Much of the literature on market integration in developing countries focuses on spatial price differentials for a single commodity. This study adapts M. Ravallion's (1986) model of dynamic integration to a multicommodity framework. Moreover, it uses cointegration models to explore how a single market uses information about prices of one commodity to form the price of a second. The two approaches then test different aspects of market efficiency. Jointly they indicate functional, albeit imperfect, intercommodity price transmittal in a West African setting.
