Demand Analysis of Fresh and Frozen Finfish and Shellfish in the United States
分析了美国家庭对五种鱼类和三种贝类的消费支出，发现自身价格、家庭收入、家庭规模等因素影响支出，且家庭规模比收入对支出的影响更敏感。
Abstract Household expenditures for at‐home consumption on three species of shellfish and five species of finfish were analyzed. Factors explaining the variation of expenditures on seafood commodities were own price, household income, coupon value, household size, geographic region, urbanization, race, and seasonality. Own‐price elasticities ranged from −0.45 (flounder/sole) to −1.13 (oysters). Expenditures on fishery products were more sensitive to changes in household size than to changes in household income. Cross‐price effects of red meat and poultry were not statistically significant. For comparison purposes, estimates of own‐price, income, and household size elasticities from the literature were made with this set of elasticities.
