Who are consuming food away from home and where? Results from the Consumer Expenditure Surveys
利用消费者支出调查数据，研究家庭在不同类型餐饮设施（如全服务餐厅、快餐店等）的外出就餐支出，发现经济与人口因素对不同设施和家庭类型的影响存在差异，可为营销策略和政策制定提供参考。
This paper investigates household expenditures on food away from home by type of facility. A system of expenditures at full-service restaurants, fast-food restaurants and other facilities are estimated with a multivariate sample selection procedure, for three types of households by household composition. Statistical significance of error correlations suggests endogeneity of sample selectivity and justifies estimation of the equations in a system to improve statistical efficiency. Differentiated effects of economic and demographic factors are found on expenditures at different facilities and across household types. Findings on the roles of economic and socio-demographic factors can inform marketing strategies and policy deliberations.
