A study commissioned by UNICEF and Save the Children and headed by sociologist Annjanette Rosga conducted research on prostitution of children in post-war Bosnia and Herzegovina. Rosga reported that poverty was a strong contributing factor. She stated, "The global sex trade is as much a product of everyday people struggling to survive in dire economic straits as it is an organized crime problem. Attacking the crime and not the poverty is treating the symptom but not the disease...It's not uncommon for girls to know what they're entering into, and to enter voluntarily to some degree. Maybe they think they'll be different and able to escape, or maybe they'd rather take the risk than feel powerless staying at home in poverty." Jaffe and Rosen disagree and argue that poverty alone does not often force children into prostitution, as it does not exist in a large scale in several impoverished societies. Rather, a number of external influences, such as poor family situations and domestic violence, factor into the problem.
