how is elasticity related to deadweight loss of tax 
the more elastic a good is the greater the potential for deadweight loss because consumers and producers can more easily adjust their behavior in response to tax induced price changes if something is elastic consumers may choose a substitute or avoid the good altogether can tax deadweight loss be completely avoided or is it inherent in taxation achieving a tax system entirely free from deadweight loss is challenging if not impossible taxes always introduce some level of distortion to market activities people are naturally inclined to try and minimize their tax liability when possible so consumer behavior in response to almost any tax may be reasonable to expect even to a small degree
