Old and new forms of labour informality, linked to the structural heterogeneity of Latin America’s productive structure and emerging types of labour relations based on new technologies, is a hindrance to broadly shared progress regarding the SDGs. Through cooperation in the fields of measurement, analysis and policy advice, this project supports selected Latin American countries to identify policy options to reduce labour informality as a key instrument for “leaving no one behind”. It will work in three areas: the adjustment of labour regulations in order to cover emerging labour relations based on the application of new technologies; the analysis of changes in the composition of the occupational structure and in the demand and supply for skills; and the identification of the probability of labour informality at the sub-national level. The project aims to transfer a set of methodologies to national stakeholders as relevant inputs for policy makers to confront the challenges of informality and to foster decision making in this area through technical assistance and the promotion of dialogue on the national level.
