Abstract
Neste trabalho, objetivou-se analisar o comportamento de tendência, sazonalidade e ciclos dos preços reais pagos ao produtor de leite do Rio Grande do Sul de 1973 a 2007, bem como a evolução dos preços ao consumidor e da margem de comercialização. O estudo foi realizado com base nas séries históricas de preços nominais mensais de leite pagos ao produtor e pelos consumidores no Rio Grande do Sul, obtidas junto à EMATER/RS e ao IEPE/UFRGS, respectivamente. Os preços nominais foram deflacionados para dezembro de 2007 pelo IGP-DI da FGV. Calcularam-se os Índices de Preço ao Consumidor e ao Produtor, Índices de Estacionalidade, Relativos de Ciclo e Margens de Comercialização do produto. Observou-se que os preços pagos ao produtor apresentaram tendência de queda durante toda a série histórica. O mercado de leite apresentou ciclos históricos pouco regulares até o início da década de 1980, e a partir de 1987 observou-se forte tendência de mudança na trajetória dos índices de preço ao produtor e ao consumidor. A margem de comercialização do leite cresceu no período analisado, situando-se entre 27% e 69%.
The objective of this study is to analyse tendency behaviour, seasonality and price cycles of real prices paid to milk farmers in Rio Grande do Sul between 1973 and 2007, as well as the evolution of consumer prices and commercialization margins. The study was based on historical price series of nominal monthly milk prices paid to the producer and by consumers in Rio Grande do Sul, obtained through EMATER/RS and IEPE/UFRGS, respectively. The nominal prices were deflated for December 2007 according to the IGP-DI of the FGV. Consumer and farmer Price Indexes, Seasonal Indexes, relative cycles and product commercialization margins were calculated. It was observed that the prices paid to the farmer presented a decreasing tendency throughout the whole historical series. The milk market presented historical cycles generally regular until the beginning of the 1980s, and from 1987 on, a strong tendency toward change in farmer and consumer price indexes. The commercialization margin of milk increased during the period analysed, placing itself between 27% and 69%.
