Abstract: A five-equation demand model of the U.S. shrimp market was estimated using annual data for the period from 1950 to 1968. Prices, consumption, and ending stocks were the jointly determired variables; predetermined variables were shrimp supplies and consumer income. Exvessel price variations resulted largely from variations in domestic landings. Imports reduced the general level of ex-vessel prices but did not contribute substantially to price variability except in isolated instances. Large price drop occurred during periods of recession when increases in demand were slowed and stock began to build, while landings and imports increased substantially over the previous year.
