Produtividade total dos fatores e acumulação de capital no Brasil


  • Roberto Ellery Junior

    () (Universidade de Brasília)


Este trabalho tem como objetivo avaliar o papel da produtividade total dos fatores (PTF) na determinação do produto e do investimento no Brasil. Parte significativa da discussão sobre o papel da PTF na determinação do produto é feita por meio de exercícios de contabilidade do crescimento, apesar de oferecer informações importantes esta técnica não permite avaliar o quanto do ganho de produtividade pode ser advindo do acumulo de capital e o quanto do aumento no estoque de capital pode ser devido ao aumento da produtividade. Para avaliar o papel da produtividade na determinação do capital são feitas simulações do modelo básico de crescimento, calibrado para reproduzir a economia brasileira, porém com diferentes hipóteses comportamento para a evolução da PTF. Resultados preliminares mostram que parte da acumulação de capital pode ser explicada pela PTF, desta forma políticas que visem aumentar a produtividade podem, além do efeito direto sobre o crescimento, elevar o investimento causando um impacto final maior do que o suposto nos exercícios de contabilidade do crescimento.
