The project consisted of eighteen country studies that employed a common analytical framework and entailed close collaboration between the investigators and the project's three codirectors. This volume deals with six countries in Africa and the Mediterranean region: the Arab Republic of Egypt, Ghana, Morocco, Portugal, Turkey, and Zambia. The remaining countries are also orga- nized by region in two other volumes, which examine Latin America (Volume 1) and Asia (Volume 2). Volumes 4 and 5 present a synthesis and comparative analysis of the findings from each country study. The purpose of the project was threefold: to provide systematic esti- mates of the degree of price discrimination against agriculture within individual countries and to explain how it changed over time; to deter- mine how this intervention affected such key variables as foreign ex- change earnings, agricultural output, and income distribution; and to gain further insight into the political economy of agricultural pricing policy through a study of the motivations of policymakers, the eco- nomic and political factors determining the degree of agricultural inter- vention, and the attempts to reform unsuccessful policies. Until recently, analysts were primarily concerned with the direct effect that agricultural pricing policies might have on agricultural prod- uct and input prices. According to international trade theory and gen- eral equilibrium analysis, however, a policy that protects one particular sector of the economy (in this case, industry) is essentially imposing a tax on other sectors of the economy (in this case, agriculture). The tax is likely to raise the real exchange rate, which will then lower the real return to exportables and unprotected import-competing sectors, which account for most of agriculture. Indeed, a country's general economic policies may have far greater indirect effect on agricultural incentives than its agriculture-specific or direct pricing policies do. That is why this project proceeded on the premise that it is impossi- ix x Preface ble to judge the impact of a developing country's policies without an understanding of the relative importance of direct and indirect inter- vention. This approach also provides an effective means of evaluating the political economy of agricultural pricing policies across a number of countries, as explained in the final volumes of this series. The system- atic examination of the impact of these policies on output, consump- tion, government budgets, foreign trade, intersectoral transfers, and income distribution in itself contributes a great deal to our understand- ing of the workings of these policies in developing countries. Economic growth is such a complex process that it is extremely diffi- cult to interpret accurately. Because it consists of many phenomena changing simultaneously, the effects of particular policies are hard to isolate, especially if the policies have been in place for a long time. To deal with this problem, we asked the researchers to test three hypoth- eses in each country study: (a) agricultural pricing policies elicit eco- nomic responses (in the market, for example) and political responses (among pressure groups, bureaucratic organizations, and voter blocs) that affect the evolution of those policies; (b) the results of the policies may differ significantly from-and in some cases be opposite to-what was intended when they were adopted; and (c) the costs of price intervention are usually underestimated and tend to rise over time. Several criteria were used to select the countries for the project. A foremost concern was to represent a reasonable range of country expe- rience. Therefore, some countries in the group are exporters of food, others are exporters of agricultural (but nonfood) commodities, and still others are importers of food. An effort was also made to achieve some balance between low-income and middle-income countries, as well as among geographic regions. The task would have been impossi- ble without able researchers willing to participate in the project and to prepare the country reports (published as individual volumes in the World Bank Comparative Studies series). The countries included
