Adoption of Variability Detection and Variable Rate Application Technologies by Cotton Farmers in Southern United States AgEcon
Nair, Shyam; Wang, Chenggang; Segarra, Eduardo; Belasco, Eric J.; Velandia, Margarita M.; Reeves, Jeanne M..
A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen. The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs. The farmers adopting both soil and plant based VDTs are more likely to adopt VRT. The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted. In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they...

Can Education Be a Barrier to Technology Adoption? AgEcon
Uematsu, Hiroki; Mishra, Ashok K..
The objective of this study is to test the widely‐held belief that the effect of education has a positive impact on technology adoption. Using 2006 Agricultural Resource Management Survey "ARMS" data, we estimate a simultaneous equations model to integrate farmers’ labor allocation decision with adoption of GM crops and precision farming. We confirm that the marginal effect of education on technology adoption is significantly larger for large farms for both GM crops and precision farming and it is unexpectedly negative for GM crops at all levels of farm size. These results suggest that formal education can be a barrier to technology adoption, especially for small scale farmers who have higher tendency to work off‐farm.

Does “Convenience Agriculture” Affect Off‐farm Labor Allocation Decisions? AgEcon
Uematsu, Hiroki; Mishra, Ashok K.; Chintawar, Sachin.
The objective of this study is to examine the effect of adoption intensity of GM crops on off‐farm labor supply by farm households. Using ARMS data in 2004, 2005 and 2006, we estimate a two stage simultaneous Tobit model and find that adoption intensity of GM crops has a negative impact on off‐farm labor supply by operators and a positive impact on off‐farm labor supply by spouse. This may be due to the comparative advantage of operators and spouses. Our results find that GM crops adoption has different but significant implications on off‐farm labor supply by operators and spouses and underscores the importance of understanding farm households’ decisions to explain behaviors of farm businesses in the United States.

Innovation Behaviour At Farm Level – Selection And Identification AgEcon
Sauer, Johannes; Zilberman, David.
Using a squential logit model and a mixed-effects logistic regression approach this empirical study investigates factors for the adoption of automatic milking technology (AMS) at the farm level accounting for problems of sequential sample selection and behaviour identification. The results suggest the importance of the farmer’s risk perception, significant effects of peer-group behaviour, and a positive impact of previous innovation experiences.

Irrigation Technology Adoption Under Factor Price Uncertainty: Groundwater- Irrigated Production in Nebraska, 1960 -- 2005 AgEcon
Savage, Jeff; Brozovic, Nicholas.
The development of groundwater-irrigated production technologies, fed by water from the Ogallala Aquifer, facilitated the development of agriculture in the High Plains region of the United States that began during the 1960s. The current rate of pumping for irrigation in the region is causing the aquifer to be depleted in many areas, which is cause for concern from a socioeconomic and environmental standpoint. The goal of this paper is to assess the factors that affect the decision to adopt groundwater-irrigated production by farmers, in the presence of risk differentiated by heterogeneous farmland quality and groundwater depth. A binary choice model of adoption is estimated for Nebraska, from 1960 – 2005. The results suggest that farmers consider climate...

Motivation for Technology Adoption and Its Impact on Abandonment: A Case Study of U.S. Cotton Farmers AgEcon
Uematsu, Hiroki; Mishra, Ashok K.; Roberts, Roland K.; Lambert, Dayton M.; English, Burton C..
We estimate a bivariate probit model with sample selection to identify factors affecting adoption and abandonment of precision farming technologies for cotton farmers, using the 2009 Southern Cotton Precision Farming Survey conducted in 12 Southern states in the United States. Farmers for whom being at the forefront of agricultural technology is not an important reason for adoption are more likely to abandon precision farming technologies. This study identified various factors associated with adoption and retention of precision farming technologies. Findings from this study offer significant information to policy‐makers for a better formulation of agri‐environmental programs that encourage farmers to adopt environmentally benign farming practices...

Read the Label! Energy Star Appliance Awareness and Uptake Among U.S. Consumers AgEcon
Murray, Anthony G.; Mills, Bradford F..
The Energy Star label program to promote the diffusion of energy efficient home appliances is arguably the most significant government effort to reduce U.S. residential energy consumption. Program effectiveness requires that consumers are aware of the labeling scheme and also change their purchase decisions based on label information. This paper examines the factors associated with consumer awareness of the Energy Star label of recently purchased ‘white’ major appliances and the factors associated with the choice of Energy Star labeled appliances. The paper finds that household characteristics have a much stronger association with consumers awareness of labels than with the choice of Energy Star appliances. Renting the home, Hispanic ethnicity, being poor...

Social Learning and Parameter Uncertainty in Irreversible Investment----Evidence from Greenhouse Adoption in Northern China AgEcon
Wang, Honglin; Reardon, Thomas.
This paper introduces social learning into irreversible investment theory through parameter uncertainty, and shows that social learning could reduce parameter uncertainty to facilitate irreversible investment technology adoption. The theoretic model is tested by using household level data from energy saving greenhouse adoption in northern China, and empirical evidences are consistent with the theory: social learning has significantly positive impacts on greenhouse adoption, while market volatility discourages the adoption.

Taking a New Look at Empirical Models of Adoption: Average Treatment Effect Estimation of Adoption Rates and their Determinants AgEcon
Diagne, Aliou.
This paper shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. It is proved that instead the sample adoption rate is a consistent estimate of the population joint exposure and adoption rate, which does not inform about adoption per se. Likewise, it is shown that a model of adoption with observed adoption outcome as dependent variable and where exposure to the technology is not observed and controlled for cannot yield consistent estimates of the determinants of adoption. Such model can at best provide consistent estimates of the effects of the included explanatory variables on joint exposure and adoption. Even for that to be possible, the model must be explicitly specified as...

The Effect of Risk, Ambiguity and Coordination on Farmers’ Adaptation to Climate Change: A Framed Field Experiment AgEcon
Alpizar, Francisco; Carlsson, Fredrik; Naranjo, Maria.
The risk of losses of income and productive means due to adverse weather associated to climate change can significantly differ between farmers sharing a productive landscape. It is important to learn more about how farmers react to different levels of risk, under measurable and unmeasurable uncertainty. Moreover, the costs associated to investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore these issues using a framed field experiment that captures realistically the main characteristics of production, and the likely weather related losses of premium coffee farmers in Tarrazu, Costa Rica. Given that the region recently was severely hit by an extreme, albeit very infrequent, climatic event, we expected to...

Tomato Farmers and Modern Markets in Nicaragua: A Duration Analysis AgEcon
Hernandez, Ricardo; Reardon, Thomas.
This paper explores whether farm land and non-land assets determine the participation of tomato growers in modern markets in Nicaragua, and how farmers’ duration as supermarket suppliers affects the farm technology they use. The methodology is based on a survival analysis approach. We use data from a stratified random sample of tomato farmers in Nicaragua over a 10-year period. Our results show that participation in supermarket supply chains as supermarket supplier is not determined by farm size, contrary to a common hypothesis, and thus small farmers can be supermarket suppliers. However, non-land assets are important determinants of being in the modern channel: these assets include irrigation, nonfarm assets (linked to nonfarm employment) and education....
