Opp Cost and Comp Advantage

Here are some hypothetical numbers used to illustrate the ideas of trade-offs, specialization, and comparative advantage. Assume Sri Lanka, using all her resources efficiently, can produce either 1,000 bags of rice OR 3,000 bags of tea. Let’s also assume that, using all her resources efficiently, Kenya can produce either 1,000 bags of rice OR 1,000 bags of tea. Further, assume that the countries have similar resource endowments and that, initially, they are not trading with each other. Therefore, each of the countries has to produce both rice and tea for its citizens. Suppose that, in the no-trade situation, Sri Lanka was consuming 400 bags of rice and 1,800 bags of tea, and in the no-trade situation, Kenya was consuming 500 bags of rice and 500 bags of tea.
