This paper aimed to assess the changes in the consumption quantity of roasted and ground coffee in response to changes in the consumers' income, in the Southeast Region of Brazil, specifically in the states of Minas Gerais, São Paulo and Rio de Janeiro, and in all areas of the covered by the POF (Brazil). For that, the income elasticity of the consumption of those types of coffees was estimated by using an econometric model that fitted a three-segment polygon to show as the per capita physical consumption of those types of coffee varies as the per capita family monthly income changes. The data were gathered from the Family Budget Survey for the years of 2002/2003, published by the IBGE. The estimated income elasticity for roasted and ground coffee was... |

Meta-analysis us used to quantitatively summarize previous studies of residential electricity demand to determine if there are factors that systematically affect estimated elasticities. In this study, price and income elasticities of residential demand for electricity from previous studies are used as the dependent variables, with data characteristics, model structure, and estimation technique as independent variables, using both least square estimation of a semilog and maximum likelihood estimation of a gamma model. The findings of this research can help better inform public policy makers, regulators, and utilities about the responsiveness of residential electricity consumers to price and income changes. |
