copus think of elasticities in terms of the slope of the SS and DD curves. The DD curve is negatively sloped and therefore the price elasticity of supply is negative. The SS curve is positively sloped and therefore the price elascticity of supply is positive.
srh011 You mean the price elasticity of demand is negative I think.
gill15 What if its a veblen good or giffen --- they have upward sloping demand curves

then price elasticity would not be negative

farhan92 @gill veblen good - p increase q increases therefore positive elasticity -thats how i see it anyway someone correct me if i am wrong here
jamcarr27 can elasticities not be equal to 0, therefore not negative?
