Tips Raise Worker Value and Profits

Using linked point‑of‑sale and payroll data for 20,000 U.S. firms, the study finds tips form a near‑constant share of revenue. When firms adopt tipping they cut base wages (about $0.23–$0.33 per tip dollar), but tipping raises worker effort and output so that workers earn more and firms recover roughly a third of tips—raising estimated job value by ~50% and firm profit by ~30% where customers tip. — This reframes tipping from a marginal social norm into an economic instrument that reallocates pay, alters firm incentives, and can explain tipping's recent spread across industries—implicating labor policy, minimum‑wage debates, and business models.
