A Nonlinear Expenditure System Using a Linear Logit Specification
提出一个线性Logit家庭支出模型，能自动满足预算约束的加总性质，同时允许恩格尔曲线高度灵活，并可通过线性回归估计系数，适合研究消费模式和人口变量的影响。
Abstract Recent literature on the estimation of models of consumer expenditure patterns indicates that Engel curves are nonlinear and demographic variables are important determinants of demand. A linear logit household expenditures model is presented which automatically displays “adding up” properties derived from the budget constraint while permitting great flexibility in the Engel curves. In addition, homogeneity and symmetry can be imposed and tested, and by a simple transformation the coefficients can be estimated by linear regression. Another advantage of the model is that demographic variables, such as household size and composition, can be introduced without sacrificing the “adding up” properties.
