摘要
The aim of this work was to estimate the parameters associated to the demand for acai pulp in the retail market of Belem. Multiple regression analysis was applied to identify the key variables that impact on product consumption and to estimate the price and income elasticities and cross demand. The econometric estimation method applied was the least squares to correct heteroscedastic variance problems. Results have shown that the demand for acai pulp is price and income inelastic. Fish and cassava flour were confirmed as complementary products of strong influence on the decisions of consumers. Product quality, with regard to its association to Chagas disease, also revealed a strong influence on product choice for household consumption. Finally, the socio-economic benefit of acai pulp was R$ 762.78 million per year.
