this paper focuses on the residential sector demand for electricity, natural gas and petroleum products (kerosene, gas oil and lpg) in iran in the context of a popular locally flexible functional forms - “the almost ideal demand system (aids)”. we pay explicit attention to the theoretical regularity conditions of positivity, monotonicity, and curvature. we treat the curvature property as a main...

Households consume animal protein after carbohydrate food is fulfilled, moreover prices are increasing. This study aims to analyze the effect of rising beef on demand. The demand system approach uses Quadratic Almost Ideal Demand System (QUAIDS) model. Estimation parameters using Iterated non-linear Seemingly Unrelated Regression. research data use 2016 National Socio-Economic Survey (Susenas, ...

FOREWORD This study analyzes U.S. consumer budget allocations among 11 agg1 egate commodity groups for the period 1948-78. Also budget allocations among four food groups are analyzed for this same period. Several alternative model specifications are analyzed. Emphasis is given to the Deaton-Muellbauer (1980a) "almost ideal demand system." A dynamic version of their model is developed and quanti...

This paper represents a dynamic specification of the Almost Ideal Demand System (AIDS) based on recent developments on cointegration techniques and error correction models. Based on Greek meat consumption data over the period 1958–1993, it was found that the proposed formulation performs well on both theoretical and statistical grounds, as the theoretical properties of homogeneity and symmetry ...

\ This article presents estimates of the almost Ideal demand system (AIDS) for four food groups_and compares these estimates WI~h the AIDS' own linear approximate versIOn and the linear expenditure system The AIDS IS indirectly nonadditive and has several desirable properties, maklng'lt a Viable demand system for analyzing food commodities Its linear approximate versIOn IS a good first-order ap...
