| Rates of obesity among adults and children in the U.S. are soaring, with potentially huge private and social costs. Increasing attention is being paid to agricultural policies as both the culprits through their perceived roles in reducing the relative prices of energy-dense foods, and as the potential saviors through their perceived ability to do the opposite. However, the effects of agricultural policies on human nutrition and obesity are not well understood. This paper considers (1) trends in agricultural commodity prices, and the contributions of commodity policies and agricultural R&D policies to those trends, (2) the links between changes in commodity prices and changes in food prices; and (3) the implications of price-induced changes in food... |

| Personal digital assistants (PDA) and handheld global positioning systems (GPS) have become increasingly important in cotton production but little is known about their use. This research analyzed the adoption of PDA/handheld GPS devices in cotton production. A younger farmer who used a computer in farm management and had a positive perception of Extension had a greater likelihood of adopting the devices. In addition, farmers who used complementary remote sensing, plant mapping, and grid soil sampling information were more likely to use PDA/handheld GPS devices. Finally, the COTMAN in-field decision support program from Extension also positively impacted adoption. |

| Hog producers in Indiana and Nebraska were surveyed about sources of risk, effectiveness of risk management strategies, and prior participation in and desire for additional risk management education. Ownership of hogs by the producer, size of the operation, and age did have significant effects on ratings of both sources of risk and effectiveness of risk management strategies. Probit analysis found age, prior attendance, knowledge and prior use of the tool, level of integration, and concern about price and performance risk have significant effects on interest in further education about production contracts, futures and options, packer marketing contracts, and financial management. |

| The possibility of increased production of genetically modified (GM) crops in agriculture accentuates the need to examine the feasibility of GM and non-GM technologies coexisting on a common physical landscape. Using the theory of clubs, this paper examines the possibility of coexistence for GM and organic wheat technologies through the formation of an organic club with an endogenously determined buffer zone. Given the available data on prices, yields, and rotations, it is shown that a club can be created in which GM and organic agricultural production technologies can economically co-exist in the same physical landscape. Specifically, co-existence results in an increase in economic welfare over a situation where only GM technology is used but is not... |

| In this paper we consider factors that affect both crop prices and yields in order to examine supply responses of major crops in the Southeast. Due to the variable nature of crop production in the Southeast, previous studies that ignore price and yield risk may fail to capture one of the salient features of the region’s agriculture. Our results indicate supply elasticity values for corn, cotton, and soybeans of approximately 0.670, 0.506, and 0.195, respectively. Compared with the results of studies in other regions, corn and cotton acres respond more to price changes and soybean acres respond less to price changes. |
