Using Lotteries to Incentivize Safer Sexual Behavior : Evidence from a Randomized Controlled Trial on HIV Prevention

Financial incentives are a promising HIV prevention strategy. This paper assesses the effect on HIV incidence of a lottery program in Lesotho with low expected payments but a chance to win a high prize conditional on negative test results for sexually transmitted infections. The intervention resulte...

This paper assesses the effect on HIV incidence of a lottery program in Lesotho with low expected payments but a chance to win a high prize conditional on negative test results for sexually transmitted infections. The intervention resulted in a 21.4 percent reduction in HIV incidence over two years. Lottery incentives appear to be particularly effective for individuals willing to take risks. This paper estimates a model linking sexual behavior to HIV incidence and finds that risk-loving individuals reduce the number of unprotected sexual acts by 0.3/month for every $1 increase in the expected prize. 2015-03-31T15:34:35Z 2015-03-31T15:34:35Z 2015-03 Working Paper http://hdl.handle.net/10986/21654 en_US Policy Research Working Paper;No. 7215 CC BY 3.0 IGO http://creativecommons.org/licenses/by/3.0/igo World Bank World Bank Group, Washington, DC Publications & Research Publications & Research :: Policy Research Working Paper Africa
