Household Demand for Convenience and Nonconvenience Foods
用近乎理想需求系统分析美国家庭对便利与非便利食品的需求，发现预算份额对价格比对总支出更敏感，且便利食品主要被白人、家庭管理者在35岁以下且在职的家庭使用。
Abstract A variation of the Almost Ideal Demand System was employed to determine the impacts of total food expenditure, income, food prices, household size, and demographic variables on household demand for convenience and nonconveninece foods in the United States. The budget shares are generally more responsive to prices than to real total expenditure. Additionally, the quantities demanded of convenience and nonconvenience foods are generally more sensitive to changes in income and own‐prices than to changes in cross‐prices. With regard to demographic variates, primary users of convenience foods are white households with employed household managers less than 35 years of age.
