Abstract
This study aims to analyze the impact of black tiger shrimp prices and other factors on shrimp area in Mekong Delta using the supply response function based on a partial adjustment model of Nerlove. The model uses panel data gathered in four provinces, namely, Ca Mau, Bac Lieu, Soc Trang, and Kien Giang, and employs fixed-effect method in supply response function model. Obtained estimates indicate adaptive expectation hypothesis is the best fit the data. It also proves that in both short run and long run, the expected prices have significant influence to the supply response of tiger shrimp farmers. Particularly, the response of area to farm-gate prices, input farm-gate price, and competitive prices are all elastic, showing the importance of these factors in the supply function of black tiger shrimp farming in Mekong Delta.

Key words: black tiger shrimp, Nerlove model, supply response, price elasticity.
