Abstract

Este artigo tem por objetivo analisar a natureza aleatória dos índices de preços. Considerando particularmente a categoria dos Índices de Preços ao Consumidor (IPC); parte-se do conceito teórico de Índices de Custo de Vida, do qual o IPC é uma aproximação, para destacar os aspectos que tornam o índice intrinsecamente estocástico. Além disso, o IPC está sujeito a imprecisões decorrentes das diversas etapas de amostragem que o seu cálculo efetivo requer. Utilizando dados do IPC-Fipe para o período de janeiro de 1989 a dezembro de 2000, avalia-se o impacto do erro associado à amostragem de informantes de preços sobre a precisão do índice.
