Assessing U.S. Corn Production Technology

This study addresses several questions: (1) is a soybean yield limit being reached?, (2) what is the rate of return to soybean research, and is the research effect stable over time?, (3) are technology spill-overs between states important?, (4) do input and output price fluctuations affect...

Scientists were surveyed as part of as assessment of five emerging biotechnologies which are potentially applicable to commercial U.S. maize production by the year 2000. The largest gains expected by scientists were from plant growth regulators, followed by photosynthetic enhancement, cell or...

The level and distribution of the social benefits from public investment in Canadian wheat breeding research and extension activities are examined for the period 1946 to 1979. In addition, average and marginal rates of return are calculated. The results reveal that society has benefited...

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...
