What is the price of prevention? New evidence from a field experiment.

How does increasing access to treatment affect the demand for preventive testing? In this paper we present results from a field experiment in Nigeria in which we offered cervical cancer screening to women at randomly chosen prices. To test our hypothesis, we also offered women a lottery where the payoff was a subsidy towards the cost of cervical cancer treatment (conditional upon a diagnosis of cervical cancer). We find that women randomly selected to receive the conditional cancer treatment subsidy were about 4 percentage points more likely to take up screening than those in the control group. We also show that reducing the price of screening by 10 cents increased take-up by about 1 percentage point. These results offer compelling evidence that the optimal set of subsidies to increase take-up of preventive testing in developing countries, must include subsidies towards treatment costs (in addition to price subsidies).
