The household production approach is used to characterize the household's preference toward nutrients in food consumption. Elasticities of substitution and Hicksian price elasticities are estimated, price- and expenditure-nutrient elasticities are calculated. Results show that protein is the...

Demand relationships for two closely related products -- grapefruit juice and grapefruit-juice cocktail -- were estimated from grocery-store scanner data to analyze the contention that consumer confusion exists between the two products. Results suggest confusion may exist, with grapefruit-juice...

An extension of the differential demand system model is developed that allows the demand system’s income and price responses to vary with income level. The model’s income flexibility and marginal propensities to consume (MPCs) out of income are made functions of real income measured by the...

Two levels version of the Rotterdam demand systems were developed using utility theory with additional nutrient variables. Income, price, and nutrient demand elasticities were estimated. Results show that some nutrients are important factors in determining the demand for food items.

Seven systems of Engel curves for expenditures on ten commodity groups were estimated using Taiwanese household expenditure data for the period from 1996 through 1998. Results show that the estimated expenditure elasticities are insensitive to the choice of functional forms.

The issue of identification of the parameter α0 in the price index of the Almost Ideal Demand System (AIDS) is examined. In nearly all empirical studies, the model’s likelihood function has been extremely flat in α0, and this parameter has not been able to be estimated. Assumed values are...

A demand model is developed to examine the impacts on orange juice prices resulting from elimination or reduction of the tariffs on orange juice imposed by the United States, European Union, and Japan. An empirical analysis suggests that elimination of the U.S. tariff by itself would decrease...

This study examines imposing and testing restrictions on preference variables in the Rotterdam model through the impacts of these variables on marginal utilities. An empirical analysis of the impact of a female labor force participation variable in a Rotterdam demand system for fresh fruit...

This study adopted the scaling approach to examine the impacts of inventories on tuna auction prices in Japan using the Rotterdam inverse demand system. The inclusion of two inventory variables in the model only increases the number of parameters by two. Results indicate that frozen tunas are...

Nielsen ScanTrack data were used to study how income and prices influenced consumer juice beverage demand in the United States during the period from 1988-89 through 1991-92. Alternative differential demand models combining the features of the Rotterdam model and the almost ideal demand system...
