Markets promote efficiency through competition and the division of labor—the specialization that allows people and economies to focus on what they do best. Global markets offer greater opportunity for people to tap into more and larger markets around the world. It means that they can have access to more capital flows, technology, cheaper imports, and larger export markets. But markets do not necessarily ensure that the benefits of increased efficiency are shared by all. Countries must be prepared to embrace the policies needed, and in the case of the poorest countries may need the support of the international community as they do so.
