Okay.
Some of these interventions can be very low cost, and you've put your finger on poverty as the main driver. For example, we found that free lunches at schools are often enough to lower child labour rates, because families know that if they send their child to school, they'll get at least one good meal a day.
These cash transfer programs that Aidan and I have both been speaking about can also be very low cost. In Morocco, they found that $7 per child per month was enough to dramatically reduce child labour rates and increase school enrolment. Just providing a small stipend for poor families can make a big difference.
