Suppose Sudan is open to free trade in the world market for oranges. Since Sudan is small relative to the international market, the demand for and supply of oranges in Sudan have no impact on the world price. The following graph shows the domestic market for oranges in Sudan. The world price of a ton of oranges is Pw = $350. On the following graph, use the green triangle (triangle symbols) to shade the area representing consumer surplus (CS) when the economy is at the free-trade equilibrium. Then, use the purple triangle (diamond symbols) to shade the area representing producer surplus (PS).
