Technological Change and the Consequences of Job Loss
研究了技术变革如何解释失业后收入的大幅持续下降，发现技术变革可解释45%的收入下降，原因是工人缺乏新技能而转向低薪职业。
We examine the role of technological change in explaining the large and persistent decline in earnings following job loss. Using detailed skill requirements from the near universe of online vacancies, we estimate technological change by occupation and find that technological change accounts for 45 percent of the decline in earnings after job loss. Technological change lowers earnings after job loss by requiring workers to have new skills to perform newly created jobs in their prior occupation. When workers lack the required skills, they move to occupations where their skills are still employable but are paid a lower wage.
