I. THE CASE OF THE WORLD MARKET FOR COTTON
Comparative advantage is not fixed in time but changes as countries develop their economies. Agriculture is an area where many countries experience a declining comparative advantage over time. Some agricultural crops tend to be very labor intensive, and the cost of labor rises as an economy develops. Technology may solve some of the problems of rising wages by reducing the need for labor, but other crops resist an efficient technological solution. In an ideal world, workers in industries that lose their comparative advantage would easily and quickly move to an
industry where new opportunities appear. Comparative advantage in agriculture is not the only concern countries have when thinking about their agricultural sector. Issues of food safety, food independence, and support for rural culture and society are all concerns to one degree or another, more in some countries than others. One objective of World Trade Organization (WTO) is to create an economic environment in which low-cost agricultural producers have access to other countries' markets. The goal is to create greater efficiency in the world economy by locating production where the opportunity costs are lowest, while at the same time creating
opportunities for developing countries. Cotton is not a food crop, but it highlights some of the fundamental difficulties involved in persuading countries to drop trade barriers, as well as the fundamental reasons why it is desirable to see barriers fall. According to the International Cotton Advisory Committee, the highest cost producers in the world include Greece, Spain, and the
United States, all of which are countries classified as high-income by the World Bank. Lowest-cost producers are in sub-Saharan western Africa (e.g., Burkina Faso, Mali, Benin) and central Asia (e.g., Uzbekistan and Tajikistan). Cotton is not a major item in world trade, accounting for only about 0.12 percent of total merchandise trade in 2003. Nevertheless, it is important. As many as one hundred million households depend on income earned growing
cotton, and several of the low-cost producers depend on their cotton export earnings to buy essential imports such as grain. Table 3.5 compares cotton production, its share of trade, and income per person in a few of the low-cost and high-cost producers. As shown, low-cost countries produce less but depend more on cotton exports, as their very low levels of income put them close to the edge of survival and they have fewer goods to export. High-cost producers depend much less on their cotton exports and have much higher incomes. High-cost producers like the United States and Greece depend on a variety of government interventions to keep their cotton producers in business. In Greece, direct and indirect payments, along with tariffs on imports of cotton, are administered through the European Unions Common Agricultural Program. In the United States, the Department of Agriculture administers a number of farm support programs, including payments to farmers, subsidized loans, revenue guarantees, subsidized insurance, marketing and promotion assistance, and others, while the Department
Commerce administers a set of tariffs on foreign cotton entering the U.S. market.
Rich countries that try to keep their high-cost producers in business have consequences beyond the immediate effect of keeping production going where it is less efficient.
A. In economic terms, what should be happening for producers of cotton in Western Africa or Central Asia if they could successfully export their cotton crop? First, provide economic reasons why they should be exporters, and describe what gains from trade such exporters should expect.
B. Which countries should have declining comparative advantage? Why, however, are they still exporting?
C. Explain in economic terms exactly who is being disadvantaged in this situation, and how they are being disadvantaged.
D. What recommendations would contribute to greater economic efficiency in the world cotton market?TABLE 3.5 Sample of Low-Cost and High-Cost Cotton Producers in World Market
