1) When a tax is imposed on a good, the resulting rise in the equilibrium price is usually less than

6) Suppose the government decides to tax salt. The demand for salt is inelastic and the supply is
quite elastic. Who bears most of the tax incidence and pays most of this tax?
7) Consider the market for dining at Mexican restaurants. Suppose the price elasticity of demand
for Mexican food is 1.23 and the price elasticity of supply is 0.47. If the government imposes a
tax on Mexican food, do consumers or producers pay most of the tax? Why?
