| While the growing importance of off-farm earnings suggests large benefits accrue to farmers from efforts to expand off-farm income opportunities, survival still depends on greater efficiency. To comprehensively gauge the economic health of farm operator households we interpret off-farm income as an output along with corn, soybeans, livestock, and other crops. To accomplish this task we use two related methodologies. First, using 2000 data, we setup a multiactivity cost function to analyze labor allocation decisions within the farm operator household and also to estimate returns to scale and scope. Second, using 1996-2000 data, we follow an input distance function approach to estimate returns to scale, technical progress, cost economies, and technical... |

| This paper examines the impact of pesticide regulation on the number of new pesticide registrations and pesticide toxicity. Results suggest that regulation adversely affects new pesticide introductions but encourages the development of pesticides with fewer toxic side effects. The estimated regression model implies that a 10% increase in regulatory costs (about $1.5 million per pesticide) causes a 5% reduction in the number of pesticides with higher toxicity. |

| Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural biotechnology encompasses many policy issues addressed in very different ways. We have identified several key areas agricultural research policy, industry structure, production and marketing, consumer issues, and future world food demand where agricultural biotechnology is dramatically affecting the public policy agenda. This report focuses on the economic aspects of these issues and addresses some current and timely issues as well as longer term issues. |

| Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's. The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined. Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use. On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use. Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use. |

| This paper develops a methodology to calculate the impact of integrated pest management (IPM) on pesticide use, yields, and farm profits. The methodology is applied to the IPM adoption among fresh market tomato producers in eight states. The method is of general applicability. It accounts for self-selectivity and simultaneity, and the pesticide demand and yield equations are theoretically consistent with a profit function. The results support the notion that fresh market tomato growers who adopt IPM for insects and diseases apply significantly less insecticides and fungicides, respectively, than do those who do not adopt IPM; IPM adoption has an insignificant effect on yields and a small effect on profits. |

| Short- and long-run Hicksian and Marshallian elasticities are estimated, along with Morishima elasticities of substitution, using a restricted profit function and a series of decomposition equations. Convexity in prices and concavity in quasi-fixed factors of the restricted profit function are simultaneously imposed using Bayesian techniques. The empirical model is disaggregated in the input side, utilizes a Fuss-quadratic flexible functional form, incorporates the impact of agricultural policies, and introduces a new weather index. The methodology is applied to Illinois's agriculture, and implications for agriculture in the Corn Belt and the Northeast are briefly discussed. |

| Controversy over the use of genetically engineered (GE) crops may have induced some farmers to disadopt these seeds, making a traditional diffusion model inappropriate. In this study, we develop and estimate a dynamic diffusion model, examine the diffusion paths of GE corn, soybeans, and cotton, predict the adoption of those crops over the next two years, and explore the main determinants of the diffusion rate. Our estimates indicate that future growth of Bt crops will be slower or negative, depending mainly on the infestation levels of the target pests. Adoption of herbicide-tolerant soybeans and cotton will continue to increase, unless consumer sentiment in the United States changes radically. |

| The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe the outcomes of such decisions, such as onfarm and off-farm income. This report finds that a farm operator’s off-farm employment and off-farm income vary inversely with the size of the farm. Operators of smaller farm operations improve their economic performance by compensating for the scale disadvantages of their farm business with more off-farm involvement.... |

| The unprecedented growth in crop yields and agricultural total factor productivity over the past 70 years owes much to a series of biological innovations embodied in seeds, beginning with the development of hybrid crops in the United States in the early part of the 20th century, continuing with the adoption of high-yielding varieties during the Green Revolution of the 1960s and 1970s, and more recently, modern biotechnology. Throughout this period, the seed industry evolved, as small businesses gave way to larger enterprises that integrated plant breeding, production, conditioning, and marketing functions. The industry was further shaped by widespread mergers and acquisitions in the latter part of the century, rapid growth - in private research and... |

| Ten years after the first generation of genetically engineered (GE) varieties became commercially available, adoption of these varieties by U.S. farmers is widespread for major crops. Driven by farmers' expectations of higher yields, savings in management time, and lower pesticide costs, the adoption of corn, soybean, and cotton GE varieties has increased rapidly. Despite the benefits, however, environmental and consumer concerns may have limited acceptance of GE crops, particularly in Europe. This report focuses on GE crops and their adoption in the United States over the past 10 years. It examines the three major stakeholders of agricultural biotechnology and finds that (1) the pace of R&D activity by producers of GE seed (the seed firms and... |

| This paper examines how off-farm work affects the economic performance of crop and (selected) livestock farms. It estimates returns to scale and technical efficiency following an input distance function approach and compares the relative performance of dairy and corn farm operator households with and without off-farm work. We use farm-level data from the USDA's ARMS survey for 1996-2005. The impact of off-farm work on scale and technical efficiency is examined from two viewpoints: first, the effect of off-farm work on the scale and technical efficiency of the farm business in the production of traditional commodities (farm-level perspective); second, the impact of off-farm work on scale and technical efficiency at the household level, considering both... |
