THE ESTIMATION OF MARKET INTEGRATION OF YAM MARKETING IN CROSS RIVER STATE, NIGERIA.
The study on “Estimation of Market integration for Yam Marketing in Cross River state” was conducted using four markets, i.e. two local markets and two reference markets. Data were collected using well structured questionnaire administered to 81 yam marketers. Ravallion technique was used to estimate the existence of short-run and long-run integration, to show the existence of market segmentation and also to determine the absence of local factors influencing the market. The findings revealed that short-run integration existed between Edor and Ikom markets and the coefficient of the estimated parameter for local price against the reference market was - 0.457514. This agreed with a prior expectation (if the coefficient is greater than zero, market integration exist). The result also revealed that market segmentation does not exist between Ikom and Edor markets. The study equally revealed that short-run and Long-run integration existed between Ochon and Calabar markets as the error term (Ω)≠ 0 and the coefficient was 0.015862. The study concluded that the influence of local factors, such as level of education and years of trading experience influences the prices of yam in both the local market (Edor and Ochon ) and reference markets (IKom and Calabar). Therefore the study recommends a reduction in market distortion by various market intermediaries and government should encourage yam farmers by providing effective storage facilities for yam to allow for price stabilization.
