Desirable actions such as enrolling children in school or receiving vaccinations can be encouraged by a form of aid known as conditional cash transfers. In Mexico, for example, dropout rates of 16- to 19-year-olds in rural area dropped by 20% and children gained half an inch in height. Initial fears that the program would encourage families to stay at home rather than work to collect benefits have proven to be unfounded. Instead, there is less excuse for neglectful behavior as, for example, children stopped begging on the streets instead of going to school because it could result in suspension from the program.
