abstract increase in aquatics demand is one of the major goals for production policies. hence analysis of demand structure and aquatics consumption patterns is very applicative and useful for policy makers. using the almost ideal demand system (a.i.d.s), the demand function for types of aquatics and chicken meat in urban and rural societies in kerman city were estimated. applying time series da...

abstract: on december 2010, the government of iran ended the decades-long subsidy program for bread and energy products and launched the targeted subsidy reform program that considerably raised prices of food products. the objective of the study was to measure welfare impacts of food price changes on iranian urban households between two survey data of 2009/10 and 2011/12 which were taken from i...

The housing market exhibits a puzzling phenomenon that transaction volume and prices are strongly positively correlated. This paper develops and estimates a dynamic search-matching model to study the impact of the unemployment rate on the housing market in the presence of the thick market effect. Our analysis shows that an increase in the unemployment reduces the number of buyers, weakens the h...

Objective Estimate price elasticity of demand for cigarettes and alcohol in Ecuador using cross-sectional data from the National Survey of Urban and Rural Household Income and Expenditures (ENIGHUR is the acronym in Spanish) 2011-2012. Methods ENIGHUR 2011-2012 data were used with Deaton's (1, 2) methodology to estimate price elasticity of demand for cigarettes and alcohol with expenditure an...

Understanding how consumers respond to electricity prices is essential for predicting the effects of climate change policy and other policies that target electricity markets. To date, studies of long-run electricity demand have relied on price changes that are transient or endogenous, and none have utilized experimental or quasi-experimental variation. We study the dynamics of residential elect...

This paper simulates a pool-based electricity market and identifies equilibrium patterns. A multiperiod framework that requires the use of continuous and binary variables is considered. Producers can be either price-takers or price-makers, although price-makers and their behavior characterize the market. The elasticity of the loads is modeled through piecewise constant pricedemand curves. The m...

The aim of this study was to evaluate sound and decayed wood of Iranianbeech (Fagus orientalis) with a nondestructive stress wave method. Wood samples,with dimensions of 9 by 19 by 200 mm were decayed in laboratory soil-bed tests,based on European pre-standard ENV-807. The decay was evaluated by measuringbending dynamic modulus of elasticity (MOEd) and longitudinal dynamicmodulus of elasticity ...

In this study, the pricing problem of a transportation service provider company is considered. Our goal is to find optimal prices by using probabilistic dynamic programming. A fuzzy IF-THEN-rule based system is used to identify the demand levels under different prices and other characteristics of the journey. The results obtained by optimal price policies show that the revenue increases by appl...
