| Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains... |

| The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of... |

| In “The Role of Agriculture in Economic Development,” written nearly a quarter of a century ago, Bruce Johnston and I discussed the principal means by which agriculture could assist in transforming a traditional low-income economy in a modern high-income one. In the intervening years the literature and much of the practice of development has been dominated by either emphasis on industrialization, independent of agricultural development, or on agriculture as a provider of basic human needs, independent of commercialization and industrialization. Perhaps the time is ripe to pick up the old threads of a dynamic interaction between agriculture and industry. Those threads lead to a very specific strategy for development of agriculture itself in which... |

| This research report is part of IFPRI's continuous efforts to understand the relationship between technological change in agriculture and overall economic growth that expands employment and income opportunities for the poor in developing countries. The research is a collaborative effort with the Centre for the Study of Regional Development at Jawaharlal Nehru University in New Delhi. The study documents and analyzes the structural changes that have occurred in the Punjab economy since the green revolution of the mid-1960s. With two input-output tables—one for 1969/70 and the other for 1979/80—the authors have traced the sources of structural changes and examined the changes in the intersectoral linkages and the quantum of indirect and induced income and... |

| The wide spread increase in rural purchasing power under the Green Revolution in Asia during the 1970s was key to increased rural employment and industrialization. Studies suggested that an extra dollar of agricultural income was typically associated with an additional $0.80 of nonagricultural income from local enterprises stimulated by the spending of farm house holds. Studies in Africa, where the Green Revolution was harder to discern, tended to be much more pessimistic. This report revisits these issues using especially detailed panel data sets on rural consumption and incomes, collected by IFPRI and collaborating national institutions for a variety of purposes during the mid to late 1980s in Burkina Faso, Niger, Senegal, Zambia, and Zimbabwe.

| In 1982 Dominga Cavallo and Yair Mundlak received an award for quality of research discovery from the American Agriculture Economics Association for IFPRI Research Report 36, Agriculture and Economic Growth in an Open Economy: The Case of Argentina. The research was sponsored jointly by IFPRI and the Instituto de Estudios Economicos Sobre la Realidad Argentina y Latinoamericana (IEERAL) of the Fundacion Mediteranea, and it in turn built on earlier prize-winning research by Mundlak, presented in Research Report 6, Intersectoral Factor Mobility and Agricultural Growth. The model developed for the study makes it possible to explore the effects of policies directed at agriculture as well as general macro and trade policies, taking into account interaction... |

| This research report highlights the findings from a set of studies undertaken by the International Food Policy Research Institute, along with several national and international research institutions, to assess the economic impact of improved cultivars and management practices on smallholder farmers in the Lake Victoria Region of Uganda and Tanzania— an area where the cooking banana is both economically and culturally important. Genetic transformation is a promising alternative for improving the resistance of banana plants to the pests and diseases that cause serious economic losses, because bananas, unlike rice, wheat, and maize, are difficult to improve through conventional breeding techniques. The team of researchers posed three broad questions: What is... |

| How potential entrants to an open-access fishery form their expectations determines the fishery’s adjustment path to a steady state but not the steady state values themselves. It is well known that, in the standard model with myopic expectations (those based on current values), boats enter the fishery only when the fish stock is greater than its steady state stock. We show that, with rational expectations (perfect foresight), however, boats may enter when the fish stock is much lower than its steady state value if the boat fleet is sufficiently small. This paper contrasts myopic and rational expectations within a general dynamic model of an open-access fishery. |

| As the number and variety of interconnected sources of agricultural innovations have continued to grow and evolve, so too have the demands for meaningful evidence of both the total payoff and the specific impacts of individual research providers. Important policy and practical funding decisions require a clear understanding of the shares of the overall benefits from investments in R&D attributable to domestic versus foreign and public versus private agencies, or even to individual agencies, as well as the total benefits accruing from innovation. This report provides a detailed economic assessment of the magnitude and sources of the economic benefits to Brazil since the early 1980s from varietal improvements in upland rice, edible beans, and... |
