Implications of Transgenic Rice for Farm Households' Nutritional Vulnerability: Projections for Bangladesh
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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?
Provedor de dados: 31
Autores: 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?
Provedor de dados: 31
Autores: 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...

AGRICULTURAL COOPERATION AND PRODUCE MARKETING IN SOUTHWEST VIRGINIA
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

Autores: 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.

Policy for Plenty: measuring the benefits of policy-oriented social science research
Provedor de dados: 31
Autores: Norton,   George W.; Alwang,   Jeffrey Roger.
This paper suggests practical methods for assessing policy research programs, both ex post and ex ante. Measuring the benefits of policy research is difficult: the path of causation between research and policy change is nearly always uncertain; multiple factors influence any particular policy change; policies are diverse in nature as are their intended and actual effects; and some effects of policy research are not priced in the market. Many of the benefits of changes in policy stem from the reduced cost of welfare-improving institutional change. Economic surplus analysis can be used to assess such changes. In some cases, Bayesian decision theory may be helpful in evaluating policy research, although it is usually difficult to obtain estimates of the...

THE EFFECTS OF SECTORAL AND ECONOMY-WIDE POLICIES ON TOBACCO PRODUCTION IN THE DOMINICAN REPUBLIC
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

Autores: 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,...

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.

THE ECONOMIC IMPACT OF GENETICALLY MODIFIED ORGANISMS IN SMALL DEVELOPING COUNTRIES
Provedor de dados: 31
Autores: 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.

Micro simulated general equilibrium approach was used to analyze the economic significance of the current export promotion policy of Ethiopia. Simulation results, in general, indicated little achievements of economic growth and poverty reduction under selective export promotion. In this policy approach, only rural households were able to acquire higher income and lower poverty incidence. These achievements however were transmitted to small and big urban households when export promotion was assumed to be implemented across the board of all agricultural activities. Significant economic and inter-industrial growths were attained when the coffee industry was given equal policy treatments like other export agriculture

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...
