Cultivating Self-Control in FinTech : Evidence from a Field Experiment on Online Consumer Borrowing

We report the results of a longitudinal intervention with students across five universities in China designed to reduce online consumer debt. Our research design allocates individuals to either a financial literacy treatment, a self-control training program, or a zero-touch control group. The self-control training program features detailed tracking of spending and borrowing, budgeting, and introspection about consumption choices. These sessions reduce future online borrowing and delinquency charges, mainly driven by a reduction in entertainment-related spending and borrowing. In contrast, financial literacy interventions improve test scores but only marginally affect borrowing. Our results suggest that cultivating self-regulation and budgeting skills can largely improve borrowing behavior on e-commerce platforms
