Spanish Household Demand for Seafood
研究了西班牙家庭在新鲜和加工海鲜产品上的消费行为，发现收入和人口变量显著影响参与和支出，且女性时间价值影响加工海鲜支出。
Seafood is an important food commodity in Spain, the second largest consuming nation of seafood in the world. Today, several changes in demographics, socioeconomic factors, and lifestyle changes have affected demand for seafood products. Double‐hurdle models allow an examination of Spanish household expenditures on these products and explicitly account for the value of women's time. The empirical evidence shows that the set of statistically significant factors in the participation and expenditure equations is not the same for fresh and processed seafood goods. Income and household demographic variables are important determinants of both participation and expenditures on seafood products. In addition, the value of women's time affects expenditures on processed products, which include frozen, cured, and canned seafood goods.
