Análise dos índices dos efeitos multiplicadores e das ligações para trás e para frente da renda, do produto e do emprego: uma abordagem a partir da matriz de contabilidade social do Brasil

Abstract

The main objective of this paper is to analyze the multiplier effects of income, output and employment, as well as the inter-sectorial backward and forward linkages of income, output and employment of the key industries of the Brazilian economy in the years 2000, 2005 and 2010, based on Social Accouting Matrix (SAM) of Brazil. The research sought to analyze the interactive impacts caused by the transformation industry in its own internal sectors and sectors of other industries that form the Brazilian industrial system. The chain indices of dispersion power and dispersion sensitivity of the manufacturing industry over all sectors of the industrial system of the Brazilian economy based on SAM were also analyze. The article found that income that exceeds the portion of the purchase of inputs was spending by households, using the channels that result in extra demand on the products of the agricultural sector, through the liquid circular effect of Stone. Therefore, it strengthened demand links, which, in turn, catalyzed the process that led to the spread of national GDP growth. The role of the manufacturing industry is thus perceive as a key industry for the country's economy, especially as the back bond index and the forward index are high and their coefficients of variation low.
