A two-step model with sample selection is applied to panel data of U.S. households to estimate at-home demand for fluid milk and cheese, incorporating advertising expenditures. The model consistently accounts for sample-selection bias, unobserved household heterogeneity, and temporal...

This study develops a unique double-hurdle model of demand for composite food commodities which endogenizes unit values. The model structure allows us to account for the inability to observe such values for non-purchasing households and simultaneously adjusts for quality demand effects reflected...

This study develops a procedure to estimate income distribution effects on market demand. The proposed procedure contains two steps: estimation of the underlying income distribution and estimation of market demand. Empirical findings show that the income distribution effect is a significant...

This study develops an empirical framework that can be used to estimate quality-adjusted price elasticities from cross-sectional data, which are theoretically consistent and comparable to elasticities from time-series data. The new approach shows the importance of properly adjusting for quality...

There is a common perception that healthy food costs more than less healthy food. In this study we use a demand model for diet quality, rather than the quantity of food. Since in our data, total daily cost and diet quality are both calculated from the foods chosen, we account for the fact that...

This study updates existing literature on consumer/household demand for fiber by examining household purchase dynamics for dietary fiber. It uses a dynamic Tobit model that allows past purchase occasions to affect current purchase decisions for fiber in a framework that captures simultaneously...

Kuhn-Tucker approach and its dual have been proposed to the demand system estimation when there are non-negativity bindings. However, empirical researchers have been struggling two decades in applying this method into practice due to: (1) the difficulty in derivation of a coherent econometric...
