A test of the underinvestment, myopia and commodity bias hypotheses for U.S. agricultural research
通过构建美国经济非线性最优增长模型，检验了农业研究投资不足、基础研究相对应用研究投入过少以及商品间研究资源配置效率低下的三个假说，发现投资不足假说得到强支持，基础研究相对不足未获支持，作物研究比畜牧研究资金更短缺得到弱支持。
ABSTRACT Analysts of agricultural research policy in the United States of America have claimed that the overall level of public investment in agricultural research is less than what would be socially optimal, that the present composition of public research investment is excessively myopic in that too little basic research is performed relative to the level of applied research, and that the allocation of research resources among commodities is inconsistent with economic efficiency. A non‐linear optimal growth model of the U.S. economy was developed to analyse these propositions. Strong support was found for the claim that the overall level of investment has been inadequate. No support was found for the contention that basic research has been relatively underfunded compared to applied research. Weak support was found for the view that crop research has suffered from more acute underfunding than has livestock research.
