Este artigo discute a interpretacao dos indicadores de mudanca estrutural calculados com base nas matrizes de uma analise de insumo-produto. Procura-se mostrar que o modelo proposto e eficiente na identificacao e hierarquizacao das mudancas estruturais, mas nao permite, isoladamente, a determinacao das causas dessas mudancas. Sao discutidos alguns aspectos da comparacao de matrizes valoradas para um mesmo ano. Finalmente, o artigo procura compatibilizar as matrizes de insumo-produto de 1980 e de 1985, calculando a matriz para 1985 a precos de 1980, e tambem os indicadores de variacao real entre estes dois anos.

Since 1983 the Brazilian economy is transferring an increasing volume of resources which attained more than 5% of the GDP in the last two years. As a consequence of this external constraint the rate of investment has dropped from 26% of GDP in the 70's to an estimated level of 16% in the last years. This paper, using a standard macroeconomic model, establishes the relationship between alternative rates of transfer of resources, rates of domestic savings and capital output ratio with the target rate of growth of the Brazilian economy

Using an input-output framework, this article studies the consequences of income redistribution from rich people either to poor people or to the government upon the sectoral structure of the Brazilian economy in the 70s. Two main results emerge from the empirical analysis: first, agriculture is the most important sector in the generation of employment in response to transfers of income from rich to poor households; second, the urbanization which accompanied growth during the 70s favours a redistributive strategy in which the role of government becomes outstanding in terms of generation of both value added and employment.

This paper argues that in controlling public prices the Brazilian government gets into a trap: The control does not reduce inflation as expected in the first term, and it activates factors that will increase it later on. The analysis is developed for government administered prices in the area of energy, and it employs an input-output model that takes into account the direct and indirect impacts of price changes. When public prices are reduced, the impact on the inflation is small. But, since this creates financial difficulties for the public companies, they will either demand government resources or price appreciation later on, to the effect to increase inflation more than proportionally in the future.
