The primary objective of the study is to compare the performance of time-series models for forecasting the price of Korean ginseng. Four different types of extended AR (autoregressive) model with various rolling windows are evaluated based on the accuracy measures and optimality conditions (unbiasedness and efficiency). Results show that the proposed ARXMG (autoregressive model with monthly dummies, an exogenous acreage variable, and the conditional variance of GARCH process) model with 48-month rolling window is the best among all the models considered in this study.
