Question

Consider the following trade situation:

The U.S. demand for imports of tomatoes from Mexico is Q_D = 24 - P

The supply of tomatoes to the United States from Mexico is Q_S = 6 + P

The units are million boxes and U.S. dollars per box

One U.S. dollar buys 10 Mexican pesos

Draw a graph showing clearly the quantity of US imports of tomatoes from Mexico and their price in dollars.

There is free trade in tomatoes (no tariffs or quotas on imports from Mexico), but the Mexican peso increases in value against the dollar, so that one dollar only buys 5 pesos. The cost of tomatoes for the U.S. consumer is now double what it was in the base case for each quantity imported. In the table below show the quantity of imports supplied at various prices before (from the equation above) and after the change in the currency values.

Quantity of tomatoes	U.S. price before currency change	Mexican price	U.S. price after curreny change

Draw a graph of the problem in U.S. dollars, showing clearly the price that U.S. importers (the buyers) pay and the quantity of trade that will occur.
