Abstract: While barriers to trade in most goods and some services including capital flows have been reduced considerably over the past two decades, many remain. Such policies harm most the economies imposing them, but the worst of the merchandise barriers (in agriculture and textiles) are particularly harmful to the world's poorest people, as are barriers to worker migration across borders. This paper focuses on how costly those anti-poor trade policies are, and examines possible strategies to reduce remaining distortions. Two opportunities in particular are addressed: completing the Doha Development Agenda process at the World Trade Organization (WTO), and freeing up the international movement of workers. A review of the economic benefits and adjustment costs associated with these opportunities provides the foundation to undertake benefit/cost analysis required to rank this set of opportunities against those aimed at addressing the world's other key challenges as part of the Copenhagen Consensus project. The paper concludes with key caveats and suggests that taking up these opportunities could generate huge social benefit/cost ratios that are considerably higher than the direct economic ones quantified in this study, even without factoring in their contribution to alleviating several of the other challenges identified by that project, including malnutrition, disease, poor education and air pollution.

"This is one of 10 studies for the Copenhagen Consensus Project that sought to evaluate the most feasible opportunities to improve welfare globally and alleviate poverty in developing countries. Anderson argues that phasing out distortionary government subsidies and barriers to international trade will yield an extraordinarily high benefit-cost ratio. A survey is provided of recent estimates using global economywide simulation models of the benefits of doing that by way of the current Doha round of multilateral trade negotiations. Even if adjustment costs are several times as large as suggested by available estimates, the benefit-cost ratio from seizing this opportunity exceeds 20. That is much higher than the rewards from regional or bilateral trade agreements or from providing preferential access for least-developed countries' exports to high-income countries. Such reform would simultaneously contribute to alleviating several of the other key challenges reflected in the United Nation's Millennium Development Goals"--Abstract.

The Role of Trade in Ending Poverty looks at the complex relationships between economic growth, poverty reduction and trade, and examines the challenges that poor people face in benefiting from trade opportunities. Written jointly by the World Bank Group and the WTO, the publication examines how trade could make a greater contribution to ending poverty by increasing efforts to lower trade costs, improve the enabling environment, implement trade policy in conjunction with other areas of policy, better manage risks faced by the poor, and improve data used for policy-making.
