| In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil. Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output. If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&D spending, the... |

| As the number and variety of interconnected sources of agricultural innovations have continued to grow and evolve, so too have the demands for meaningful evidence of both the total payoff and the specific impacts of individual research providers. Important policy and practical funding decisions require a clear understanding of the shares of the overall benefits from investments in R&D attributable to domestic versus foreign and public versus private agencies, or even to individual agencies, as well as the total benefits accruing from innovation. This report provides a detailed economic assessment of the magnitude and sources of the economic benefits to Brazil since the early 1980s from varietal improvements in upland rice, edible beans, and... |

| Since 2002, the United States Agency for International Development (USAID) has funded programs to promote maize, dairy, and horticulture enterprises among smallholder farmers in Kenya under the Strategic Objective 7 of Increased Rural Household Incomes. On behalf of USAID, Tegemeo Institute has conducted household surveys to help track key indicators that monitor progress in the implementation of these programs. The first survey was conducted in 2004. Subsequent surveys were conducted every two years (i.e., 2006, 2008, and 2010). The sample comprises households participating and those not participating in the programs. The programs monitored include the Kenya Maize Development Program (KMDP), the Kenya Horticulture Development Project (KHDP), and the Kenya... |
