Original title: Financial Technologies, Labor Markets, and Wage Inequality: Evidence from Instant Payment Systems

New technology often widens the pay gap by helping skilled workers most. Researchers wanted to see if fast digital money transfers do the same. They studied the launch of Pix, an instant payment system in Brazil. By lowering payment frictions, or the extra costs and hassles of handling cash, Pix made it easier to do business. Small firms benefited greatly, and their demand for workers jumped. Consequently, pay at small firms increased significantly compared to big firms. These wage gains showed up mostly in cash-heavy sectors like retail and services, rather than wholesale or manufacturing. Because pay grew specifically for workers in the lower half of the wage ladder, overall wage inequality actually shrank.
Imagine a small market where vendors accept only cash. Customers have to go to an ATM first, which takes time, and some people give up. That means fewer sales for the vendor. Now suppose a new payment method lets anyone tap their phone. Suddenly, more people can buy, so the vendor sells more and needs to hire extra help. In this paper, Pix is that new payment method for small businesses in Brazil. By removing the cost and hassle of handling cash, it lets small shops grow and pay their workers more, shrinking the gap with big stores.
Most new technologies widen the gap between high- and low-paid workers. But Brazil's instant payment system, Pix, actually shrinks it: wages rise for lower-paid workers in small shops and restaurants, while top earners are unaffected. This shows that a simple payment upgrade can help reduce inequality, not increase it.
The findings are specific to Brazil's Pix and may not hold in other contexts. The wage gains are limited to cash-intensive sectors like retail and services; no effects are found in wholesale or manufacturing. The inequality reduction comes from lifting the bottom, with no change at the top. The model-based predictions of broader effects depend on calibration assumptions.
