4. Effects of a tariff on international trade The following graph shows the domestic demand for and supply of limes in New Zealand. The world price (Pw ) of limes is $760 per ton and is displayed as a horizontal black line. Throughout the question, assume that all countries under consideration are small, that is, the amount demanded by any one country does not affect the world price of limes and that there are no transportation or transaction costs associated with international trade in limes. Also, assume that domestic suppliers will satisfy domestic demand as much as possible before any exporting or importing takes place. 1255 Domestic Demand Domestic Supply 1200 1145 1090 1035 980 PRICE (Dollars per ton) 925 870 815 PW 760 705 0 30 60 90 120 150 180 210 240 270 300 QUANTITY (Tons of limes)If New Zealand is open to international trade in limes without any restrictions, it will import tons of limes. Suppose the New Zealand government wants to reduce imports to exactly 120 tons of limes to help domestic producers. A tariff of $ per ton will achieve this. A tariff set at this level would raise $ in revenue for the New Zealand government
