If new technologies can broadly assist the existing labor force, or increase productivity to trigger industry expansion, then the increase in artificial intelligence is likely to go hand in hand with the increase in employment. This does not seem to be the case. On the contrary, the researchers found that the net employment of companies that have jobs that are more vulnerable to the impact of artificial intelligence has dropped sharply. This was particularly prominent from 2014 to 2018, when the number of artificial intelligence-related job vacancies in the database surged during this period.

If new technologies can broadly support the existing workforce, or increase productivity and trigger industry expansion, the increase in artificial intelligence is likely to go hand in hand with the increase in employment. This does not seem to be the case. Instead, the researchers found that net hiring by companies that were more vulnerable to AI shocks fell sharply, particularly in 2014-18, when there was a surge in AI-related job openings in databases.
