The Least Developed Countries are a group of 50 countries that have been identified as least developed in terms of their low GDP, their weak human assets and their high degree of economic vulnerability. The 2007 edition of the Report focuses on national and international policies that promote knowledge as a catalytic input to the development of productive capacities in the Least Developed Countries. The Report discusses mechanisms and policies to enhance technology transfers to these countries; the role of intellectual property rights and related incentive systems; and the ways in which foreign aid can be used to promote technological learning and innovation capabilities in the Least Developed Countries.
