Consider two countries (France and the United States) that use labor as an input to produce two goods: wine and cloth. In France, one hour of a worker’s labor can produce either 5 units of cloth or 10 units of wine. In the US, one hour of a worker’s labor can produce either 20 units of cloth or 20 units of wine. The information provided is illustrated as follows: Cloth Wine France 5 10 The United States 20 20 Which of these countries enjoys a comparative advantage in the production of wine?
