Price transmission in black tiger shrimp market

Abstract

This study aims to identify the transmission from domestic and export prices to farm-gate prices of tiger shrimp in Ca Mau province. Monthly series data for the analysis were collected from September 2011 to April 2017. An error correction mechanism (ECM) and linear regression model of farm- gate prices were used to explore the price transmission from domestic and export prices to farm gate prices. Research results show that in the long run, the prices of black tiger shrimp at farm gate integrate with the domestic and export prices and they positively correlate. In the short run, domestic prices are likely to have a significant effect on farm-gate prices. In fact, the relationship between export prices and farm gate prices is not statistically significant. It is also found that the dis-equilibrium of the farm gate prices on the market was adjusted for the subsequent month through the error-correction mechanism.
