The new World Development Report examines how knowledge influences development. The report reinforces some well-known lessons, such as the value of the knowledge gained through trade and foreign investment, and highlights others that have sometimes been overlooked, such as how imperfect information leads to failures in all markets and the importance of institutions to facilitate the flow of information.
Knowledge about technology includes practical knowledge, such as basic knowledge about nutrition and birth control, and technical knowledge, such as knowledge about engineering and computer programming, that can be used to formulate solutions to problems such as transportation bottlenecks, water pollution, and inadequate housing. Differences in the level of knowledge about technology, known as knowledge gaps, are large and threaten to increase the gap in income between more advanced and less advanced countries.
Knowledge about attributes includes information about product quality, worker diligence, and creditworthiness-all of which are crucial to effectively functioning markets. Problems caused by incomplete understanding of attributes, known as information problems, tend to be more severe in developing countries, which often lack mechanisms, such as product standards, training certification, and credit reports, that can mitigate these problems. Information failures also tend to disproportionately affect the poor.

The green revolution illustrates the potential for increases in
information to improve living conditions and foster economic growth in
the developing world. The early phases of the green revolution largely
involved narrowing knowledge gaps; once the appropriate technology was
developed, problems of information failure were addressed.
The green revolution began in the 1950s, when new crops and farming techniques were introduced into much of the developing world. After the first modern seed varieties proved successful, many developing countries established national agricultural research organizations to develop second-generation varieties better suited to local conditions. To disseminate this information, governments sent extension agents out into rural areas to convince farmers to adopt the new seed varieties. Good agents quickly learned that listening was also an important part of their job. By listening to farmers and learning from them, agents gained a better understanding of farmers' needs and concerns-and sometimes stumbled on seed varieties and cultivation techniques that researchers had missed. This two-way flow of information furthered local adoption and adaptation of green revolution technology. Getting farmers to adopt the new technologies required more than merely providing them with the right know-how. Although large landholders and farmers with more education were often ready and able to try the new seeds, many poor farmers were unwilling to do so, fearing that the yields might not be as abundant as the extension agents claimed. Even after the experience of large neighboring farms showed that the seeds did indeed provide better yields, many poor farmers were unable to switch because they could not obtain credit with which to purchase seeds. This credit market failure reflected the fact that the cost to lenders of identifying creditworthy farmers among the poor was high relative to the size of the loans that were needed. Poor farmers' risk aversion and lack of access to credit during the green revolution meant that many of these farmers adopted the new crop strains only long after they were introduced. The costs of these delays were significant. If all poor farmers had been willing and able to adopt the new seeds right away, the productivity gains from the green revolution would have been much greater. According to one study, for a family farm with 3.7 hectares the average loss of potential income over five years from slow adoption and inefficient use of high-yielding varieties was nearly four times its annual farm income before the introduction of the new seeds. These figures suggest the critical importance of dealing with information problems in order to disseminate knowledge quickly and equitably. |
The rapid increase in knowledge in the high-income industrial
countries would seem to suggest that the knowledge gap between the
industrial and developing worlds is likely to continue to grow. But
poorer countries need not rediscover the treatment for malaria or
design their own computers; they can acquire and adapt much of the
knowledge already available in richer countries. In fact, countries
that adopt a technology late can often leapfrog intermediate
technologies, moving directly to the front ranks of technological
sophistication. The telephone networks in Djibouti, the Maldives,
Mauritius, and Qatar, for example, are fully digitized. In contrast,
many industrial countries still rely heavily on older analog
technology in place for decades, which is more expensive and lower in
quality.
To narrow the knowledge gap, developing countries must acquire, absorb, and communicate technical knowledge. Governments can increase the acquisition of knowledge by opening their countries to knowledge from abroad. They can increase the absorption of knowledge by educating their people. And they can disseminate technical knowledge by taking advantage of advances in telecommunications technology, which allow vast amounts of information to be sent cheaply across the world in seconds.

| Educators in Latin America and Africa have developed innovative, technology-based programs that reach thousands of students. The Virtual University of the Monterrey Institute of Technology in Mexico delivers university-level courses through live and prerecorded television broadcasts. Students and faculty communicate by computers and the Internet. The African Virtual University, headquartered in Nairobi, uses distance learning to increase university enrollments and improve the quality and relevance of instruction in business, science, and engineering throughout Africa. The university has installed 27 satellite receiver terminals throughout Africa and developed a digital library to compensate for the dearth of scientific journals in African universities. |
Information is the lifeblood of markets, but private agents do not
always provide enough of it. Because the market for knowledge often
fails, public intervention is needed.
Requiring publicly traded firms to meet standard accounting and disclosure requirements is another way in which governments can reduce information failures. Such standards allow potential investors to compare performance across firms and gauge the safety of financial institutions. This makes the financial system more efficient, which contributes to economic growth. According to one study, if Argentina had raised its accounting standards in the early 1990s to the average then prevailing in a group of high-income economies, its annual GDP growth would have increased by 0.6 percentage point.
The government can also enhance quality without taking direct action itself, by publicizing the availability of specialized private institutions that verify the quality of goods and services, for example, or establishing an institutional and legal environment that fosters the private setting of standards. Quality certification is especially important to exporters in developing countries that are eager to convince skeptical overseas buyers of the quality of their goods.
Because poor people know their own needs and circumstances, taking time to listen to them can greatly improve outcomes. In Colombia, for example, scientists allowed local farmers to choose among 20 new bean varieties. Thanks largely to the farmers' better knowledge of their terrain and their personal interest in increasing yields, their selections outperformed those chosen by the scientists by 60-90 percent. Such participation by beneficiaries has been shown to have a powerful impact on the outcomes of development projects: according to a study of 121 rural water supply projects in 49 countries, 7 out of 10 projects succeeded when the intended beneficiaries participated in project design, but only 1 in 10 succeeded when they did not.
Development institutions can also play an important role as knowledge intermediaries. No single country can amass and make accessible the vast pool of international knowledge about what works and what does not; international institutions have the capacity to gather and assess this information and make it available throughout the world.
International institutions can also use information technology to manage and disseminate the growing wealth of knowledge. Toward that end, the World Bank plans to make relevant parts of its knowledge base available to clients, partners, and stakeholders around the world by 2000.
