An Economic Evaluation of Adoption of the Conservation Compliance Program: A Stochastic Dominance Approach AgEcon
Govindasamy, Ramu; Cochran, Mark J..
Using stochastic dominance, this paper examines the adoption of the Conservation Compliance Program (CCP) in twelve Iowa soil types. Subsidies necessary to compensate producers for the increased risk of compliance strategies are estimated. Results indicate that to promote voluntary compliance with the CCP, the government should provide a subsidy of between $4.55 to $19.88 per acre, depending on the soil type.

FARM COMPUTER ADOPTION IN THE GREAT PLAINS AgEcon
Hoag, Dana L.; Ascough, James C.; Frasier, W. Marshall.
Computers change rapidly, yet the last survey on computer use in agriculture was in 1991. We surveyed Great Plains producers in 1995 and used logit analysis to characterize adopters and non-adopters. About 37% of these producers use computers which is consistent with the general population. We confirmed previous surveys emphasizing the importance of education, age/experience, and other farm characteristics on adoption. However, we also found that education and experience may no longer be a significant influence. Future research and education could focus on when and where computers are most needed, and therefore when adoption is most appropriate.

EXPLAINING THE ADOPTION AND DISADOPTION OF SUSTAINABLE AGRICULTURE: THE CASE OF COVER CROPS IN NORTHERN HONDURAS AgEcon
Neill, Sean P.; Lee, David R..
Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent. This paper attempts to explain the recent decline in the use of cover crops using in maize farming in the Department of Atlantida, Honduras. In the early 1970's, farmers in the region began rotating maize with the velvetbean (mucuna ssp.), a system learned from Guatemalan immigrants. Tohe mucuna-maize system decreased the labor required for maize farming even as it increased yields, prevented erosion, and conferred a variety of other agronomic benefits. By 1992, estimates show that the system had diffused among more than 60% of farmers in the Department....

A GROUP INCENTIVE PROGRAM FOR FARMER ADOPTION OF BEST MANAGEMENT PRACTICES: AN APPLICATION TO THE NITRATE POLLUTION PROBLEM IN CENTRAL ILLINOIS AgEcon
Ipe, Viju C.; DeVuyst, Eric A..
The paper demonstrates a group incentive program to encourage farmer adoption of best management practices. It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. This may bring about a win-win situation for sponsor, the farmer participating in the program, and the society as a whole. The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments. The program could be implemented as an educational effort to...

SEQUENTIAL ADOPTION OF SITE-SPECIFIC TECHNOLOGIES AND ITS IMPLICATIONS FOR NITROGEN PRODUCTIVITY: A DOUBLE SELECTIVITY MODEL AgEcon
Khanna, Madhu.
This paper analyzes the sequential decision to adopt two site-specific technologies, soil testing and variable rate technology (VRT), and their impact on nitrogen productivity in four Midwestern states. The results indicate that while farm location was a key variable influencing the adoption of soil testing, human capital and innovativeness of farmers had a significant impact on the adoption of VRT. A double selectivity model applied to correct for sample selection bias shows that gains in nitrogen productivity due to the two adoption decisions are largest for farms with below average soil quality and statistically insignificant for farms with above average soil quality. These findings have implications for the targeting of public policies designed to...

DEFORESTATION AND AGROFORESTRY ADOPTION IN TROPICAL FORESTS: CAN WE GENERALIZE? SOME RESULTS FROM CAMPECHE, MEXICO AND RONDONIA, BRAZIL AgEcon
Casey, James F.; Caviglia-Harris, Jill L..
The adoption of sustainable agriculture and other sustainable forestry methods that can help to reduce tropical deforestation have received a great deal of attention in the literature (Adesina and Zinnah 1993, Akinola and Young 1985, Feder and Slade 1984, Holden 1993, Kebede et al. 1990). Although results from different studies can be compared in an absolute sense, there are very few individual studies that compare results and determine, through empirical analysis, whether policy can be universally applied. This paper uses farm-level data to determine whether some universal conclusions can be drawn about the adoption of agroforestry by peasant farmers in developing countries by comparing the land use choices of farmers in Rondônia, Brazil and Campeche,...

FACTORS AFFECTING ADOPTION OF IMPROVED MAIZE SEEDS AND USE OF INORGANIC FERTILIZER FOR MAIZE PRODUCTION IN THE INTERMEDIATE AND LOWLAND ZONES OF TANZANIA AgEcon
Kaliba, Aloyce R.; Verkuijl, Hugo; Mwangi, Wilfred.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm trials for varietal evaluation and demonstration purposes.

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown AgEcon
Kerr, Suzi; Newell, Richard G..
The theory of environmental regulation suggests that economic instruments, such as taxes and tradable permits, create more effective technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing technological responses to a dramatic decrease in allowed pollution levels - the petroleum industry's phasedown of lead in gasoline. Using a panel of refineries from 1971 to 1995, we provide some of the first direct evidence that alternative policies affect the pattern of adoption in expected ways. Importantly, we find that the tradable permit system used during the lead phasedown provided incentives for more efficient technology adoption decisions. Where environmentally appropriate, this suggests...

ECONOMIC ISSUES IN AGRICULTURAL BIOTECHNOLOGY AgEcon
Shoemaker, Robbin A.; Harwood, Joy L.; Day-Rubenstein, Kelly A.; Dunahay, Terry; Heisey, Paul W.; Hoffman, Linwood A.; Klotz-Ingram, Cassandra; Lin, William W.; Mitchell, Lorraine; McBride, William D.; Fernandez-Cornejo, Jorge.
Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural biotechnology encompasses many policy issues addressed in very different ways. We have identified several key areas — agricultural research policy, industry structure, production and marketing, consumer issues, and future world food demand — where agricultural biotechnology is dramatically affecting the public policy agenda. This report focuses on the economic aspects of these issues and addresses some current and timely issues as well as longer term issues.

THE BLENDING OF PARTICIPATORY RESEARCH AND QUANTITATIVE METHODS: WEALTH STATUS, GENDER AND THE ADOPTION OF IMPROVED FALLOWS IN ZAMBIA AgEcon
Franzel, Steven Charles; Phiri, Donald; Mafongoya, Paramu; Jere, Isaac; Katanga, Roza; Phiri, Stanslous.
Although there is increasing emphasis on targeting of improved technology towards poor and female farmers, few adoption studies assess the uptake of new practices by these groups in a comprehensive manner. In this study, community members used the wealth ranking method to identify the different wealth groups in their communities, to determine each household's wealth status, and to assess the association of wealth and different types of households with the planting of improved tree fallows, a practice for improving crop yields. There were no significant differences between the proportions of women and men planting improved fallows nor were there differences between single women and female heads of households who were married. There was some evidence of...

AN ECONOMIC ASSESSMENT OF THE WHOLE-FARM IMPACT OF PRECISION AGRICULTURE AgEcon
Olson, Kent D.; Elisabeth, Pascal.
The full impact of an investment in a management information system (MIS), such as precision agriculture (PA), comes from improved managerial decision making throughout the whole farm and not just from improvements in a specific part of the farm. This study was conducted to determine whether the adoption of PA had a positive impact on whole-farm profitability. To overcome problems of simultaneity and self-selection in the adoption decision of PA, this study used a two stage econometric model using data from farms in Southwest Minnesota. The PA adoption decision was evaluated in the first stage, and the impact of adopting PA was evaluated in the second stage. The whole farm rate of return to assets (ROA) was used to measure the impact of PA. For all 212...

ANALYSING THE LOW ADOPTION OF WATER CONSERVATION TECHNOLOGIES BY SMALLHOLDER FARMERS IN SOUTHERN AFRICA AgEcon
Perret, Sylvain R.; Stevens, Joe B..
Natural resource degradation and water scarcity are a global concern, which typically threatens the sustainability of smallholder farmers' livelihoods in semi-arid developing areas. As part of research efforts, a number of water-conservation technologies (WCT) have been developed, yet with low adoption rates in smallholder farming environments. This paper discusses the concepts of adoption and innovation, comparing the perspectives of research operators to the ones of smallholder farmers. Discrepancies are highlighted and ultimately explain low uptake of technologies by farmer. Then it addresses socio-economic factors affecting such adoption. It is argued that WCT show specific traits: (1) diversity and applicability to different time and spatial...

SOCIO-ECONOMIC IMPACT OF BIOTECHNOLOGY APPLICATIONS: SOME LESSONS FROM THE PILOT TISSUE-CULTURE (TC) BANANA PRODUCTION PROMOTION PROJECT IN KENYA, 1997-2002 AgEcon
Mbogoh, Stephen G.; Wambugu, Florence M.; Wakhusama, Sam.
This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive contribution to the socio-economic status of resource poor farmers in a developing country, such as Kenya. Adoption of tc technology in banana production in Kenya is considered a good example of biotechnological applications in agriculture. Hence the article hopes to make a contribution to recent debates at international levels as to whether biotechnology can make a difference in uplifting the living standards of people in the third world (Qaim, 1999; Graff, et al 2002;...
