In this study, we provide estimates of An Almost Ideal Demand System (AIDS), as reflected in the demand analysis for Jordan: the free, the homogeneous, the symmetric, and the restricted AIDS models were estimated. The evaluated total expenditure elasticities indicate that the demand for food and housing is inelastic concerning total expenditure (income), whereas the demand for all the other commodity groups is elastic. The uncompensated own-price elasticities indicate that demand for food and clothing items is inelastic and inelastic for all other commodity groups. One striking result was that the own-price elasticity for food seems to be relatively very large compared to the estimated for other countries. Based on the log-likelihood ratios, homogeneity and symmetry given homogeneity for the whole system were rejected. These findings suggest that the demand for aggregate commodity groups in Jordan is not consistent with the theory of demand
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
