-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...

W study three determinants of the levels of price and detailing effort across geographic markets: the withinmarket response to each variable, the nature of interfirm strategic interactions both within that market and across markets. We empirically examine the interactions of Prozac, Zoloft, and Paxil across the United States, the United Kingdom, Germany, France, and Italy. Our results indicate ...

We explore a methodological improvement to the standard dynamic demand model for petrol–a general model which allows for slowly evolving, unobservable habits. If this habit formation model is correct, then standard estimation techniques produce inconsistent estimates. We find price elasticities of -0.13 (short-run) and -0.20 (long-run). Importantly, standard techniques are misleading about the ...

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 ...

BACKGROUND Few studies have examined the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China. OBJECTIVE To estimate the conditional cigarette consumption price elasticity among adult urban smokers in China and to examine the differential responses to cigarette pr...

We analyze the welfare impacts of price discrimination in a two-dimensional spatial differentiation model. Consumer information of varying qualities is available on one dimension which allows firms to price discriminate, and better information leads to more refined price discrimination. We find that as information quality improves, firms’ profits monotonically increase while consumer surplus an...

Incorporating a household’s net sale status into a rearranged Slutsky equation with combined ordinary and endowment income effects, this paper aims to reinterpret the income elasticity of demand in the case of buying and selling and to associate it with types of goods in a novel manner. To this end, the Deaton’s (1989) net benefit ratio (NBR) approach is expressed as the difference between orig...

Recent empirical evidence shows the Law of One Price does not exist in online environment despite the unprecedented amount of price transparency. The failure of Law of One Price has been attributed to search costs, brand loyalty and other kinds of “market frictions” that enable retailers to keep some of their customers even if they don’t charge the lowest price in the market. While the presence...

The price transmission from the international market to the domestic market of tunas was investigated in the present research. For this purpose, the elasticity of substitution between tuna imports with goods produced in Iran (Armington Elasticity) was calculated. Armington elasticity reflects a degree of substitution between commodities produced domestically and those produced abroad. A greater...
