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...

We introduce a measure of elasticity of stochastic demand, called the elasticity of the lost-sales rate, which offers a unifying perspective on the well-known newsvendor with pricing problem. This new concept provides a framework to characterize structural results for coordinated and uncoordinated pricing and inventory strategies. Concavity and submodularity of the profit function, as well as s...

The separability of consumer desires is a necessary and sufficient condition for multi-stage budgeting and Collectivization is consistent of commodity where costs are allocated between edible groups using price indices and intergroup allocations are made independently of other groups. Given the high share of Citrus fruits, Cucurbits and vegetables types (29/5% percent of household food and beve...

In this journal, Seldon (1986) recently criticized the arc elasticity concept as it is commonly taught in the principles course. In doing so, he resurrected the Lerner (1933a) measure of elasticity, which is based upon the lower values of price and quantity in a price change rather than the average values used in the traditional measure (i.e., the midpoint formula). Seldon argued that the Lerne...

-In this paper, an attempt has been made to establish a market mechanism for primary and secondary frequency regulation services in the restructured power system environment. The concept of elasticity of offer price and elasticity of offer quantity has been proposed. Such a design of offer structure helps the providers to respond to the system requirements based on the market price variations i...

Policymakers in countries around the world are faced with rising health care costs and are debating ways to reform health care to reduce expenditures. Estimates of price elasticity of expenditure are a key component for predicting expenditures under alternative policies. Using unique individual-level data compiled from administrative records from the Chilean private health insurance market, I e...

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...
