Consider the Bangladeshi market for oranges.The following graph shows the domestic demand and domestic supply curves for oranges in Bangladesh. Suppose Bangladesh's government currently does not allow international trade in oranges.

Use the black point (plus symbol) to indicate the equilibrium price of a tonne of oranges and the equilibrium quantity of oranges in Bangladesh 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.

Note: Select and drag a fill area point from the palette to the graph. To fill in regions on the graph, merely drop the fill area point on the desired region.
