Assume that several hundred independent farmers in Argentina are the only producers of a rare plant that is used for medicinal purposes around the world. Imagine that you are an economic adviser to the Argentine government. The president asks you to find a way to capture some of the economic rents from the production of this rare plant, so that more profits stay in Argentina. Your job is to design a trade policy that accomplishes the president’s goal.

Explain verbally what your trade policy would be, how it would affect quantity and price in the market, and how it would affect all the players in this market.
