We examine how gasoline price volatility impacts consumers’ price elasticity of demand for gasoline. Results show that volatility in prices decreases consumer demand for gasoline in the intermediate run. We also find that consumers appear to be less elastic in response to changes in gasoline price when gasoline price volatility is medium or high, compared to when it is low. Moreover, we find th...

Today, a new infrastructure provisioning approach called Cloud Elasticity is evolving, covering three dimensions of elasticity: resource, cost, and quality. Recently, Cloud Elasticity has been utilized for Business Process Enactment in the Cloud as the involved services face highly volatile demand levels. Through treating the three dimensions equally, so-called Elastic (Business) Processes can ...

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...

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...

a model of the iranian wheat market is specified and fitted to data from 1981-2008. severaldiagnostic tests were employed in the analysis to determine the specification of the model. despitethe simplicity of the model and data problems, an examination of the econometric model leads toseveral conclusions with possible important policy implications for the wheat economy in iran.the general result...

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 ...
