Abstract
This article determines if the agricultural prices follow the asymmetric transmission mechanism. Most of the earlier studies on asymmetric price transmissions (APT) are based on models not consistent with cointegration, but this study is based on asymmetric error correction model. If the price of later stage in the marketing channel reacts more fully or rapidly to an increase(or decrease) in the price of earlier stage, it is called a positive(or a negative) APT. APT is tested for the prices of three marketing stages such as from farm to wholesale, from wholesale to retail, and from farm to retail for 21 largest agricultural products in Korea. The results show that, of 57 cases, 30 cases show evidences of negative APT, 10 cases of positive APT, 17 cases of no direction. Therefore, contrary to common senses, the negative APT is more common than the positive APT in Korean agricultural market, which is similar to the experience in European agricultural markets.
