This paper employs multivariate regression to forecast the calorie intake of Bangladeshi farm households in the hunger season based on the household income, production, and demographic composition in the current (post harvest) season. Nutritional vulnerability profiles are derived from the estimation of ex ante mean and variance of future consumption. The results show the income increase induced by introducing transgenic rice will reduce each individual household's probability of suffering a future consumption shortfall and its vulnerability. The overall vulnerability profile of farm households improves in Bangladesh. |

Marker-assisted breeding could have a major impact in relieving productivity constraints that cannot as easily or rapidly be relieved by conventional breeding alone. This paper estimates the benefits of using marker-assisted breeding, as compared to conventional breeding alone, in developing cassava varieties resistant to cassava mosaic disease, green mite, whitefly and post-harvest physiological deterioration in Nigeria, Ghana and Uganda. Marker-assisted breeding is estimated to save at least four years in the breeding cycle for varieties resistant to the pests and to result in incremental net benefits over 25 years in the range of $34 to $800 million depending on the country, the particular constraint and various assumptions. Benefits may reach as high... |

The focus of this analysis is to measure, by use of production functions, the contribution to total output of not only the quantity of traditional inputs (land, labor, fertilizer, etc.), but also the quality of certain inputs, particularly irrigation; technology; environmental factors (soil types, rainfall, etc.); and infrastructure (transportation, markets, etc.). |

Growers and community leaders have expressed interest in establishing a horticultural shipping-point market in Southwest Virginia. This paper reports on a study that assessed whether horticultural production would be profitable in the region and, if so, the physical and organizational requirements for a successful shipping-point market. It appears that tomatoes, peppers, and pumpkins can be produced and marketed profitably to large-volume wholesale buyers if growers meet the exacting requirements of the retailers. A cooperative association is the organizational structure with the greatest chance of success. At the conclusion of this study, a shipping-point market in the recommended form was established in Southwest Virginia. |

Results are presented from estimating the value of research, clinical practice, and education for a college of veterinary medicine. Short-run impacts are estimated using input-output analysis. Long-run benefits are estimated using a combination of economic surplus analysis, travel cost analysis and demand estimation, animal-owner willingness-to-pay based on a survey of practicing veterinarians, and earnings differentials |

Estimates of marginal products and rates of return to cash grains, dairy, poultry, and other livestock research in the United States were made by Bredahl and Peterson using 1969 Census of Agriculture data. Their results showed national returns to crop and livestock research to be in the 36 to 46% range. These estimates of returns, several times higher than market rates, have proven useful to agricultural researchers and administrators in supporting budget requests. Bredahl and Peterson provided marginal products by commodity groups by states which have been used by economists in particular states to calculate rates of return to research on commodity groups in those states (Mitchell, Coffey, Babb, and Pratt). More recently, Davis has provided evidence that... |

Agricultural development is essential for improved well-being in rural Ecuador. As much as 40% of the population relies on agriculture as its primary source of income and agricultural exports account for a significant proportion of foreign exchange revenue. In the highlands, potatoes are a major staple, and more than 90,000 producers grow them on about 60,000 hectares of land. Potato production is associated with heavy use of chemical inputs--pesticides and fertilizers--to manage pests and optimize profits. Concerns have emerged about the sustainability of Ecuador's potato crop as rising input costs have created a cost squeeze and public health officials are increasingly concerned about health consequences of pesticide over use. Producers need... |
