英文文献作者：Vasavada, Utpal
英文文献摘要：
A system of dynamic investment demand and output supply equations is consistently estimated utilizing recent advances in dynamic duality theory. Results indicate that labor, capital services, and land adjust sluggishly to relative price changes. This can be construed as a form of asset fixity within aggregate U.S. agriculture.
