The Political Economy of Agricultural Research and Extension: Grants, Votes, and Reapportionment
分析影响美国各州对农业研究和推广财政支持的经济与政治因素，发现联邦拨款有刺激作用，而州议会重新分配和农民政治影响力也显著影响支出。
Abstract This paper seeks to identify the economic and political factors that produce state financial support for agricultural research and extension. State demand for research and extension services is found to be influenced not only by the level of farm income and population but also by measures of intergovernmental influence and the political effectiveness of farmers. Federal grants have “price” effects which stimulate state spending; the reapportionment of state legislatures mandated by the U.S. Supreme Court had a negative effect, while the ability of farmers to elect other farmers to the legislature increases state support for research and extension.
