8. Conclusion Conclusion: Using the four extremes of elasticity it is now possible to discuss the effects of putting a tax on any particular product with respect to: 1. Incidence: the more __________ is demand and the more _________ is supply the higher the incidence of a tax on consumers. The more elastic is demand and the more inelastic is supply the higher is the incidence of a tax on producers. t 2. Government revenue: this will be greater the lower the elasticity of demand and the lower the elasticity of supply. 3. Resource allocation: will be most affected the higher is the elasticity of demand and the higher the elasticity of supply.
