The demand curve for tea is Q = 250 10P in Canada. Q is quantity in millions of pounds and P is the market price per pound of tea. Suppose that Canada is importing all of its tea demanded. Foreign producers can ship tea to Canadian distributors at a constant marginal (= average) cost of $8 per pound, and Canadian distributors can in turn distribute tea for a constant $2 per pound. The Canadian tea market is competitive. Government is considering to impose a tariff on tea imports of $2 per pound. a. If the tariff is imposed, how much will consumers pay for a pound of tea? What is the quantity demanded? b. Calculate the lost consumer surplus. c. Calculate the tax revenue collected by the government. d.
