In Press at Journal of Health Economics: What is the Price of Prevention?
Testing for disease allows one to improve prognosis through early detection; however, if the potential cost of treatment is unaffordable, there is no incentive for screening. A randomized field experiment in Nigeria offered cervical cancer screening to women at randomly chosen prices, and also offered a lottery where the payoff was a subsidy towards the cost of treatment. The group offered the lottery were 4% more likely to take up screening than those in the control group, indicating that in developing countries, screening efforts must include subsidies towards treatment costs.
