need some help thank you !!

1. Welfare effects of free trade in an exporting country Consider the Kenyan market for lemons. The following graph shows the domestic demand and domestic supply curves for lemons in Kenya. Suppose Kenya's government currently does not allow international trade in lemons. Use the black point (plus symbol) to indicate the equilibrium price of a tonne of lemons and the equilibrium quantity of lemons in Kenya in the absence of international trade. Then, use the green point (triangle symbol) to shade the area representing consumer surplus in equilibrium. Finally, use the purple point (diamond symbol) to shade the area representing producer surplus in equilibrium.1100 Domestic Demand Domestic Supply 1000 Equilibrium without Trade 900 A 800 Consumer Surplus 700 O PRICE (Dollars per tonne) 600 500 Producer Surplus 400 300 200 100 0 35 70 105 140 175 210 245 280 315 350 QUANTITY (Tonnes of lemons)Based on the previous graph, total surplus in the absence of international trade is $87,500 The following graph shows the same domestic demand and supply curves for lemons in Kenya. Suppose that the Kenyan government changes its international trade policy to allow free trade in lemons. The horizontal black line (Pw ) represents the world price of lemons at $800 per tonne. Assume that Kenya's entry into the world market for lemons has no effect on the world price and there are no transportation or transaction costs associated with international trade in lemons. Also assume that domestic suppliers will satisfy domestic demand as much as possible before any exporting or importing takes place. Use the green point (triangle symbol) to shade consumer surplus, and then use the purple point (diamond symbol) to shade producer surplus.1100 Domestic Demand Domestic Supply A 1000 Consumer Surplus 900 800 PW 700 Producer Surplus PRICE (Dollars per tonne) 600 500 400 300 200 100 0 35 70 105 140 175 210 245 280 315 350 QUANTITY (Tonnes of lemons) When Kenya allows free trade of lemons, the price of a tonne of lemons in Kenya will be $800. At this price, 105 tonnes of lemons will be demanded in Kenya, and 245 tonnes will be supplied by domestic suppliers. Therefore, Kenya will export 140 tonnes of lemons.Using the information from the previous tasks, complete the following table to analyze the welfare effect of allowing free trade. Without Free Trade With Free Trade (Dollars) (Dollars) Consumer Surplus Producer Surplus When Kenya allows free trade, the country's consumer surplus decreases * by $ , and producer surplus increases ~ by $ . So, the net effect of international trade on Kenya's total surplus is a gain * of $490 Domestic Demand Domestic Supply 460 World Price Plus Tariff 430 400 370 CS PRICE (Dollars per tonne) 340 310 PS 280 PW 250 Government Revenue 220 190 0 20 40 60 80 100 120 140 160 180 200 DWL QUANTITY (Tonnes of wheat)Complete the following table to summarize your resorts from the previous two graphs. Under Free Trade Under a Tariff (Dollars) (Dollars) Consumer Surplus Producer Surplus Government Revenue :1 Based on your analysis, as a result of the tariff, Bollvia's consumer surplus V by $ , producer surplus v by s , and the government collects $ in revenue. Therefore, the net welfare effect is a V of 4. Effects of a tariff on international trade The following graph shows the domestic supply of and demand for oranges in Zambia. The world price (Pw ) of oranges is $760 per tonne and is represented by the horizontal black line. Throughout the question, assume that the amount demanded by any one country does not affect the world price of oranges and that there are no transportation or transaction costs associated with international trade in oranges. Also, assume that domestic suppliers will satisfy domestic demand as much as possible before any exporting or importing takes place.1080 Domestic Demand Domestic Supply 1040 1000 960 920 PRICE (Dollars per tonne) 840 800 W 760 720 680 0 30 60 0 120 150 180 210 240 270 300 QUANTITY (Tonnes of oranges) If Zambia is open to international trade in oranges without any restrictions, it will import tonnes of oranges. Suppose the Zambian government wants to reduce imports to exactly 60 tonnes of oranges to help domestic producers. A tariff of $ per tonne will achieve this. A tariff set at this level would raise $ in revenue for the Zambian government
