Behavioral economics in the field: Estimating misreporting of condom use of female sex workers in Senegal


Abstract: Self-reported condom use is high among female sex workers in most low and middle-income countries. Because the known benefit of using condoms is high, there is a desirability bias in under-reporting socially undesirable health behaviours such as unprotected sex. We use a list randomisation to measure misreporting in condom use in Senegal, a country where sex workers face high social stigma and where AIDS epidemic is mainly concentrated among this population. Using this indirect elicitation method, we find that 22% of female sex workers did not use a condom in their last sexual intercourse with a client, which is significantly greater than the 3% obtained when asked directly. When estimating condom use among sub-groups, we find that female sex workers who are at higher risk of infection are less likely to use condoms. Our study confirms that the list randomisation is an effective method to elicit sensitive behaviours in low-income countries.

Experiments in the Social Sciences:


Experiments have become part of the scientific apparatus in social science only relatively recently compared with the status they had already acquired as a superior proof practice in the late seventeenth century in the natural sciences. For the second year, the seminar invites participants from different disciplines, such as animal studies, cognitive sciences, economics, linguistics, neurosciences, philosophy, psychology, etc., to analyse the experimental paradigm, its historical development and its epistemological constraints and tries to open the blackbox of experimental settings. That is, this seminar aims at reflecting on the status of experiments in the social sciences in a comparative way across disciplines, the part they play in providing insights and proofs, the methodological and rhetorical differences in experiments and experimental settings, the necessity and role of incentives in eliciting “truthful” answers, the transfer from results in the lab or in the “field" to the “world", the status of the theoretical models to which experimental results are compared, etc.
