Abstract

This study analyzed the relationship between the price of cast-iron and the price of charcoal through the estimate of the price shock of short run that the proxy variation of the price of the ton of cast-iron caused on the price of the mdc of charcoal from January, 1997 to December, 2005. A dephased model was used corrected through mobile average (MA(4)) model, allowing to conclude that the price shock was distributed in three periods. It was also concluded that the largest percentage of price variation of charcoal happened in the next month of the variation of the price of cast-iron and that the dephased model added with correction mechanisms by mobile average was efficient to estimate the price relationship of charcoal-cast-iron.
