In the most comprehensive evaluation ever conducted of the World Bank's work in trade, the Bank's Independent Evaluation Group (IEG) has found that the Bank neither fully understood the implications of its "narrow focus on trade liberalisation", nor did enough to strengthen trade capacity on the ground. While the evaluation shies away from challenging head-on the economics of the Bank's promotion of unilateral trade liberalisation, it points out a number of serious flaws in the institution's understanding of how to maximise the benefits to be had for developing countries.
