LABOR INSPECTION IN BRAZIL: A PROPOSAL FOR A MULTILEVEL COMPOSITE INDICATOR

The objective of this study is to propose a multilayer DEA model (MLDEA) for the construction of a composite indicator to assess occupational health and safety in the Brazilian states. In traditional DEA models for the construction of composite indicators, all indicators are treated equally because they belong to the same layer, however, placing all indicators in the same layer can lead to a weak power of discrimination and the allocation of unrealistic weights. Therefore, the proposed structure is divided into six levels related to aspects of occupational health and safety: FGTS, Infraction Notices, quota for people with disabilities, work accidents, slave labor and child labor. Therefore, the proposed model will provide a more detailed analysis of efficiency considering the different levels, leading to a model with greater power of discrimination.
