4. Effects of a tariff on international trade The following graph shows the domestic demand for and supply of limes in Guatemala. The world price ( PW ) of limes is $780 per ton and is diplayed as a horizontal black line. Throughout the question, assume that all countries under consideration are small, that is, the amount demanded br any one country does not affect the worid price of limes and that there are no transportation or transaction costs associated with international trade in limet. Also, assume that domestic suppliers will satisfy domestic demand as much as possble before amy exporting or importing takes place. If Guatemala is open to international trade in limes without any restrictions, it will import tons of limes. Suppose the Guatemalan government wants to reduce imports to exactly 40 tons of limes to help domestic produxers. A tariff of perton will achieve this. A tarif set at this level would raise in revenue for the Guatemalan government
