This study applies a translog cost function to analyze factor demands in four U.S. wheat production regions. The results show that factor demands are inelastic across all regions. The interdependent relationships among inputs and the effects of price changes on the relative cost shares are...

The regional demand for feed grains is not directly observable. This study uses a programming model to derive a demand schedule for feed barley. The model is applied to a major barley producing region (North Dakota and Minnesota) and an important feed deficit region (California). Direct and...
