Telecommunications and adoption of Pix in Brazil

Advisor: Luiz Claudio Ferreira Sacramento Jr.

"Telecommunications internet and adoption of Pix in Brazil" In this study we observe if Pix forced telecommunications companies to expand their 4G coverage and improve service quality in municipalities lacking access to a bank branch. Using a Differences-in-Differences aproach we consider municipalities without any bank branch as a control group for the municipalities with one branch only and compare before and after Pix introduction. Our analysis focuses on the number of telecom operators and 4G service quality, providing insights into the indirect effects of Pix on market dynamics and infrastructure development in underserved areas. Our main regression shows highly significant coeficients for the effects pix had on the number of operators after its introduction, while regressions focusing on the quality of 4G shows no difference in it's quality.
