Analysis of Asymmetric Price Transmission along the Chicken and Egg Marketing Channel

Ealier attempts to test for asymmetric price transmission for agricultural market did no con-sider the chance of a short-run and long-run nonlinearities in cointegrating relationship. To over-come the weakness of previous studies, we employ nonlinear ARDL model whith has a flexible nonlinear dynamic framework capable of simultaneously and coherently modelling price asymme-tries both in the underlying long-run relationship and in the patterns of dynamic adjustment, The results suggest the following findings: In the chicken market, farm-to-wholesale marketing chan-nel shows a symmetric price transmission on both short-run and long-run, while wholesale-to-re-tail marketing channel demonstrates a asymmetric price transmission in both short-run and long-run. On the contrary, asymmetric price tansmission in the egg market is found on farm-to-wholesale marketing channel in both short-run and long-run.
