. The United States currently imports all of its coffee. The annual demand for coffee by U.S. consumers is given by the demand curve Qd = 150 − 10P, where Qd is quantity (in millions of pounds) and P is the market price per pound of coffee. Suppose the domestic supply is Qs = 10P −50. The U.S. coffee market is competitive. Suppose that the world price of coffee is $6. Congress is considering a tariff on coffee imports of $2 per pound. (a) Find the producer and consumer surplus if there was no trade. (b) Calculate the consumer and producer surplus after we engage in free trade. (c) If the tariff is imposed calculate the changes to consumer and producer surplus. (d) Other than lower prices, provide two benefits that can occur as a result of free trade.
