Supply and Demand Kimberly Jo DeVoy Western Governor’s University Supply and Demand A. Elasticity of demand represented as “Ed” is defined as a “measure of the response of a consumer to a change in price on the quantity demanded of a good” (McConnell, 2012). Determinants for elasticity of demand would include the substitutability of a good, proportion of a consumer 's income spent on a good, the nature of the necessity of a good and the time a purchase is under consideration by the consumer. Furthermore, elasticity of demand is calculated with this formula: Ed = percentage change in quantity demanded of product X percentage change in price of product X When price elasticity of demand is elastic, the coefficient will be greater than one. When a percent price change occurs quantity demanded responds strongly there will be a large change in quantities consumers purchase. There is price sensitive in this scenario. If price elasticity of demanded is inelastic the coefficient will be less than one. When a percent price change occurs quantity demanded does not respond strongly then there is a slight change in quantities consumers will purchase. There a weak price sensitive in this scenario. Lastly, if price elasticity of demanded is unit elastic the coefficient will be equal to one. Whenever there is a percent change in price there is an equally matched percent change in quantity demanded. This scenario is rare. B. Cross-price elasticity represented as “Exy” is
