	Tutor2u - Income Elasticity of Demand
		Income elasticity of demand measures the relationship between a change in quantity demanded and a change in income.
		For example if we find that the income elasticity of demand for cigarettes is -0.3, then a 5% fall in the average real incomes of consumers might lead to a 1.5% fall in the total demand for cigarettes (ceteris paribus).
		Consider the income elasticity of demand for flat-screen colour televisions as the market for plasma screens develops and the income elasticity of demand for TV services provided through satellite dishes set against the growing availability and falling cost (in nominal and real terms) and integrated digital televisions.

	OECD Glossary of Statistical Terms - Income elasticity of demand
		The Income elasticity of demand is the quantity demanded of a particular product depends not only on its own price (see elasticity of demand) and on the price of other related products (see cross price elasticity of demand), but also on other factors such as income.
		The measures of income elasticity of demand may be either positive or negative numbers and these have been used to classify products into "normal" or "inferior goods" or into "necessities" or "luxuries".
		Margarine has in past studies been found to have a negative income elasticity of demand indicating that as family income increases, its consumption decreases possibly due to substitution of butter.

	Economics Interactive Tutorial: Elasticity II
		The elasticity of Q with respect to P is the responsiveness of Q to changes in P. Q is the quantity demanded.
		The elasticity of Q with respect to P is the percentage change in Q divided by the corresponding percentage change in P. For example, if the price of something goes up by 1% and sales fall by 2%, the elasticity of quantity demanded with respect to price is -2%/1% = -2.
		Elastic demand typically happens when you are a small player in a big market, and there's a going market price.

	Income elasticity of demand (Site not responding. Last check: )
		In economics, the income elasticity of demand measures the responsiveness of the quantity demanded of a good to the Income of the people demanding the good.
		A zero Income elasticity of demand is an increase in Income without leading to a change in the quantity demanded of a good.
		Many necessities have an Income elasticity of demand between zero and one: expenditure on these goods may increase with income, but not as fast as Income does, so the proportion of expenditure on these goods falls as Income rises.

	Elasticity
		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.
		Goods with a positive income elasticity are normal goods; if the income elasticity is not simply positive but is greater than one the good is classified as a luxury good.

		And if the demand for the item should actually shrink with income growth, the value of the ratio would be negative, implying that the item is an inferior good in that particular market.
		Assuming that a target market is enjoying income growth at some rate, those items with positive income elasticities of demand which are also greater than 1 should be promoted in the target market.

	Chapter Notes
		This is because, as we move along the demand curve, the percent change in price is equal to the percent change in quantity - therefore, the elasticity is equal to 1.
		The demand curve has become steeper, which means that the change in quantity (along the horizontal axis of the graph) is smaller.
		For a horizontal demand curve, the price elasticity of demand is infinitely large (because to calculate elasticity you have to divide by zero).

		The income elasticity of demand measures the percentage change in demand caused by a percentage change in income.

		A downward sloping demand curve can be divided into three parts by the price elasticity of demand: the elastic region, the unit-elastic point, and the inelastic region.

	Elasticity (economics) - Wikipedia, the free encyclopedia
		Elasticity is the slope of a curve on a loglog graph only, not on a regular graph (taking into account whether the independent variable is on the horizontal or the vertical axis).
		Elasticity is an important concept in understanding the incidence of indirect taxation, marginal concepts as they relate to the theory of the firm, distribution of wealth and different types of goods as they relate to the theory of consumer choice and the Lagrange multiplier.
		Elasticity is also crucially important in any discussion of welfare distribution: in particular consumer surplus, producer surplus, or government surplus.

		When the price elasticity of demand is more negative than -1.0, that portion of the demand curve is said to be ___________.
		Because quantity demanded is larger at the upper end of the demand curve than at the lower end, a 50-unit increase in quantity demanded represents a smaller percentage change at the upper end than at the lower end.

	Wealth elasticity of demand - Wikipedia, the free encyclopedia
		Wealth elasticity of demand in microeconomics is the proportional change in the consumption of a good caused by unanticipated net wealth changes (as opposed to changes in personnel income).
		This is analogous to the definition of the income effect from the income elasticity of demand, or the substitution effect from the price elasticity.
		The elasticity has important implications for monetary policy: Investments with a fixed yield (such as a bond paying coupons at 5%) will increase in net present value as interest rates fall.

	Price Elasticity of Demand
		In the extreme case of near infinite elasticity, the demand curve would be nearly horizontal, meaning than the quantity demanded is extremely sensitive to changes 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.
		Time period considered: elasticity tends to be greater over the long run because consumers have more time to adjust their behavoir to price changes.

	Income Elasticity Of Demand
		The degree to which a demand for a good changes with respect to a change in income depends on whether the good is a necessity or a luxury.
		This is because consumers, instead of buying more of only the necessity, will want to use their increased income to buy more of a luxury.
		During a period of increasing income, demand for luxury products tends to increase at a higher rate than the demand for necessities.
