Modelo de Cagan e quebras estruturais: evidências para o Brasil (1970-94)

Abstract

Partindo do modelo proposto por Cagan (1956), analisa-se o comportamento da demanda por moeda e dos preços no Brasil entre 1970 e 1994. São utilizadas técnicas de cointegração robustas à presença de quebras estruturais (determinadas endogenamente), mais adequadas a um ambiente em que planos econômicos e choque externos alteraram o comportamento das séries relevantes. Também se testa a presença de bolhas racionais, a hipótese de maximização das receitas obtidas pelo governo com o imposto inflacionário e a validade da hipótese de expectativas racionais. Por fim, em abordagem pouco usual em estudos deste tipo, constroem-se medidas da magnitude dos choques na demanda por moeda. No caso brasileiro tais choques explicam uma parcela grande da variação na demanda monetária no período.

Using the model proposed by Cagan (1956), the money demand and prices are investigated in Brazilian high-inflation period between 1970 and 1994. Once the relevant series potentially have structural breaks, cointegration methods which permit changes in the cointegration vector are used. The long-run relationship between the relevant series is also used to test the presence of rational bubbles, the hypothesis of maximization of the revenues with inflation tax and the validity of rational expectation hypothesis. Finally, in an unusual approach in this literature, noise measures are calculated with respect to money demand. In Brazilian case a large portion of the variation in money demand are explained by such shocks.
