Measuring Returns to Research Expenditures for Corn, Wheat and Soybeans AgEcon
Sundquist, W. Burt; Cheng, Cheng-Ge; Norton, George W..
A wealth of information exists on ex post returns to research investments for agriculture in the aggregate and for several agricultural commodity groups of commercial importance in the United States. Many of the investments made in agricultural research and, consequently, many of the allocative decisions on research funding, are, however, commodity-specific. Probably the main reason for the limited empirical literature on returns to commodity-specific research is that of the limited production input data available for individual commodities. Data from the U.S. Census of Agriculture, for example, do not permit commodity disaggregation beyond that employed by Bredahl and Peterson. Their analysis which utilizes commodity groups including cash crops, dairy,...

POTENTIAL BENEFITS OF TRANSGENIC RICE IN ASIA: A GENERAL EQUILIBRIUM APPROACH AgEcon
Hareau, Guy Gaston; Norton, George W.; Mills, Bradford F.; Peterson, Everett B..
A general equilibrium model is developed to analyze the welfare effects of transgenic technologies for both the irrigated and non-irrigated rice ecosystems in Asia. Drought resistance, a technology of particular importance to unfavorable environments, is worth as much as Bt rice, a technology of primary importance to favorable environments.

THE ECONOMIC IMPACT OF GENETICALLY MODIFIED ORGANISMS IN SMALL DEVELOPING COUNTRIES AgEcon
Hareau, Guy Gaston; Mills, Bradford F.; Norton, George W.; Bosch, Darrell J..
The expected benefits from herbicide resistant transgenic rice in Uruguay are estimated with stochastic simulation techniques. Economic surplus methods that account for private profits are used to measure the magnitude and distribution of the benefits between producers and a multinational firm. Further, the adoption rate of transgenic rice is endogenous in the model and depends on the expected profitability of the technology. The results show that the potential benefits from the technology are relatively small because of the small production base. Multinational firms are, therefore, unlikely to develop locally adapted transgenic rice varieties without strategic partnerships with local institutions.

ESTIMATING RETURNS TO AGRICULTURAL RESEARCH, EXTENSION, AND TEACHING AT THE STATE LEVEL AgEcon
Norton, George W.; Coffey, Joseph D.; Frye, E. Berrier.
The majority of decisions concerning investment and allocation of public funds for agricultural research, extension, and teaching (RET) are made at the state-level, while most of the quantitative RET evaluations are made on a national basis. This paper illustrates an approach for conducting a disaggregated state-level evaluation of agricultural research, extension, and teaching. Ridge regression is employed to handle multicollinearity problems.

FARM-HOUSEHOLD ANALYSIS OF POLICIES AFFECTING PEANUT PRODUCTION IN SENEGAL AgEcon
Akobundu, Eberechukwu; Norton, George W.; Gaye, Matar; Bertelsen, Michael.
A farm-level survey of 150 households was conducted in the peanut basin of Senegal, and a profit function system estimated, for the purpose of analyzing the effects of policies affecting the peanut sector. Producer price of peanuts has relatively little effect on production, but producer price of millet influences peanut seed demand.

AGRICULTURAL COOPERATION AND PRODUCE MARKETING IN SOUTHWEST VIRGINIA AgEcon
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.

Potential Effects of Transgenic Rice on Farm Households' Nutritional Status in Bangladesh AgEcon
Liang, Yan; Reaves, Dixie Watts; Norton, George W..
The spread of agricultural biotechnology in developing countries has grown rapidly in recent years. Several transgenic products are under development with potential to address a variety of adverse production conditions. These products have raised hope that yield and quality improvements in rice will accelerate and help in the battle against under-nutrition, especially in areas of prevalent under-nutrition in Asia. A farm household model is developed and estimated to project ex ante effects of introducing transgenic rice on farm households¡¯ nutritional status in Bangladesh. Assuming the yield effects of transgenic rice are similar to that of previous high yield varieties, the model estimates the profit effect of introducing transgenic rice. The profit...

THE EFFECTS OF SECTORAL AND ECONOMY-WIDE POLICIES ON TOBACCO PRODUCTION IN THE DOMINICAN REPUBLIC AgEcon
Pena, Pedro Pablo; Norton, George W..
This study analyses the effects of specific agricultural and exchange rate policies on tobacco production in the Dominican Republic. Direct protection resulting from output and input subsidies and taxes was positive on average from 1966 to 1988, but total protection was negative when exchange rate policies are considered. Tobacco policies were quite volatile and resulted in increasing production in the 1970s but decreasing production in the 1980s. Overall, tobacco production was 4.8 percent less than it would have been had there been no policy interventions. Several reasons are provided for the policies.

Effectiveness of Integrated Pest Management Dissemination Techniques: A Case Study of Potato Farmers in Carchi, Ecuador AgEcon
Mauceri, Maria; Alwang, Jeffrey Roger; Norton, George W.; Barrera, Victor.
Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields. Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability. Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed. We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission. Field days and pamphlets have strong impacts on adoption, especially considering their low costs. FFS are effective, but expensive. Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high...

Is the Share of Agricultural Maintenance Research Rising? AgEcon
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? AgEcon
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...

The Cost of Biotechnology Regulation in the Philippines AgEcon
Bayer, Jessica C.; Norton, George W.; Falck-Zepeda, Jose Benjamin.
This paper identifies direct costs and opportunity costs of bio-safety regulation for four transgenic products in the Philippines: Bt eggplant, Bt rice, ringspot-virus resistant papaya, and virus resistant tomatoes. It finds that direct regulatory costs while significant, are generally smaller than the research costs for technology development. However, both research and regulatory costs are overshadowed by even a relatively brief delay in product release, which may occur due to unexpected regulatory delays.

Economic Impact Analysis of Marker-Assisted Breeding in Rice AgEcon
Alpuerto, Vida; Norton, George W.; Alwang, Jeffrey Roger.
The benefits of developing and releasing salinity-tolerant and phosphorous-deficiency-tolerant rice in Bangladesh, India, Indonesia and the Philippines were estimated for marker-assisted breeding as compared to conventional breeding using economic surplus analysis. Marker-assisted breeding is estimated to save at least 2 to 3 years in the breeding cycle and result in incremental benefits over 25 years in the range of $300 to $800 million depending on the country, stress, and time lags. Salinity and phosphorous deficient soils are difficult problems to solve through conventional breeding because of “genetic load” or undesirable traits that accompany desirable ones during backcrossing. MAB, enabled by advances in genomics and molecular mapping is more...
