Food Demand in Mexico: An Application of the Amemiya‐Tobin Approach to the Estimation of a Censored Food System
提出一种改进的Amemiya-Tobin框架，用于估计考虑家庭异质性的删失需求系统，并应用于墨西哥城市家庭食品需求分析，确保潜在和观测支出份额的可加性及非负性。
The modeling of micro‐level food demand patterns requires not only allowing for household heterogeneity, but also addressing the problem of censoring. In this article, we present a variation of the Amemiya‐Tobin framework for estimating a censored demand system that allows for household heterogeneity. The unique aspect of our approach is the use of a procedure that ensures the adding up of both latent and observed expenditure shares and also imposes expenditure share nonnegativity. This system is applied to an analysis of food demand based on a random sample of urban Mexican households.
