This research report [1] discusses the findings of a study conducted largely in a border town in Mexico.  The researcher conducted in-depth interviews with individuals directly engaged in the sex trade.  According to the report, previous information on human trafficking relied heavily on information provided by agencies responding to it, including advocacy groups and law enforcement, but little direct research has been conducted.  This study sought to determine the extent to which coercion and manipulation were employed and how these operations were organized.
