Yes, there have been some very successful experiments in cash transfers. Invariably, I think, the evaluations I've seen of it point to significant success and value for the families who are benefiting, but there are some risks that these are not long-term sustainable: that governments need to put in place social protection systems that enable people to access health care if there's a crisis, or to access education benefits or other benefits where they are vulnerable, and governments also need to demand that living wages or at least minimum wages be paid to adults and that appropriate regulatory frameworks are put in place.
I do think that cash transfers—both unconditional and conditional—in a number of jurisdictions have seen a decline in the incidence of child labour. We've just seen in Brazil that the Bolsa Familia, which has now been abolished, sadly, had a massive impact on reducing the incidence of child labour, but that was a fairly wide-ranging set of social protection mechanisms instituted by the government for extremely vulnerable poor families, and I would argue that those ultimately are the most sustainable.
