Analyze alternative national and international strategies and policies for meeting foof needs of the developing world on a sustainable basis, with particular emphasis on low-income countries and on the poorer groups in those countries.
Proceedings of a conference by the Standing Panel on Impact Assessment (SPIA) of the Interim Science Council, Consultative Group on International Agricultural Research (CGIAR) and the Economics Program, the International Maize and Wheat Improvement Center (CIMMYT), 4-7 February 2002, San José, Costa Rica.
Serving as a companion to Growing Up Global, this book from the National Research Council explores how the transition to adulthood is changing in developing countries in light of globalization and what the implications of these changes might be for those responsible for designing youth policies and programs. Presenting a detailed series of studies, this volume both complements its precursor and makes for a useful contribution in its own right. It should be of significant interest to scholars, leaders of civil society, and those charged with designing youth policies and programs.
The growth in agricultural R&D investments around the world has slowed considerably in the past 20-30 years, even though most experts agree that there is substantial underinvestment in agricultural R&D. Introducing a simple economic model of the ex ante selection of R&D projects allows us to make a more insightful interpretation of the available ex post rate-of-return evidence. Two sets of factors can be identified that determine the level of investment in agricultural R&D: (1) the ex ante choice set of R&D projects for a given domain and time and (2) the extent to which the assumptions of full information and selection rationality apply
This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both positive and normative implications for growth. In positive terms, the prospect of a high level of research in the future can deter research today by threatening the fruits of that research with rapid obsolescence. In normative terms, obsolescence creates a negative externality from innovations, and hence a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which the log of GNP follows a random walk with drift. The size of the drift is the average growth rate of the economy and it is endogenous to the model ; in particular it depends on the size and likelihood of innovations resulting from research and also on the degree of market power available to an innovator.
This book documents frontier knowledge on the drivers of agriculture productivity to derive pragmatic policy advice for governments and development partners on reducing poverty and boosting shared prosperity. The analysis describes global trends and long-term sources of total factor productivity growth, along with broad trends in partial factor productivity for land and labor, revisiting the question of scale economies in farming. Technology is central to growth in agricultural productivity, yet across many parts of the developing world, readily available technology is never taken up. We investigate demand-side constraints of the technology equation to analyze factors that might influence producers, particularly poor producers, to adopt modern technology. Agriculture and food systems are rapidly transforming, characterized by shifting food preferences, the rise and growing sophistication of value chains, the increasing globalization of agriculture, and the expanding role of the public and private sectors in bringing about efficient and more rapid productivity growth. In light of this transformation, the analysis focuses on the supply side of the technology equation, exploring how the enabling environment and regulations related to trade and intellectual property rights stimulate Research and Development to raise productivity. The book also discusses emerging developments in modern value chains that contribute to rising productivity. This book is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers.
