A QUESTÃO DA SEPARABILIDADE FRACA NA ESTIMAÇÃO DE SISTEMAS DE DEMANDA: UMA APLICAÇÃO PARA A DEMANDA DE CARNES NO BRASIL

Abstract

Weak separability is a frequently maintained hypothesis in demand analysis and rarely tested. This paper tested the restrictions of weak separability in a meat demand system in Brazil, using microdata from POF 2008-09. Results showed that consumers do not distinguish meats by animal type or quality and that an estimate of demand for meats without using price and expenditure of other foods incurs in omission of relevant variables, impacting cross price elasticities.
