Risk preferences and HIV/AIDS: Evidence from Senegalese female sex workers

Intervenant : Carole Treibich (GAEL, Université Grenoble Alpes)

We investigate the role of preferences for risk on health and sexual behaviours of 805 female sex workers in Senegal, of whom 441 were surveyed twice at a two-year interval. Risk preferences were measured using simple incentivised risk elicitation tasks as well as domain specific risk-taking scales. We find that the experimental measure was poorly correlated with self-reported measures. We further find that risk preferences were highly stable across domains and fairly stable over time. Our main result indicates that risk preferences measured in the lab are a main predictor of sex workers’ health and behaviours. We find that risk averse sex workers demand more preventive services and are less likely to engage in risky sex and, as a result, are less likely to be infected with sexually transmitted infections, including HIV/AIDS. Hence, our results conrm the role of risk preferences in the spread of HIV/AIDS epidemic.
