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...

We derive a structural model of firm behavior that is composed of the Generalized Quadratic Almost Ideal Demand System to represent both consumers' milk preferences and firm profit maximization conditions that allow for a range of competitive scenarios. The importance of this specification is...

This article explores the issue of price and expenditure endogeneity in empirical demand analysis. The analysis focuses on the U.S. carbonated soft drink market. We test the null hypothesis that price and expenditures are exogenous in the demand for carbonated soft drinks. Using an almost ideal...

The purchase dynamics of a subset of food fats and oils are investigated using event-history analysis applied to a panel of U.S. households. The consumer behavior examined is the switching between purchases of butter, margarine, and butter/margarine blends across purchase occasions. We find that...
