| Consolidations and spin-offs in the agricultural biotechnology industry and the growing links of multinational corporations with the food and feed industry have been the subject of considerable discussion among academics, policy makers, consumers, and farmers. Most of the research by academic and overnment institutions has focused on the reasons for consolidation. Little theoretical or empirical research has examined the impact of this consolidation. We adapt an endogenous growth model of industry structure and R&D to agricultural biotechnology and empirically estimate the model. These empirical estimates, the main focus of the paper, indicate that industry consolidation influences the amount and direction of research, which then feeds back to... |

| Meeting growing global demand for food, fiber, and biofuel requires robust investment in agricultural research and development (R&D) from both public and private sectors. This study examines global R&D spending by private industry in seven agricultural input sectors, food manufacturing, and biofuel and describes the changing structure of these industries. In 2007 (the latest year for which comprehensive estimates are available), the private sector spent $19.7 billion on food and agricultural research (56 percent in food manufacturing and 44 percent in agricultural input sectors) and accounted for about half of total public and private spending on food and agricultural R&D in high-income countries. In R&D related to biofuel, annual... |

| 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... |

| Over the years, proposals have recommended shifting the focus of public agricultural research from applied to basic research, and giving higher priority to peer-reviewed, competitively funded grants. The public agricultural research system in the United States is a Federal-State partnership, with most research conducted at State institutions. In recent years, State funds have declined, USDA funds have remained fairly steady (with changes in the composition of funding), but funding from other Federal agencies and the private sector has increased. Efforts to increase competitively awarded funds for research have fluctuated over time, as have special grants (earmarks). Along with shifts in funding sources, the proportion of basic research being undertaken... |
