Before the North American Free Trade Agreement (NAFTA) gradually eliminated import tariffs on goods, the autarky price of tomatoes in Mexico was below the world price and in the United States was above the world price. Similarly, the autarky price of poultry in Mexico was above the world price and in the United States was below the world price. Draw diagrams with domestic supply and demand curves for each country and each of the two goods. (You will need to draw four diagrams, total.) As a result of NAFTA, the United States now imports tomatoes from Mexico and the United States now exports poultry to Mexico. How would you expect the following groups to be affected?

a. Mexican and U.S. consumers of tomatoes. Illustrate the effect on consumer surplus in your diagram.

b. Mexican and U.S. producers of tomatoes. Illustrate the effect on producer surplus in your diagram.

c. Mexican and U.S. tomato workers. . Mexican and U.S. consumers of poultry. Illustrate the effect on consumer surplus in your diagram.

e. Mexican and U.S. producers of poultry. Illustrate the effect on producer surplus in your diagram.

f. Mexican and U.S. poultry workers.
