• Suppose that the world is divided into two sovereign countries, Country 1 and Country 2. There are two commodities in the world: cloth and food. Each country has a fixed endowment 150 units of labor and each can produce both the commodities but they differ in terms of their prevailing technologies. Country 1 can make a unit of cloth using 2 units of labor and a unit of food by using 1 unit of labor. Country 2 can make a unit of food using 2 units of labor and a unit of cloth by using 1 unit of labor. Draw the production possibility frontier of country 1. Draw the production possibility frontier of country 2. Draw their joint production possibility frontier. What should each country produce if they are allowed to trade with one another? What do you think should be the exchange rate between food and cloth in an open economy situation? (Limit: 2 pages; Ideally, between 1 – 1.5 pages)
