Can psychology-guided information disclosure induce borrowers to lower their use of high-cost debt? In a field experiment at payday stores, we find that information that makes people think less narrowly (over time) about finance costs results in less borrowing. In particular, reinforcing the adding-up dollar fees incurred when rolling over loans reduces the take-up of future payday loans by 11% in the subsequent 4 months. Although we remain agnostic as to the overall sufficiency of better disclosure policy to “remedy” payday borrowing, we cast the 11% reduction in borrowing in light of the relative low cost of this policy.
