Book Description
Much empirical research has shown that individuals’ decisions to adopt a new technology are the result of learning–both through personal experimentation through observing the experimentation of others. Yet even casual observation would suggest significant heterogeneity of learning processes, manifesting itself in widely varying patterns of adoption over space and time. This paper explores this heterogeneity in the context of early adoption of hybrid rice in rural India. Using specially designed experiments conducted as part of a primary survey in the field, we identify which of four broad learning heuristics most accurately reflects individuals’ information processing strategies. Linking these learning heuristics with observed use of rice hybrids, we demonstrate that pure Bayesian learning is well suited for the tinkering and marginal adjustments that are required to learn about a technology like hybrid rice, but it is also more cognitively taxing than other learning styles requiring a longer memory and more complex updating processes. Consequently, only about 25 percent of the farmers in our sample can be characterized as pure Bayesian learners. Present-biased learning and relying on first impressions will likely hinder adoption of a technology like hybrid rice, even after controlling for access to credit and a rudimentary proxy for intelligence.

Book Description
The U.S. Department of Agriculture (USDA) requested that the Board on Agriculture and Natural Resources of the National Research Council (NRC) convene a panel of experts to examine whether publicly funded agricultural research has influenced the structure of U.S. agriculture and, if so, how. The Committee to Review the Role of Publicly Funded Agricultural Research on the Structure of U.S. Agriculture was asked to assess the role of public-sector agricultural research on changes in the size and numbers of farms, with particular emphasis on the evolution of very-large-scale operations.

Book Description
Despite years of development interventions, agricultural productivity in Africa south of the Sahara still trails far behind all other continents, leaving many rural populations in dire poverty. This suggests that our understanding of the impacts of agricultural development projects is still imperfect; perfecting it is likely to be a crucial step in achieving development. Projects that raise agricultural productivity, in addition to directly affecting farmers, can have an impact on local prices, wages, and rents, especially in rural areas of Africa, which tend to be less-than-perfectly integrated with outside markets. Price changes, in turn, transmit project impacts to others within the local economy. This paper presents the findings of a local economywide impact evaluation of Feed the Future irrigation projects in the Morogoro region of Tanzania, using a local economy-wide impact evaluation (LEWIE) simulation model. The findings indicate that these irrigation projects can generate important indirect impacts within the region. The structure of local markets, as well as labor and land availability, shapes project spillovers in ways that point to future directions for development assistance in the region.

Book Description
The purpose of the research summarized in this paper is to provide policy-relevant knowledge on the governance of rural services in Guatemala and thus to contribute to improving the provision of services that are essential for agricultural and rural development. Almost 10 years ago, the Guatemalan government decided to strengthen decentralization and community participation to improve the quality of public services, as well as access to these services for the poor, especially in rural areas. Based on quantitative and qualitative primary data, we examine how services are actually provided today and how community preferences and participation affect service provision in rural Guatemala. Our main finding is that the provision of formally decentralized services by local governments is incomplete. As a result, many rural communities continue to lack access to services, and some of them engage in supplying these services themselves. However, communities do not consider themselves to be more effective at service provision and would therefore prefer to be served by the government. Moreover, we find that community participation in the planning and evaluation of services has a positive impact on the responsiveness of the local governments service provision. However, the effectiveness of community participation varies greatly among the examined cases, with several participatory governance bodies not functioning properly due to low education levels, poverty, and weak civil-society organization.

Book Description
This study has been undertaken to understand and evaluate the potential negative consequences of export taxes which are implemented by many countries today and which are not disciplined by any international agreement. This paper uses a new detailed global dataset on export taxes at the HS6 (Harmonized System 6 level) level and the MIRAGE (Modeling International Relationships in Applied General Equilibrium) global computable general equilibrium model to assess the impact of export taxes on the world economy. We find that limitations on export taxes would have worldwide effects: the average export tax on global merchandise trade was 0.48 percent in 2007, with the bulk of these taxes imposed on energy products. The removal of these taxes would increase global welfare by 0.23 percent, which is a larger figure than the expected gains from the World Trade Organizations Doha Development Round. Both developed and emerging economies, such as China and India, would gain from such policies, even if they currently impose export taxes. Medium and small food-importing countries without market power (such as the least-developed countries) would also benefit from the elimination of export restrictions, especially during food crisis situations. Both the energy sector and the export taxes implemented by Commonwealth of Independent States countries appear to play a critical role in the overall economic impact of such a policy change. However, the fact that some countries, such as Argentina, would experience income losses due to such a policy change is a major challenge to overall positive reform in this area.

Book Description
Despite the importance of Southeast Asia (SEA) region in the world for economy and agriculture, and despite reported evidence of the modernization of various aspects of the agricultural sector, the information has not been compiled in ways that provides more representative insights of the regions, as well as chronological, dynamic perspectives across different aspects of the overall agricultural developments. This report partly fills this knowledge gap by summarizing the key characteristics in SEA region of the agricultural development, as well as changes in related outcomes, such as nutrition, natural resource endowments, and the labor movement into non-farm economies. In doing so, the report gathers secondary cross-country data on key aspects of the agricultural modernization and diversification. Overall, the SEA region has seen a relatively fast movement of labor out of the agricultural sector into non-farm sectors including trade, restaurants and hotel industries in the last few decades, leading to higher labor productivity growth than land productivity growth. Despite the important roles of trade, the agricultural production within the region and in each country continues to account for important sources of food and nutrition. The modern production technologies and inputs have spread constantly within the region, but with considerable time lags across countries. The growth of vegetable oils and aquaculture production have been considerable, and contrast with South Asia (SA)where similar patterns have been observed for vegetables and milk production. The public sector has played important roles in agricultural research and development (R&D)on genetic improvements, and infrastructure development, while keeping the nominal assistance to the sector through market interventions to a relatively modest level, which has been accompanied by the significant growth of the private-sector participation in the provisions of inputs, services and agricultural finance. The agricultural modernization in SEA region has, however, been also associated with some negative outcomes, including continued degradation of natural resources like water and forest areas in which SEA has been relatively rich historically, and gradual increases in certain types of malnutrition including overweight and diabetes.

Book Description
Americans praise medical technology for saving lives and improving health. Yet, new technology is often cited as a key factor in skyrocketing medical costs. This volume, second in the Medical Innovation at the Crossroads series, examines how economic incentives for innovation are changing and what that means for the future of health care. Up-to-date with a wide variety of examples and case studies, this book explores how payment, patent, and regulatory policiesâ€"as well as the involvement of numerous government agenciesâ€"affect the introduction and use of new pharmaceuticals, medical devices, and surgical procedures. The volume also includes detailed comparisons of policies and patterns of technological innovation in Western Europe and Japan. This fact-filled and practical book will be of interest to economists, policymakers, health administrators, health care practitioners, and the concerned public.

Book Description
Asian countries have witnessed a sharp increase in real wage as a result of rapid economic growth and structural transformation in recent years. Using a country level panel data from 1980 to 2010, this paper examines the effects of real wage increase on Asian agriculture that traditionally used family labor intensively on small farms. The empirical evidence supports our hypothesis that an increase in real wages, along with absorptions of labor into nonagricultural sectors, has been inducing the substitution of labor by machines in agriculture. However, this process is less successful in the countries that are constrained by their small operational land sizes, resulting in lowered land productivity. We also demonstrated that dynamic changes in yield are an important determinant of food self-sufficiency ratio. The above findings imply that in the near future, Asian agriculture can face a challenge in maintaining domestic food production. Given the large size of consumer demands in the region and its increasing trend, the future path of Asian agriculture could be a significant constraint on the global food supplydemand balance.
