We study the effects of one-to-one assistance on the social inclusion of deeply disadvantaged
informal workers, using a field experiment. We randomly assign one-to-one assistance to these
workers in a voluntary payment market. And, within this treatment group, we randomly assign
money to cover the cost of fulfilling the legal codes. We find that a worker that receives one-toone
assistance is three times more likely to comply with the legal documents required by the
government than a worker that does not received this support. Also, we find that a worker that
receives both one-to-one assistance and cost coverage is four times more likely to comply with
the legal requirements. Our findings show the importance of helping underprivileged population
through the bureaucratic process to achieve legal working permits: a one-to-one help has a huge
effect, which is increased when combined with monetary cost coverage of the legal
requirements. (JEL C93, D04, J46, J62, I30)
