This indicate no price transmission, which means there is price discrepancy of Indonesia with world market and importing countries. This study examined degree of integration and price efficiency of Indonesia cocoa beans with world market and importing countries. Integration analysis using Cointegration Johansen approach, Vector Autoregression (VAR)/Vector Error Correction Model (VECM) and price efficiency analysis using the Generalized Autoregeressive Conditional Heteroscedasticity (GARCH) approach . The results showed that the price of Indonesian cocoa beans integrates long term with the price of cocoa beans in the world market (New York Board of Trade) and India.
