英文文献摘要：
A time series supply analysis on corn plantings using annual data for 1960-82 helped predict participation in the 1983 feed grain (PIK) program. Of particular importance in the supply equation was a policy variable which measured both the attractiveness of feed grain programs and the requirements for reducing acreage.
