The information needed by a rational producer in a dynamic commodity market has many components. One is market data on prices and the current capital stock of the industry. Another component is the skill to combine these data into better decisions. In agriculture, prices and stocks are monitored and reported by the U.S.D,A. and Land-Grant Universities at little or not cost to farmers and ranchers. But the techniques for making better decisions are difficult to obtain.
