Credit effects of Pix beyond aggregate lending volumes

Determine whether Pix affects small-firm financing through changes in loan terms, borrower composition, or specific types of credit that are not captured by aggregate business-lending volumes.

Background

The paper evaluates whether Pix expands small-firm access to external finance by generating digital transaction records that could reduce information asymmetries between lenders and borrowers. Using municipality-level business-lending data, the authors find no significant increase in aggregate lending following Pix adoption, so aggregate credit expansion is not supported as the primary mechanism behind the observed wage effects.

Nevertheless, aggregate lending volumes may fail to capture changes in loan pricing, credit allocation, borrower composition, or specialized forms of financing. The paper therefore leaves unresolved whether Pix affects small-firm credit through these other margins or over a longer time horizon. Resolving this issue would help distinguish the payment-friction channel from potentially complementary financing mechanisms linking Pix adoption to small-firm expansion and labor demand.
