Spanish Demand for Food Away from Home: Analysis of Panel Data
利用面板数据分析了西班牙家庭外出就餐需求，发现零支出主要源于购买频率低而非经济原因，且不同家庭特征（如教育、年龄、就业）对支出弹性影响显著。
Abstract We analyse the Spanish demand for food away from home (FAFH). A panel dataset is built and appropriate techniques for estimating limited dependent variable models are applied. Results indicate that where there are zero expenditures, these are largely due to infrequency of purchase rather than to abstention, or for economic reasons. Furthermore, important differences appear among households. Households whose head is a highly educated person, male, young and living on a salary in a large town is more likely to purchase FAFH. FAFH expenditure responses to an increase in total per capita expenditure are markedly different depending on the age of the household's head, their employment status and also the size of the resident's town. The lowest elasticity is shown by single‐person households, between 36 and 55 years old, employed and living in large towns, for whom FAFH has become a necessity. On the other hand, FAFH remains a luxury for unemployed couples with one or two children.
