To achieve this goal, we follow Ferre and Hall (2002) who show that the existence of cointegration is a necessary but not sufficient condition to conclude that the market is not semi-strong efficient. To test this hypothesis we determined the existence of cointegration between the two sets of prices (sugar contract No. 5 in the London Market and contract No. 11 in the New York market). Our results show that there is a long term relationship, but there is not sufficient evidence to reject the null hypothesis of semi-strong efficiency in the international sugar market."
