Prize-linked Savings Initiatives for Promoting Better Health and Economic Outcomes in Kenya

Despite a large decline in new adult HIV infections in eastern and southern Africa from 2005-2015, progress has slowed in recent years. In particular, HIV risk among adolescent girls and young women remains high. Transactional sex, or the exchange of material support in non-commercial sexual relationships, is widely believed to be among the main driving factors for the HIV risk in this population. There is a large gap when it comes to interventions targeting men who engage in transactional sex. The proposed pilot project seeks to fill this important gap by using behavioral economic principles to promote behavior change among men.

The project will assess a novel prize-linked savings intervention designed to shift men's income away from alcohol and transactional sex and towards saving for the future. Prize-linked savings accounts offer savers a random, lottery-like payout proportional to the amount participants save, instead of traditional interest income. A number of banks, employers, and policymakers have promoted this low-cost, scalable approach to increasing savings among low-income individuals. However, there have been no assessments of whether prize-linked savings interventions can induce changes in key health-related behaviors as well. We will conduct a pilot randomized trial among men in Kenya to assess whether offering prize-linked savings opportunities leads to reduced spending on alcohol and transactional sex. The project will enroll men who in communities with high HIV risk, randomize them to the savings intervention, and assess changes in key economic and self-reported health outcomes over a 3-month period with baseline and follow-up surveys. We hypothesize that men randomized to the prize-linked savings intervention will have higher savings, lower expenditure on transactional sex, alcohol, and gambling, and lower rates of participation in risk behaviors such as transactional sex, relative to men randomized to the standard bank account control group.
