Trade may not help those most in need.  Aid is linked to need. Trade rewards those who are able and willing to engage in trade. This involves a number of elements – as well as having the rights sorts and quantity of goods and services and being willing to sell at the desired price, a country may need to meet certain other criteria of a purchasing country. For example, that country may make demands in terms of corruption, human rights, political support at the United Nations, or any other of a large number of possible preconditions for a trading partnership. This will suit some countries in the developing world. But for others it will act as a bar to trade. They will therefore not receive the redistribution of wealth that is claimed for the global trading web. In this way, trade can distribute its benefits very unevenly. By contrast, aid can in theory be more evenly distributed and can be targeted against identified need rather than against the ability to compete in a trading marketplace. While aid has not always been targeted effectively and has sometimes been wasted there have been efforts to increase accountability and coordinate aid better such as the Paris Declaration on Aid Effectiveness 1.  1 Development Co-operation Directorate, 'Paris Declaration and Accra Agenda for Action', OECD, Retrieved 2 September 2011 from oecd.org:
