Automation of Workplaces

Since the dawn of the Industrial Revolution, workers like the Luddites in 19th century Britain have feared that they will be replaced by machines and left permanently jobless. To date, these fears have been mostly wrong—but not entirely. In a chapter in “Shifting Paradigms,” I examine the implications of automation for jobs and wages.

AUTOMATION, JOBS, AND WAGES

On one hand, automation often creates as many jobs as it destroys over time. Workers who can work with machines are more productive than those without them; this reduces both the costs and prices of goods and services, and makes consumers feel richer. As a result, consumers spend more, which leads to the creation of new jobs.

On the other hand, there are workers who lose out, particularly those directly displaced by the machines and those who must now compete with them. Indeed, digital automation since the 1980s has added to labor market inequality, as many production and clerical workers saw their jobs disappear or their wages decline. New jobs have been created—including some that pay well for highly educated analytical workers. Others pay much lower wages, such as those in the personal services sector.

More broadly, workers who can complement the new automation, and perform tasks beyond the abilities of machines, often enjoy rising compensation. However, workers performing similar tasks, for whom the machines can substitute, are left worse off. In general, automation also shifts compensation from workers to business owners, who enjoy higher profits with less need for labor.

Very importantly, workers who can gain more education and training, either on the job or elsewhere, can learn new tasks and become more complementary with machines. For instance, while robots have displaced unskilled workers on assembly lines, they have also created new jobs for machinists, advanced welders, and other technicians who maintain the machines or use them to perform new tasks. In general, workers with at least some postsecondary credentials are often made better off, while those without them often suffer losses.

THE NEW AUTOMATION: IS THIS TIME DIFFERENT?

The “new automation” of the next few decades—with much more advanced robotics and artificial intelligence (AI)—will widen the range of tasks and jobs that machines can perform, and have the potential to cause much more worker displacement and inequality than older generations of automation. This can potentially affect college graduates and professionals much more than in the past. Indeed, the new automation will eliminate millions of jobs for vehicle drivers and retail workers, as well as those for health care workers, lawyers, accountants, finance specialists, and many other professionals.

The new automation will eliminate millions of jobs for vehicle drivers and retail workers, as well as those for health care workers, lawyers, accountants, finance specialists, and many other professionals.

So we must ask: Is this time really different? Will the ability of workers to adapt to automation by gaining new education and skills be swamped by the frequency and breadth of tasks that machines with AI will perform?

AI will increase the challenges many workers will face from automation, while still contributing to higher standards of living due to higher worker productivity. At the same time, we will need a much more robust set of policy responses to make sure that workers can adapt, so that the benefits of automation are broadly shared.

POLICY IMPLICATIONS

New and better policies should be adopted in the following areas: education and training, “good job” creation by employers, and wage supplements for workers.

Our most important challenge is to improve the breadth and quality of education and training. To become complementary to AI, more workers will need what researchers call 21st century skills. These include communication, complex analytical skills that often require careful judgements of multiple factors, and creativity. The onus is on K-12 and postsecondary schools to adapt and provide greater emphasis on teaching such skills.
