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...

Assessing U.S. Corn Production Technology

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...

Demand functions for teaching, research and extension (TRE) personnel in seven administrative units of U.S. agricultural experiment stations are estimated from panel data, decennial observations, 1950 to 1987. The results reveal that the demand for the services of TRE personnel has not declined...
