Investimento e produtividade dos fatores primários: uma análise de equilíbrio geral aplicado

The goal of this research was to analyze the effects of social expenditure and the public and private investment on the development and growth of the Brazilian Economy. The basic hypothesis verified in this research is: the success of public policy proposed by the new federal government depends on the increase of governmental investment and expenditure combined with productivity growth of primary factors. In this research the MIBRA model is used with fourth two sectors and six macro-regions. The MIBRA model database was constructed based on the Brazilian regional input-output matrix of 1999 and as well as on other statistics and information from Instituto Brasileiro de Geografia e Estatística, Banco Central do Brasil, Fundação Getúlio Vargas and many research papers. The combination of the increase of government expenditure and investment with production factor productivity can assure an economic growth of the Brazilian economy. In other hand, this economic growth in the long run could increase the regional inequalities among regions in terms of economic development and economic growth. The increase of the primary factors productivity gives more “elastic” results of investment and governmental expenditure increasing.
