From Job Loss to Automation: There Is a Real Price of Minimum Wage Laws

I have found fewer economic topics that have been more divisive for economists than the minimum wage debate. For advocates, it is a moral and economic imperative to help provide a living wage so no one ends up in poverty. For critics, minimum wage has unintended consequences that make matters worse, especially for the low-skilled workers minimum wage was meant to help. As minimum wages increase higher and higher, a new wave of research gives us a sense of what is to come with higher minimum wages. Today, I will cover some of the most recent research conducted on the topic of minimum wage.

The first is a working paper from the National Bureau of Economic Research on the increased minimum wage for fast food workers in California that was released last month (Clemens et al., 2025). This research found that increasing minimum wage to $20 decreased employment by 2.7 percent, or a reduction of 18,000 people. This is even more jarring given that this minimum wage increase only applied to fast-food restaurants with over 60 locations. 

Why does this happen? This is not mere theoretical. It is Supply and Demand 101 in action. Two phenomena take place when the minimum wage becomes higher than what businesses are paying. One is an increase in people who want to work for the higher wage. The second phenomenon is that fewer businesses want to pay, since workers are now more expensive. As a result of these two phenomena, the result is a labor surplus in the market, which is another way of saying that minimum wage causes greater unemployment. 

This NBER research makes a new contribution to the debate. Minimum wage proponents often argue that the benefits of higher pay outweigh the job losses, as this 2024 research paper does. However, the new NBER paper estimates that 29 to 49 percent of the wage gains were offset by job losses. This does not even get into the social or psychological costs of unemployment, not to mention how unemployment has the potential to slow one's career development and worsen the trajectory for lifetime earnings. 

This segues us into an interrelated phenomenon: automation. Automation is the use of machines, technology, and software to perform tasks that were previously performed by humans. I call automation interrelated because not all job losses are due to automation and not all automation results in job losses. 

All the same, automation is a response to higher minimum wage laws. Last week, the think tank Cato Institute released a policy brief entitled The Minimum Wage and Automation (Nain and Wang, 2025). This brief explores how minimum wage hikes led to greater automation-related patent applications. The researchers found that when there is a 10 percent increase in these patent applications, there is a 1.6 percent decline in employment share for workers in routine jobs without an education, as well as a 1.2 percent drop in their wages. How does this happen? 

By definition, minimum wage is an increase in labor costs. Minimum wage laws disproportionately impact industries that rely on low-wage, routine-task workers. In response, firms eyeing automation either decide to adopt existing automation technology or invest in new automation technology. This demand drives innovation from manufacturing and tech industries, which increases the opportunities to supply automation services to other end-users. This means that as automation increases, jobs entailing repetitive routine tasks are more susceptible to being permanently replaced. 

Minimum wage increasing automation is a finding that is confirmed by a study from Nature released this past June finding that an increase in minimum wage in Europe resulted in an increase in robot installations (Sharfaei and Thavorn, 2025). This Nature study shows that the deleterious effects of minimum wage are not confined to a certain industry or a specific country. 

Laws of economics do not get suspended simply because proponents want their favored policy to work. There are real-life consequences and tradeoffs to minimum wage laws. Job loss and automation are two outcomes. There are also the effects of reduced work hours, increased consumer prices, prolonged recessions, and an increased federal budget deficit. It is no wonder that minimum wage does nothing to reduce poverty. In the end, policies driven by good intentions that ignore economic realities only serve to hurt the people they were meant to help. Workers deserve better than having to navigate a labor market distorted by wage mandates that make it more difficult to find and keep a job.
