The following problem analyzes the Zambian market for pears.

The graph below shows the domestic supply and demand curves for pears in Zambia. Assume that Zambia's government does not currently permit international trade in pears.

Use the black point $($plus symbol$)$ to denote the equilibrium price of one ton of pears and the equilibrium quantity of pears in Zambia without international trade. Next, use the green triangle $($triangle symbol$)$ to shade in the area that represents consumer surplus in equilibrium. Finally, use the purple triangle $($diamond symbol$)$ to shade in the area that represents producer surplus in equilibrium.
