Abstract

O objetivo deste trabalho é estimar a função de demanda de importação de vinho no Brasil. Os dados utilizados são de janeiro de 1995 a novembro de 2007, com periodicidade mensal. O modelo econométrico dinâmico de ajustamento parcial, também conhecido como modelo de Nerlove, foi o escolhido para se proceder à estimação. Este se caracteriza como um tipo de modelo autoregressivo de curto prazo, bastante apto para explicar os movimentos no quantum importado no momento atual com base nas importações passadas e no valor de outras variáveis. Concluiu-se que renda interna, preço de importação e taxa de câmbio são estatisticamente significantes para a explicação de variações na importação de vinho pelo Brasil, assim como a própria defasagem da variável dependente. Ademais, verificou-se, a partir do modelo de Nerlove estimado, o formato da estimação para períodos de longo prazo. Com base na forma funcional log-log, verificou-se que as elasticidades de longo prazo são maiores que as de curto prazo.-------------------The objective of this study is to estimate the demand function for wine imports in Brazil. The data used are from January 1995 to November 2007, with monthly frequency. The econometric model of dynamic partial adjustment, also known as Nerlove model, was chosen to make the estimate. This is characterized as a kind of short-term autoregressive model, quite able to explain the movements in the quantum imported in the current time based on past imports and the value of other variables. It was concluded that domestic income, the import price and exchange rate are statistically significant to the explanation of variations in the importation of wine by Brazil as well as the lagged dependent variable. Moreover, it was found the format of the estimate for the long-term. Based on the log-log functional form, it was found that the long-term elasticities are higher than the ones in the short-term.
