The heterogeneous effects of technology shocks. Evidence from the Czech Labour market
利用捷克行政劳动力数据，研究发现技术冲击对高工资工人增加工时，对低工资工人减少工时，且影响因性别、教育水平和行业而异。
This paper uses administrative labour market data from Czechia to investigate the heterogeneous effects of technology shocks. Using a FAVAR, the shock is identified using medium run restrictions à la Uhlig (2004b). The shock has a positive effect on hours for workers with wages at and above the median, while there is some evidence that workers on low wages reduce their hours. Analysis of industrial and demographic groups indicates that the former group is likely to consist of males, to be educated or to work in services. • Examine the effect of productivity shocks on the distribution of hours using granular data from Czechia. • Average hours decline after a technology shock but there is substantial heterogeneity. • Workers on low wages reduce hours but hours rise for those on higher wages. • Hours increase for male workers, those who are more educated or work in the service industry.
