Spatial market integration of pangasius in Bangladesh: A cointegration analysis of regional price dynamics
Abstract
The rapid growth in global aquaculture production has enabled the global supply of aquatic food to grow substantially, and much of this is linked to a growing supply of introduced species. This article explores the integration of regional markets for pangasius in Bangladesh, a now well-established aquaculture species first introduced in the early 1990s. Using bivariate and multivariate cointegration approaches on monthly retail prices, the study tested the for integration as well as the Law of One Price. The findings suggest that there is a high degree of market integration of pangasius between the regional markets and a common price determination process. As there is no exogenous price, shocks from all regions incorporate themselves into the eventual price. However, the price volatility in the Dhaka region is lower than in the other regions.
