5797128990SupplyHow much of a good or service a producer is willing and able to produce at different prices.0
5797128991DemandConsumer willingness and ability to buy products1
5797128992Substitution Effectwhen consumers react to an increase in a good's price by consuming less of that good and more of other goods2
5797128993Income EffectA change in the quantity demanded of a product that results from the change in real income (purchasing power) caused by a change in the product's price.3
5797128994Price Elasticity of DemandA measure of how much the quantity demanded of a good responds to a change in the price of that good, computed as the percentage change in quantity demanded divided by the percentage change in price4
5797128995Law of Demandconsumers buy more of a good when its price decreases and less when its price increases5
5797128996Midpoint Methoda technique for calculating the percent change in which changes in a variable are compared with the average, or midpoint, of the starting and final values.6
5797128997Perfectly InelasticThe case where the quantity demanded is completely unresponsive to price, and the price elasticity of demand equals zero.7
5797128998Perfectly ElasticIn the extreme situation where a small price reduction causes buyers to increase their purchases from zero to all they can obtain. Thus the coefficient is infinite.8
5797128999Unitary Elasticitya demand relationship in which the percentage change in quantity of a product demanded is the same as the percentage change in price in absolute value (a demand elasticity of -1)9
5797129000Total Revenuethe amount paid by buyers and received by sellers of a good, computed as the price of the good times the quantity sold10
5797129001Price Effectinclination of people to buy less of something at higher prices than they would buy at lower prices11
5797129002Quantity Effectafter a price increase, fewer units are sold, which tends to lower revenue12
5797129003ElasticA measure of the responsiveness of quantity demanded or quantity supplied to a change in one of its determinants13
5797129004InelasticDescribes demand that is not very sensitive to price changes14
5797129005Cross-Price Elasticity of DemandEx,y = (%dQd good X) / (%d Price Y). If Ex,y > 0, goods X and Y are substitutes. If Ex,y < 0, goods X and Y are complementary15
5797129006Income Elasticity of DemandIncome Elasticity of Demand: The income elasticity of demand measures the impact of a consumer's income on his or her demand for a product. If the product is a normal good, the income elasticity of demand will be a positive number; if the product is an inferior good, the income elasticity of demand will be a negative number. If income has a strong impact on the consumer's demand for the product, the income elasticity of demand will be a large number in absolute value; if income has a weak impact on the consumer's demand for the product, the income elasticity of demand will be a small number in absolute value.16
5797129007Price Elasticity of SupplyA measure of how much the quantity supplied of a good responds to a change in the price of that good, computed as the percentage change in quantity supplied divided by the percentage change in price17
