In the last week of my ECONS102 class, we covered inequality. In discussing the structural causes of inequality, I go through a whole bunch of causes grouped together under a heading of 'structural changes in the labour market', one of which is skills-biased technological change. The basic idea is that over time, some technology (like computers) has made people in professional, managerial, technical, and creative occupations more productive or allowed them to reach larger audiences at low cost. However, other technology (like robots) has tended to replace routine jobs in sectors like manufacturing. This has increased the premium for skilled labour, increasing the ‘gap’ between skilled and unskilled wages.
In discussing this idea of skills-biased technological change this year, I mused about the potential impact of generative artificial intelligence, and whether skills-biased technological change was about to reverse, leading to job losses in professional, managerial, technical, and creative occupations, while jobs in activities that might broadly be grouped into manual and dexterous labour (like plumbers, electricians, or baristas) would remain. A change like that would likely reduce inequality (but not necessarily in a good way!).
The truth is, I don't think that economists have a good handle on what the impacts of generative AI will be on the labour market. On the one hand, you have some economists like Stanford's Nick Bloom, claiming that a lot of jobs (in particular tasks or occupations or sectors) are at risk. The loss of low-productivity, low-wage jobs that Bloom considers at risk, like call centre workers, will likely increase inequality further. On the other hand, you have other economists like MIT's Daron Acemoglu, claiming that the impact of generative AI on inequality will be small.
Given that economists can't agree on this, it is interesting to know what the general public thinks. That's the question that this post on Liberty Street Economics by Natalia Emanuel and Emma Harrington addresses. Using data from the February 2024 Survey of Consumer Expectations, they report that:
In general, a substantial share of respondents did not anticipate that genAI tools would affect wages: 47 percent expected no wage changes. These beliefs did not differ significantly based on prior exposure to genAI tools.
However, respondents believed that genAI tools would reduce the number of jobs available. Forty-three percent of survey respondents overall thought that the tools would diminish jobs. This expectation was slightly more pronounced among those who had used genAI tools, a statistically significant difference.
And specifically in terms of inequality:
We find that those who have used genAI tools tend to be more pessimistic about future inequality. Specifically, we asked people whether they thought there would be more, less, or about the same amount of inequality as there is today for the next generation... while 33 percent of those who have not used genAI tools think there will be more inequality in the next generation, 53 percent of those who have used genAI tools think there will be more inequality. This gap persists and is statistically significant, even after controlling for other observable traits.
So, a large minority of the general public seems to be concerned about generative AI's impact on inequality, and that concern is greater among those with experience (where a small majority believe inequality will increase). Now, it could be that those with greater experience are better able to accurately assess the risks to their own (and others') jobs from generative AI. Or maybe people who use generative AI are simply more likely to have read the AI doomers' predictions of an AI apocalypse (or equally, they could be more likely to read the bullish views of AI proponents). The general public may not know that they fear skills-biased technological change, but they may intuitively understand the potential risks. The real question, which we still cannot answer, is whether those risks are real or not.
