| Information generated by precision farming technologies is of particular importance to producers. Precision farming technologies implies the ability to improve the management of production factors using site-specific information. This study examines factors influencing cotton farmers’ perceptions about the importance of crop consultants, farm input dealerships, Extension, other farmers, trade shows, the Internet and printed news/media for making precision farming decisions using a rank ordered logit model (ROLM). Results suggest that age, land tenure, income, percentage of income from farming, and location may affect farmers’ perceptions about the importance of different information sources when making decisions about precision farming technologies.... |

| Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the number of specific types of precision agriculture technologies adopted by cotton farmers. Particular attention is given to the influence of spatial yield variability on the number of precision farming technologies adopted, using a Count data estimation procedure and farm-level data. Results indicate that farmers with more within-field yield variability adopted a larger number of precision agriculture technologies. Younger and better educated producers and the number of precision agriculture technologies were significantly correlated. Finally, farmers using computers for... |

| We used survey data collected from cotton farmers in 12 southern U.S. states to identify factors influencing cotton farmers’ decisions to adopt precision farming. Using a seemingly unrelated ordered probit model, we found that younger, educated and computer literate farmers chose precision farming for profit reason. Farmers who perceived precision farming to be profitable adopt it to be at the forefront of agricultural technology. We also found that farmers who were concerned with environment emphasize precision farming adoption as a reason to improve environmental quality. Our results also indicate that farmers in coastal states such as Alabama, Mississippi, and North Carolina chose environmental benefits as a reason for precision farming technology... |

| Communities in most states are under pressure to reduce the amount of solid waste going into landfills. Many are making efforts to encourage their citizens to practice backyard composting. A logit regression analysis was conducted to identify factors associated with backyard composting of yard and food wastes in a case study area. Sample data were obtained through a September 1997 telephone survey of 865 households residing in single-family dwellings in Knox County, Tennessee. Findings indicate that a number of variables reflecting complementary behavior, attitudes, knowledge, and peer influence were significantly related to composting behavior. Policy implications of these findings are outlined. |

| This research uses a sequence of hedonic housing price regressions to estimate open space amenity values. The iterative approach empirically identifies the range of distance over which open space affects housing values. After controlling for numerous other factors in the spatial hedonic model, simple functional relationships were established between the implicit prices of developed open space, forest-land open space, and agriculture-wetland open space and the buffer radius of the area surrounding a given location. In the case of Nashville-Davidson County, Tennessee, households place a positive value on additional developed open space and forest-land open space up to distances of 2.2 miles and 1.5 miles, respectively, and a negative value for additional... |

| Econometric models designed to show how national policies affect state agricultural sectors often use national prices as proxies for state prices. Consequently, they ignore the influence of freight rates on state production. An application to the Hawaii beef industry demonstrates that both freight rates and national beef prices have important impacts on Hawaii beef prices and production. By using state prices rather than national prices, error from changes in freight rates might be reduced, and the model's capacity for policy analysis might be broadened. |

| A model describing the choice of technology is developed from theoretical considerations. It is shown that the model can be approximated using a logit function. Estimates of short-run elasticities are easily obtained. The model is then applied to the decision to place feeder cattle in confined feeding situations or on range. With one possible exception, the results are consistent with theoretical expectations and with previous studies. |

| The main objective of this research is to propose a data-driven approach to estimate the amenity values of restoring urban forest landscapes at potential target sites. The approach allows establishing the overall price-driving time relationship between the amenity values attributable to both deforested and forested areas and their proximities to housing locations within a given community. Establishing the overall price-driving time relationship is important because the hedonic price model cannot be used to estimate the amenity values of yet to be restored urban forest landscapes that do not exist at the time of housing sales transactions. We estimated the sum of the differences between amenity values of deforested and forested areas on housing prices... |

| The following hypothesis was tested: Willingness to bear a negative water impairment externality differs between those who do and those who do not receive economic benefit from the impairment source, e.g., a paper mill. The hypothesis was tested using a hedonic analysis of ambient water quality in two discrete housing markets in the Pigeon River Watershed, which have been polluted by the operation of a paper mill. The results suggest that North Carolina residents of the subwatersheds with impaired river, who experience economic benefits from the paper mill in addition to harmful effects, do perceive the pollution as a negative externality, whereas they may have a willingness to bear a similar type of negative externality associated with impaired streams.... |
