More specifically, it is the percentage change in quantity demanded in response to a one percent change in price when all other <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/www.boundless.com\/economics\/definition\/determinants\">determinants<\/a> of demand are held constant.\n<\/p>\n<p>The formula for the coefficient of PED is:\n<\/p>\n<p>PED =&nbsp;% change in quantity demanded \/&nbsp;% change in price\n<\/p>\n<p>The law of demand states that there is an inverse relationship between price and demand for a good. As a result, the PED coefficient is almost always negative. However, economists tend to ignore the sign in everyday use. Only goods that do not conform to the law of demand, such as Veblen and <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/www.boundless.com\/economics\/definition\/giffen-good\">Giffen goods<\/a>, have a positive PED.\n<\/p>\n<p>The numerical values for the PED coefficient could range from zero to infinity. In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): that is, changes in price have a less than proportional effect on the quantity of the good demanded. The demand for a good is said to be elastic (or relatively elastic) when its PED is greater than one. In this case, changes in price have a more than proportional effect on the quantity of a good demanded.\n<\/p>\n<p>A PED coefficient equal to one indicates demand that is unit elastic; any change in price leads to an exactly proportional change in demand (i.e. a 1% reduction in demand would lead to a 1% reduction in price).\n<\/p>\n<p>A PED coefficient equal to zero indicates perfectly inelastic demand. This means that demand for a good does not change in response to price.\n<\/p>\n<h3><span class=\"mw-headline\" id=\"Perfectly_inelastic_demand\">Perfectly inelastic demand<\/span><\/h3>\n<div class=\"center\">\n<div class=\"floatnone\"><a href=\"https:\/\/wikieducator.org\/File:Elasticity-inelastic.png\" class=\"image\"><img loading=\"lazy\" decoding=\"async\" alt=\"Elasticity-inelastic.png\" src=\"\/\/wikieducator.org\/images\/thumb\/9\/99\/Elasticity-inelastic.png\/400px-Elasticity-inelastic.png\" width=\"400\" height=\"387\" class=\"img-responsive\"><\/a><\/div>\n<\/div>\n<p>When demand is perfectly inelastic, quantity demanded for a good does not change in response to a change in price.\n<\/p>\n<h3><span class=\"mw-headline\" id=\"Perfectly_elastic_demand\">Perfectly elastic demand<\/span><\/h3>\n<div class=\"center\">\n<div class=\"floatnone\"><a href=\"https:\/\/wikieducator.org\/File:Elasticity-elastic.png\" class=\"image\"><img loading=\"lazy\" decoding=\"async\" alt=\"Elasticity-elastic.png\" src=\"\/\/wikieducator.org\/images\/thumb\/8\/89\/Elasticity-elastic.png\/400px-Elasticity-elastic.png\" width=\"400\" height=\"387\" class=\"img-responsive\"><\/a><\/div>\n<\/div>\n<p>Finally, demand is said to be <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/www.boundless.com\/economics\/definition\/perfectly-elastic\">perfectly elastic<\/a> when the PED coefficient is equal to infinity.
