| 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. |

| This paper focuses on the private and social rates of return to R&D capital in the three vertically linked sectors, primary agriculture, food processing, and farm machinery and equipment. Evidence supporting a divergence between these rates is found for primary agriculture and food processing. Using a cost function approach, the private rates of return to R&D capital ranged from an average of 10.2% per annum for food processing to 22.3% for farm machinery and equipment. In the case of agriculture, the direct return to public R&D averaged 37.3% per annum. The social rates of return to R&D capital in agriculture and food processing are significantly larger than the private rates due to the existence of spillovers. While the divergence between... |

| The NERICA (New Rice for Africa) rice varieties, developed by the Africa Rice Center during the 1990s, are providing hopes for raising the productivity of upland rice farmers in Africa because of their reported high yield potential and adaptability to the African conditions. The varieties are new and not widely disseminated in farming communities and there is lot of interest in the donor community in knowing their potential for widespread adoption across sub-Saharan Africa (SSA). However, when a technology is new and the target population is not universally exposed it, the observed sample adoption rate and classical models of adoption widely used in adoption studies does not inform reliably on its potential adoption and constraint to it in the full... |

| Agricultural research in marginal dry areas can contribute to reducing poverty through the development of technological, institutional and policy options for poor farmers by addressing diversified opportunities and development pathways. This paper analyzes the diversity of rural livelihood strategies in the Khanasser Valley in northwest Syria, an area representative of marginal drylands. We experimentally define an operational classification of household typologies based on their different livelihood strategies, capabilities, and opportunities by applying a Sustainable Livelihoods framework. Livelihoods diversity has implications on where and how research must be targeted to have impact on poverty. Households less endowed in land and natural resources and... |

| There is in Europe a trend for privatisation and commercialisation of technical extension services for agriculture. At the same time, extension is supposed to support the contribution of multifunctional agriculture (MFA) to rural development. This article proposes an analytic framework to test whether performances of commercial extension enable to enhance the effectiveness of intangible investments in MFA context. Empirical investigations were realised about technical extension for cereal production in Ain (France) and Zeeland (Netherlands). It appears that [A] private extension providers hardly invest in R&D relevant to MFA context; [B] some farmers who contribute to MFA may lack technical knowledge when provided by commercial extension. |

| This paper examines the linkages among agricultural total factor productivity, farm size, and farm household participation in the off-farm labor market for the Southeastern states for the period 1960-1996. We find evidence of a simultaneous relationship between productivity and measures of farm structure. The results support the expected relationships between the endogenous variables, namely that productivity and farm size are positively related, farm size and off-farm work participation are negatively related, and off-farm work and productivity are negatively related. We find positive and significant impacts of government policies (investments in public research, extension, and highways) on productivity growth. |

| Based on their theoretical predictions, Kliauga, de Gorter, and Just (2008) and de Gorter, Drabik, and Just (2010) argue that the United States and the European Union establish the world ethanol and biodiesel prices, respectively. We test these theories using cointegration analysis and the Vector Error Correction (VEC) model. Weekly price series are analyzed for the major global biofuel producers (European Union, United States, and Brazil) for the period 2002 – 2010. Polices in the United States and Brazil appear to play an equal role in determining ethanol prices in other countries, thus only partially confirming the theoretical predictions. For biodiesel, our results demonstrate that the EU mandate impacts the world biodiesel price and thus they confirm... |

| We study the demand by organic farmers for technical advice using a quantile regression for the demand of organic farmers for consultations with private information providers. There is substantial heterogeneity in the impact of critical explanatory variables on consultations of organic farmer. Larger farm size has a positive effect on contacts, but the effect is absent for the highest number of consultations. Internet use has a positive marginal effect on visits to private information providers across each quantile, suggesting that expanded efforts to deliver programs through web-based resources are a useful investment for information providers. |

| 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. |

| In the United States, biomass is the largest source of renewable energy accounting for over 3 percent of the energy consumed domestically and is currently the only source for liquid, renewable, transportation fuels. Continued development of biomass as a renewable energy source is being driven in large part by the Energy Independence and Security Act of 2007, which mandates that by 2022 at least 36 billion gallons of fuel ethanol be produced, with at least 16 billion gallons being derived from cellulose, hemi-cellulose, or lignin. However, the market for cellulosic biofuels is still under development. As such, little is known about producer response to feedstock prices paid for dedicated energy crops. While there have been some studies done on factors that... |
