Time series of 1973-2007 along with Hodrick and Prescott filter method were employed. The results as obtained through vector error correction and Johnson model indicated that positive (negative) shocks introduce positive (negative) effects on agricultural export while positive (negative) shocks exerting negative (positive) effects on agricultural imports in the long run. . Positive vs. negative shocks bring forth symmetric (non-symmetric) effects on agricultural commodities' export (import). . . . . . . . . . . . . .
