Suppose Zambia is open to free trade in the world market for soybeans. Since Zambia is small relative to the international market, the demand for
and supply of soybeans in Zambia have no impact on the world price. The following graph shows the domestic market for soybeans in Zambia. The
world price of a ton of soybeans is P - $250.
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).

Use the following graph to show the effects of the $30 tariff.
Use the black line (plus symbol) to indicate the world price plus the tariff. Then, use the green points (triangle symbols) to show the consumer surplus
with the tariff and the purple triangle (diamond symbols) to show the producer surplus with the tariff. Lastly, use the orange quadrilateral (square
symbols) to shade the area répresenting government revenue received from the tariff and the tan points (rectangle symbols) to shade the areas
representing deadweight loss (DWL) caused by the tariff.
