this model of endogenous technology choice, an increase in the supply of skilled labour leads to a temporary fall in the skill premium, followed by an expanding gap between the wages of skilled and unskilled workers as technologies adjust towards the more skill‐intensive mix appropriate for the greater skill of the workforce. The adjustment in the technology mix results in slower output growth along the transition path.
