“…Turning our attention to the impact of innovation on workers' skills, the literature on SBTC has underlined a substitution effect between new technologies and unskilled workers, and a positive relationship between new technologies and skilled (white-collar) workers. At the same time, some recent literature either do not find the skill-bias (Hirvonen et al, 2022) or suggest that innovation generates a general positive impact at the firm level in terms of labour quality (Bessen et al, 2022), suggesting that the key issue is not skilled vs. unskilled, but rather the difference across firms in terms of innovativeness and across jobs in terms of task content. In parallel, the empirical literature has focused on different categories of exposed workers, focussing on routinised vs. non-routinised tasks and occupations, or manual vs. cognitive tasks and occupations.…”
