Ability-Biased Technological Transition, Wage Inequality, and Economic Growth
构建了一个能力偏向技术转型的增长模型，解释美国等发达国家过去几十年中技术进步、教育程度与工资不平等的演变，发现技术进步加速会提高能力回报，加剧技能组内和组间的工资不平等，并导致非熟练工人平均工资暂时下降和生产率暂时放缓。
This paper develops a growth model characterized by ability-biased technological transition in which the evolution of technology, education attainment, and wage inequality is consistent with the observed pattern in the United States and other advanced countries over the past several decades. It argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers, an increase in average wages of skilled workers, a temporary decline in average wages of unskilled workers, an increase in education, and a productivity transitory slowdown.
