The effect of HIV prevention products on incentives to supply condomless commercial sex among female sex workers in South Africa.

ABSTRACT: Evidence suggests that economic factors play an important role in commercial sex work, in particular that condomless sex commands a price premium relative to condom-protected sex. This paper explores whether the use of a new HIV prevention product, with 100% efficacy but modeled after pre-exposure prophylaxis (PrEP), could change the price and quantity of condomless commercial sex supplied. We collected stated preference data from 122 HIV-negative female sex workers in urban South Africa, using a repeated choice experiment to simulate the impact of using PrEP on choices. Results suggest that the price premium for condomless sex would decrease by 73% with PrEP use and the quantity of condomless sex is predicted to increase by a factor of 2.27. Act price does not significantly affect choices
