Abstract

This study presents new estimates of supply and demand elasticities for U.S. multiproduct cash grain farms and estimates of input and output bias effects caused by public and private crop research, extension, and farmers' schooling. The study also shows that the social rate of return to public crop research is large—about 62 percent.
