Oferta e demanda de frango de corte no Brasil

Abstract

This work was carried out with the objective of studying poultry supply and demand in the State of Rio Grande do Sul and in Brazil. Time series data referring to 1972 - 1988 were used. Both supply and demand were analysed according to a mathematical model which was based on the functional form CobbDouglas. Parameters were estimated on the basis of two-stage least squares (TSLS). As to supply and demand an econometric model was developed according to a simultaneous equation system. The main results found were as follows: Price policies aiming to increase poultry production may be more effective in comparison with those practiced in the basic inputs. Policies drwing towards the commercialization process aiming margins reduction tend to be more effective especially through a system which enables the poultry raisers to improve their organization. Price "freezing" policies as those which have been implemented in Brazil since 1986 were found to be ineffective in the face of elastic demands. Income allocation policies would be beneficiai to both the poultry sector and the lower income population if they were implemented through social programs including the poultry as an item of. The results showed a substitution relation between poultry meat and beef, pork and lamb meat.
