Resumo
O mercado de café robusta tem experimentado mudanças caracterizadas pelo crescimento da demanda e pela confirmação do Vietnã como maior produtor e exportador, ultrapassando tradicionais produtores, como a Indonésia. Essas alterações motivaram a análise da integração entre os preços internacionais e os principais mercados dessa commodity: Vietnã, Brasil, Indonésia e Índia. Foi testada a hipótese de que o Vietnã transmite choques de preços aos demais mercados. Analiticamente, utilizou-se a análise de co-integração e o modelo VEC. Constatou-se que, no período de 1988 a 2005, o preço externo e os do Vietnã, Brasil e Indonésia foram integrados; o preço da Índia foi influenciado por fatores que não são comuns aos demais países. Não houve perfeita integração e o Vietnã, embora importante, não foi o mercado mais interdependente.
The robusta coffee market has experienced changes which are characterized by a growth in the demand and the confirmation of Vietnam as the world’s greater producer and exporter leaving behind traditional producers as Indonesia. These changes motivated the analysis of international price integration and the main markets of this commodity: Vietnam, Brazil, Indonesia and India. It was tested the hypothesis that Vietnam transmits prices shocks to the other markets. The framework used the analysis of co-integration and the Vector Error Correction (VEC) model. It was shown that, in the period from 1988 to 2005, the foreign price and the ones from Vietnam, Brazil and Indonesia were integrated and the India’s price was affected by factors that are not common to the other countries. There was no perfect integration and Vietnam, although important, wasn’t the more interdependent market.
