Description
Summary:This paper has contributed the study of the functional forms of aggregate demand of aliments, by using the date of ENDEF, a technique of Box-Cox and traditional models of demand. Their results have shown that the use of functional form would arbitrate a tendency with an error of estimation up to 552%. Anyway, it veriful that the obtained results with the procedure of Box Cox an perfectly currents with a priori expectations and with the empirical evidence pennilty a superior adjustment to the results obtained by traditional models.<p><p>Contribuição ao estudo das formas funcionais de demanda agregada de alimentos, utilizando dados de corte seccional do ENDEF, a técnica de Box-Cox e modelos tradicionais de demanda. Resultados mostraram que o emprego de formas funcionais arbitrárias tende a produzir erros de estimação em até 552%, Verificou-se, também, que resultados obtidos com o procedimento de Box-Cox, são perfeitamente coerentes com as expectativas a priori e com evidência empírica, permitindo um ajustamento superior ao obtido pelos modelos tradicionalmente utilizados.
