the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

AGGREGATION EFFECTS ON PRICE AND EXPENDITURE ELASTICITIES IN A QUADRATIC ALMOST IDEAL DEMAND SYSTEM Frank T. Denton and Dean C. Mountain

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...

address to increasing demand for wood products and limited domestic resources, wood and wood products imports as one of the easily available and widespread ways in international context, is very important. among the policy on the imported wood market that is evident, apply a tariff and non-tariff barriers. know the reaction importers against the change priced is important to be determined and a...

almost ideal demand system (aids) and rotterdam model have been employed to (by means of seemingly unrelated regression (sur) estimate the function related to milk and dairy products in the urban societies of iran for years 1982 to 2009. cross and cross price elasticities have been evaluated too. results indicated that during the study period, share of milk products in household budget was more...
