1. Welfare effects of free trade in an exporting country
The following problem analyzes the South African market for limes.
The graph below shows the domestic supply and demand curves for limes in South Africa. Assume that South Africa's government does not currently
permit international trade in limes.
Use the black point (plus symbol) to denote the equilibrium price of one ton of limes and the equilibrium quantity of limes in South Africa 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.

The following graph shows the same domestic supply and demand curves for limes in South Africa. Now, suppose that the South African government
changes its stance on international trade, deciding to allow free trade in limes. The horizontal black line (Pw) represents the world price of limes at
$800 per ton. Assume that South Africa's entry into the world market for limes has no effect on the world price and there are no transportation or
transaction costs associated with international trade in limes. Also assume that domestic suppliers will satisfy domestic demand as much possible
before any exporting or importing takes place.

When South Africa adjusts its trade policy to allow free trade of limes, the price of one ton of limes in South Africa becomes $800. At this price,
tons of limes will be demanded in South Africa, and
tons will be supplied by domestic suppliers.
Therefore, South Africa will export
tons of limes.
When South Africa allows free trade, the country's producer surplus
