Economic models suggest that competition will prevent those subjected to discrimination from being affected adversely. This column uses an unusual case study of sex workers in Singapore to reveal that having many actors on both sides of the market does not, in fact, eliminate discrimination. Policy intervention remains the best tool to end price discrimination.

Addressing the HIV/AIDS epidemic requires an understanding of how risky sexual behaviours change over time. This column observes that, whereas the accuracy of self-reported data depends on the likelihood of people telling the truth, the likelihood of risky behaviours being detected in tests for sexually transmitted infections is equal to the disease transmission rate. Self-reported data may therefore be a more reliable measure of risky behaviours than the prevalence of sexually transmitted infections when the probability of transmission is low.

Paul Seabright of the Toulouse School of Economics talks to Viv Davies about his book, "The War of the Sexes: how conflict and cooperation have shaped men and women from pre-history to the present”. He explains how game theory can shed light on the complex dynamics that create both conflict and cooperation between the sexes. They discuss the connection between the rise of modern capitalism and the rise of feminism, monogamy and marriage and whether there will ever be sexual equality.

It argues that shame is an important driver of sexual behaviour among teenagers even when peer-group effects are considered.
