Abstract in Portuguese
Este trabalho propõe realizar uma comparação entre os Modelos Auto-Regressivo e Estrutural para explicar séries econômicas que apresentam um padrão sazonal que se altera lentamente com o decorrer do tempo. De acordo com a especificação do Processo Gerador de Dados utilizado neste trabalho, os resultados obtidos confirmam que o Modelo Estrutural se adapta melhor aos dados quanto menor a magnitude dos choques sazonais vis-à-vis os choques de interesse primário. Além disso, apresentamos um estudo sobre a importância da inclusão do efeito de feriados móveis em séries econômicas brasileiras.
