Owing to a favourable economic situation and to national labour market and social protection policy reforms, Latin America has witnessed significant progress in social protection coverage. Some countries, however, have seen weaker progress, with stagnant coverage levels. Several factors underlie the extension of pensions and health care coverage and the formalization of the labour market: substantial improvements in the quality of employment, more flexible eligibility criteria for contributory coverage, and the strengthening of the supervisory and regulatory roles of the State. This article first addresses the link between social protection and informality in Latin America to show the relationship between informal labour markets, the lack of social protection and the scale of unpaid contributions. Also highlighted is regional progress in extending social protection as a result of labour market formalization. Countries in the region have used various policies to encourage formalization and these have also helped to reduce wage inequalities, since formalization has had especially beneficial effects on low-income sectors. Finally, we discuss dichotomous views on social protection financing in the region that tend to place contributory and non-contributory financing in opposition to one another but do so in favour of the latter, tend to support proposals for limited coverage, and which do not challenge the stratification of access to social protection. The move towards a convergence of benefits is deemed essential: strategies to universalize social protection in the region should not focus exclusively on increasing resources, but must address institutional change as a crucial part of the locus of innovation.
