Abstract: A long-standing debate concerns whether technological change widens wage gaps by benefiting skilled labor. We show that financial technologiesspecifically, instant payment systemscan instead reduce wage inequality. Using an administrative dataset covering all registered employees in Brazil, we study the nationwide rollout of Pix, an instant payment platform introduced in late 2020. Our empirical strategy is a triple difference-in-differences design that exploits variation in preexisting mobile penetration across municipalities, the differential benefits of Pix for cash-intensive versus non-cash-intensive sectors, and the timing of Pixs rollout. A one standard deviation increase in mobile penetration leads to a 1.2 percent wage increase in cash-intensive sectors relative to non-cash-intensive sectors following Pixs introduction. These wage gains are concentrated among workers with less education, reducing the college wage premium by 1 percentage point. Further evidence suggests that increased small-business labor demand, amplified by local labor market frictions, drives these effects. Overall, instant payment systems disproportionately benefit small, cash-intensive businesses, enhancing labor demand in sectors reliant on low-skill workers and highlighting how financial technologies can shape distributional outcomes differently from skill-biased technologies.
