Book excerpt: The vast majority of the world's poorest households depend on farming for their livelihoods. During the 1960s and 1970s, most developing countries imposed pro-urban and anti-agricultural policies, while many high-income countries restricted agricultural imports and subsidized their farmers. Both sets of policies inhibited economic growth and poverty alleviation in developing countries. Although progress has been made over the past two decades to reduce those policy biases, many trade- and welfare-reducing price distortions remain between agriculture and other sectors and within the agricultural sector of both rich and poor countries. Comprehensive empirical studies of the disarray in world agricultural markets appeared approximately 20 years ago. Since then, the Organisation for Economic Co-operation and Development had provided estimates each year of market distortions in high-income countries, but there have been no comparable estimates for the world's developing countries. This volume is the third in a series (other volumes cover Africa, Europe's transition economices, and Latin America and the Caribbean) that not only fills that void for recent years but extends the estimates in a consistent and comparable way back in time and provides analytical narratives for scores of countries that shed light on the evolving nature and extent of policy interventions over the past half-century. 'Distortions to Agricultural Incentives in Asia' provides an overview of the evolution of distortions to agricultural incentives caused by price and trade policies in the 12 largest economies of East and South Asia. Together these countries constitute more than 95 percent of the region's population, agricultural output, and overall GDP. Sectoral, trade, and exchange rate policies in the region have changed greatly since the 1950s, and there have been substantial reforms since the 1980s, most notably in China and India. Nonetheless, numerous price distortions in this region remain and others have added in recent years. The new empirical indicators in these country studies provide a strong evidence-based foundation for assessing the successes and failures of the past and for evaluating policy options for the years ahead.
