Higher labor costs are cited by some economists as one factor, among several, that can accelerate a business's adoption of automation technology, like self-checkout kiosks or ordering tablets, to replace certain lower-wage roles. Employers facing higher mandated wages may accelerate investment in self-checkout, ordering kiosks, or other labor-saving technology sooner than they otherwise would have. This automation concern is increasingly part of the broader minimum wage debate. Critics argue this substitution effect is a predictable response to rising labor costs.
