Elasticities Price elasticity of demand (PED) Law of demand tells us that P goes up Q goes down or P goes down and Q goes up. But it doesn’t give us any information about by how much Q changes compared to P. We want to know‚ using the PED‚ whether Q is changing by a lot compared to P‚ by a little bit compared to P or by the same rate as P. If %∆P<%∆Q‚ this good is called relatively elastic. If %∆P>%∆Q‚ this good is called relatively inelastic. If %∆P=%∆Q‚ this good is called unit elastic.
