Abstract We conduct a randomized controlled trial among women in rural Bangladesh to compare the efficacy of teaching a standard financial curriculum with maintaining a financial diary. We find that keeping a financial diary to track spending is largely as effective as financial education in improving financial test scores and downstream financial behavior. Using incentivized experiments, we also show that participants who maintained a financial diary exhibited significantly higher household bargaining power. The findings suggest that maintaining a financial diary can be a cost-effective alternative to financial education in improving the financial wellbeing of women in developing countries.
