Efficiency effects of agricultural economics research in the United States
研究了美国农业经济学研究对农业效率的影响，发现社会科学研究有滞后但显著的效果，且技术推广对配置效率和技术效率的影响大于研发和社会科学研究。
Abstract Allocations of research funds across programs are often made for efficiency reasons. Social science research is shown to have small, lagged but significant effects on U.S. agricultural efficiency when public agricultural R&D and extension are simultaneously taken into account. Farm management and marketing research variables are used to explain variations in estimates of allocative and technical efficiency using a Bayesian approach that incorporates stylized facts concerning lagged research impacts in a way that is less restrictive than popular polynomial distributed lags. Results are reported in terms of means and standard deviations of estimated probability distributions of parameters and long‐run total multipliers. Extension is estimated to have a greater impact on both allocative and technical efficiency than either R&D or social science research.
