Conventional Milk

Consumers in the U.S. increasingly prefer plant-based milk alternative beverages (abbreviated “plant milk”) to conventional milk. This study is motivated by the need to take into consideration varied nutritional and qualitative attributes in plant milk to examine consumers’ purchasing behavior and estimate demand elasticities which are achieved by a new approach combing hedonic pricing model with Barten’s synthetic demand system. The method of estimation is enlightened from the common practice of companies differentiating their products in multidimensions in terms of attributes. A research dataset was uniquely created by associating the products’ purchase data from Nielsen Homescan dataset with exclusive first-hand nutritional data. Estimations began with creating a multidimensional hedonic attribute space based on the qualitative information of different types of plant milk and conventional milk available to consumers and then calculating the hedonic distances by Euclidean distance measurement to reparametrize Barten’s synthetic demand system. Estimation results showed that the highest own-price elasticity pertained to soy milk which was −0.25. Three plant milk types had inelastic demand. Soy milk exerted substituting effects on all types of conventional milk products and vice versa. Soy milk, rice milk and almond milk entertained complementary relationships between each other and four types of conventional milk were strong substitutes within the group.

The paper analyzes the demand of main consumption groups in Egypt to extraction parameter estimates of these groups. The consumer demand studies in Egypt are limited especially in addressing the demand groups. This paper considers elasticities of main consumption groups by estimating the linear approximation almost ideal demand system (LA/AIDS) using cross-sectional data from the Egyptian 2012/2013 household income and expenditure and consumption survey (HIECS). The estimated model was done by the Iterated Seemingly Unrelated Regressions (ISUR) estimator with the homogeneity and symmetry constraints imposed. The principal findings indicated that the Marshallian own-price elasticities were negative for main groups except for health, transport, and restaurants and hotels while the signs of expenditure elasticities were positive that meaning all groups are normal or luxury groups.

General Demand

This article provides an overview of the literature on consumer and demand system analysis with emphasis on complete food demand systems. It presents theoretical foundations, constrained utility maximization, properties, and general demand restrictions. It discusses dual functions, including the expenditure function, the indirect utility function, and the distance function. The first three dual approaches are standard tools of the applied demand system analyst. Then it introduces the issue of welfare effects and integrability along with separability and aggregation. The article also provides a review of functional forms and covers econometric issues that include estimation, inference and hypothesis testing, specification tests, and other empirical issues. Models of the almost ideal demand and inverse systems as well as some additional hypothesis tests and inferences regarding model performance are estimated and reported.
