Food Consumption in Pakistan: Application of Linear Approximate Almost Ideal Demand System

The Almost Ideal Demand System : A Comparison and Application to Food Groups

\ 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...

Consumer behavior in rural areas of iran : an almost ideal demand system analysis

Almost multiplicative linear functionals and approximate spectrum

We define a new type of spectrum, called δ-approximate spectrum, of an element a in a complex unital Banach algebra A and show that the δ-approximate spectrum σ_δ (a) of a is compact. The relation between the δ-approximate spectrum and the usual spectrum is investigated. Also an analogue of the classical Gleason-Kahane-Zelazko theorem is established: For each ε>0, there is δ>0 such that if ϕ is...

Accounting for Trends in the Almost Ideal Demand System

Flexible functional forms of indirect utility and expenditure functions are frequently used in approximating the behavior of utility maximizing consumers to arrive at demand systems that can be easily estimated. A common nding in time series estimations of the Almost Ideal Demand System is strong persistence in the estimated residuals. This paper suggests two explanations for this result. First...
