	Price Elasticity of Demand
		The economic measure of this response is the price elasticity of demand.
		Price elasticity of demand is calculated by dividing the proportionate change in quantity demanded by the proportionate change in price.
		The price elasticity of demand can be applied to a variety of problems in which one wants to know the expected change in quantity demanded or revenue given a contemplated change in price.

	Elasticity Outline
		Elasticity is a measure of sensitivity of change in one variable as a result of the change in another variable.
		The determinants of the price elasticity of demand are: (a) number and availability of close substitutes; (b) Proportion of consumers' budgets; (c) Length of the period; (d) Whether the good is a necessity or a luxury; and (e) How narrowly or broadly the good is defined.
		Price elasticity of demand can be classified as: (a) elastic (coefficient is greater than 1); (b) inelastic (coefficient is less than 1(; (c) unit or unitary elastic (coefficient is equal to 1); (d) perfectly elastic (coefficient is undefined or infinity); and (e) perfectly inelastic (coefficient is equal to zero).

	Tutor2u - Price Elasticity of Demand
		Demand is responsive to a change in price.
		The percentage change in quantity demanded is equal to the percentage change in price.
		For example, after the two world oil price shocks of the 1970s - the "response" to higher oil prices was modest in the immediate period after price increases, but as time passed, people found ways to consume less petroleum and other oil products.

	ESTIMATION OF THE RESIDENTIAL PRICE ELASTICITY OF DEMAND FOR WATER BY MEANS OF A CONTINGENT VALUATION APPROACH
		The need for estimating the price elasticity of demand for water in South Africa was emphasised by representatives of the World Bank during a meeting with the Department of Water Affairs and Forestry to discuss water tariffs during November 1996.
		In studying the literature on determining the price elasticity of demand for water as a consequence of price increases, the researchers undertaking the WRC study found that econometric analysis was the common approach adopted.
		For example the average short-run price elasticity of demand for water is -0,21, whilst in the long-run, the average figure is -0.6.

	Teacher's Corner: Elasticity and Its Expansion: Library of Economics and Liberty
		Marshall was the first economist to explicitly define price elasticity of demand and formalize the mathematical derivation of elasticities, but he was not the first to consider the relationship between changes in prices and changes in quantities demanded.
		If the price of a necessity were to rise in consequence of taxation, the quantity demanded would not fall as much because fewer people are able to reduce their consumption of necessities.
		Elasticity in general, and price elasticity of demand in particular, allow economic agents to get a firmer grasp of the actions they should take to improve the economic outcomes that affect them.

	The Concept of Elasticity
		Price elasticity of demand: how sensitive is the quantity demanded to a change in the price of the good.
		Price elasticity of supply: how sensitive is the quantity supplied to a change in the price of the good.
		Elastic demand means that the quantity demanded is sensitive to the price.

		The result is negative because an increase in price (a positive number) leads to a decrease in purchases (a negative number).
		The price elasticity of demand for meat will be lower than the price elasticity of pork, and the price elasticity for soft drinks will be less elastic than the price elasticity for colas, which in turn will be less elastic than the price elasticity for Pepsi.
		When the price of gasoline rose rapidly in the late 1970s as a result of the OPEC cartel, the only adjustment consumers could initially make was to drive less.

	Price Elasticity of Demand (Site not responding. Last check: 2007-11-05)
		Because the demand curve is downward sloping the change in q is in the opposite direction from the change in p.
		If the magnitude of elasticity is less than one then the percentage change in quantity is smaller than the percentage change in price and expenditure will move in the same direction as price.
		In this case the price elasticity of demand is -15/10 or -1.5.

		The demand and supply function are traditionally shown (since Alfred Marshall) with the price on the y axis and the quantity on the x axis.
		Elasticity is the measure of the relative change in quantity compared to the relative change in price.
		Elasticity measures compare the percentage change in price and quantity and hence eliminates comparisons that may be misleading when done with slopes.

	Price Elasticity of Demand [Mackinac Center for Public Policy] (Site not responding. Last check: 2007-11-05)
		The most commonly used measure of consumers' sensitivity to price is known as "price elasticity of demand." It is simply the proportionate change in demand given a change in price.
		A good with a price elasticity stronger than negative one is said to be "elastic;" goods with price elasticities smaller (closer to zero) than negative one are said to be "inelastic." Goods that are more essential to everyday living, and that have fewer substitutes, typically have lower elasticities; staple foods are a good example.
		For example, the demand for automobiles would, in the short term, be somewhat elastic, as the purchase of a new vehicle can often be delayed.

	Elasticity
		The usual meaning is the price elasticity of demand, or the responsiveness of the quantity demanded to price.
		We speak of an elastic demand -- one which is very responsive to price, and which would result in a relatively flat demand curve; and of an inelastic demand -- one not very responsive to price.
		The coefficient of elasticity or COE for short is the measure of elasticity.

	Price Elasticity of Demand
		The price elasticity of demand measures the responsiveness of quantity demanded to a change in price, with all other factors held constant.
		Time period considered: elasticity tends to be greater over the long run because consumers have more time to adjust their behavoir.

	How much will price changes effect stock trading?
		If the price elasticity is exactly equal to one, then that means that the stock is unit elastic, but that result is relatively rare.
		For example, program trading will lower the price elasticity of a market due to the fact that most program trading will occur regardless of what happens to the price of stock in the mean time.
		Price elasticity is an economics term that refers to the way that price changes of stock can affect the demand for that stock.

	Demand Elasticity
		In fact, when the economist wants to know how "price elastic" the demand for apples is, all he really wants to know is how the demand for apples "responds" to a change in the price of apples.
		However, this is where we come to a slight perversion in economics: since the price elasticity of demand is consistently negative, economists forget about the negative sign and pretend that it is consistently positive.
		If the demand for pizzas is responsive to changes in price, when the price falls, people will increase the number of pizza they demand.

	Cross Price and Elasticity of Demand
		If the quantity demanded remains constant when the price changes, then the elasticity of demand is zero and demand is said to be perfectly inelastic.
		On other hand if the percentage of quantity demanded is less then the percentage change in price, then the magnitude of the elasticity of demand is between zero and one and demand is said to be inelastic.
		Elasticity of demand is usually influenced by three crucial factors and these main factors are: · The closeness of substitutes · The proportion of income spent on the good · The time elapsed since a price change The closer the substitutes for a good or services, the more elastic is the demand for it.

	E111RChap7solutions-Demand and Elasticity
		This is the definition of inelastic demand in which the numerator (% change in quantity) is less than the denominator (% change in price) so that the absolute value of the ratio (price elasticity of demand) is less than 1.
		If the price is doubled (from $10 to $20) and quantity demanded is cut exactly in half as a result, then total revenue (which is price times quantity) will remain constant.
		Therefore, increasing price by $15 (from $20 to $35) results in quantity demanded decreasing by 3 units (from 6 units to 3 units).

	Principles of Microeconomics: Section 4 Introduction
		The price elasticity of demand measures the change in the quantity demanded for a good in response to a change in price.
		Changes are measured in percentage terms and the price elasticity of demand equals the percentage change in quantity demand divided by the percentage change in price.
		In addition, as elasticity decreases, a greater proportion of the tax burden is passed on to the consumer and less is incurred by the producer.

	SAS/ETS Examples -- Calculating Price Elasticity of Demand
		The price elasticity of demand is defined as the percentage change in quantity demanded for some good with respect to a one percent change in the price of the good.
		Price elasticity greater than one is called price elastic, and price elasticity less than one is called price inelastic.
		For example, prices of some other closely related goods may have a significant effect on the quantity demanded for beef; hence, they may also enter the right-hand side of the demand equation.
