IT‐Based Technical Change and Job Instability
研究了法国348个城市从1970年代中期到2000年代初信息技术扩散对就业稳定性的影响，发现IT扩散并未加剧工作不稳定性，但改变了职业结构，增加了高技能职业的份额。
Abstract We investigate the impact of IT diffusion on the stability of employment. We document the evolution of different components of job instability over a panel of 348 cities in France, from the mid‐1970s to the early 2000s. The evidence goes against the view that the diffusion of IT has spurred job instability. Yet, analysing long‐term differences in the occupational structure, we find that IT diffusion has increased the share of high‐skill occupations at the expense of low‐skill occupations. This is consistent with French firms' reliance on their internal labour market to meet the new skill requirements associated with IT diffusion.
