Resumo: | Weak separability is a frequently maintained hypothesis in demand analysis and it’s 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 distinguishmeats 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. |

Este estudo buscou testar essa hipótese em um sistema de demanda por carnes no Brasil, utilizando os microdados da POF 2008-09. Concluiu-se que os consumidores não separamcarnes por tipo de animal ou por qualidade da carne e que uma estimação de demanda de carnes sem utilizar preço e dispêndio com outros alimentos incorre em omissão de variáveis relevantes, influenciando nas estimativas das elasticidades-preço cruzadas.Universidade de São Paulo, FEA-RP/USP2015-09-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistas.usp.br/ecoa/article/view/10604510.1590/1413-8050/ea135987Economia Aplicada; Vol. 19 No. 3 (2015); 507-539Economia Aplicada; Vol. 19 Núm. 3 (2015); 507-539Economia Aplicada; v. 19 n. 3 (2015); 507-5391980-53301413-8050reponame:Economia Aplicadainstname:Universidade de São Paulo (USP)instacron:USPporhttps://www.revistas.usp.br/ecoa/article/view/106045/104697Copyright (c) 2015 Economia Aplicadainfo:eu-repo/semantics/openAccessTravassos, Guilherme FonsecaCoelho, Alexandre Bragança2016-02-03T16:59:16Zoai:revistas.usp.br:article/106045Revistahttps://www.revistas.usp.br/ecoaPUBhttps://www.revistas.usp.br/ecoa/oai||revecap@usp.br1980-53301413-8050opendoar:2023-09-13T12:17:04.291942Economia Aplicada - Universidade de São Paulo (USP)false |
