Abstract
We have examined the presence of price transmission asymmetry along the value chain, and the price transmission across four main aquaculture species in Thai fish market using monthly data from January 2001 to October 2010. This is an attempt to contribute to the literature on horizontal and vertical price transmission in the seafood markets including the price transmission asymmetry in the developing countries. We did not find any evidence of asymmetric price transmission in walking catfish (except in long-run), vannamei shrimp and tilapia; however, it is evident in Thai Asian sea bass market; wholesalers exercising some market power. In general, price of one species is not found to significantly affect price of the other species at the same level of value chain.
