demand
A report by Ahlburg, D and Jensen, E. Commercial sex is a service and the non-price determinants of the demand for commercial sex are the same as for other commodities or services: the number of potential consumers, their preferences and incomes, the prices of other commodities and services, and perhaps their expectations of future prices and income. Since males, particularly single or divorced males, are the main demanders of commercial sex, an increase in their numbers can increase the demand for commercial sex.
