**By EconLib**

California’s $20 minimum wage for fast food workers is triggering a wave of substitution effects, as businesses adapt to the higher labor costs. This phenomenon, where consumers and businesses shift towards cheaper alternatives when a product’s price increases relative to others, is playing out in the Golden State’s food industry.

One consequence is a shift in consumer preferences away from fast food establishments and towards more expensive dine-in restaurants. While the absolute price of dine-in restaurants hasn’t changed, the relative price difference between fast food and sit-down dining has narrowed. This incentivizes consumers to opt for higher-quality dining experiences even if it means spending slightly more.

Another response is the rise of automation in the fast food industry. Chipotle, a major chain, has begun deploying robots that can peel and cut avocados, as well as portion salads and bowls. The company hopes this automation will reduce labor costs, demonstrating the substitution effect in action. Even if the initial cost of these machines is higher than human labor, the minimum wage law has made automation relatively less expensive, making it a viable alternative.

Beyond robots, restaurants are also finding ways to substitute customer labor for employee tasks. Many restaurants have implemented self-serve kiosks for ordering, eliminating the need for cashiers. Customers are also increasingly responsible for bussing their own tables, reducing the need for bussers.

These examples highlight the intricate dynamics of the substitution effect in response to minimum wage increases. While the intent of minimum wage laws is to improve worker wages, the unintended consequence can be job losses and a shift towards automation. The article argues that understanding the substitution effect is crucial for effective economic policy, as it demonstrates the complex interplay between prices, consumer behavior, and technological innovation.
