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...

In this paper we assess the relationship between the aggregate income elasticity of aggregate demand and individual income elasticities of demand. We show that the aggregate elasticity is equal to the mean of individual elasticities plus a covariance term. Consequently, the sign of this covariance term determines whether the aggregate elasticity overestimates or underestimates the mean of indiv...

Identifying the factors that influence electricity demand in the continental United States and mathematically characterizing them are important for developing electricity consumption projections. The price elasticity of demand is especially important, since the electricity price effects of policy implementation can be substantial and the demand response to policy-induced changes in prices can s...

The recent push for a federal energy policy that could substantially change electricity prices in the U.S. highlights the need to obtain accurate residential electricity demand estimates. Many electricity demand estimates have been obtained based on the assumption that consumers optimize with respect to known marginal prices, but increasing empirical evidence suggests that consumers are more li...

OBJECTIVE To estimate the price elasticity of cigarette demand among youth in low- and middle-income countries (LMIC). DATA The Global Youth Tobacco Survey was used to obtain data on the smoking behaviour of 315,353 adolescents from 17 LMIC. DESIGN Two-part model of cigarette demand with country fixed effects. The first part estimates the impact of prices on smoking participation while the ...

Hotel demand in large urban markets does respond to changes in income, but that demand is relatively inelastic, according to an analysis of 22 top metropolitan areas in the United States. The analysis, made possible through Smith Travel Research, examined room-night demand for 480 individual hotels from 1989 through 2000 and compared that demand to a set of economic measures, including gross do...
