specialize in their strengths and they manage to get four problems of algebra and four problems of statistics solved in one day. When individuals trade, using their comparative advantage their combined production possibility curve shifts out. (Colander) The above example gives a visual sense of the power of markets to make people better off. Markets allow people to trade, to utilize their comparative advantage and there by to improve society’s combined production possibility curve.
