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 has 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 that not only fills that void for recent years but extends the estimates in a consistent and comparable way back in time's 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. This title provides an overview of the evolution of distortions to agricultural incentives caused by price and trade policies in the Arab Republic of Egypt plus 20 countries that account for about of 90 percent of Sub-Saharan Africa's population, farm households, 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. Nonetheless, numerous price distortions in this region remain, others have been added in recent years, and there has also been some backsliding, such as in Zimbabwe. 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.
