Implications of Transgenic Rice for Farm Households' Nutritional Vulnerability: Projections for Bangladesh 31
Liang, Yan; Reaves, Dixie Watts; Norton, George W..
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.

Economic impact analysis of marker-assisted breeding for resistance to pests and post harvest deterioration in cassava 31
Rudi, Nderim; Norton, George W.; Alwang, Jeffrey Roger; Asumugha, Godwin N..
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...

Is the Share of Agricultural Maintenance Research Rising? 31
Sparger, John Adam; Heisey, Paul W.; Alwang, Jeffrey Roger; Norton, George W..
This study measures the amount of agricultural research engaged in maintenance research for commodities and non-commodities. The percentage of commodity based maintenance research has risen from roughly 35% in 1986 to 41% in 2008. The percentage of non-commodity based agricultural research is roughly 29%. Additionally, an empirical model is developed to explain maintenance research expenditures. The influences of agricultural research funding, climatic conditions, pest and pathogen control, and agricultural production on maintenance research expenditures are tested in the long and short run. Each category has a statistically significant impact on maintenance research expenditures.

Pesticide Use and IPM Adoption: Does IPM Reduce Pesticide Use in the United States? 31
Maupin, Jason; Norton, George W..
In 2001, the United States General Accounting Office issued a report entitled “Management Improvements Needed to Further Promote Integrated Pest Management.” This report documents that overall agricultural pesticide usage increased from 1992 to 2000 while the use of the most toxic levels of pesticides have decreased. The USDA suggests that these changes in pesticide use could have been caused by integrated pest management (IPM) adoption. However, the GAO maintains that there is not enough evidence to support this claim. This paper contributes to this debate by estimating the relationship between pesticide use and IPM practices adopted for number of commodities across the nation from 1996 to 2005. The paper exploits an aggregated data set that...

REGIONAL DIFFERENCES IN AGRICULTURAL PRODUCTIVITY IN SELECTED AREAS OF INDIA 31
Easter, K. William; Abel, Martin E.; Norton, George W..
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.).

AGRICULTURAL COOPERATION AND PRODUCE MARKETING IN SOUTHWEST VIRGINIA 31
Trupo, Paul; Colavito, Luke A.; Reaves, Dixie Watts; Coale, Charles W., Jr.; Norton, George W..
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.

ECONOMIC ANALYSIS OF ENVIRONMENTAL BENEFITS OF INTEGRATED PEST MANAGEMENT 31
Mullen, Jeffrey D.; Norton, George W.; Reaves, Dixie Watts.
Public support for integrated pest management (IPM) is derived in part from concerns over food safety and the environment, yet few studies have assessed the economic value of health and environmental benefits of IPM. An approach is suggested for such an assessment and applied to the Virginia peanut IPM program. Effects of IPM on environmental risks posed by pesticides are assessed and society's willingness to pay to reduce those risks is estimated. The annual environmental benefits of the peanut IPM program are estimated at $844,000. The estimates of pesticide risks and willingness to pay can be applied elsewhere in economic assessments of IPM.

The Productivity and Allocation of Research: U.S. Agricultural Experiment Stations, Revisited 31
Norton, George W..
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...

Adoption of Integrated Pest Management Technologies: A Case Study of Potato Farmers in Carchi, Ecuador 31
Barrera, Victor; Norton, George W.; Alwang, Jeffrey Roger; Mauceri, Maria.
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...
