| Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA’s coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework’s linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information’s value depends most heavily on farmers’ perceptions of the forecast’s accuracy. The study finds that the framework’s information is valuable... |

| This paper investigates the determinants of foreign direct investment (FDI) and its relationship to trade in the U.S. food processing industry. A representative multinational corporation maximizes profits by choosing between production in the home country, which is exported, and production in a foreign country. This introduces the possibility that foreign affiliate sales can be a substitute and/or complement for exports. The empirical framework consists of a system of four equations with foreign affiliate sales, exports, affiliate employment, and FDI as endogenous variables. The results confirm a small substitution between foreign affiliate sales and exports. The empirical evidence supports the hypothesis that FDI is also protection-jumping. |

| Error correction models impose few prior restrictions on dynamic model specification and allow the data to determine model structure. Despite this obvious advantage, few applications have adopted the error correction model to explain trade flows. An error correction model of cotton import demand is estimated for France, Japan, and Hong Kong. A variety of tests are applied to determine the dynamic structure of the model. We find the most general models are those that best fit the data for cotton import demand. Long-run elasticities from these general models are significantly different than elasticities derived from a comparable static model. |

| For U.S. agriculture to continue along a sustainable path of economic development, further production increases must be generated by technologies that are both profitable and more environmentally benign. In this context, we assess the role of these green or sustainable technologies in steering agriculture along a more sustainable path. However, the lack of markets for the environmental attributes associated with green technologies can limit their development. In addition, simply making a technology available does not mean it will be adopted. Experience with green technologies such as conservation tillage, integrated pest management, enhanced nutrient management, and precision agriculture demonstrates that even when technologies are profitable, barriers to... |

| Over the past three decades, the number of farming operations has remained relatively steady, but production has shifted to larger farms. Changes in production and marketing practices have facilitated—and have been facilitated by—organizational and distributional changes in agricultural production. Resulting changes in agricultural productivity helped keep prices for agricultural goods relatively low and reduced the environmental footprint for each unit of agricultural output produced, but not without tradeoffs. |

| This study investigates the effects of market structure and research and development (R&D) on the innovation activities of firms. Fixed and random effects count data models are estimated with firm-level data for the U.S. food processing industry. Results show a positive association between patents and R&D, and patents and market structure, suggesting that firms which exhibit noncompetitive behavior are likely to develop new products and processes. Significant intra-industry spillovers of knowledge are identified using industry R&D. For this industry, deadweight losses from imperfect competition may be offset by greater product variety and quality of food products for consumers. |
