A Binary Logit Analysis of Factors Impacting Adoption of Genetically Modified Cotton AgEcon
Banerjee, Swagata (Ban); Martin, Steven W..
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.

A Binary Logit Estimation of Factors Affecting Adoption of GPS Guidance Systems by Cotton Producers AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Roberts, Roland K.; Larkin, Sherry L.; Larson, James A.; Paxton, Kenneth W.; English, Burton C.; Marra, Michele C.; Reeves, Jeanne M..
Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

A Dynamic Adoption Model with Bayesian Learning: Application to the U.S. Soybean Market AgEcon
Ma, Xingliang; Shi, Guanming.
Agricultural technology adoption is often a sequential process. Farmers may adopt a new technology in part of their land first and then adjust in later years based on what they learn from the earlier partial adoption. This paper presents a dynamic adoption model with Bayesian learning, in which forward-looking farmers learn from their own experience and from their neighbors about the new technology. The model is compared to that of a myopic model, in which farmers only maximize their current benefits. We apply the analysis to a sample of U.S. soybean farmers from year 2000 to 2004 to examine their adoption pattern of a newly developed genetically modified (GM) seed technology. We show that the myopic model predicts lower adoption rates in early years than...

A Stochastic-Dynamic Model of Costly Reversible Technology Adoption AgEcon
Baerenklau, Kenneth A.; Knapp, Keith C..
We develop a stochastic-dynamic model of technology adoption that imposes fewer restrictions on behavior than do previous studies of similar decision problems. Like these previous studies, our model is forward-looking and can be used to demonstrate the additional "hurdle rate" that must be met before adoption will take place when the future state of the world is uncertain. Unlike these previous studies, our approach does not impose the untenable assumptions that investment in a new technology is irreversible or that technologies have unlimited useful lifetimes. Rather, we address the more reasonable situation of costly reversibility and limited lifetimes. Our solution method utilizes Bellman's equation and standard dynamic programming techniques....

Adapting the social-ecological system framework for urban stormwater management: the case of green infrastructure adoption Ecology and Society
Flynn, Carli D.; Department of Civil and Environmental Engineering, Syracuse University; cflynn@syr.edu; Davidson, Cliff I.; Department of Civil and Environmental Engineering, Syracuse University; Syracuse Center of Excellence in Environmental and Energy Systems; davidson@syr.edu.
Stormwater management has long been a critical societal and environmental challenge for communities. An increasing number of municipalities are turning to novel approaches such as green infrastructure to develop more sustainable stormwater management systems. However, there is a need to better understand the technological decision-making processes that lead to specific outcomes within urban stormwater governance systems. We used the social-ecological system (SES) framework to build a classification system for identifying significant variables that influence urban stormwater governance decisions related to green infrastructure adoption. To adapt the framework, we relied on findings from observations at national stormwater meetings in combination with a...

Adoção tecnológica e seus condicionantes: o caso da bananicultura no agropolo Cariri - CE AgEcon
Oliveira, Maria Aparecida Silva; Khan, Ahmad Saeed; Lima, Patricia Veronica Pinheiro Sales.
Utilization of technology in agriculture makes it productive and promissing, contributing to its development. Investiments done by Govern of Ceará in agriculture have concentrate mainly on irrigated agriculture, through the agropoles, prevailing fruit-growing, banana being one of the chief crops. Banana crop performs an important role for cearense agriculture, however, it is generally characterized by low productivity, low technological level and large losses in production. The objective of this study was to measure the technological level of the irrigated banana crop in Agropole Cariri and to verify which are the factors conditioning the technological adoption. The calculated index showed that the technological index adopted in banana crop is classified...

Adoption and Impact of Hybrid Wheat in India AgEcon
Matuschke, Ira; Qaim, Matin.
In the light of ongoing debates about the suitability of hybrid seeds for smallholder farmers, this paper analyzes the adoption and impact of hybrid wheat in India. Based on survey data we show that farmers can benefit significantly from the proprietary technology. Neither farm size nor the subsistence level influence the adoption decision, but access to information and credit matters. Moreover, willingness-to-pay analysis reveals that adoption levels would be higher if seed prices were reduced. Given decreasing public support to agricultural research, policies should be targeted at reducing institutional constraints, to ensure that resource-poor farmers are not bypassed by private sector innovations.

Adoption of Agricultural Production Practices: Lessons Learned from the U.S. Department of Agriculture Area Studies Project AgEcon
Caswell, Margriet; Fuglie, Keith O.; Ingram, Cassandra; Jans, Sharon; Kascak, Catherine.
The U.S. Department of Agriculture Area Studies Project was designed to characterize the extent of adoption of nutrient, pest, soil, and water management practices and to assess the factors that affect adoption for a wide range of management strategies across different natural resource regions. The project entailed the administration of a detailed field-level survey to farmers in 12 watersheds in the Nation to gather data on agricultural practices, input use, and natural resource characteristics associated with farming activities. The data were analyzed by the Economic Research Service using a consistent methodological approach with the full set of data to study the constraints associated with the adoption of micronutrients, N-testing, split nitrogen...

Adoption of an improved bean seed variety and consumption of beans in rural Madagascar: Evidence from a randomised control trial JARTS
Bosch, Christine; Zeller, Manfred; Deffner, Domenica.
This paper studies access to, and adoption of improved seed, as well as the diffusion of improved seed information in a remote area of central Madagascar. The analysis is based on panel data gathered from 2012 to 2014 from 390 households in three villages. In 2013, a randomised control trial was applied. Half of the 390 households were randomly assigned to receive improved lima bean seed (Phaseolus lunatus), which were specifically bred for dry regions. Of the seed-receiving households, 50 % were randomly assigned to receive information on how to store, plant, and cultivate the improved seed, as the variety was unfamiliar in the region. The control group and the two treatment groups are compared with respect to baseline characteristics, bean cultivation,...

ADOPTION OF BIOENGINEERED CROPS AgEcon
Fernandez-Cornejo, Jorge; McBride, William D..
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicidetolerant and insect-resistant varieties. In particular, the report examines: (1) the extent of adoption of bioengineered crops, their diffusion path, and expected adoption rates over the next few years; (2) factors affecting the adoption of bioengineered crops; and (3) farm-level impacts of the adoption of bioengineered crops. Data used in the analysis are mostly from USDA surveys.

Adoption of Conservation-Tillage Methods and Genetically Modified Cotton AgEcon
Roberts, Roland K.; English, Burton C.; Gao, Qi; Larson, James A..
Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related. Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis. Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

Adoption of Cover Crops and Its Effect on Nitrogen Use by Farmers AgEcon
Gabrielyan, Gnel; Chintawar, Sachin; Westra, John V..
With increasing environmental concerns, increasing population, changing tastes and preferences of consumers towards healthier foods, and with more food safety requirements, agronomic practices have changed gradually to provide not only food and fiber but also public goods and other beneficial services from agriculture. Cover cropping is one type of technology increasingly being adopted by producers of multifunctional agriculture. Cover crops provide a range of benefits, both private and public. In this paper we identify factors affecting farmers’ choice to adopt cover crops. We examine the impact on nitrogen use from adopting cover crops and the resultant decrease in input costs. Using a two-stage approach that incorporates endogeneity of adoption in...

Adoption of Site-Specific Information and Variable-Rate Technologies in Cotton Precision Farming AgEcon
Roberts, Roland K.; English, Burton C.; Larson, James A.; Cochran, Rebecca L.; Goodman, W. Robert; Larkin, Sherry L.; Marra, Michele C.; Martin, Steven W.; Shurley, W. Donald; Reeves, Jeanne M..
Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmer who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable-rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important, possibly because custom hiring shifts the burden of computer use to agribusiness firms.

Adoption of Soil Conservation Practices in Olive Groves: The Case of Spanish Mountainous Areas AgEcon
Calatrava-Leyva, Javier; Franco, Juan Agustin; Gonzalez-Roa, Maria del Carmen.
This paper presents some results from a survey carried out in 2004 among 223 olive tree farmers from mountainous areas in the Spanish Southern provinces of Granada and Jaen regarding the adoption of soil conservation and management practices. Olive tree groves in mountainous areas are subject to a high risk of soil erosion and have to incur in higher costs of soil conservation. This results in greater difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil...

Adoption of Technology, Management Practices, and Production Systems by U.S. Beef Cow-Calf Producers AgEcon
Pruitt, J. Ross; Gillespie, Jeffrey M.; Nehring, Richard F.; Qushim, Berdikul.
Using USDA’s Agricultural Resource Management Survey data, factors leading to the adoption of technology, management practices, and production systems by U.S. beef cow-calf producers are analyzed. Binary logit regression models are used to determine impacts of vertical integration; region of the U.S.; farm size, diversification, and tenure; and demographics on adoption decisions. Significant differences were found in adoption rates by region of the U.S., degree of vertical integration, and size of operation, suggesting the presence of economies of size and vertical economies of scope. Results also indicate high degrees of complementarity among technologies, management practices, and production systems.

Adoption of Transgenic Crops by Smallholder Farmers in Entre Rios, Argentina AgEcon
Paredes, Cecilia; Martin, Marshall A..
This is a study of the adoption of transgenic crops by 120 smallholder farmers interviewed in July 2005 in the communities of San Jose de Feliciano and La Paz in the Entre Rios Province of Argentina. Logistic regression results indicate that access to a planter is essential for smallholders to adopt Bt corn, while adopters of Roundup Ready™ soybeans have larger farms, access to credit, availability of all essential machinery, more years of schooling, and are primarily located in the La Paz community.

After the Bubble: The Survival and Ownership of Internet Marketplaces for Farmers and Agribusiness AgEcon
Wheatley, W. Parker; Buhr, Brian L..
This paper presents a theory of how industry structure and beliefs about Internet marketplace use have driven choice and ownership of marketplaces. The theory's predictions suggest that surviving Internet marketplaces will be those with strong historical linkages in an industry and those owned by or affiliated with major commodity buyers. Comparisons of these predictions with actual outcomes provide validation of the theory. Where predictions differ from results, observations are made as to the nature of the deviations.
