Income-elasticity of poultry meat consumption in metropolitan areas of Brazil

Abstract

Studies on the meat market behavior may result in interesting parameters for the market and public policy agents. The definition of the income-elasticity of poultry consumption enables the elaboration of prospective analysis on the potential demand of this product. Thus, the main objective of the present study is to estimate the income-elasticities of poultry consumption. Data from the 1995-96 and 1987-88 Consumer Expenditure Survey, published by IBGE (Brazilian Institute of Geography and Statistics), were used in the analysis. The elasticities were obtained by fitting a three-segment polygonal curve relating the logarithm of the per capita poultry meat consumption as a function of the per capita family income. Generalized Least Squares method was used for the econometric model fitting. The elasticities were obtained considering the total, carcasses and selected individual poultry parts consumption. Average income elasticity of the total consumption enables the classification of poultry meat as a normal product. The observed average income elasticities showed that breast and thighs are superior products. In the last period, a negative elasticity was observed for carcasses.

Elasticidades-renda do consumo físico de frango – uma análise com dados das POFS de 2002/2003 e 2008/2009

“…Em ambos os casos, neste período específico, a elasticidade no primeiro estrato foi superior às dos estratos II e III. Bacchi e Spolador [6] identificaram que, em 1995-1996, as partes especiais de frango (coxa e peito) apresentavam elasticidadesmédias relativamente elevadas (1,04 e 2,41, respectivamente) 10 10 No trabalho de Bacchi e Spolador [6] , a elasticidade-renda estimada do consumo do peito de frango no estrato II está apresentada com o valor errado (6,3 Embora a elasticidade-renda do consumo físico de asa tenha sido negativa para o estrato III (−0,147), a elasticidade-média foi positiva (0,268).O consumo de asa nos estratos I e II correspondeu a 5,13%% e 49,08% do consumo físico total do bem, respectivamente.…”

“…No caso deste estudo, pretende-se atualizar as estimativas das elasticidades-renda do consumo físico da carne de frango e partes especiais estimadas por Bacchi e Spolador [6] . Apresente análise foi realizada utilizando a metodologia empregada por Hoffmann [7,8,9] e dados da Pesquisa de Orçamentos Familiares (POF) dos períodos 2002-2003 e 2008-2009 (as últimas publicadas).…”

Cross-Correlations in Meat Prices in Brazil: A Non-Linear Approach Using Different Time Scales

“…Economic studies on the meat market in Brazil have been developed basically around the price (own-and cross-price elasticities) and income elasticities of demand for meat, using classical econometrics techniques. Bacchi and Spolador (2002) analysed the income elasticity of chicken meat in Brazil, in the main metropolitan areas. The authors found that the whole chicken was a normal good, with breast and legs as superior goods and the carcass as inferior.…”
