Uma interpretação da Lei Kaldor-Verdoorn para a análise setorial do PIB, produtividade e emprego na economia brasileira

Abstract

Important performance indicators for any economy are labor market dynamics and sectoral income distribution, which are directly and indirectly related to productivity. Despite the inherent limitations of using different productivity concepts, Kaldor and Verdoorn investigated relationships between production, employment, and productivity, aiming to explain interregional and intersectoral economic dynamics. Their propositions led to the creation of the Kaldor-Verdoorn Law. The model that expresses this Law conjectures the relationships between labor productivity growth and employment in relation to income growth, providing measures of impact and returns to scale, particularly applicable to the industrial sector. The theoretical foundations intrinsic to the model were developed in this article, with empirical applications to GDP and employment series in the Brazilian economy, supporting Kaldor and Verdoorn's hypotheses regarding the elasticities estimates obtained.
