Multiproduct Supply and Input Demand in U.S. Agriculture

Two sets of U.S. agricultural output supply and input demand relationships, including cross‐price effects, are reported for five commodity groups and four variable input groups for the 1951–82 period. They are obtained by direct econometric estimation on U.S. data and by geographic aggregation from published econometric estimates for each of ten regions comprising the contiguous forty–eight states. The supply and demand formulations are specified on the assumptions of competitive behavior and an underlying normalized quadratic profit function. The effects of upward‐sloping input supply curves are examined at the national level.
