The prices of farm products are crucial determinants of the extent of poverty and inequality in the world. The vast majority of the world's poorest households depend to a considerable extent on farming for their incomes, while food represents a large component of the consumption of all poor households. For generations, food prices have been heavily distorted by government policies in high-income and developing countries. Many countries began to reform their agricultural price and trade policies in the 1980s, but government policy intervention is still considerable and still favors farmers in high-income countries at the expense of many farmers in developing countries. What would be the poverty and inequality consequences of the removal of the remaining distortions to agricultural incentives? This question is of great relevance to governments in evaluating ways to engage in multilateral and regional trade negotiations or to improve their own policies unilaterally.Agricultural Price Distortions, Inequality, and Poverty analyses the effects of agricultural and trade policies around the world on national and regional economic welfare, on income inequality among and within countries, and on the level and incidence of poverty in developing countries. The studies include economy-wide analyses of the inequality and poverty effects of own-country policies compared with rest-of-the-world policies for 10 individual developing countries in three continents. This book also includes three chapters that each use a separate global economic model to examine the effects of policies on aggregate poverty and the distribution of poverty across many identified developing countries. This study is motivated by two policy issues: first, the World Trade Organization's struggle to conclude the Doha Round of multilateral trade negotiations, in which agricultural policy reform is, again, one of the most contentious topics in the talks and, second, the struggle of the developing countries to achieve their Millennium Development Goals by 2015 - notably the alleviation of hunger and poverty - which depends crucially on policies that affect agricultural incentives.

to establish impact, attributing observed changes in welfare to the intervention, while identifying key factors of success. Impact evaluations are aimed at providing feedback to help improve the design of programs and policies. They also provide greater accountability and a tool for dynamic learning, allowing policymakers to improve ongoing programs and ultimately better allocate funds across programs. Such a causal analysis is essential for understanding the relative role of alternative interventions in reducing poverty. The papers in this section again adopt a variety of techniques. The rst two impact evaluation studies employ propensity score matching to establish, ex-post, a valid control group to assess the impact on child schooling outcomes among b- e ciaries of various interventions in Kenya and Ethiopia. The third chapter c- ries out an ex-ante evaluation of alternative cash transfer programs on child school attendance in Uruguay. The nal paper further carries out in-depth macro-modeling and micro-regression analysis to simulate the impacts of the food crisis and various policy responses, including food subsidies and cash transfers, on various dimensions of child poverty in Mali. Though using different approaches, the studies are gen- ally in agreement concerning the positive impact of the cash transfer program on child schooling and labor market outcomes. The studies from Kenya and Uruguay both nd that the schooling interventions are progressive.

Public spending on infrastructure plays an important role in promoting economic growth and poverty alleviation. In that context, the financing of infrastructure has been a critical element of most economic growth and poverty reduction strategies in developing countries, since the start of this millennium.
